    Acori Graminei Rhizoma is well known for the beneficial effects on CNS disorders in traditional medicine. Though it is frequently prescribed in formulations for brain tumors, the anti-glioma effect has not been examined. We used volatile oil of Acori Graminei Rhizoma (VOA) and human glioblastoma multiforme (GBM) cells in this study. We found that VOA exhibited greater growth suppression in p53 wild-type cells than p53 mutant cells and very low effect on fibroblasts and human glial HEB cells. Apoptosis was triggered by VOA with a caspase-dependent way in p53 wild-type A172 cells, while a caspase-independent way in p53 mutant U251 cells. Meanwhile, both A172 and U251 cells treated by VOA displayed autophagic features. Furthermore, p53 decrease was observed along with VOA-induced apoptosis and autophagy in A172 cells. VOA-induced autophagy was mediated through a p53/AMPK/mTOR signaling pathway in A172 cells, while an mTOR-independent signaling pathway in U251 cells. Finally, blockage of autophagy potentiated the proapoptotic effect in both A172 and U251 cells, indicating a protective role of autophagy in VOA-induced cell death. Together, VOA exhibited anti-tumor activity in human GBM cells and induced apoptotic cell death and protective autophagy, which is cell type specific and dependent on p53 status. PMID:26892186

    Acori graminei Rhizoma (AGR), the dry rhizoma of Acorus gramineus Soland (Araceae), has been used as an Asian traditional herbal medicine against senile dementia, stroke, and cardiovascular disease. Previous studies have revealed neuroprotective effects of AGR on neuronal damage and learning impairment, while mostly focused on the effect of volatile oil fraction of AGR. This study aimed to investigate the neuroprotective effects of different extract fractions from AGR against Alzheimer disease-like symptoms induced by Amyloid Beta (Aß) 1-42 intra-hippocampal injection. On day 7 after intra-hippocampal injection of saline or Aβ1-42, spatial memory was assessed by the first Morris water maze, followed by 3-week intra-gastric administration of saline or water extract, volatile oil fraction, or defatted decoction fraction of AGR respectively. Mice were subsequently subjected to the second Morris water maze task. Levels of Aβ1-42 and expressions of doublecortin and nestin in the hippocampus were examined using immunohistochemistry. Our results suggested that treatment with these different extract fractions from AGR could ameliorate cognitive impairment and down-regulate expressions of doublecortin and nestin in the hippocampus of Aβ1-42 injected mice, in which water extract and volatile oil fractions were more effective in spatial memory than defatted decoction fraction.

    Rhizoma Acori Tatarinowii is widely used in traditional Chinese medicine. In this study, three novel polysaccharides designated RATPW, RATPS1 and RATPS2 were isolated from Rhizoma Acori Tatarinowii by DEAE-52 cellulose chromatography. Their structures were characterized using physicochemical and spectral methods. Chemical analysis indicated that RATPW (6.5×10(3)Da) mainly composed of glucose and fructose. RATPS1 (1.5×10(5)Da) contained galactose and arabinose, while RATPS2 (5.3×10(4)Da) contained ∼49.5% galacturonic acid along with rhamnose, fructose, galactose, and arabinose. In vitro, RATPS2 showed the most significant scavenging activity on DPPH and hydroxyl radical. Three polysaccharides could protect the PC12 cells from H2O2-induced damage. Immunological tests indicated that both RATPW and RATPS2 significantly stimulated NO production and phagocytic activity in RAW264.7, and promoted splenocyte proliferation. These data suggested that polysaccharides RATPW and RATPS2 had the potential as novel natural sources of antioxidative and immunopotentiating agents. PMID:26344267

    Acori Tatarinowii Rhizoma (ATR), the rhizome of Acorus tatarinowii Schott, is being used clinically to treat neurological disorders. The volatile oil of ATR is being considered as an active ingredient. Here, α-asarone and β-asarone, accounting about 95% of ATR oil, were evaluated for its function in stimulating neurogenesis. In cultured PC12 cells, application of ATR volatile oil, α-asarone or β-asarone, stimulated the expression of neurofilaments, a bio-marker for neurite outgrowth, in a concentration-dependent manner. The co-treatment of ATR volatile oil, α-asarone or β-asarone, with low concentration of nerve growth factor (NGF) potentiated the NGF-induced neuronal differentiation in cultured PC12 cells. In addition, application of protein kinase A inhibitors, H89 and KT5720, in cultures blocked the ATR-induced neurofilament expression, as well as the phosphorylation of cAMP-responsive element binding protein (CREB). In the potentiation of NGF-induced signaling in cultured PC12 cells, α-asarone and β-asarone showed synergistic effects. These results proposed the neurite-promoting asarone, or ATR volatile oil, could be useful in finding potential drugs for treating various neurodegenerative diseases, in which neurotrophin deficiency is normally involved.

    To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.

    A novel and compact near-infrared (NIR) Raman system is developed using 785-nm diode laser, volume-phase technology holographic system, and NIR intensified charge-coupled device (CCD). Raman spectra and first derivative spectra of Rhizoma Dioscoreae are obtained. Raman spectra of Rhizoma Dioscoreae showed three strong characteristic peaks at 477.4cm -1, 863.9cm -1, and 936.0cm -1. The major ingredients are protein, amino acid, starch, polysaccharides and so on, matched with the known basic biochemical composition of Rhizoma Dioscoreae. In the first derivative spectra of Rhizoma Dioscoreae, distinguishing characteristic peaks appeared at 467.674cm -1, 484.603cm -1, 870.37cm -1, 943.368cm -1. Contrasted with Rhizoma Dioscoreae Raman spectra, in 600cm -1 to 800cm -1, 1000cm -1 to 1400cm -1 regions, changes in Rhizoma Dioscoreae Raman first derivative spectra are represented more clearly than Rhizoma Dioscoreae Raman spectra. So Rhizoma Dioscoreae raman first derivative spectra can be an accurate supplementary analysis method to Rhizoma Dioscoreae Raman spectra.

    In this study, direct ionization mass spectrometry (DI-MS) for rapid authentication of Gastrodiae rhizoma (known as Tianma in Chinese), a popular herbal medicine, has been developed. This method is rapid, simple and allows direct generation of characteristic mass spectra from the raw herbal medicines with the application of some solvents and a high voltage. The acquired DI-MS spectra showed that gastrodin, parishin B/parishin C and parishin, the major active components of Gastrodiae rhizoma, could be found only in genuine Gastrodiae rhizoma samples, but not in counterfeit samples, thus allowing rapid authentication of Gastrodiae rhizoma. Moreover, wild and cultivated Gastrodiae rhizoma could be classified and Gastrodiae rhizoma from different geographical locations could be differentiated based on their different intensity ratios of characteristic ions or principal component analysis (PCA). This method is simple, rapid, reproducible, and can be extended to analyze other herbal medicines. PMID:27619090

    Background: Pinelliae Rhizoma is a commonly used Chinese herb which will change brown during the natural drying process. However, sulfur fumed Pinelliae Rhizoma will get a better appearance than naturally dried one. Sulfur fumed Pinelliae Rhizoma is potentially toxical due to sulfur dioxide and sulfites formed during the fuming procedures. The odor components in sulfur fumed Pinelliae Rhizoma is complex. At present, there is no analytical method available to determine sulfur fumed Pinelliae Rhizoma simply and rapidly. To ensure medication safety, it is highly desirable to have an effective and simple method to identify sulfur fumed Pinelliae Rhizoma. Materials and Methods: This paper presents a novel approach using an electronic nose based on metal oxide sensors to identify whether Pinelliae Rhizoma was fumed with sulfur, and to predict the fuming degree of Pinelliae Rhizoma. Multivariate statistical methods such as principal components analysis (PCA), discriminant factorial analysis (DFA) and partial least squares (PLS) were used for data analyzing and identification. The use of the electronic nose to discriminate between different fuming degrees Pinelliae Rhizoma and naturally dried Pinelliae Rhizoma was demonstrated. Results: The electronic nose was also successfully applied to identify unknown samples including sulfur fumed samples and naturally dried samples, high recognition value was obtained. Quantitative analysis of fuming degree of Pinelliae Rhizoma was also demonstrated. The method developed is simple and fast, which provides a new quality control method of Chinese herbs from the aspect of odor. Conclusion: It has shown that this electronic nose based metal oxide sensor is sensitive to sulfur and sulfides. We suggest that it can serve as a supportive method to detect residual sulfur and sulfides. PMID:24914293

    Atractylodis Rhizoma is a traditional medicinal herb, which has antibacterial, antiviral, anti‑inflammatory and anti‑allergic, anticancer, gastroprotective and neuroprotective activities. It is widely used for treating fever, cold, phlegm, edema and arthralgia syndrome in South‑East Asian nations. In this study, 6 chemical compositions of Atractylodis Rhizoma were characterized by spectral analysis and their antiviral activities were evaluated in vitro and in vivo. Among them, atractylon showed most significant antiviral activities. Atractylon treatment at doses of 10‑40 mg/kg for 5 days attenuated influenza A virus (IAV)‑induced pulmonary injury and decreased the serum levels of interleukin (IL)‑6, tumor necrosis factor‑α and IL‑1β, but increased interferon‑β (IFN‑β) levels. Atractylon treatment upregulated the expression of Τoll‑like receptor 7 (TLR7), MyD88, tumor necrosis factor receptor‑associated factor 6 and IFN‑β mRNA but downregulated nuclear factor‑κB p65 protein expression in the lung tissues of IAV‑infected mice. These results demonstrated that atractylon significantly alleviated IAV‑induced lung injury via regulating the TLR7 signaling pathway, and may warrant further evaluation as a possible agent for IAV treatment.

    This dissertation is to determine the biopotency of hemostat which processed in different places by establishing a bioassay method of Bletillae Rhizoma based on the thrombin time. Contrast test is the main methodology. Specifically, the reference substance of Bletillae Rhizoma is determined by comparing with the control substance of vitamin K1 using thrombin time, which is calibrated the Bletillae Rhizoma. The hemostatic biopotency is calculated by using the method of "parallel line assay method based on quantitative responses" (3.3) from different processed products. It indicates that there is a strong linear correlation between Bletillae Rhizoma and control drugs (Y = 66.332-23.913X, R2 = 0.995 3). The hemostatic biopotency of Bletillae Rhizoma from different processed products ranged between 821.93-1 187.53 U x g(-1) shown in the paper, and all of them can meet the requirements of the test. The methodology has an appropriate instrument precision (RSD 3.8%), intermediate precision (RSD 4.6%), repeatability (RSD 3.2%) and stability (RSD 3.7%). Therefore, it can be turned out that the methodology which established in the dissertation is good at determinating the hemostatic biopotency of Bletillae Rhizoma and it is reliable, simple and repeatable.

The effect of the drugs on the cell division rate and cell cycle of IEC-6 cells was detected by FCM. Quantitative Real-time PCR (qRT-PCR) was used to analyze the effect of the drugs on mRNA of p2l and p53 related to IEC-6 proliferation. Western blot was used to analyze the effect of the drugs on p2l and p53 protein expressions of IEC-6 cells. Atractylodis Macrocephalae Rhizoma could increase p53, p21 mRNA and proteins expression in DFMO-treated IEC-6 cells. The combined administration of different ratios of Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix et Rhizoma could significantly down-regulate Atractylodis Macrocephalae Rhizoma's effect on p53, p21 mRNA and proteins expression in DFMO-treated IEC-6 cells and promote the proliferation of IEC-6 cells. The combined administration of Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix et Rhizoma could down-regulate Atractylodis Macrocephalae Rhizoma's effect on DFMO-treated intestinal epithelial cells (IEC-6).

    Cardiovascular diseases (CVDs) are among the leading causes of morbidity and mortality in both the developed and developing world. Rhizoma coptidis (RC), known as Huang Lian in China, is the dried rhizome of medicinal plants from the family Ranunculaceae, such as Coptis chinensis Franch, C. deltoidea C.Y. Cheng et Hsiao, and C. teeta Wall which has been used by Chinese medicinal physicians for more than 2000 years. In China, RC is a common component in traditional medicines used to treat CVD associated problems including obesity, diabetes mellitus, hyperlipidemia, hyperglycemia and disorders of lipid metabolism. In recent years, numerous scientific studies have sought to investigate the biological properties of RC to provide scientific evidence for its traditional medical uses. RC has been found to exert significant beneficial effects on major risk factors for CVDs including anti-atherosclerotic effect, lipid-lowering effect, anti-obesity effect and anti-hepatic steatosis effect. It also has myocardioprotective effect as it provides protection from myocardial ischemia-reperfusion injury. These properties have been attributed to the presence of bioactive compounds contained in RC such as berberine, coptisine, palmatine, epiberberine, jatrorrhizine, and magnoflorine; all of which have been demonstrated to have cardioprotective effects on the various parameters contributing to the occurrence of CVD through a variety of pathways. The evidence available in the published literature indicates that RC is a herb with tremendous potential to reduce the risks of CVDs, and this review aims to summarize the cardioprotective properties of RC with reference to the published literature which overall indicates that RC is a herb with remarkable potential to reduce the risks and damage caused by CVDs.

    Rhizoma Paridis saponins (RPS) with a good antitumor effect in clinical use showed low bioavailability and toxicity. Combination of Rhizoma Curcuma longa with RPS, which called LouHuang preparation (LH), not only overcame the RPS limitations but also improved its anticancer effect. The median lethal dose (LD₅₀) of LH in mice was 3410.9 mg/kg by oral acute toxicity test. LH relieved the inhibition of RPS on the gastric emptying (70.13 ± 4.80% vs. 49.12 ± 8.06%). As for the antitumor effect, the tumor weight/volume inhibition rate, tumor volume growth rate, and water/food efficiency ratio were calculated. LH had the highest inhibition ratio of 57.07 ± 2.97% for H22 model, 43.22 ± 0.72% for S180 model, and 46.8 ± 0.97% for EAC model, which were higher than RPS. Compared to ZiLongJin (ZLJ), a marked antitumor drug in China, LH also had the higher inhibition rate for tumor weight and tumor volume growth, which weaker than CTX. The water/food efficiency ratio reflected the difference of the quality life of the mice bearing tumor cells or not. CTX attenuated body weight gain and increased food efficiency ratio compared to control group. LH did not affect the body weight or water/food intake. The active part of LH was RPS and turmeric polysaccharides with the inhibition of 58% and 47% on H22 and S180 tumor models. The research provided theoretical and practical basis for LH application.

    Cimicifugae Rhizoma is a traditional herbal medicine used to treat various diseases in Korea, China and Japan. Cimicifugae Rhizoma is primarily derived from Cimicifuga heracleifolia Komarov or Cimicifuga foetida Linnaeus. Cimicifugae Rhizoma has been used as an anti-inflammatory, analgesic and antipyretic remedy. The present study was performed to evaluate the extracts of Cimicifugae Rhizoma on the morphology and viability of human stem cells derived from gingiva. Stem cells derived from gingiva were grown in the presence of Cimicifugae Rhizoma at final concentrations that ranged from 0.001 to 1,000 µg/ml. The morphology of the cells was viewed under an inverted microscope and the analysis of cell proliferation was performed using a Cell Counting kit-8 (CCK-8) assay on days 1, 3, 5 and 7. Under an optical microscope, the control cells exhibited a spindle-shaped, fibroblast-like morphology. The shapes of the cells in the groups treated with 0.001, 0.01, 0.1, 1 and 10 µg/ml Cimicifugae Rhizoma were similar to the shapes in the control group. Significant alterations in morphology were noted in the 100 and 1,000 µg/ml groups when compared with the control group. The cells in the 100 and 1,000 µg/ml groups were rounder, and fewer cells were present. The cultures that were grown in the presence of Cimicifugae Rhizoma at a concentration of 0.001 µg/ml on day 1 had an increased CCK-8 value. The cultures grown in the presence of Cimicifugae Rhizoma at a concentration of 10 µg/ml on day 7 had a reduced CCK-8 value. Within the limits of this study, Cimicifugae Rhizoma influenced the viability of stem cells derived from the gingiva, and its direct application onto oral tissues may have adverse effects at high concentrations. The concentration and application time of Cimicifugae Rhizoma should be meticulously controlled to obtain optimal results. PMID:26622366

    A response surface and Box-Behnken design approach was applied to augment polysaccharide extraction from the residue of Rhizoma gastrodiae. Statistical analysis revealed that the linear and quadratic terms for three variables during extraction exhibited obvious effects on extraction yield. The optimum conditions were determined to be a liquid-to-solid ratio of 54 mL/g, an extraction temperature of 74 °C, an extraction time of 66 min, and three extractions. These conditions resulted in a maximum Rhizoma gastrodiae polysaccharide (RGP) extraction yield of 6.11% ± 0.13%. Two homogeneous polysaccharides (RGP-1a and RGP-1b) were obtained using DEAE cellulose-52 and Sephadex G-100 columns. The preliminary characterization of RGP-1a and RGP-1b was performed using HPLC-RID, HPGPC, and FTIR. Tests of the immunological activity in vitro showed that the two polysaccharides could significantly stimulate macrophages to release NO and enhance phagocytosis in a dose-dependent manner. In particular, RGP-1b (200 μg/mL) and LPS (2 μg/mL) had almost the same influence on the NO production and phagocytic activity of RAW 264.7 macrophages (p > 0.05). All the data obtained indicate that RGP-1a and RGP-1b have the potential to be developed as a health food. PMID:27347944

    The purpose of this study was to investigate the antioxidant and anti-inflammatory effects of the combined extract of Rhei rhizoma and Coptidis rhizoma (RC-mix) in experimental model of acute reflux esophagitis. The antioxidant activity was assessed by in vitro 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. RC-mix was given at 100, 200, and 400 mg/kg body weight 2 h prior to induction of reflux esophagitis (RE). After 5 h, the effects of RC-mix treated rats were compared with those of normal and control rats. The representative flavonoid contents of RC-mix, such as sennoside A, epiberberine, coptisine, palmatine, and berberine, were detected using HPLC. The elevated esophageal mucosa damage was markedly ameliorated by RC-mix treatment in a dose-dependent manner. Furthermore, the administration of RC-mix reduced the increase of serum reactive oxygen species (ROS) and peroxynitrite (ONOO(-)). The improvement of superoxide dismutase (SOD) and heme oxygenase-1 (HO-1) levels were marked in the group given RC-mix. Moreover, the elevation of inflammatory mediators and cytokines by nuclear factor-kappa B (NF-κB) activation in control rats decreased by RC-mix pretreatment. These results indicate that RC-mix treatment reduces the pathological states of esophagitis via regulating NF-κB mediated inflammation related to oxidative stress. PMID:27239206

    To explore the antibacterial activity and mechanism of total alkaloids and berberine from Coptidis Rhizoma on Aeromonas hydrophila, and determine the effect of total alkaloids and berberine from Coptidis Rhizoma on minimum inhibitory concentrations, permeability and fluidity of cell membrane, conformation of membrane proteins and virulence factors of A. hydrophila. The results showed that both total alkaloids and berberine from Coptidis Rhizoma had antibacterial activities on A. hydrophila, with minimum inhibitory concentrations of 62.5 and 125 mg · L(-1), respectively. Total alkaloids and berberine from Coptidis Rhizoma could increase the fluidity of membrane, change the conformation of membrane porteins and increase the permeability of bacteria membrane by 24.52% and 19.66%, respectively. Besides, total alkaloids and berberine from Coptidis Rhizoma significantly decreased the hemolysis of exotoxin and the mRNA expressions of aerA and hlyA (P < 0.05, P < 0.01), the secretion of endotoxin and the mRNA expression of LpxC (P < 0.05, P < 0.01). The results suggested that the antibacterial activity of total alkaloids and berberine from Coptidis Rhizoma on A. hydrophila may be related to the bacteria membrane injury. They inhibited the bacterial growth by increasing membrane lipid fluidity and changing conformation of membrane proteins, and reduced the secretion of virulence factors of A. hydrophila to weaken the pathogenicity.

    β-asarone (BAS) is an active component of Acori graminei rhizoma, a traditional medicine used clinically in treating dementia and chronic stress in Korea. However, the cognitive effects of BAS and its mechanism of action have remained elusive. The purpose of this study was to examine whether BAS improved spatial cognitive impairment induced in rats following chronic corticosterone (CORT) administration. CORT administration (40 mg/kg, i.p., 21 days) resulted in cognitive impairment in the avoidance conditioning test (AAT) and the Morris water maze (MWM) test that was reversed by BAS (200 mg/kg, i.p). Additionally, as assessed by immunohistochemistry and RT-PCR analysis, the administration of BAS significantly alleviated memory-associated decreases in the expression levels of brain-derived neurotrophic factor (BDNF) and cAMP-response element-binding protein (CREB) proteins and mRNAs in the hippocampus. Also, BAS administration significantly restored the expression of Bax and Bcl-2 mRNAs in the hippocampus. Thus, BAS may be an effective therapeutic for learning and memory disturbances, and its neuroprotective effect was mediated, in part, by normalizing the CORT response, resulting in regulation of BDNF and CREB functions and anti-apoptosis in rats.

    The rapidly increasing diabetes mellitus (DM) is becoming a major public health issue globally; considerable progress has been made in the field of western hypoglycemic drug and insulin, but some shortages still exist. As one of the most important parts in complementary and alternative therapies, traditional Chinese medicine (TCM) performs a good clinical practice and is showing a bright future in the treatment of DM. TCM therapy has certain advantages of less toxicity and/or side effects, and Chinese herbal medicine which usually contains various active ingredients could provide multiple therapeutic effects. Huang Lian (Rhizoma coptidis, RC) is a herb frequently used in many traditional formulas for properties of "clearing damp-heat, quenching fire, and counteracting poison" in Asia for centuries. In this review, we summarize the application of RC in the treatment of DM from two aspects of contents. Firstly, theoretical principles are explained, including the properties and related records about RC in ancient references and modern pharmacological researches and pharmacokinetics on RC and its active components. Secondly, the clinical application of RC is mainly reviewed, such as applicable stage and syndrome, the reasonable dose range, the preparation formulations, and the toxicity and/or side effects and solutions to its adverse actions. This review provides scientific evidence about the effective components, pharmacological researches, and toxicity of RC, as well as introducing traditional Chinese medical theory and clinical experience, in order to guide clinician to use RC more suitably and reasonably in the clinical practice.

    Coptidis Rhizoma and Aconiti Kusnezoffii Radix represent hot Chinese medicine and cold Chinese medicine respectively. The purpose of this study is to observe the differentiation effect of Coptidis Rhizoma and Aconiti Kusnezoffii Radix on lewis lung cancer and compare effect of hot Chinese medicine and cold Chinese medicine on tumor progression. In this study, the rat serum containing Coptidis Rhizoma or Aconiti Kusnezoffii Radix was prepared to treat lewis lung cancer cells in vitro, and effects of the serum containing Coptidis Rhizoma or Aconiti Kusnezoffii Radix on cell differentiation, proliferation, adhesion, succinic dehydrogenase (SDH) activity and gap-junction intercellular communication (GJIC) were investigated. In vivo, the subcutaneous implant model and pulmonary metastasis model of lewis lung cancer were established. Tumor bearing mice were taken water decoction of coptis chinensis or aconite by intragastric administration bid for four weeks, and the influences of coptis chinensis and aconite on tumor progression were evaluated by body temperature, blood oxygen saturation, red cell ATPase, blood rheology, intratumor hypoxia, capillary permeability and GJIC. The results showed that the serum containing aconite could induce cell differentiation, inhibit cell proliferation and migration, promote SDH activity and GJIC in lewis lung cancer cells. The serum containing Coptidis Rhizoma increased cell adhesion and decreased SDH activity and GJIC without cell differentiation although it also suppressed cell proliferation. Aconiti Kusnezoffii Radix water decoction could keep body temperature, blood oxygen saturation, red cell ATPase and blood rheology, and improve intratumor hypoxia, capillary permeability and GJIC in tumor bearing mice, which led to slower tumor growth and less metastasis. Coptidis Rhizoma water decoction decreased body temperature, blood oxygen saturation, red cell ATPase, blood rheology and GJIC, and promoted intratumor hypoxia and capillary

Rats were randomly divided into three groups and intravenously injected with 50 mg x kg(-1) salvianolic acid B for the single SMRR extracts group, 0.5 mg x kg(-1) ferulic acid for the single CR extracts group and 50 mg x kg(-1) salvianolic acid B + 0.5 mg x kg(-1) ferulic acid for the SMRR and CR combination group. The blood samples were collected at different time points and purified by liquid-liquid extraction with ethyl acetate. With chloramphenicol as internal standard (IS), UPLC was adopted to determine concentrations of salvianolic acid B and ferulic acid. The pharmacokinetic parameters of salvianolic acid B and ferulic acid were calculated with WinNonlin 6.2 software and analyzed by SPSS 19.0 statistical software. The UPLC analysis method was adopted to determine salvianolic acid B and ferulic acid in rat plasma, including linear equation, stability, repeatability, precision and recovery. The established sample processing and analysis methods were stable and reliable, with significant differences in major pharmacokinetic parameters, e.g., area under the curve (AUC), mean residence time (MRT) and terminal half-life (t(1/2)). According to the experimental results, the combined application of SMRR and CR can significantly impact the pharmacokinetic process of their effective components in rats and promote the wide distribution, shorten the action time and prolong the in vivo action time of salvianolic acid B and increase the blood drug concentration and accelerate the clearance of ferulic acid in vivo.

    Background: Cimicifugae rhizoma was a Ranunculaceae herb belonging to the composite family, and the roots of C. rhizoma have been widely used in tradition Chinese medicine. Materials and Methods: Ultrasound-assisted extraction (UAE) of phenolic compounds from C. rhizoma. Caffeic acid (CA), isoferulic acid (IA), ferulic acid (FA), and total phenols were quantified by high-performance liquid chromatography-diode array detection and ultraviolet-visible spectrophotometer. Effects of several experimental parameters, such as ultrasonic power (W), extraction temperature (°C), and ethanol concentration (%) on extraction efficiencies of phenolic compounds from C. rhizoma were evaluated. Results: The results showed that the optimal UAE condition was obtained with ultrasonic power of 377.35 W, extraction temperature of 70°C, and ethanol concentration of 58.37% for total phenols, and ultrasonic power of 318.28 W, extraction temperature of 59.65°C, and ethanol concentration of 64.43% for combination of CA, IA, FA. Conclusions: The experimental values under optimal conditions were in good consistent with the predicted values, which suggested UAE is more efficient for the extraction of phenolic compounds from plant materials.

    This work was mainly studied the effects of the four alkaloids from Coptidis Rhizoma on the mouse peritoneal macrophages in vitro and preliminarily discussed the regulating mechanisms. The effect of alkaloids from Coptidis Rhizoma on the vitality of macrophages was measured by the MTT assay. The effect of alkaloids on the phagocytosis of macrophages was determined by neutral red trial and respiratory burst activity was tested by NBT. The expressions of respiratory-burst-associated genes influenced by alkaloids were detected by qRT-PCR. The conformation change of membrane protein in macrophages by the impact of alkaloids was studied by fluorospectro-photometer. Results showed that the four alkaloids from Coptidis Rhizoma could increase the phagocytosis of macrophages in different level and berberine had the best effect. Berberine, coptisine and palmatine had up-regulation effects on respiratory burst activity of mouse peritoneal macrophages stimulated by PMA and regulatory activity on the mRNA expression of PKC, p40phox or p47phox, whereas the epiberberine had no significant influence on respiratory burst. Moreover, alkaloids from Coptidis Rhizoma could change the conformation of membrane protein and the berberine showed the strongest activity. The results suggested that the four alkaloids from Coptidis Rhizoma might activate macrophages through changing the conformation of membrane protein of macrophages and then enhanced the phagocytosis and respiratory burst activity of macrophages. Furthermore, the regulatory mechanism of alkaloids on the respiratory burst activity of macrophages may be also related to the expression level of PKC, p40phox and p47phox.

    The present paper used many kinds of mensuration of FTIR spectroscopy to determine traditional Chinese drugs--rhizoma atractylodis macrocephalae. Comparing the horizontal attenuated total reflection-Fourier transform infrared spectra (HATR-FTIR) of xylem and outer layer parts of cuticle indicates that there are more butenolide and its derivatives in outer layer parts of cuticle. Much more chemical materials could be found in fresh sample than in drying sample, possibly due to the decreased amount of naphtha in the drying sample. The HATR-FTIR of xylem of rhizoma atractylodis macrocephalae and its confusable varieties were transformed into second derivative FTIR to make sure whether the peak location is consistent. As a result, the difference is significant.

    A quantitative analysis method of multi-components with a single marker (QAMS) for simultaneous determination of six marker compounds (one from phenolic acids and five from phthalides) in Chuanxiong Rhizoma was established by applying HPLC and using butylidenephthalide as the internal reference substance. And also the feasibility and accuracy of the established method for quality evaluation and application of Chuanxiong Rhizoma were investigated and validated. The analysis was performed with the mobile phase consisting of acetonitrile - 0.2% aqueous formic acid. The flow rate was 1.0 mL . min-1 and the column temperature was maintained at 30 °C. The detection wavelengths were set at 252 nm (for ferulic acid, Z-ligustilide, and butylidenephthalide) and 266 nm (for senkyunolide I, senkyunolide A, and coniferyl ferulate), separately, and 20 µL was injected for analysis with gradient elution. The results showed that there were no significant differences observed between the HPLC-QAMS method and the external standard method (RSD <5%). The relative correction factors were credible (RSD < 5%) in changed chromatographic conditions. The established HPLC-QAMS method can be accurately used for simultaneously evaluating and controlling the quality of Chuanxiong Rhizoma with multi-components. PMID:26521448

    Background: Rhizoma dioscoreae nipponicae is a perennial herb and its roots have been widely used in Traditional Chinese Medicine (TCM). Objective: To develop and optimize the extraction and hydrolysis technology of diosgenin from Rhizoma dioscoreae nipponicae. Materials and Methods: 1-methyl-3-(3-sulfopropyl)-imidazolium hydrogen sulfate ([PSMIM]HSO4), as a kind of functional ionic liquid, replaced inorganic acid, and was used in a one-step ultrasonic extraction and hydrolysis for the preparation of diosgenin (the aglycone of dioscin and an important precursor chemical in the pharmaceutical industry) from Rhizoma dioscoreae nipponicae, for the first time. The effects of various factors were evaluated. The obtained product was studied using high performance liquid chromatography (HPLC). Results: About 6.35 mg of diosgenin could be obtained from 2.0 g of raw material. Reusability and recycling of the ionic liquid were validated with fairly good results. The ionic liquid solution was reused four times, and the final extraction efficiency only decreased by 5%. Conclusion: In virtue of the obvious advantages of the green extraction and catalytic solvent, with further study, it is believed that this new one-step preparative method promises to replace the traditional methods.

    The combination of Glycyrrhizae Radix et Rhizoma and Aconiti Lateralis Radix Preparata can increase efficacy and decrease toxicity. This study started from the phenomena of protein self-assembly in the mixed decoction of Glycyrrhizae Radix et Rhizoma with Aconiti Lateralis Radix Preparata. The attenuated mechanism was explored between the combination of Glycyrrhizae Radix et Rhizoma and Aconiti Lateralis Radix Preparata by using the protein of Glycyrrhizae Radix et Rhizoma and aconitine which was the major toxic component of Aconiti Lateralis Radix Preparata. Glycyrrhizae Radix et Rhizoma protein with aconitine could form stable particles which particle mean diameter was (206.2 ± 2.02) nm and (238.20 ± 1.23) nm at pH 5.0 in normal temperature. Through the mouse acute toxicity experiment found that injection of aconitine monomer all mice were killed, and injection of Glycyrrhizae Radix et Rhizoma protein-aconitine particles with the same content of aconitine all mice survived. Survey the stability of Glycyrrhizae Radix et Rhizoma protein-aconitine shows that the colloid particles is stable at room temperature, and it has the possibility to candidate drug carrier. Glycyrrhizae Radix et Rhizoma protein can reduce the toxicity of aconitine through self-assembly.

    Rhizoma coptidis is a rhizome commonly used in traditional Chinese medicine. After oral administration of rhizoma coptidis extract, the plasma concentrations of its effective alkaloid constituents are so low that their systemic therapeutic actions cannot be explained. This study aimed to investigate the influence of lipopolysaccharide (LPS) on the pharmacokinetics of the rhizoma coptidis alkaloids. Pharmacokinetic experiments were performed with rats; both in vitro absorption and efflux experiments were carried out with everted rat gut sacs, whereas in vitro metabolism experiments were conducted with rat liver microsomes and intestinal S9 fractions. Mucosal changes were evaluated with light microscopy and transmission electron microscopy. The results showed that, in rat plasma, LPS pretreatment increased systemic alkaloid exposure. LPS pretreatment increased the in vitro absorption of the alkaloids and decreased their efflux. The efflux of vinblastine and rhodamine 123, P-glycoprotein substrates, also was decreased. The absorption of fluorescein isothiocyanate-labeled dextran (average molecular mass, 4 kDa), a gut paracellular permeability probe, was not influenced. Obvious damage was observed in the mucosa, but the tight junctions between epithelial cells remained intact. Intestinal, rather than hepatic, alkaloid metabolism was decreased. These findings indicated that LPS pretreatment increased systemic exposure to the alkaloids through enhancement of their absorption, which was related to decreased intestinal efflux and metabolism. The results add to the understanding of why rhizoma coptidis is active despite the low plasma concentrations of the rhizoma coptidis alkaloids measured in normal subjects and experimental animals.

    Corydalis Rhizoma is the dried tuber of Corydalis yanhusuo W.T. Wang which is used in traditional Chinese medicine for pain relief and blood activation. Before being used in the clinics, C. yanhusuo is traditionally processed through dry-frying or frying with vinegar, wine or salt. In this study, eleven alkaloids from Corydalis Rhizoma, namely protopine (1), α-allocryptopine (2), tetrahydrocolumbamine (3), coptisine (4), palmatine (5), berberine (6), dehydrocorydaline (7), D,L-tetrahydropalmatine (8), tetrahydroberberine (9), corydaline (10) and tetrahydrocoptisine (11) were simultaneously quantified using a newly developed high performance liquid chromatography-diode array detector (HPLC-DAD) method. The influence of vinegar and wine processing on the content of the main alkaloids of Corydalis Rhizoma was investigated. For this purpose, two common formulations with clinical application, namely the water decoction of Corydalis Rhizoma and its formula Jin Ling Zi San (combination of Corydalis Rhizoma and Toosendan Fructus) were studied. In the two water decoctions, wine and vinegar processing increased the amount of tertiary alkaloids. The differences were more pronounced for Jin Ling Zi San, in which case the content of all tertiary alkaloids (compounds 1, 2, 3, 8, 9, 10, 11) was increased by wine processing.

    Curculiginis Rhizoma (Curculigo orchioides GAERTN.) is a well-known Chinese herbal medicine, as well as an important Rasayana drug in India. Current criteria of quality control on this herb are to quantitatively analyze single compound curculigoside, which fail to comprehensively evaluate quality of this herb. In this paper, a simple and reliable HPLC coupled with diode array detector (DAD) method was developed to evaluate the quality of Curculiginis Rhizoma through establishing chromatographic fingerprint and simultaneously quantitating four phenolic compounds, orcinol glucoside, orcinol, 2,6-dimethoxybenzoic acid and curculigoside. The fingerprint displayed eleven common peaks, and the similarity index of different samples was in a range of 0.890-0.977. Validation of the method was acceptable, with 96.03-102.82% accuracy in recovery test and inter and intra-day precisions were less than 2%. This developed method by having a combination of chromatographic fingerprint and quantitation analysis could be applied to the quality control of Curculiginis Rhizoma.

    Rhizoma Coptidis, Cortex Phellodendri, and berberine were reported to inhibit Helicobacter pylori. However, the underlying mechanism remained elusive. Urease plays a vital role in H. pylori colonization and virulence. In this work, aqueous extracts of Rhizoma Coptidis, Cortex Phellodendri of different origins, and purified berberine were investigated against H. pylori urease and jack bean urease to elucidate the inhibitory capacity, kinetics, and mechanism. Results showed that berberine was the major chemical component in Rhizoma Coptidis and Cortex Phellodendri, and the content of berberine in Rhizoma Coptidis was higher than in Cortex Phellodendri. The IC50 values of Rhizoma Coptidis were significantly lower than those Cortex Phellodendri and purified berberine, of which Coptis chinensis was shown to be the most active concentration- and time-dependent urease inhibitor. The Lineweaver-Burk plot analysis indicated that the inhibition pattern of C. chinensis against urease was noncompetitive for both H. pylori urease and jack bean urease. Thiol protectors (L-cysteine, glutathione, and dithiothreithol) significantly protected urease from the loss of enzymatic activity, while fluoride and boric acid showed weaker protection, indicating the active-site sulfhydryl group was possibly responsible for its inhibition. Furthermore, the urease inhibition proved to be reversible since C. chinensis-blocked urease could be reactivated by glutathione. The results suggested that the anti-urease activity of Rhizoma Coptidis was superior to that of Cortex Phellodendri and berberine, which was believed to be more likely to correlate to the content of total alkaloids rather than berberine monomer. The concentration- and time-dependent, reversible, and noncompetitive inhibition against urease by C. chinensis might be attributed to its interaction with the sulfhydryl group of the active site of urease.

    This paper established a near-infrared spectroscopy quantitative model for simultaneous quantitative analysis of coptisine hydrochloride, dehydrocorydaline, tetrahydropalmatine, corydaline and glaucine in Corydalis Rhizoma. Firstly, the chemical values of the five components in Corydalis Rhizoma were determined by the reversed-phase high performance liquid chromatography (RP-HPLC) with UV detection. Then, the quantitative calibration model was established and optimized by fourier transformation near-infrared spectroscopy (NIRS) combined with partial least square (PLS) regression. The calibration model was evaluated by correlation coefficient (r), the root-mean-square error of calibration (RMSEC) and the root mean square of cross-validation (RMSECV) of the calibration model, as well as the correlation coefficient (r) and the root mean square of prediction (RMSEP) of prediction model. For the quantitative calibration model, the r, RMSEC and RMSECV of coptisine hydrochloride, dehydrocorydaline, tetrahydropalmatine, corydaline and glaucine were 0.941 0, 0.972 7, 0.964 3, 0.978 1, 0.979 9; 0.006 7, 0.003 5, 0.005 9, 0.002 8, 0.005 9; and 0.015, 0.011, 0.020, 0.010 and 0.022, respectively. For the prediction model, the r and RMSEP of the five components were 0.916 6, 0.942 9, 0.943 6, 0.916 7, 0.914 5; and 0.009, 0.006 6, 0.007 5, 0.006 9 and 0.011, respectively. The established near-infrared spectroscopy quantitative model is relatively stable, accurate and reliable for the simultaneous quantitative analysis of the five alkaloids, and is expected to be used for the rapid determination of the five components in crude drug of Corydalis Rhizoma.

    Yuzhu (Polygonati Odorati Rhizoma), Kangdingyuzhu (Polygonati Prattii Rhizoma), and zhugenqiyuzhu (Disporopsis Fuscopictae Rhizoma) are of the same family, but of different genera. They have all often used in Chinese Materia Medica (CMM) as Polygonati Odorati Rhizoma in China market. Three species of CMM are confused. For better application, we need to identify these plants accurately. This study use pharmacognosy technique and GC-MS analysis, three species of CMM were authenticated. In macroscopic characteristics, the fruit of Polygonati Odorati Rhizoma is blue-black, while the other two are maroon and dark purple orderly. Nodes of Polygonati Odorati Rhizoma are upward and light uplift, about 1 cm spacing, while the other are not. As for microscopic characteristics, the cortex of Polygonati Odorati Rhizoma only occupies about 1/5 of the radius of the transverse section with inconspicuous endodermis, which is much smaller than others. The type of vascular bundles of Polygonati Odorati Rhizoma is closed collateral, but the other is amphivasal. Raphides of calcium oxalate are scattered, but Raphides of the other two are like brooms and neat rows. GC-MS analysis of essential oil could provide different characteristics to distinguish three species. Twenty-three compounds were identified from essential oil of Polygonati Odorati Rhizoma and the main components were n-hexadecanoic acid (49.45%), while n-hexadecanoic acid of the other two are 23.92% and 9.45%. The content of n-hexadecanoic is strongly different. This research was aimed to establish a method by pharmacognosy and GC-MS analysis to identify three CMM and for providing scientifical data to ensure accuracy of origin of three species.

    In this paper, Rhodiolae Crenulatae Radix et Rhizoma extract,with high hygroscopic,was selected as research model, while lactose was selected as modifiers to study the effect of the grinding modification method on the hygroscopic. Subsequently, particle size distribution, scannin electron microscopy, infrared spectroscopy and surface properties were adopted for a phase analysis. The results showed that the modified extract, prepared by Rhodiolae Crenulatae Radix et Rhizoma extract grinding 5 min with the same amount of lactose UP2, which hygroscopic initial velocity, acceleration, and critical relative humidity moisture were less than that of Rhodiolae Crenulatae Radix et Rhizoma extract and the mixture dramatically. In addition, compared with the mixture, the size distribution of modified extract was much less, the microstructure was also difference, while the infrared spectroscopy and surface properties were similar with that of lactose. It is the main principle that lactose particle adhered to the surface of Rhodiolae Crenulatae Radix et Rhizoma extract after grinding mofication to decress the moisture obviously. PMID:25039174

    Fourier transform infrared spectroscopy (FT-IR) associated with second derivative infrared spectroscopy (SD-IR) and two-dimensional correlation infrared spectroscopy (2D-IR) are employed to analyze various processed products and different extracts of Rhizoma Coptidis. There is a shift of the peak of 1641 cm-1 of raw Rhizoma Coptidis after processed, which drifts to lower wave number. Peaks at 1508, 1387, 1363, 1332, 1274 and 1234 cm-1 barely change in most samples, except an obvious enhancement of these peaks after processed, suggesting that processed Rhizoma Coptidis may have higher content of berberine than raw material, which is corresponding to the results of correlation coefficients analysis. There are some differences in the absorption peaks in the range of 1800-1000 cm-1 in the SD-IR spectra, which have better resolution, of different processed products. 2D-IR spectra, which elevate the resolution further, can present more differences among the products in the range of 1300-800 cm-1 and 1800-1300 cm-1. Analysis of aqueous, ethanol and petroleum ether extracts of various processed products proves that there are distinctive differences of all auto-peaks in shapes and intensities in all of them. With the advantages of high resolution, high speed and convenience, FT-IR combined with 2D-IR can quickly and precisely distinguish various processed products of Rhizoma Coptidis and can be applied to predict the tendency of transformation of the complicated chemical mixture systems under heat perturbation.

    Rhizoma paridis saponins (RPS) played a good antitumor role in many clinical applications. However, low oral bioavailability limited its application. In this research, water extract of Curcuma (CW) significantly increased antitumor effect of Rhizoma paridis saponins (RPS). GC-MS was used to identify its polar composition. HPLC was applied for determination of the content of curcuminoids in CW. As a result, 47 analytes with 0.65% of curcuminoids were identified in CW. According to the in vivo anti-tumor data, the best proportion of curcuminoids in CW with RPS was 16:500 (w/w). Using this ratio, curcuminoids significantly increased absorption of RPS in the everted rat duodenum sac system. In addition, curcuminoids decreased the promotion of RPS on rhodamine 123 efflux. The effect of curcuminoids was similar to that of the P-gp inhibitor, cyclosporin A in combination with RPS. In conclusion, drug combination of water extract of Curcuma with RPS was a good method to increase the antitumor effect of RPS. This combination would be a potent anticancer agent used in the prospective application.

    This study aims to explore the effect of catnip Nepeta cataria (CNC) charcoal on the pharmacokinetics of the main alkaloids of Rhizoma Coptidis in vivo. Twenty-four rabbits were randomly divided into four groups and given oral administration of an aqueous extract of Rhizoma Coptidis (RCAE), RCAE plus CNC, RCAE plus activated carbon (AC), or distilled water, respectively. Plasma samples were collected after administration. The concentrations of berberine, coptisine, palmatine, and epiberberine in plasma were measured by high-performance liquid chromatography (HPLC). The pharmacokinetics data were calculated using pharmacokinetic DAS 2.0 software. The results showed that the area under the concentration-time curve (AUC) of berberine increased, while the AUC of coptisine, palmatine, and epiberberine decreased in the rabbits that received RCAE plus CNC. Meanwhile, the AUC of berberine, coptisine, palmatine, and epiberberine decreased in the group given RCAE plus AC. The difference of main pharmacokinetics parameters among the four groups was significant (P < 0.05). This study showed that CNC improved the bioavailability of berberine in comparison to AC and prolonged its release in comparison to RCAE alone. However, it decreased the bioavailability of coptisine, palmatine, and epiberberine. In comparison, AC uniformly declined the bioavailability of berberine, coptisine, palmatine, and epiberberine.

    Metabolomics was used to explore the mechanism of Rhizoma coptidis in treating type II diabetes mellitus. The rat model of type II diabetes mellitus was constructed by an injection of streptozocin (40 mg/kg), along with diets of fat emulsion. The rats were divided into four groups, the control group, the model group, the Rhizoma coptidis group (10 g/kg) and the metformin group (0.08 g/kg). After the treatment for 30 d, blood samples were collected to test biomedical indexes, and 24 h urine samples were collected for the metabolomics experiment. In the Rhizoma coptidis group, fasting blood glucose (FBG), total cholesterol (TC) and total plasma triglycerides (TG) were significantly decreased by 59.26%, 58.66% and 42.18%, respectively, compared with those in the model group. Based on gas chromatography-mass spectrometry, a urinary metabolomics method was used to study the mechanism of Rhizoma coptidis in treating diabetes mellitus. Based on the principal component analysis, it was found that the model group and control group were separated into two different clusters. The Rhizoma coptidis group was located between the model group and the control group, closer to the control group. Twelve significantly changed metabolites of diabetes mellitus were detected and identified, including 4-methyl phenol, benzoic acid, aminomalonic acid, and so on. After diabetic rats were administered with Rhizoma coptidis, 7 metabolites were significantly changed, and L-ascorbic acid and aminomalonic acid which related with the oxidative stress were significantly regulated to normal. The pharmacological results showed that Rhizoma coptidis could display anti-hyperglycemic and anti-hyperlipidemic effects. The Rhizoma coptidis had antioxidation function in preventing the occurrence of complications with diabetes mellitus to some extent. The work illustrates that the metabolomics method is a useful tool to study the treatment mechanism of traditional Chinese medicine.

    Biatractylolide was isolated from ethyl acetate extract of dried Atractylodis Macrocephalae Rhizoma root by multistep chromatographic processing. Structure of biatractylolide was confirmed by (1)H-NMR and (13)C-NMR. The IC50 on acetylcholinesterase (AChE) activity was 6.5458 μg/mL when the control IC50 value of huperzine A was 0.0192 μg/mL. Molecular Docking Software (MOE) was used to discover molecular sites of action between biatractylolide and AChE protein by regular molecular docking approaches. Moreover, biatractylolide downregulated the expression of AChE of MEF and 293T cells in a dose-dependent manner. These results demonstrated that the molecular mechanisms of inhibitory activities of biatractylolide on AChE are not only through binding to AChE, but also via reducing AChE expression by inhibiting the activity of GSK3β.

    Tetramethylpyrazine (TMP), a pharmacologically active component isolated from the rhizome of the Chinese herb Rhizoma Chuanxiong (Chuanxiong), has been clinically used in China and Southeast Asian countries for the prevention and treatment of cardiovascular diseases (CVDs) for about fifty years. The pharmacological effects of TMP on the cardiovascular system have attracted great interest. Emerging experimental studies and clinical trials have demonstrated that TMP prevents atherosclerosis as well as ischemia-reperfusion injury. The cardioprotective effects of TMP are mainly related to its antioxidant, anti-inflammatory, or calcium-homeostasis effects. This review focuses on the roles and mechanisms of action of TMP in the cardiovascular system and provides a novel perspective on TMP's clinical use. PMID:27314011

    Biatractylolide was isolated from ethyl acetate extract of dried Atractylodis Macrocephalae Rhizoma root by multistep chromatographic processing. Structure of biatractylolide was confirmed by 1H-NMR and 13C-NMR. The IC50 on acetylcholinesterase (AChE) activity was 6.5458 μg/mL when the control IC50 value of huperzine A was 0.0192 μg/mL. Molecular Docking Software (MOE) was used to discover molecular sites of action between biatractylolide and AChE protein by regular molecular docking approaches. Moreover, biatractylolide downregulated the expression of AChE of MEF and 293T cells in a dose-dependent manner. These results demonstrated that the molecular mechanisms of inhibitory activities of biatractylolide on AChE are not only through binding to AChE, but also via reducing AChE expression by inhibiting the activity of GSK3β.

    Rhizoma Paridis saponin (RPS) had been regarded as the main active components responsible for the anti-tumor effects of the herb Paris polyphylla var. yunnanensis (Franch.) Hand.-Mazz. In the present research, we set up a rat model of diethylnitrosamine (DEN) induced hepatoma to evaluate antitumor effect of RPS. After 20 weeks treatment, rats were sacrificed to perform histopathological examinations, liver function tests, oxidative stress assays and so forth. As a result, DEN-induced hepatoma formation. RPS alleviated levels of liver injury through inhibiting liver tissues of malondialdehyde (MDA) and nitric oxide (NO) formation, increasing superoxide dismutases (SOD) production, and up-regulating expression of GST-α/μ/π in DEN-induced rats. All in all, RPS would be a potent agent inhibiting chemically induced liver cancer in the prospective application.

    Methods to identify Pinelliae Tuber and Arisaematis Rhizoma are required because of frequent reciprocal substitution between these two herbal medicines and the existence of several closely related plant materials. As a result of the morphological similarity of dried tubers, correct discrimination of authentic herbal medicines is difficult by conventional methods. Therefore, we analyzed DNA barcode sequences to identify each herbal medicine and the common adulterants at a species level. To verify the identity of these herbal medicines, we collected five authentic species (Pinellia ternata for Pinelliae Tuber, and Arisaema amurense, A. amurense var. serratum, A. erubescens, and A. heterophyllum for Arisaematis Rhizoma) and six common adulterant plant species. Maturase K (matK) and ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit (rbcL) genes were then amplified using universal primers. In comparative analyses of two DNA barcode sequences, we obtained 45 species-specific nucleotides sufficient to identify each species (except A. erubescens with matK) and 28 marker nucleotides for each species (except P. pedatisecta with rbcL). Sequence differences at corresponding positions of the two combined DNA barcodes provided genetic marker nucleotides that could be used to identify specimens of the correct species among the analyzed medicinal plants. Furthermore, we generated a phylogenetic tree showing nine distinct groups depending on the species. These results can be used to authenticate Pinelliae Tuber and Arisaematis Rhizoma from their adulterants and to identify each species. Thus, comparative analyses of plant DNA barcode sequences identified useful genetic markers for the authentication of Pinelliae Tuber and Arisaematis Rhizoma from several adulterant herbal materials.

    Pharmacological activities of some natural products diminish and even disappear after purification. In this study, we explored the mechanisms underlying the decrease of acute oral toxicity of Coptidis Rhizoma extract after purification. The water solubility, in vitro absorption, and plasma exposure of berberine (the major active compound) in the Coptidis Rhizoma extract were much better than those of pure berberine. Scanning electron microscopy, laser scanning confocal microscopy (LSCM), and dynamic light scattering experiments confirmed that nanoparticles attached to very fine precipitates existed in the aqueous extract solution. The LSCM experiment showed that the precipitates were absorbed with the particles by the mouse intestine. High-speed centrifugation of the extract could not remove the nanoparticles and did not influence plasma exposure or acute oral toxicity. However, after extract dilution, the attached precipitates vanished, although the nanoparticles were preserved, and there were no differences in the acute oral toxicity and plasma exposure between the extract and pure berberine. The nanoparticles were then purified and identified as proteinaceous. Furthermore, they could absorb co-dissolved berberine. Our results indicate that naturally occurring proteinaceous nanoparticles in Coptidis Rhizoma extract act as concentration-dependent carriers that facilitate berberine absorption. These findings should inspire related studies in other natural products. PMID:26822920

HGE was optimized by response surface methodology (RSM) to obtain the maximum extraction efficiency of eight alkaloids. Separation was achieved on a Waters ACQUITY UPLC® BEH C18 column (50 × 2.1 mm(2), 1.7 μm) using gradient elution with a mobile phase consisting of acetonitrile and 0.2% formic acid in water. Quantification was performed with multiple reaction monitoring (MRM) mode using positive ESI as an interface. This is the first report of the simultaneous analysis of eight oxoisoaporphine alkaloids in Rhizoma Menispermi using a UPLC-MS/MS method; this analysis afforded good linearity, precision, and accuracy. Then, the method was successfully applied to determine the alkaloids in Rhizoma Menispermi from different sources.

    This study was designed to validate the correlation between integrated pharmacokinetic and therapeutic effects of alkaloids using bile processed Rhizoma Coptidis (BRC). Rats were divided into three groups: normal, disease model, model+BRC. Rats were induced to have an excessive heat syndrome. Rectal temperatures were collected at 0, 3, 6 and 9 h after single oral administration of the drugs. The plasma concentrations of three alkaloids were quantified at different times by UPLC-MS/MS after the administration of BRC. An approach of self-defined weighting coefficiency was created to the holistic pharmacokinetic profiles of alkaloids in BRC. The classified and integrated synthetic concentrations were obtained, and then the pharmacokinetic parameters of alkaloids were calculated from non-compartmental model analysis. The potential relationship between the integrated mean concentration of alkaloids and the antifebrile efficacy was investigated. The holistic t(max) of alkaloids was 1.11 h, the antifebrile effect of BRC at 3 h was improved over the model group. Double peaking appeared in the integrated blood concentration-time curve, the second t(max) of alkaloids was 4.82 h. The antifebrile effects of BRC at 3-6 h were significant, and the antifebrile effects at 6-9 h was decreased significantly. Dynamic variation of alkaloids of BRC in the body exhibited the similarity to the pattern of its antifebrile effect. PMID:27405174

    Rhizoma Coptidis (RC), commonly known as huanglian, is a herb frequently used in Traditional Chinese Medicine (TCM) prescriptions. Known to have “clearing damp-heat, quenching fire and counteracting poison” properties, it was widely used in the Chinese community in Singapore. Berberine, an alkaloid isolated from RC, is known to have a wide array of therapeutic effects including antimicrobial, antineoplastic, and hepatoprotective effects. In 1978, RC was implicated in causing neonatal jaundice (NNJ) and kernicterus in neonates suffering from glucose-6-phosphate dehydrogenase (G6PD) deficiency, leading to the banning of RC and berberine in Singapore. More than three decades later, accumulating evidence-based studies pointing to the safety of RC for general public and better understanding of G6PD deficiency, the Health Sciences Authority (HSA) in Singapore reviewed and lifted the prohibition on RC and berberine, turning a brand new chapter in the history of TCM in Singapore. This paper aims to review the safety of RC and berberine, using the prohibition of use and subsequent lifting of ban on RC and berberine in Singapore as an illustration to highlight the importance of evidence-based studies in Traditional Chinese Medicine (TCM).

    The present study aimed at exploring different roles of the same compound in different environment, using preparative HPLC, and the significance to investigating bio-active constituents in traditional Chinese medicine (TCM) on the basis of holism. In this study, the depletion of target component ferulic acid (FA) by using preparative HPLC followed by antioxidant activity testing was applied to investigate the roles of FA in Angelicae Sinensis Radix (DG), Chuanxiong Rhizoma (CX) and their combination (GX). The antioxidant activity was performed by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity testing. FA was successfully and exclusively depleted from DG, CX, and GX, respectively. By comparing the effects of the samples, it was found that FA was one of the main antioxidant constituents in DG, CX and GX, and the roles of FA were DG > CX > GX. Furthermore, the effects of FA varied at different doses in these herbs. This study provided a reliable and effective approach to clarifying the contribution of same compound in different TCMs to their bio-activities. The role of a constituent in different TCMs might be different, and a component with the same content might have different effects in different chemical environments. Furthermore, this study also suggested the potential utilization of preparative HPLC in the characterization of the roles of multi-ingredients in TCM. PMID:26073335

    Chuanxiong Rhizoma (CR), a well-known traditional Chinese medicine originated from the rhizome of Ligusticum chuanxiong Hort., was effective for treating various vascular diseases. To identify the metabolites of CR in vivo, the drug-containing urine samples of WZS-miniature pigs after orally administrated CR decoction were collected, after sequential column chromatography 17 metabolites (M1-M17) were isolated from the methanol extract of the urine samples. Their structures, including nine phthalides (M1-M9) and eight phenolic acids (M10-M17), were identified by spectroscopic means. Among them, 8 were new ones (M1-M6, M11-M12). On the basis of the structures of identified metabolites, seven original constituents, including 2 phthalides (senkyunolideI/H) and 5 phenolic acids (ferulic acid, isoferulic acid, caffeic acid, 3-hydroxycinnamoyl acid and 4-hydroxybenzonic acid) were deduced to be the major absorbed original constituents of CR in vivo. This is the first study on the metabolites of CR decoction in non-rodent animal (WZS-miniature pig), the results will give an insight into the metabolism profiles of phthalides and phenolic acids in CR decoction in vivo.

    A homogeneous polysaccharide was isolated and purified from Rhizoma Atractylodis Macrocephalae (RAM) and named PRAM2. Its average molecular weight was 19.6×10(3)Da and it was composed of rhamnose, xylose, arabinose, glucose, mannose and galactose in a ratio of 1: 1.3: 1.5: 1.8: 2.1: 3.2. In vitro experiments confirmed that PRAM2 presented an obvious effect to scavenge 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2,4,6-trinitrophenyl) (DPPH), superoxide anion and hydroxyl radical. In vivo experiments confirmed that PRAM2 could reduce the liver weight, liver index, aspartate transaminase (AST) and alanine aminotransferase (ALT) activities in the serum; meanwhile, PRAM2 could significantly reduce nitric oxide synthase (NOS) activity, and nitric oxide (NO) and malonaldehyde (MDA) contents in the liver tissues, and increase superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities. These results suggest that PRAM2 has a significant in vitro antioxidant activity and a protective effect on CCl4-induced liver injury in mice; the protective effect may be related to its anti-oxidation, its inhibition of NOS activity and NO level and its reduction of the production of free radicals.

    Hyperlipidemia is a major factor causing coronary heart disease and atherosclerosis. The high-density lipoprotein cholesterol (HDL-C) is a major indicator for measuring lipid levels. However, there is no an effective medicine that can obviously increase HDL-C at present. According to previous laboratory studies, atractylodes macrocephalae extracts could significantly increase HDL-C level. In this study, the metabolic hyperlipidemia rat model was established by feeding high-sugar and fat diets and alcohol-drinking to explore the effect and mechanism of atractylodes macrocephalae extracts on hyperlipidemia rats. According to the findingins, different doses of atractylodes macrocephalae extracts could reduce the levels of TC, TG, LDL-C, ACAT and increase the contents of LCAT, HDL-C. Particularly, the atractylodes macrocephalae extracts (100 mg · kg(-1) group showed increase in HDL-C by about 50% and significant declines in HMG-CoA reductase, TC, TG. In conclusion, Atractylodes Macrocephelae Rhizoma extracts could effectively regulate the dyslipidemia of hyperlipidemia rats, especially on HDL-C. Its mechanism may be related to reduction in cholesterol synthesis by inhibiting HMG-CoA reductase in livers and increase in lipid metabolism and transport by regulating LCAT and ACAT levels.

    Background: Atractylodis Rhizoma Alba (ARA) has been used in Korean folk medicine for constipation, dizziness, and anticancer agent. In the present study, we performed to test whether the methanolic extract of ARA has antioxidant and antiosteoclastogenesis activity in RAW 264.7 macrophage cells. Materials and Methods: Antioxidant capacities were tested by measuring free radical scavenging activity, nitric oxide (NO) levels, reducing power, and inducible nitric oxide synthase (iNOS) expression in response to lipopolysaccharides (LPS). Antiosteoclastogenesis activity was evaluated by performing tartrate-resistant acid phosphatase assay in RAW 264.7 macrophage cells. Results: The extract exerted significant 1,1-diphenyl-2-picrylhydrazyl and NO radical scavenging activity, and it exerted dramatic reducing power. Induction of iNOS and NO by LPS in RAW 264.7 cells was significantly inhibited by the extract, suggesting that the ARA extract inhibits NO production by suppressing iNOS expression. Strikingly, the ARA extracts substantially inhibited the receptor activator of NF-κB ligand-induced osteclastic differentiation of LPS-activated RAW 264.7 cells. The ARA extract contains a significant amount of antioxidant components, including phenolics, flavonoids and anthocyanins. Conclusion: These results suggest that the methanolic extract of ARA exerts significant antioxidant activities potentially via inhibiting free radicals and iNOS induction, thereby leading to the inhibition of osteoclastogenesis.

    To study the absorptive characteristics of aqueous extracts from Salviae Miltiorrhizae Radix et Rhizoma by in vitro rat everted intestinal sac model. Three representative ingredients in aqueous extracts from Salviae Miltiorrhizae Radix et Rhizome--protocatechuic aldehyde (PAL), posmarinic acid (RA) and salvianolic acid B (SAB), were selected as the study objects. An UPLC method was established to determine and measure their cumulative absorption amount, in order to explain the absorption characteristics of ingredients in different intestinal sections. According to the experimental result, RA and SAB showed the passive absorption in ileum, which conformed to the first-order absorption rate; with low and medium doses, they showed a zero-order absorption rate in jejunum, which was reflected in the coexistence of both positive and passive absorptions; PAL showed a passive absorption manner both in ileum and jejunum. According to the experiment for absorption in different intestinal sections, RA and SAB were mainly absorbed in jejunum, while PAL was absorbed mainly in ileum. All of the three ingredients in aqueous extracts from Salviae Miltiorrhizae Radix et rhizome--PAL, RA and SAB could be absorbed in intestines, but with differences in the absorption rate and mechanism, which indicated that the intestinal absorption of aqueous extracts from Salviae Miltiorrhizae Radix et rhizome was selectivity, instead of a simple semi-permeable membrane penetration process.

    A lab prototype CE-nanospray-MS platform with a high sensitivity porous sprayer was successfully applied in differential identification of Rhizoma coptidis in this paper. To obtain a stable and reliable nanospray, detailed optimizations about emitter geometry, buffer composition, emitter position, and spray voltage, as well as emitter cleanliness were discussed. Results showed that the reproducibility and sensitivity for separations of alkaloid standards were satisfactory using CE-nanospray-MS, which were also compared to ultra-HPLC (UHPLC)-MS. Their signal responds were at the same order of magnitude (intensities: 0.8 - 1.5 × 10(8) vs. 3.8 - 6.2 × 10(8) ), even though a 2 nL injection for CE was 2500-fold lower than UHPLC (5 μL injection). The absolute LOD results of CE-MS showed a remarkable superiority (18-24 fg), equal to 1000-fold lower than that of UHPLC-MS. Principal component analysis (PCA) of adulterated R. coptidis showed that this protocol had the ability to profile and qualify complex herb medicines, which also created a great potential for evaluation and qualification of rare and valuable Chinese medicines in future.

    Rhizoma Gastrodiae (Tianma) of different variants and different geographical origins has vital difference in quality and physiological efficacy. This paper focused on the classification and identification of Tianma of six types (two variants from three different geographical origins) using three dimensional synchronous fluorescence spectroscopy (3D-SFS) coupled with principal component analysis (PCA). 3D-SF spectra of aqueous extracts, which were obtained from Tianma of the six types, were measured by a LS-50B luminescence spectrofluorometer. The experimental results showed that the characteristic fluorescent spectral regions of the 3D-SF spectra were similar, while the intensities of characteristic regions are different significantly. Coupled these differences in peak intensities with PCA, Tianma of six types could be discriminated successfully. In conclusion, 3D-SFS coupled with PCA, which has such advantages as effective, specific, rapid, non-polluting, has an edge for discrimination of the similar Chinese herbal medicine. And the proposed methodology is a useful tool to classify and identify Tianma of different variants and different geographical origins.

    Hyperlipidemia is a major factor causing coronary heart disease and atherosclerosis. The high-density lipoprotein cholesterol (HDL-C) is a major indicator for measuring lipid levels. However, there is no an effective medicine that can obviously increase HDL-C at present. According to previous laboratory studies, atractylodes macrocephalae extracts could significantly increase HDL-C level. In this study, the metabolic hyperlipidemia rat model was established by feeding high-sugar and fat diets and alcohol-drinking to explore the effect and mechanism of atractylodes macrocephalae extracts on hyperlipidemia rats. According to the findingins, different doses of atractylodes macrocephalae extracts could reduce the levels of TC, TG, LDL-C, ACAT and increase the contents of LCAT, HDL-C. Particularly, the atractylodes macrocephalae extracts (100 mg · kg(-1) group showed increase in HDL-C by about 50% and significant declines in HMG-CoA reductase, TC, TG. In conclusion, Atractylodes Macrocephelae Rhizoma extracts could effectively regulate the dyslipidemia of hyperlipidemia rats, especially on HDL-C. Its mechanism may be related to reduction in cholesterol synthesis by inhibiting HMG-CoA reductase in livers and increase in lipid metabolism and transport by regulating LCAT and ACAT levels.

    Background Diabetic nephropathy has become the most common cause of morbidity and mortality in diabetic patients. Therefore, there is an urgent need for more effective and safer drugs for use in this condition. Purpose The aims of this study were to investigate the ameliorative effects of total saponin of Dioscoreae hypoglaucae rhizoma (TSD) on diabetic nephropathy and to explore the potential underlying mechanism(s). Methods Rats with streptozotocin-induced diabetes were orally treated with TSD at 40, 80, and 160 mg/kg/d for 12 weeks. At the end of the treatment, blood, urine, and kidneys were collected for biochemical and histological examination. Results The results demonstrated that TSD significantly decreased the fasting blood glucose, glycosylated hemoglobin, urinary protein, serum creatinine, and blood urea nitrogen levels in diabetic rats. The results of histological examinations showed that TSD ameliorated glomerular and tubular pathological changes in diabetic rats. Furthermore, TSD significantly prevented oxidative stress and reduced the renal levels of advanced glycation end products, transforming growth factor-β1, connective tissue growth factor, and tumor necrosis factor-α. Conclusion This study demonstrated the renoprotective effects of TSD in experimental diabetic nephropathy via a number of different mechanisms. PMID:26966352

    Ancient Chinese medicine treatises on Atractylodis Macrocephalae Rhizoma (AMR), the rhizome of Atractylodes macrocephala Koidz, indicated that it possessed an expectorant effect. However, in modern times, it is commonly used as a tocolytic agent. In this study, the components of AMR that are responsible for its expectorant and tocolytic effects were evaluated in order to clarify the differences in its application between ancient and modern times. A decoction of AMR was separated into five fractions, namely, volatile oil (VO), petroleum ether (PE), alcohol eluate from macroporous resin (AE), water eluate from macroporous resin (WE), and polysaccharides (PS), using various separation methods. The expectorant experiment indicated that the VO fraction, which mainly contains atractylone, produced an obvious expectorant effect. The experiment that assessed the irritability of uterine smooth muscle (USM) showed that the PE, which is mainly composed of atractylenolides, and the PS, which is mainly composed of inulin-type polysaccharides, were the active fractions for tocolysis, but the VO fraction had the opposite action. These data suggested that volatile oils are the key components responsible for the usage change of AMR in both ancient and current usage.

    Response surface method (RSM) was employed to optimize the extraction conditions of polysaccharides from Rhizoma Panacis Majoris (the rhizomes of Panax japonicus C. A. Mey. var. major (Burk.) C. Y. Wu et K. M. Feng) (RPMP), a well-known Chinese traditional medicine. In order to obtain the optimal processing parameters, a three-variable Box-Behnken designs (BBD) were applied for experimental designs. RSM analysis indicated the good correspondence between experimental and predicted values, the optimal conditions for the yield of polysaccharides were as follows: the ultrasound time is 31.15 min, extraction temperature is 92.50 °C, and the ratio of water to raw material is 40 mL/g. The maximum value (13.87 ± 0.16%) of the yield of polysaccharides was obtained under these optimal conditions. The molecular weight (MW) was determined to be 1.48 × 10(5)(±0.39%)Da by HPSEC-MALLS-RID chromatography system. FT-IR spectra demonstrated obvious characteristic peaks of polysaccharides. The antioxidant activities of RPMP were investigated including scavenging activity of hydrogen radicals, ABTS radicals, and free radicals of superoxide anion in vitro, and the results exhibited that RPMP had a good potential for antioxidant.

    Persicariae Rhizoma (PR) has been used as an anti-inflammatory and detoxification agent in Korea, and contains the biologically active dyes purple indirubin and blue indigo. Despite synthetic indigo showing genotoxic potential, thorough studies have not been carried out on the genotoxicity of PR. The potential genotoxicity of an aqueous extract of PR containing indigo (0.043%) and indirubin (0.009%) was evaluated using a standard battery of tests for safety assessment. The PR extract did not induce any genotoxic effects under the conditions of this study. The results of a reverse mutation assay in four Salmonella typhimurium strains and one Escherichia coli strain indicated that PR extract did not increase the frequency of revertant colonies in any strain, regardless of whether S9 mix was present or not. The PR extract also did not increase chromosomal aberrations in the presence or absence of S9 mix. Although slight signs of diarrhea were restrictedly detected in the mice treated with 2,000 mg/kg PR extract, no noteworthy changes in the frequency of micronucleated polychromatic erythrocytes were observed at doses ≤2,000 mg/kg in a bone marrow micronucleus test. These results indicate the potential safety of the PR extract, particularly if it is consumed in small amounts compared with the quantities used in the genotoxicity tests. PMID:27347027

    To study the toxicokinetics of bakuchiol, hepatic and renal toxicity in rats after single oral administration of Psoraleae Fructus and combined with Glycyrrhizae Radix et Rhizoma, in order to provide scientific evidences for clinical safe medication use. A total of 35 SD rats were randomly divided into seven groups: vehicle (distilled water) control group, Glycyrrhizae Radix et Rhizoma group, positive control (aristolochic acid A) group, Psoraleae Fructus (40 g x kg(-1)) group( both male and female rats), Psoraleae Fructus and Glycyrrhizae Radix et Rhizoma (40 +20) g x kg(-1) group (both male and female rats). HPLC-UV method was used to determine the concentration of bakuchiol in rat plasma at different time points after single oral administration. Plasma alanine transaminase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), plasma creatinine (Cr), N-acetyl-β-D-glucosaminidase (NAG) and kidney injury molecule 1 (Kim-1) were measured after administration for 24 h. The main toxicokinetics parameters of bakuchiol in rats exert significantly gender difference. When Psoraleae Fructus combination with Glycyrrhizae Radix et Rhizoma, the total area under the plasma concentration-time curve( AUC), C(max), and plasma clearance (CL) of bakuchiol were increased, respectively; CL, half-life (t½) were decreased, and T(max) were prolonged. The biochemical indicators (including ALT, AST, BUN, Cr and KIM-1 level) in different dose of Psoraleae Fructus groups, were found no statistically significant difference when compared with vehicle control group. The level of NAG in both Psoraleae Fructus and compatibility with Glycyrrhizae Radix et Rhizoma groups were significant increased (P < 0.05). There are obvious effects on toxicokinetics of bakuchiol in rats when Psoraleae Fructus combined with Glycyrrhizae Radix et Rhizoma. Renal toxicity induced by Psoraleae Fructus at high dose was observed after single oral administration and no liver damage in rats was found.

    Background: The dosage of herb ultrafine particle (UFP) depended on the increased level of its dissolution, toxicity, and efficacy. Objective: The dissolution, antibacterial activity, and cytotoxicity of Coptidis rhizoma (CR) UFP were compared with those of traditional decoction (TD). Materials and Methods: The dissolution of berberine (BBR) of CR TD and UFP was determined by high-performance liquid chromatography. The antibacterial activity of CR extract was assayed by plate-hole diffusion and broth dilution method; the inhibitory effect of rat serums against bacteria growth was evaluated after orally given CR UFP or TD extract. The cytotoxicity of CR extract was evaluated by 3-(4,5-dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide assay. Results: The dissolution amount of BBR from CR UFP increased 6–8-folds in comparison to TD at 2 min, the accumulative amount of BBR in both UFP and TD group increased in a time-dependent manner. The minimal inhibitory concentrations and minimal bactericidal concentrations of CR UFP extract decreased to 1/2~1/4 of those of TD extract. The inhibitory effect of rat serums against bacteria growth decreased time-dependently, and no statistical difference was observed between two groups at each time point. The 50% cytotoxic concentrations of UFP extract increased 1.66~1.97 fold than those of TD. Conclusions: The antibacterial activity and cytotoxicity of CR UFP increased in a dissolution-effect manner in vitro, the increased level of cytotoxicity was lower than that of antibacterial activity, and the inhibitory effect of rat serums containing drugs of UFP group did not improve. SUMMARY Ultrafine grinding process caused a rapid increase of BBR dissolution from CR.The antibacterial activity and cytotoxicity of UFP extract in vitro increased in a dissolution-effect manner, but the cytotoxicity increased lower than the antibacterial activity.The antibacterial activity of rat serums of UFP group did not improve in comparison to that

    The aims of the present study were to investigate the skin permeation and cellular uptake of a microemulsion (ME) containing total flavone of rhizoma arisaematis (TFRA), and to evaluate its effects on skin structure. Pseudo-ternary phase diagrams were constructed to evaluate ME regions with various surfactants and cosurfactants. Eight formulations of oil-in-water MEs were selected as vehicles, and in vitro skin-permeation experiments were performed to optimize the ME formulation and to evaluate its permeability, in comparison to that of an aqueous suspension. Laser scanning confocal microscopy and fluorescent-activated cell sorting were used to explore the cellular uptake of rhodamine 110-labeled ME in human epidermal keratinocytes (HaCaT) and human embryonic skin fibroblasts (CCC-ESF-1). The structure of stratum corneum treated with ME was observed using a scanning electron microscope. Furthermore, skin irritation was tested to evaluate the safety of ME. ME formulated with 4% ethyl oleate (weight/weight), 18% Cremophor EL (weight/weight), and 18% Transcutol P, with 1% Azone to enhance permeation, showed good skin permeability. ME-associated transdermal fluxes of schaftoside and isoschaftoside, two major effective constituents of TFRA, were 3.72-fold and 5.92-fold higher, respectively, than those achieved using aqueous suspensions. In contrast, in vitro studies revealed that uptake by HaCaT and CCC-ESF-1 cells was lower with ME than with an aqueous suspension. Stratum corneum loosening and shedding was observed in nude mouse skin treated with ME, although ME produced no observable skin irritation in rabbits. These findings indicated that ME enhanced transdermal TFRA delivery effectively and showed good biocompatibility with skin tissue.

    Purpose This study aims to investigate the additive effect of the Hedera helix (HH) and Rhizoma coptidis (RC) extracts mixture on antitussive and expectorant activities in animals. Materials and Methods The expectorant assay was performed with phenol red secretion in mice trachea. Mice or guinea pigs were randomly divided into groups of 8 each, including negative and positive control groups. After gastric administration of the test extracts in mice, 2.5% phenol red solution (0.2 mL) was intraperitoneally injected. Trachea was dissected and optical density of tracheal secretion was measured. After gastric administration of the test extracts in guinea pigs, the antitussive activities were assessed using a citric acid-induced cough measurement. Results The extracts of HH and RC significantly increased tracheal secretion and inhibited cough. The mixture of HH and RC extracts in a 1:1 concentration at a dose of 200 mg/kg showed a more potent effect on phenol red secretion (25.25±3.14) and cough inhibition (61.25±5.36) than the individual use of each extracts [phenol red secretion; HH 13.39±4.22 (p=0.000), RC 20.78±2.50 (p=0.010), cough inhibition; HH 9.89±4.14 (p=0.010), RC 30.25±7.69 (p=0.000)]. A 3:1 ratio mixture of HH to RC demonstrated an optimal expectorant effect (p<0.001), and this mixture showed expectorant and antitussive effects in a dose-dependent manner. Conclusion This study provides evidence for antitussive and expectorant effect of a 3:1 mixture of HH and RC, which may be a useful therapeutic option for respiratory diseases. PMID:25837191

    An herbal mixture prepared with Cinnamomi Ramulus, Anemarrhenae Rhizoma and Alpiniae Officinari Rhizoma (CAA) is used in oriental medicine for treating several ailments. The purpose of this study was to determine the mechanisms by which CAA elicits an antiinflammatory effect on nitric oxide (NO) production in the mouse macrophage cell line RAW 264.7 cells. The results indicated that lipopolysaccharide (LPS)-induced NO production was inhibited by CAA in a dose-dependent manner. Western blotting and RT-PCR analysis demonstrated that CAA decreased LPS-induced inducible nitric oxide synthase (iNOS) protein and gene expression in RAW 264.7 cells. Furthermore, CAA inhibited the LPS-induced DNA binding activity of nuclear factor-kappa B (NF-kappaB) and this effect was mediated through inhibiting the degradation of inhibitory factor-kappaBalpha (IkappaBalpha). Therefore, the results demonstrate that CAA inhibits LPS-induced production of NO and expression of iNOS by blocking NF-kappaB activation. CAA might be a potential therapeutic candidate for treating inflammatory diseases such as arthritis.

    Aim of the study Bear bile and Coptidis Rhizoma have been used in Chinese medicine with a long tradition in treating heat-diseases. Both bear bile and Coptidis Rhizoma are used to treat liver diseases in clinical practice of Chinese Medicine. Since bears are currently endangered, it raises the question whether the use of bear bile is ethical. To look for substitute for bear bile, the aim of this study is to compare the anti-fibrotic effects of Coptidis Rhizoma and its major component berberine with the actions of bear bile and its major compound tauroursodeoxycholic acid on experimental liver fibrosis in rats. Method Quality assessment was conducted with high performance liquid chromatography. The experimental liver fibrosis in rats was induced by carbon tetrachloride, alcohol, and bile duct ligation respectively. The biochemical criteria in the blood and tissue samples were measured to evaluate the anti-fibrotic properties and underlying mechanisms of the drugs. Results Coptidis Rhizoma Aqueous Extract (CRAE), berberine, and bear bile exerted anti-fibrotic properties on various liver fibrosis models in rats. CRAE and berberine significantly reduced the peroxidative stress in liver through increasing the superoxide dismutase enzyme activity. CRAE and berberine were able to excrete bilirubin products from the liver and protect hepatocytes from cholestatic damage. The effect of CRAE and berberine are comparable to that of bear bile. Conclusion Instead of using bear bile, CRAE and berberine can be potential substitutes in treating liver fibrosis. PMID:23190573

    In Chinese medicine, Shengjiang (Zingiberis Rhizoma Recens) and its processed products, such as Ganjiang (Zingiberis Rhizoma), Paojiang (Zingiberis Rhizoma Preparatum), and Jiangtan (Zingiberis Rhizoma Carbonisata), exert distinct efficacy clinically. This research tried to study the effects of extracts from Shengjiang and its processed products in RAW 264.7 macrophage cells. After incubation of the different ginger types in RAW 264.7 cells for 24 h, an aliquot of the culture was mixed with an equal volume of Griess reagent, and nitric oxide (NO) production was evaluated using a Griess assay. Lipopolysaccharide (LPS) was used as the positive control. Milli-Q water (MQW) was used as the solvent control. The results showed that NO production increased significantly in RAW 264.7 cells following the stimulation of LPS (0.05 μg mL−1), Shengjiang, Ganjiang, Paojiang, and Jiangtan (50 μg mL−1, 500 μg mL−1) separately compared with the MQW control (P < 0.01). The stimulation effects of Shengjiang and Ganjiang were significantly higher than those of Paojiang and Jiangtan at different concentrations (P < 0.01). The conclusion we could get from this research is that Shengjiang and its processed products could induce NO production in RAW 264.7 cells. PMID:25866540

    Alismatis Rhizoma has been used in East Asia as a traditional treatment for various illnesses and symptoms, and the presence of protostane-type triterpenes has been claimed to provide health benefits. To investigate the subchronic toxicity of triterpene-enriched extract from Alismatis Rhizoma (TEAR), a 90-day oral toxicity study was conducted in rats. Sprague-Dawley rats were randomly divided into four groups (10 rats/sex/group) and received doses of 0, 360, 720, and 1440 mg/kg/d of TEAR for 90 days. Daily clinical observations as well as weekly measurement of body weight and food consumption were conducted. Blood samples were obtained on day 91 to measure changes in hematology and biochemistry. Urine samples were collected on days 0 and 91 for urinalysis. At necropsy, selected organs were weighed and recorded, and histological examination was performed. No mortality or obvious treatment-related clinical signs, hematology, urinalysis parameters, and macroscopic or microscopic examinations were observed. Differences in weight gain, food consumption, biochemistry, and relative organ weight between the treated group and the control group were not considered treatment-related. On the basis of these findings, the no-observed-adverse-effect level for TEAR was 1440 mg/kg/d in both sexes. PMID:23684999

    Background Growing evidence shows that herb medicines have some anti-osteoporotic effects, the mechanism underlying is unknown. This study aims to investigate the therapeutic effect of Chinese herb supplements on rats that had osteoporosis-like symptom induced by ovariectomy (OVX). Methods OVX or sham operations were performed on virgin Wistar rats at three-month old, which were randomly divided into eight groups: sham (sham); OVX control group (OVX); OVX rats with treatments [either diethylstilbestrol (DES) or Semen Astragali Complanati decoction (SACD) or Rhizoma Cibotii decoction (RCD) or Herba Cistanches decoction (HCD) or Semen Allii Tuberosi decoction (SATD)]. Non-surgical rats were served as a normal control (NC). The treatments began 4 weeks after surgery, and lasted for 12 weeks. Bone mass and its turnover were analyzed by histomorphometry. Levels of protein and mRNA of osteoprotegerin (OPG) and receptor activator of nuclear factor κB ligand (RANKL) in osteoblasts (OB) and bone marrow stromal cells (bMSC) were evaluated by immunohistochemistry and in situ hybridization. Results Compared to OVX control, TBV% in both SACD and RCD groups was increased significantly, while TRS%, TFS%, MAR, and mAR were decreased remarkably in the SACD group, only TRS% decreased dramatically in the RCD group. No significant changes in bone formation were observed in either HCD or SATD groups. OPG levels in both protein and mRNA were reduced consistantly in OB and bMSC from OVX control rats, in contrast, RANKL levels in both protein and mRNA were increased significantly. These effects were substantially reversed by treatments with either DES or SACD or RCD. No significant changes in both OPG and RANKL expression were observed in OB and bMSC from OVX rats treated with SATD and HCD. Conclusions Our study showed that SACD and RCD increased bone formation by stimulating OPG expression and downregulating RANKL expression in OB and bMSC. This suggests that SACD and RCD may be

    In this study, two simple pretreatment methods were comprehensively evaluated for the determination of 135 pesticide residues in roots and rhizomes of Chinese herbal medicines (CHMs). The studied methodologies are (a) solid-phase extraction (SPE) and (b) Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS). For SPE, extraction solvents, SPE cartridges and types and volume of eluent were accessed and optimized. For QuEChERS, different versions, acetic acid concentration and dispersive solid-phase extraction (dSPE) sorbent materials were tested. SPE and QuEChERS were estimated in recovery range, the number of pesticides that were recovered ranging from 90% to 110% and expenses in Corydalis Rhizoma, Chuanxiong Rhizoma and Angelicae Sinensis Radix. QuEChERS method showed better performance than SPE. The method showed good linearity over the range assayed 0.9986-0.9999 (1-80ng/mL for 124 pesticides, 1-50ng/mL for 10 pesticides, 1-20ng/mL for satisfar). The matrix effect was compensated by matrix-based calibration curves with internal standard. The average recoveries of all pesticides were ranging from 70% to 120% at three levels of 10, 50 and 100ng/g with relative standard deviations less than 20%. The limits of quantification of the 135 pesticides in three matrices were 1-5ng/g, which were below the maximum residue levels (MRLs) established by the European Union. The verified QuEChERS method was successfully applied to the analysis of 65 actual samples from eight different types of roots and rhizomes of CHMs. Angelicae Sinensis Radix was the most susceptible to pesticides among these samples, and the most frequently detected pesticide was carbendazim with levels below MRLs. Metalaxyl, phorate, atrazine, diniconazole, coumaphos and paclobutrazol were also detected in some samples. PMID:26990739

    Separation of polar alkaloids by countercurrent chromatography (CCC) is challengeable due to their close partition behaviors in solvent system. In this paper, a two-stage method for isolation of epiberberine, jatrorrhizine, palmatine, coptisine, and berberine from Rhizoma coptidis was presented. The first stage separation performed on CCC was based on the principle of reactive extraction. Trifluoroacetic acid was acted as a modulator to selectively react with alkaloids, which changed their partition coefficients in solvent system. Purified epiberberine and other partially separated targets were eluted by ammonium adjusted mobile phase. In the second stage, four alkaloids were purified in pH-zone-refining CCC mode. All the targets collected were over 97% pure determined by HPLC. The method developed demonstrates performing of reactive extraction on standard CCC as an option for separation of polar alkaloids from medicinal plants.

    Timosaponin AIII (TAIII) exhibits extensive pharmacological activities and has been reported as a potent antitumour agent for various human cancers. In the present study, a potential industrial process for producing TAIII that involves biotransformation directly in the crude extract liquid of rhizoma anemarrhenae (RA) was developed. β-D-glycosidase was used to transform timosaponin BII (TBII) into TAIII, and monofactor experiments were conducted to optimise the enzymolysis conditions. In addition, AB-8 macroporous resin column chromatography, preparative liquid chromatography, and crystallisation technique were applied for yielding TAIII crystals with a purity > 97%. Approximately, 7 g of TAIII with a high purity of > 97% was obtained from 1 kg of RA through this five-step preparation method, which can be used to produce TAIII on a large scale. PMID:27055070

    To control the quality of Rhizoma Chuanxiong, a method based on high-performance liquid chromatography method coupled with diode array detection was developed for the quantitative analysis of six active ingredients using a single standard to determine multi-components and chemical fingerprint analysis for the first time. The separation was performed on an Agilent Zorbax SB-C18 column by gradient elution with methanol and aqueous phase (containing 0.5% glacial acetic acid) at a flow rate of 1.0 mL/min. The UV wavelength was set at 274 nm. This assay was fully validated with respect to precision, repeatability, and accuracy. All calibration curves showed good linearity (R(2) > 0.9994) within test ranges. The limit of detection and limit of quantification were lower than 0.01 and 0.03 μg/mL, respectively. The relative standard deviation for repeatability and the intermediate precision of six analytes were less than 1.6 and 2.5%, respectively, the overall recovery was 96.1-103.1%. In addition, fingerprint chromatography using hierarchical clustering analysis and similarity analysis was performed to differentiate and classify the samples. The method described here could provide a more comprehensive and reasonable scientific assessment of the quality of Rhizoma Chuanxiong. Therefore, the strategy is feasible, credible, and is easily and effectively adapted for evaluating the quality control of Rhizoma Chuanxiong. PMID:25619592

    Alismatis Rhizoma Decoction (ARD) is a classical Traditional Chinese Medicine (TCM) formula for treatment of vertigo with its long history of successful clinical effect. Since vertigo is a symptom of hyperlipidemia, this study aimed at evaluating the hypolipidemic effect of ARD in hyperlipidemic mice induced by high fat diet (HFD) and investigated the rationality of formula combination of Alismatis Rhizoma (AR) and Atractylodis Macrocephalae Rhizoma (AMR). Compared with control group, hyperlipidemic mice in AR and ARD groups displayed a reduction of the following parameters: body weight, liver and serum total cholesterol, triglyceride concentration, liver and spleen coefficients, activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT); whereas the serum HDL-cholesterol levels were significantly elevated in both AR and ARD groups. AR and ARD treatments significantly down regulated the expressions of 3-hydroxy-3-methylglutharyl-coenzyme A reductase (HMG-CoA reductase) and sterol regulatory element binding factor-2 (SREBF-2). These findings clearly provided evidences that the suppression on biosynthesis of cholesterol in liver may in part contribute to the hypolipidemic effects of ARD and AR. Since no significantly hypolipidemic effect of AMR was observed, the more prominent effect of ARD than that of AR indicated synergistic effects of AR and AMR, and confirmed the rationality of ARD formula.

    The ethanolic extracts of some Chinese traditional herb drugs, reported by Hong-Fu Wang et al. in China, could inhibit platelet aggregation as well as protect against radiation damage in mice, rat and rabbits. The inhibitory effects of the extracts of five Chinese drugs on the rate of platelet aggregation were observed in both in vitro and in vivo tests, averaging 23--53% in vitro and 46--69% in vivo. Antiradiation tests on mice vs. 7.5--8.0 Gy of [gamma]-radiation, using the herb drug extracts as protective agents, showed increasing survival rates by 8--50%. Based on Hong-Fu Wang's report, a search for the active constituents of these herb drugs in inhibiting platelet aggregation and protecting animals against radiation damage was started. In this research program, a Chinese traditional drug, Rhizoma Chuanxiong (rhizome of Ligusticum chuanxiong Hort.) was chosen. Three types of chemicals present in Rhizoma Chuanxiong, appeared promising for testing: 1-(5-hydroxymethyl-2-furyl)-9H-pyrido-(3,4-b)indole, 4-hydroxyl-3-butylidenephthalide and 5-hydroxyl-3-butylidenephthalide, and 4-hydroxyl-3-methoxycinnamyl 4-hydroxyl-3-methoxycinnamate. A total of 56 compounds of these derivatives has been synthesized and 30 were synthesized for the first time. The structure elucidation of these compounds was based on IR, [sup 1]H NMR and elemental analysis. From this research program, a very mild dehydrogenation method was developed. It was by using 2,3-dichloro-5,6-dicyanobenzoquinone in acetonitrile at ice bath temperature to dehydrogenate 1-(5-hydroxymethyl-2-furyl)-1,2,3,4-tetrahydro-9H-pyrido-(3,4-b)indole into 1-(5-hydroxymethyl-2-furyl)-9H-pyrido-(3,4-b)indole. This project showed for the first time that harmanoid alkaloids have the activity of inhibition of plate aggregation by 4 to 23 times that of aspirin. These results aid in establishing a relation between radiation protection in animals and prevention of platelet hyperaggregation.

    This study attempted to clarify the material basis for the detoxification of Rhizoma Zingiberis (RZ) on aconitine, an analgesic drug, by quantitatively assessing the influence of RZ on the in vitro intestinal concentration of aconitine using an everted gut sac model and by qualitatively identifying the components in the RZ extract. To quantify aconitine in rat everted gut sacs, both an accurate processing method and a sensitive detection method were required. We developed a three-step sample processing method to protect the components from decomposition and applied ultra-performance liquid chromatography coupled with triple quadrupole mass spectrometry (UPLC/TQMS) to quantify aconitine, glucose and digoxin. In addition, ultra-performance liquid chromatography coupled with linear ion trap mass spectrometry (UPLC/ITMS) was applied to detect the potential antidotal components in the RZ extract. Finally, the RZ extract reduced the level of aconitine in everted gut sacs, and eleven gingerols were successfully identified, which could be considered potential antidotal components for aconitine. This study demonstrated the application of two UPLC/MS methods for analyzing the material basis for the reciprocity between Chinese medicine components in everted gut sacs. PMID:25978042

    Cyperi Rhizoma (CR), the rhizome of Cyperus rotundus L., exhibits neuroprotective effects in in vitro and in vivo models of neuronal diseases. Nevertheless, no study has aimed at finding the neuroactive constituent(s) of CR. In this study, we identified active compounds in a CR extract (CRE) using bioactivity-guided fractionation. We first compared the anti-oxidative and neuroprotective activities of four fractions and the CRE total extract. Only the ethyl acetate (EA) fraction revealed strong activity, and further isolation from the bioactive EA fraction yielded nine constituents: scirpusin A (1), scirpusin B (2), luteolin (3), 6′-acetyl-3,6-diferuloylsucrose (4), 4′,6′ diacetyl-3,6-diferuloylsucrose (5), p-coumaric acid (6), ferulic acid (7), pinellic acid (8), and fulgidic acid (9). The activities of constituents 1–9 were assessed in terms of anti-oxidative, neuroprotective, anti-inflammatory, and anti-amyloid-β activities. Constituents 1, 2, and 3 exhibited strong activities; constituents 1 and 2 were characterized for the first time in this study. These results provide evidence for the value of CRE as a source of multi-functional neuroprotectants, and constituents 1 and 2 may represent new candidates for further development in therapeutic use against neurodegenerative diseases.

    The bioactive components extracted from Scutellariae radix and Rhei rhizoma (SR) have been commonly used to treat liver diseases. The aim of this study was to verify the underlying mechanisms and antifibrotic effects of ethanol extract from the herbal combinatorial formula (SRE) in a dimethylnitrosamine (DMN)-administered rat model, with functional proteome tools. Our results indicated that the hepatic collagen content and alpha-smooth muscle actin expression were obviously alleviated by treatment with SRE. Comprehensive proteomics revealed global protein changes, and the network analysis implied that SRE application would attenuate oxidative stress and cytoskeleton dysregulation caused by DMN exposure. Next, marked downregulation of antioxidant enzymes mediated by DMN treatment was restored in the presence of SRE, while SRE treatment contributed to decreased MDA content. Moreover, protein carbonylation and DNA adduction induced by oxidative stress finally leading to liver injury were also reduced under SRE administration. These findings demonstrate that SRE could effectively prevent hepatic fibrosis mainly through regulating the redox status, and subsequently modulating the modification of intracellular molecules. Our experiments might help in developing novel therapeutic strategies against oxidation-caused liver diseases. PMID:26133262

    This report describes the fabrication and the application of a novel carbon nanotube (CNT)-epoxy composite electrode as a sensitive amperometric detector for the capillary electrophoresis (CE). The composite electrode was fabricated on the basis of the in situ polycondensation of a mixture of CNTs and 1,2-ethanediamine-containing bisphenol A epoxy resin in the inner bore of a piece of fused silica capillary under heat. It was coupled with CE for the separation and detection of arbutin and bergenin in Bergeniae Rhizoma, a traditional Chinese medicine, to demonstrate its feasibility and performance. The two phenolic constituents were well separated within 10min in a 45cm capillary length at a separation voltage of 12kV using a 50mM borate buffer (pH 9.2). The CNT-based detector offered higher sensitivity, significantly lower operating potential, satisfactory resistance to surface fouling, and lower expense of operation, indicating great promise for a wide range of analytical applications. It showed long-term stability and reproducibility with relative standard deviations of less than 5% for the peak current (n=15).

    Nardostahyos Radix et Rhizoma (NRR; the root and rhizome of Nardostachys jatamansi DC.) is a widely used medicinal herb. Historically, NRR is being used for the treatment of cardiovascular and neurological diseases. To search for active ingredients of NRR, we investigated the vascular benefit of NRR volatile oil in (i) the vasodilation in rat aorta ring, and (ii) the release of nitric oxide (NO) and the phosphorylation of endothelial NO synthase (eNOS) in cultured human umbilical vein endothelial cells (HUVECs). By measuring the fluorescence signal in cultures, application of NRR volatile oil resulted in a rapid activation of NO release as well as the phosphorylation of eNOS: both inductions were markedly reduced by L-NAME. In parallel, the phosphorylation level of Akt kinase was markedly increased by the oil treatment, which was partially attenuated by PI3K/Akt inhibitor LY294002. This inhibitor also blocked the NRR-induced NO production and eNOS phosphorylation. In HUVECs, application of NRR volatile oil elevated the intracellular Ca(2+) level, and BAPTA-AM, a Ca(2+) chelator, reduced the Ca(2+) surge: the blockage were also applied to NRR-induced eNOS phosphorylation and NO production. These findings suggested the volatile oil of NRR was the major ingredient in triggering the vascular dilatation, and which was mediated via the NO production. PMID:25643147

    Pinelliae Rhizoma (PR) is a commonly used Chinese medicinal herb, but it has been frequently reported about its toxicity. According to the traditional Chinese medicine theory, processing can reduce the toxicity of the herbs. Here, we aim to determine if processing reduces the toxicity of raw PR, and to explore the underlying mechanisms of raw PR-induced toxicities and the toxicity-reducing effect of processing. Biochemical and histopathological approaches were used to evaluate the toxicities of raw and processed PR. Rat serum metabolites were analyzed by LC-TOF-MS. Ingenuity pathway analysis of the metabolomics data highlighted the biological pathways and network functions involved in raw PR-induced toxicities and the toxicity-reducing effect of processing, which were verified by molecular approaches. Results showed that raw PR caused cardiotoxicity, and processing reduced the toxicity. Inhibition of mTOR signaling and activation of the TGF-β pathway contributed to raw PR-induced cardiotoxicity, and free radical scavenging might be responsible for the toxicity-reducing effect of processing. Our data shed new light on the mechanisms of raw PR-induced cardiotoxicity and the toxicity-reducing effect of processing. This study provides scientific justifications for the traditional processing theory of PR, and should help in optimizing the processing protocol and clinical combinational application of PR.

    This study investigated the anti-methicillin-resistant Staphylococcus aureus (anti-MRSA) activity and chemical compositions of ether extracts from Rhizoma Polygoni Cuspidati (ET-RPC). Significant anti-MRSA activities of ET-RPC against MRSA252 and MRSA clinical strains were tested in in vitro antibacterial experiments, such as inhibition zone diameter test, minimal inhibitory concentration test, and dynamic bacterial growth assay. Subsequently, 7 major compounds of ET-RPC were purified and identified as polydatin, resveratrol-4-O-d-(6'-galloyl)-glucopyranoside, resveratrol, torachryson-8-O-glucoside, emodin-8-O-glucoside, 6-hydroxy-emodin, and emodin using liquid chromatography - electrospray ionization - tandem mass spectrometry. After investigation of anti-MRSA activities of the 7 major compounds, only emodin had significant anti-MRSA activity. Further, transmission electron microscopy was used to observe morphological changes in the cell wall of MRSA252, and the result revealed that emodin could damage the integrity of cell wall, leading to loss of intracellular components. In summary, our results showed ET-RPC could significantly inhibit bacterial growth of MRSA strains. Emodin was identified as the major compound with anti-MRSA activity; this activity was related to destruction of the integrity of the cell wall and cell membrane. PMID:25966789

    Alzheimer's disease (AD) is an age-related neurodegenerative disease. Extensive in vitro and in vivo experiments have proved that the decreased activity of the cholinergic neuron is responsible for the memory and cognition deterioration. The alpha7 nicotinic acetylcholine receptor (α7-nAChR) is proposed to a drug target of AD, and compounds which acting as α7-nAChR agonists are considered as candidates in AD treatment. Chinese medicine CoptidisRhizoma and its compounds are reported in various anti-AD effects. In this study, virtual screening, docking approaches and hydrogen bond analyses were applied to screen potential α7-nAChR agonists from CoptidisRhizome. The 3D structure of the protein was obtained from PDB database. 87 reported compounds were included in this research and their structures were accessed by NCBI Pubchem. Docking analysis of the compounds was performed using AutoDock 4.2 and AutoDock Vina. The images of the binding modes hydrogen bonds and the hydrophobic interaction were rendered with PyMOL1.5.0.4. and LigPlot+ respectively. Finally, N-tran-feruloyltyramine, isolariciresinol, flavanone, secoisolariciresinol, (+)-lariciresinol and dihydrochalcone, exhibited the lowest docking energy of protein-ligand complex. The results indicate these 6 compounds are potential α7 nAChR agonists, and expected to be effective in AD treatment.

    Persicariae Rhizoma (PR) is the dried stem parts of Persicaria tinctoria H. Gross (Polygonaceae), and has been traditionally used as anti-inflammatory and detoxifying agent. In the present study, the effects of PR aqueous extracts on ligation-induced experimental periodontitis (EPD) and associated alveolar bone loss in rats were examined. Following the induction of EPD in rats, PR extracts were orally administered once a day for 10 days, and the changes and gains in body weight, alveolar bone loss and total aerobic bacterial counts of buccal gingiva were observed with histopathological analysis. In addition, anti-inflammatory effects were evaluated by monitoring myeloperoxidase (MPO) activities, and interleukin (IL)-1β and tumor necrosis factor (TNF)-α contents, and anti-oxidant effects were investigated by measuring inducible nitric oxide synthase (iNOS) activities and malondialdehyde (MDA) levels. Bacterial proliferation, periodontitis and associated alveolar bone loss induced by ligature placement were significantly and dose-dependently inhibited by the treatment with PR extracts. The inhibitory effects of 200 mg/kg PR were similar to those of 5 mg/kg indomethacin on ligation-induced periodontitis and associated alveolar bone losses in this study. The results suggest that PR effectively inhibits ligature placement-induced periodontitis and alveolar bone loss in rats via antibacterial, antioxidative and anti-inflammatory activities.

Meanwhile, Rhizoma Paridis saponins (RPS) as natural products have been found to show strong antitumor activity, while its anti-cancer mechanism is not clear. To search for potential metabolite biomarkers of this model, serum metabonomics approach was applied to detect the variation of metabolite biomarkers and the related metabolism genes and signaling pathway were used to deduce the antitumor mechanisms of RPS. As a result, ten serum metabolites were identified in twenty-four mice including healthy mice, non-treated cancer mice, RPS-treated cancer mice and RPS-treated healthy mice. RPS significantly decreased tumor weight correlates to down-regulating lactate, acetate, N-acetyl amino acid and glutamine signals (p < 0.05), which were marked metabolites screened according to the very important person (VIP), loading plot and receiver operating characteristic curve (ROC) tests. For the analysis of metabolic enzyme related genes, RPS reversed the aerobic glycolysis through activating tumor suppressor p53 and PTEN, and suppressed FASN to inhibit lipogenesis. What's more, RPS repressed Myc and GLS expression and decreased glutamine level. The regulating PI3K/Akt/mTOR and HIF-1α/Myc/Ras networks also participated in these metabolic changes. Taken together, RPS suppressed ATP product made the tumor growth slow, which indicated a good anti-cancer effect and new angle for understanding the mechanism of RPS. In conclusion, this study demonstrated that the utility of (1)H NMR metabolic profiles taken together with tumor weight and viscera index was a promising screening tool for evaluating the antitumor effect of candidates. In addition, RPS was a potent anticancer agent through inhibiting cancer cellular metabolism to suppress proliferation in hepatoma H22 tumor murine, which promoted the

    It is hypothesized that Rhizoma Coptidis (RC) alkaloids exert their hypolipidemic effects primarily by targeting the gastrointestinal tract and liver. Thus, this study was conducted to evaluate the antihyperlipidemic mechanisms of RC alkaloids (at a daily dose of 140mg/kg for 35days) in high-fat and high-cholesterol induced hyperlipidemic B6 mice. After treatment, serum lipid parameters were determined, the expression of lipid metabolism related genes and pathways such as the sterol regulatory element binding proteins (SREBPs) and bile acid signaling in mice were also investigated. Meanwhile, Illumina sequencing was used to investigate the differences in gut microbiota of B6 mice. The results indicated that RC alkaloids reduced the body weight gain and serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), total bile acids (TBA) and lipopolysaccharide of B6 mice. Liver fat deposition and epididymal adipose cell size were also deceased in therapy group. RC alkaloids feeding significantly promoted the abundance of Sporobacter termitidis, Alcaligenes faecalis, Akkermansia muciniphila in the gut of mice, whereas, the abundance of Escherichia coli, Desulfovibrio C21_c20, Parabacteroides distasonis was suppressed. The observed antihyperlipidemic effects of RC alkaloids can also be attributed to their action as agonists of FXR and TGR5, activators for SREBP2, LDLR, UCP2 and CYP7A1, inhibitors of HMGCR, TXNIP, TLR4 and JNK. Therefore, this study expands current knowledge on hypolipidemic mechanisms of RC alkaloids and presents new evidence supporting a key role for RC alkaloids as regulators of lipid homeostasis by modulation gut microbiota and hepatic lipid metabolism.

    Rheumatoid arthritis (RA) is a common chronic autoimmune and incurable disease. The aim of the present study was to investigate the therapeutic effect and mechanism of the total saponins of Rhizoma Dioscorea nipponica (TSRDN) in RA. A collagen induced-arthritis (CIA) rat model was established. CIA rats were randomly divided into three groups and lavaged with an equal volume of solvent (CIA group), TSRDN (25 mg/kg/day, RDN group) and tripterygium (TP; 12 mg/kg/day, TP group) for 21 days, respectively. Normal rats served as a control group. Hematoxylin-eosin (HE) staining was used to observe the histopathological injury of synovial tissues. The level of CD31, which used for marking and counting, micro vessel density (MVD) and the expression levels of vascular endothelial growth factor (VEGF) and signal transducer and activator of transcription 3 (STAT3) were detected by immunohistochemical analysis. Additionally, the DNA-binding activity of nuclear factor-κB (NF-κB) was determined using an ELISA kit. HE staining showed obvious synovial hyperplasia, inflammatory cell infiltration, pannus formation, cartilage and bone erosion in the CIA group rats. In addition, compared with control group, the level of MVD, the expression of VEGF and STAT3, and the DNA-binding activity of NF-κB were all increased in CIA group rat synovial tissue (all P<0.01); however, TSRDN or tripterygium were able to inhibit these changes (all P<0.01). It was speculated that TSRDN may prevent angiogenesis by inhibiting the expression of STAT3 and the DNA-binding activity of NF-κB p65, thereby potentially improving CIA.

    As complicated mixture systems, active components of Chuanxiong Rhizoma are very difficult to identify and discriminate. In this paper, the macroscopic IR fingerprint method including Fourier transform infrared spectroscopy (FT-IR), the second derivative infrared spectroscopy (SD-IR) and two-dimensional correlation infrared spectroscopy (2DCOS-IR), was applied to study and identify Chuanxiong raw materials and its different segmented production of HPD-100 macroporous resin. Chuanxiong Rhizoma is rich in sucrose. In the FT-IR spectra, water eluate is more similar to sucrose than the powder and the decoction. Their second derivative spectra amplified the differences and revealed the potentially characteristic IR absorption bands and combined with the correlation coefficient, concluding that 50% ethanol eluate had more ligustilide than other eluates. Finally, it can be found from 2DCOS-IR spectra that proteins were extracted by ethanol from Chuanxiong decoction by HPD-100 macroporous resin. It was demonstrated that the above three-step infrared spectroscopy could be applicable for quick, non-destructive and effective analysis and identification of very complicated and similar mixture systems of traditional Chinese medicines.

    A sensitive and selective liquid chromatography-tandem mass spectrometry method has been developed and validated for simultaneous quantitation of 10 alkaloids (dauricine, daurisoline, N-desmethyldauricine, dauricicoline, dauriporphinoline, bianfugecine, dauricoside, stepholidine, acutumine and acutumidine) from Rhizoma Menispermi in rat plasma. After addition of internal standard (verapamil), plasma samples were pretreated by a single-step protein precipitation with acetonitrile. Chromatographic separation was performed on a Waters BEH C18 column with gradient elution using a mobile phase composed of acetonitrile and water (containing 0.1% formic acid) at a flow rate of 0.3 mL/min. The analytes were detected without interference in the multiple reaction monitoring (MRM) mode with positive electrospray ionization. The validated method exhibited good linearity over a wide concentration range (r≥0.9914), and the lower limits of quantification were 0.01-5.0 ng/mL for all the analytes. The intra-day and inter-day precisions (RSD) at three different levels were both less than 13.4% and the accuracies (RE) ranged from -12.8% to 13.5%. The mean extraction recoveries of analytes and IS from rat plasma were all more than 77%. The validated method was successfully applied to a comparative pharmacokinetic study of 10 alkaloids in rat plasma after oral administration of Rhizoma Menispermi extract.

    Rhizoma Paridis saponins combined with turmeric (RT) showed well anti-hepatocarcinoma activities in our previous research. The aim of this study was to investigate the progression of the biochemical response to RT and capture metabolic variations during intragastric administration of their compatibility. In the experiment, histopathological examination and (1)H NMR method were developed and validated for the metabolic profiling of RT intervention in H22 tumor growth. Data were analyzed with principal components analysis (PCA) and partial least-squares discrimination analysis (PLS-DA). As a result, Rhizoma paridis saponins (RPS) or RT induced inflammatory cell infiltration in tumors. RT also mediated the tumor microenvironment to promote anti-tumor immunity of mice. RT significantly inhibited tumor growth rate through suppressing levels of amino acids containing alanine, asparagine, glutamine, putrescine, and sarcosine, lipid compounds, and carbohydrates like myo-inositol and arabinose in the tumor tissues. In conclusion, these results uncovered unexpectedly poor nutritional conditions in the RT-treated tumor tissues whose effect was stronger than RPS's. Therefore, RT could be a novel anticancer agent that targets on cancer metabolism through starving tumors reducing viability of cancer cells.

    In Florida, rhizoma peanut (RP; Arachis glabrata Benth.), a tropical legume, combines the attributes of excellent nutritive value, competitive ability with tropical grasses, and high animal performance. The objective of this study was to determine the effects of spring N fertilization (0 vs 35 kg/ha) and summer stocking rate (1.5 and 2.5 bulls/ha) on herbage mass, nutritive value, herbage allowance, and diet botanical composition of grazed RP-grass swards and their interaction with growth and development of bulls (Senepol, and Brahman or Angus). The study was conducted in 1995 and 1996 at the USDA, ARS, Subtropical Agriculture Research Station in Brooksville, FL. Nitrogen was applied in April of each year, and all pastures were stocked with 1.5 bulls/ha until approximately July of each year, when stocking rate was increased on half the pastures to 2.5 bulls/ha. Herbage mass (HM, kg/ha), herbage allowance (HA, kg/kg BW), nutritive value (CP and in vitro organic matter digestibility [IVOMD]), and diet botanical composition (fecal microhistological) readings were determined. Animal measurements included total and seasonal (spring vs summer), ADG, hip height (cm), scrotal circumference (SC, cm), and plasma urea nitrogen (PUN, mg/dL). Herbage mass (3.0 +/- 0.12 Mg/ha and 3.4 +/- 0.13 Mg/ha in 1995 and 1996, respectively) was not affected by nitrogen fertilization or stocking rate but was affected by season (P < 0.05) due to increased plant growth rate associated with summer rainfall. Stocking rate did affect herbage availability, but it never fell below 3 kg/kg BW, indicating herbage availability was never limiting. Crude protein (200 to 140 g/kg) and IVOMD (650 to 540 g/kg) were not affected by treatment, but declined (P < 0.001) from spring until fall. Treatments also had no effect on diet botanical composition. Summer ADG averaged about 0.2 kg/d lower than spring ADG, due, in part, to seasonal declines in nutritive value. Because herbage allowance was never limiting

    Total flavonoid tablet from Anemarrhenae Rhizoma (Zhimu tablet), which was made of total polyphenol components extracted from the dried rhizome of Anemarrhena asphodeloides Bge. (Zhimu in Chinese), is a novel traditional Chinese medicine prescribed for the treatment of diabetes. Mangiferin (MF) and neomangiferin (NMF) are the two main components detected and determined in Zhimu tablet, accounting for 8.9% of the total weight of each tablet. In the present study, high performance liquid chromatography (HPLC) coupled with time-of-flight (TOF) tandem mass spectrometry (MS) was applied to characterize the metabolites of MF and NMF in rat plasmas collected at different time points after oral administration of Zhimu tablet at a dose of 3.63g/kg (corresponding to 270mg/kg MF). Accurate mass measurement was used to determine the elemental composition of metabolites and thus to confirm the proposed structures of identified metabolites. Time points of appearance of some metabolites, such as isomers, were also taken into account during the structure confirmation. A total of 21 potential metabolites were found in rat plasma at different time points, and the metabolic pathways in vivo were involved in hydrolysis, methylation, glucuronide conjugation, glycoside conjugation, sulphation, dehydration and isomerisation. Furthermore, a selective and accurate LC-MS assay method was developed and validated for the quantification of MF in plasma. Semi-quantification of main conjugated metabolites was also performed in order to describe the dynamic metabolism profiles of polyphenol components in Zhimu tablet. MF concentration in plasma reached 1.36±0.47μgmL(-1) about 5.0h after oral administration of Zhimu tablet, which showed a 3.24- and 4.91-fold increase in plasma maximum concentration and area under the concentration-time curve (AUC) from 0 to 24h of MF compared with those for rats administered with free MF, respectively. The results indicated that the pharmacokinetic processes and

    A method for the identification and determination of the polar amino components without ultraviolet activity in traditional Chinese medicines was developed. With Rhizoma Arisaematis as the object of this study, using pre-column derivatization with phenyl isothiocyanate (PITC) as the derivatization reagent, compounds were separated and identified on a C18 column (100 mm x 2.1 mm, 3.5 µm) by ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). A total of 20 components, including 18 amino acids and 2 amine compounds were identified. Furthermore, after the optimization of the derivatization conditions, 15 amino acids were determined by high performance liquid chromatography (HPLC) on Diamonsil C18 column (250 mm x 4.6 mm, 5 µm), detected at 254 nm and gradiently eluted by acetonitrile and 0. 05 mol/L ammonium acetate-acetic acid (pH 6. 5) as the mobile phases. The results of methodological study demonstrated that the method can meet the requirements of the determination. All calibration curves expressed good linearity: Glu, Try in the range of 2-100 mg/L, Arg in the range of 6-300 mg/L, others in the range of 0. 8-40 µg/L, with the correlation coefficients ≥ 0. 999 5. The average recovery of this method was among 95%-105% and the RSD was less than 3%. The developed method was successfully applied to quantitative determination of amino compounds in 12 batches of Rhizoma Arisaematis samples. The method is simple, sensitive, accurate, and can be used for rapid identification and determination of amino components in traditional Chinese medicines.

    A rapid NIRS method for determination of macrozamin in Heterosmilacis japonicae rhizoma (HJR), and the total content of oxymatrine and matrine (OMT + MT) as well as the total content of oxysophocarpine and sophocarpine (OSC + SC) in sophorae flavescens radix (SFR) was developed to explore the application feasibility of NIRS for the quality assurance system of Chinese patent drugs. The contents of macrozamin in HJR samples, and OMT + MT and OSC + SC in SFR samples were determined by HPLC as reference values. The NIR spectra of the samples were measured in a diffused reflection mode. The different characteristic wavebands and pretreatment methods were optimized. The quantitative calibration models between the NIR spectra and the content reference values of marker components in HJR and SFR samples, were established with partial least square method, and further optimized through the cross validation and external validation. The contents of macrozamin in 88 batches of HJR samples were over the range of 0.36-12.88 mg · g(-1). The total contents of OMT + MT and OSC + SC in 75 batches of SFR samples were over the range of 8.87-66.31 and 2.30-15.11 mg · g(-1), respectively. The performance of the final models for macrozamin, OMT + MT and OSC + SC was evaluated well according to correlation coefficients (r), root mean square error of cross-validation (RMSECV) and root mean square error of prediction (RMSEP). The R2 values of the cross-validation for macrozamin, OMT + MT and OSC + SC were 0.9025, 0.9491 and 0.9137, and those of RMSECV were 0.961, 2.45 and 0.724 mg · g(-1) respectively.

    A counter-current chromatography (CCC)-solid phase extraction (SPE)-CCC system with high preparative capacity was used to realize rapid one-run systematic separation of natural products, in which two six-port valves and the SPE cartridge served as the interface. In the orthogonal separation system, equal column volumes of TEB-300A and TEB-300B were employed for the first dimension (1st-D) and second dimension (2nd-D), respectively. An optimized solid-phase column (25 mm × 10 mm i.d.) packed with Oasis HLB materials acted as the trapping SPE column. The analyte-focusing effect of the trapping column associated with the considerable preparative capacities of 1st-D and 2nd-D using totally different solvent systems significantly facilitated this one-run systematic separation of natural product. Therefore, this proposed approach was successfully applied to isolate chemical compounds from the crude extract of Rhizoma Chuanxiong. As a result, 11 compounds with widely different polarities were separated by running CCC for only one time. More importantly, this hyphenated strategy could serve as a rapid and efficient systematic pathway for the separation of natural products.

    Migraine is one of the common and frequently encountered diseases. The study proves that 5-hydroxytryptamine (5-HT) receptor, plays an important role in the occurrence of migraine. Rat striatum was used for preparation of the cell membrane stationary phase (CMSP) in our experiments. The cell membrane chromatography (CMC)-offline-HPLC system was applied to specifically recognize the components from the drug pair of Chuanxiong Rhizoma and Angelicae Dahuricae Radix, which interact with the receptors on CMSP. The dissociation equilibrium constant (KD) was measured in a rat striatum/CMC system, performed by continuously pumping sumatriptan, a 5-HT1D agonist, ranging from 2.42 x 10(-8) to 4.84 x 10(-7) mol · L(-1) through a CMC column, and the capacity factors (k') were recorded. The KD value obtained from the model was (4.59 ± 0.33) x 10(-6) mol · L(-1) for imperatorin, and the rat model of migraine induced by nitroglycerin was applied to validate the pharmacological effects of the drug pair. The results indicated that the CMC method could be a quick and efficient way for characterizing the drug-receptor interactions in vitro. PMID:26084175

    The effects of fibrous root of Rhizoma Coptidis (FRC) and its main alkaloids on non-specific immunity and disease resistance of common carp were investigated. The fish were randomly assigned to seven groups: normal control group (NC), groups treated with 12.5 g/kg FRC (FRC-L), 25 g/kg FRC (FRC-M), 50 g/kg FRC (FRC-H), 0.78 g/kg total alkaloids (TA), 0.78 g/kg berberine (BBR), and 0.78 g/kg coptisine (Cop), respectively. Results showed that the activities of myeloperoxidase, lysozyme and respiratory burst were significantly elevated after treated with FRC-M, FRC-H, TA, BBR and Cop, and the complement C3 level and phagocytic activity were significantly increased in FRC-M, TA and BBR treated groups compared with NC group. The real-time PCR analysis indicated that FRC, TA, BBR and Cop could up-regulate the mRNA expression of IL-1β, TNF-α, lysozyme-c and C3, but down-regulate that of IL-10 in the head kidney of common carp. Besides, FRC-M, FRC-H, TA, BBR and Cop significantly enhanced the survival rate of common carp infected with Aeromonas hydrophila, when compared to NC group. It was concluded that the FRC could enhance the non-specific immunity and disease resistance of common carp and the main alkaloids might contribute to these effects. PMID:27090624

    Fo-Shou-San (FSS) is an ancient and classic formula comprised of Angelicae Sinensis Radix (Danggui, DG) and Chuanxiong Rhizoma (Chuanxiong, CX) in a weight ratio of 3:2 with nourishing blood and dissipating blood stasis activities for the treatment of blood deficiency and blood stasis. In this study, a ultra-high-performance liquid chromatography coupled with a triple quadrupole electrospray tandem mass spectrometry (UHPLC-TQ-MS/MS) method was developed for simultaneous quantification of three aromatic acids (chlorogenic acid, caffeic acid, ferulic acid) and six phthalides (senkyunolide I, senkyunolide H, senkyunolide A, butylphthalide, ligustilide and butylidenephthalide) in DG, CX and FSS. The nine components were simultaneously determined within 10min. The proposed method was fully validated in terms of linearity, sensitivity, precision, repeatability as well as recovery. The results showed that there were significant differences in their contents of DG and CX, and there were remarkable differences between the theorized content and observed content in FSS. The content of each component in formulae was not just the simple addition among its content in the single herbs. These research results might be helpful to illustrate the drug interactions during decocting process of herb pair according to the quantity changes of these marker compounds, which would lay foundation to further reveal the compatibility rule of the herb pair and other related formulae.

    Raw material examination is a critical process in the industrial production of traditional Chinese medicine (TCM); high accuracy and minimal time consumption are both required. In this study, near-infrared (NIR) spectroscopy was applied to improve the quality control efficiency of Rhizoma paridis. Partial least squares regression (PLSR) was first used to develop quantitative calibration models, and the discriminant analysis model was established to qualitatively discriminate the qualified samples from the unqualified samples. These two established NIR models were applied for real-time release testing (RTRT) of R. paridis. R. paridis saponins (RPS) ≥ 0.6% and moisture ≤ 12% were used as the quantitative releasing criteria of RTRT according to the Chinese Pharmacopoeia. Qualified samples classified by the discriminant analysis model were deemed to meet the qualitative releasing criterion of RTRT. Using the established quantitative model, 24 samples were allowed to be released to the subsequent production processes with 100% accuracy. For the qualitative RTRT analysis, three samples were misclassified as the unqualified class and were released unsuccessfully, the accuracy of the qualitative RTRT was 90%. Therefore, the quantitative RTRT was more feasible for actual manufacturing processes. Based on this study, a rapid and effective quantitative NIR spectroscopic method was proposed for the RTRT of R. paridis. The combination of RTRT and NIR spectroscopy could be a potential tool to improve the quality control efficiency of R. paridis.

    Three active compounds, senkyunolide-I, senkyunolide-H and ferulic acid (FA), were successfully isolated and purified from the extracts of Rhizoma Chuanxiong by counter-current chromatography (CCC). Based on the principle of the partition coefficient values (k) for target compounds and the separation factor (α) between target compounds, the two-phase solvent system that contains n-hexane-ethyl acetate-methanol-water at an optimized volume ratio of 3:7:4:6 v/v was selected for the CCC separation, and the lower phase was employed as the mobile phase in the head-to-tail elution mode. In a single run, 400 mg of the crude extract yielded pure senkyunolide-I (6.4 mg), senkyunolide-H (1.7 mg) and FA (4.4 mg) with the purities of 98, 93 and 99%, respectively. The CCC fractions were analyzed by high-performance liquid chromatography, and the structures of the three active compounds were identified by MS and (1)H NMR.

    Semen Ziziphi spinosae (Suanzaoren in China) and Radix et Rhizoma Salviae miltiorrhizae (Danshen in China) are conventional herbal drugs in traditional Chinese medicine and have been used widely for the treatment of insomnia. In the present study, the sedative-hypnotic activity of the active fractions extracted from Suanzaoren and Danshen were studied using the method of pentobarbital-induced sleep in the mouse model. Qualitative analysis of the standardized extracts was carried out by HPLC-DAD. The results showed that the water extract of Suanzaoren (SWE) (400 and 800 mg/kg body wt.) and the ether extract of Danshen (DTT) (300 and 600 mg/kg body wt.) can shorten sleep latency significantly, increase sleeping time and prolong movement convalescence time induced by sodium pentobarbital (55 mg/kg body wt.) administration in mice. Furthermore, the combination of SWE and DTT showed significant synergistic effect (p<0.05) in decreasing sleep latency and increasing sleeping time, but not in prolonging the movement convalescence time, which might be helpful for energy recovery in the treatment of insomnia. The results suggest that SWE, DTT, and the combination of SWE and DTT possess significant sedative-hypnotic activity, which supports the popular use of Suanzaoren and Danshen for treatment of insomnia and provide the basis for new drug discovery. Furthermore, the results demonstrate that the combination of SWE and DTT may be preferable for the treatment of insomnia. PMID:19682877

    Stroke is among the leading causes of death and severe disability worldwide. Flavonoids have been extensively used in the treatment of ischemic stroke by reducing lactate dehydrogenase levels and thereby enhancing blood perfusion to the ischemic region. Here, we used ultrafiltration high-performance liquid chromatography coupled with diode array detection and mass spectrometry for the rapid screening and identification of flavonoids from five Chinese medicinal herbs: soybean, Radix pueraria, Flos pueraria, Rhizoma belamcandae, and Radix astragali. Using PC12 cells as a suitable in vitro model of toxicity, cell viability was quantitated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The results showed that the extracts of soybean and the six major components, namely, acetyldaidzin, malonylgenistin, daidiain, glycitin, genistin, and acetylcitin; the extract of R. pueraria and its main component daidzein; the extract of F. pueraria and its three major components, tectorigenin, tectoridin, and tectorigenin-7-O-xylosylglucosid; and the extract of R. belamcandae and its main component, tectoridin, were strong lactate dehydrogenase inhibitors. Also, the components of R. astragali showed no bioactivity. These findings indicate that the ultrafltration high-performance liquid chromatography coupled with diode array detection and mass spectrometry method could be utilized in rapid screening and separation of bioactive compounds from a complex matrix.

    A sensitive and specific liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) method has been developed and validated for the identification and quantification of five protoberberine alkaloids, which are berberine, palmatine, coptisine, epiberberine and jatrorrhizine, in rat plasma using tetrahydroberberine as an internal standard. Following solid-phase extraction, the analytes were separated by linear gradient elution on a Shim-pack ODS (4.6 [mu]m, 150 mm × 2.0 mm i.d.) column and analyzed in selected ion monitoring (SIM) mode with a positive electrospray ionization (ESI) interface using the respective [M]+ and [M + H]+ ions, [M]+ = 336 for berberine; 320 for coptisine; 336 for epiberberine; 338 for jatrorrhizine; 352 for palmatine and [M + H]+ = 340 for the internal standard. The method was validated over the concentration range of 0.31-20 ng mL-1 for all the five protoberberine alkaloids. Within-batch and between-batch precisions (R.S.D.%) were all within 15% and accuracy (%Er) ranged from -5 to 5%. The lower limits of quantification were 0.31 ng mL-1 for all analytes. The extraction recoveries were on average 80.8% for berberine, 67E0% for coptisine, 66.2% for epiberberine, 71.8% for jatrorrhizine and 73E2% for palmatine. The validated method was used to study the pharmacokinetic profile of the five protoberberine alkaloids in rat plasma after oral administration of Coptidis Rhizoma extract.

    Yu Ping Feng San (YPFS), a Chinese herbal decoction, is composed of Astragali Radix (AR; Huangqi), Atractylodis Macrocephalae Rhizoma (AMR; Baizhu) and Saposhnikoviae Radix (SR; Fangfeng) in a weight ratio of 1∶2∶1. Clinically, YPFS has been widely used to regulate immune functions; however, the action mechanism of it is not known. Here, we addressed this issue by providing detail analyses of chemical and biological properties of YPFS. By using rapid resolution liquid chromatography coupled with mass spectrometry, fifteen chemicals deriving from different herbs of YPFS were determined, and which served as a control for the standardization of the herbal extract of YPFS. In general, the amounts of chosen chemical markers were higher in a preparation of YPFS as compared to that of single herb or two-herb compositions. In order to reveal the immune functions of YPFS, the standardized extract was applied onto cultured murine macrophages. The treatment of YPFS stimulated the mRNA and protein expressions of pro-inflammatory cytokines via activation of NF-κB by enhancing IκBα degradation. In contrast, the application of YPFS suppressed the expressions of pro-inflammatory cytokines significantly in the lipopolysaccharide (LPS)-induced chronic inflammation model. In addition, YPFS could up regulate the phagocytic activity in cultured macrophages. These results therefore supported the bi-directional immune-modulatory roles of YPFS in regulating the releases of cytokines from macrophages. PMID:24244327

    Accumulating evidence suggests the anti-inflammatory and anti-obesity activities of Rhizoma Atractylodis Macrocephalae (RAM). Here, we evaluated the anti-obesity impact of unfermented (URAM) versus fermented RAM (FRAM) using both in vitro and in vivo models. Both URAM and FRAM exhibited marked anti-inflammatory, anti-adipogenic, and anti-obesity activities, and modulation of the gut microbial distribution. However, FRAM, compared to URAM, resulted in more efficient suppression of NO production and normalization of transepithelial electrical resistance in LPS-treated RAW 264.7 and HCT 116 cells, respectively. Compared to URAM, FRAM more effectively reduced the adipose tissue weight; ameliorated the serum triglyceride and aspartate transaminase levels; restored the serum HDL level and intestinal epithelial barrier function in the LPS control group. The relative abundance of Bifidobacterium and Akkermansia as well as Bacteriodetes/Firmicutes ratio in the gut of the LPS control group was significantly enhanced by both URAM and FRAM. However, FRAM, but not URAM, resulted in a significant increase in the distribution of Bacteriodetes and Lactobacillus in the gut of the HFD + LPS group. Our results suggest that FRAM with probiotics can exert a greater anti-obesity effect than URAM, which is probably mediated at least in part via regulation of the intestinal microbiota and gut permeability.

    Oxidative stress and oxidative stress mediated β-cell injury are the initial factors of diabetes pathogenesis. Traditional Chinese medicine believes that JiuHuangLian (JHL, Rhizoma Coptidis steamed with rice wine) is an effective agent on diabetes treatment. In present study, we evaluated the antioxidant and lightening β-cell injury of JHL in streptozotocin and a high-glucose/high-fat diet-induced diabetic rats. After 30 days treatment with JHL, glucose tolerance and insulin tolerance of diabetic rats were improved significantly. JHL also could decrease fasting blood glucose and glycosylated hemoglobin levels, increase insulin level and insulin sensitivity index. Moreover, lipid metabolism disorder also adjusted, which manifested as decreased total cholesterol, total glyceride and free fatty acid levels. Meanwhile, a significant increase in superoxide dismutase activity and glutathione content were observed in JHL treated rats, oxidative stress markers such as reactive oxygen species, malondialdehyde and nitric oxide also were decreased by JHL treatment. Furthermore, low expression of caspase-3 were shown in pancreatic immunohistochemistry of JHL treated rats, which exhibited anti-apoptosis effect of β-cell. The histological evidence suggests that JHL effectively rescues the islet atrophied from oxidative stress-mediated β-cell damage. These findings demonstrate the β-cell functional protective nature of JHL by attenuating oxidative stress and inhibiting β-cell damage.

    We observed the influence of different concentrations of Rhizoma paridis total saponins (RPTS) on the apoptosis of colorectal cancer cells and explored the internal mechanism involved. We determined whether RPTS influences the interleukin-6 (IL-6)/Janus kinase (JAK)-signal transducer and activator of transcription-3 (STAT3) apoptosis molecular pathway and looked for colon cancer-related signal transduction pathways or targets inducing apoptosis. We also cultured SW480 colorectal cancer cells using different concentrations of RPTS (10, 20, 40, and 80 μg/ mL), and observed the effect of RPTS on SW480 cell morphology under a fluorescence inverted microscope. We detected serum IL-6 using the polymerase chain reaction and the expression of JAK-STAT3 protein by western blot. After treating SW480 with RPTS and Hoechst 33258 dyeing, we found that the typical apoptosis morphology had changed. Secretion of IL-6 in the serum decreased significantly (P < 0.05), and STAT3 levels were reduced. RPTS can significantly promote apoptosis in SW480 colorectal cancer cells. The mechanism may be that it suppresses the secretion of IL-6 and inhibits the IL-6/JAK-STAT3 protein signaling pathway. PMID:26125778

    Preclinical Research Rhizoma Coptidis (RC), the root of Coptis chinensis Franch, a species in the genus Coptis (family Ranunculaceae), has been commonly prescribed for the treatment of diabetes in Chinese traditional herbal medicine applications. The present study is focused on the assessment of the antihyperglycemia and antidiabetic hyperlipidemia effect of five protoberberine alkaloids, berberine (BBR), coptisine (COP), palmatine (PAL), epiberberine (EPI), and jatrorrhizine (JAT), separated from R. Coptidis in hepatocellular carcinoma HepG2 cells and diabetic KK-Ay mice. Protoberberine alkaloids are effective in modulating hyperglycemia and hyperlipidemia. After adding BBR and COP to culture medium, glucose consumption of HepG2 cells was increased. In KK-Ay mice assays, suppressed fasting blood glucose level and ameliorated glucose tolerance were observed after BBR/COP administration. After treated with berberine and coptisine, in the same dose of 5 µg/mL, the glucose consumption of HepG2 cells were promoted and, respectively, reached 96.1% and 17.6%. Body weight, food consumption, water intake, and urinary output of KK-Ay mice were reduced after treated with EPI. Serum total cholesterol and triglyceride of mice were decreased after treated with palmatine and jatrorrhizine. Serum high-density lipoprotein cholesterol of mice was increased after palmatine, jatrorrhizine, and berberine administrated. Moreover, hepatomegaly was attenuated in JTR-treated mice. Suggested that these protoberberine alkaloids from R. Coptidis have potential curative effect for diabetes. Drug Dev Res 77 : 163-170, 2016.   © 2016 Wiley Periodicals, Inc. PMID:27045983

    Rhizoma Alpinia officinarum (Hance) Farw, Zingiberaceae (AO), a ginger family herb exhibiting stimulant and a carminative bioactivity, is widely used in European and Asian countries as spicy condiment and medicinal uses. Allyl isothiocyanate (AITC) is the main pungent taste of native Wasabi (Wasabia japonica). The cytotoxicity of AITC has been implicated in thymus, adrenals, and white blood cells. Considering food safety, apparently a safer substitute for wasabi is worthy commercialized. Previously, we found AO crude paste to be rather feasible for use as a "Wasabi-substitute" in fresh meat and cold salads. A process linking cold ethyl acetate (EtAc) extraction with silica gel adsorption and reversed phase high-performance liquid chromatography (RP-HPLC) (mobile phase, 75% methanol) was used to isolate galangal acetate, the Wasabi-like taste constituent. AO contained abundant galangal acetate (3.84 ± 0.07%) compared to A. galangal (0.57 ± 0.16%), and as already confirmed by thin layer chromatography (TLC), gas chromatography (GC)/mass spectrometry (MS)/MS and Nuclear Magnetic Resonance Spectroscopy (NMR), galangal acetate was particularly thermally labile. The steam distilled essential oil (SDEO) of AO (0.14% on wet basis) contained 80 compounds (number of component, %): monoterpene hydrocarbon (21, 13.83%); oxygenated monoterpene (17, 27.08%); sesquiterpene hydrocarbon (20, 31.03%), and oxygenated sesquiterpene (20, 21.85%), respectively. However, no spicy wasabi-like constituent remained in SDEO. Alternatively, n-hexane, EtAc, and methanol extracts of AO all showed potent DPPH- and superoxide anion-scavenging activity. Conclusively, SDEO although contains 80 volatiles, galangal acetate is absent due to thermal instability. Galangal acetate exhibits pleasant "Wasabi-like taste" for which we have successively developed an integrated process for mass production. PMID:27166764

    Podocyte injury contributes to renal damage and, eventually, to the occurrence of proteinuria in diabetic nephropathy. The aim of the present study was to investigate the effect of an ethanol extract from Rhizoma Polygonum cuspidatum (P. cuspidatum) on proteinuria and podocyte injury, and elucidate the underlying mechanism for streptozotocin (STZ)‑induced diabetic nephropathy. The protective effects of P. cuspidatum extract (PCE) on renal podocytes in STZ‑induced diabetic rats were also investigated. PCE (100 or 350 mg/kg/day) was administered to STZ‑induced diabetic rats for 16 weeks, and blood glucose levels, body weight and proteinuria were measured. A double labeling technique with the terminal deoxynucleotidyl transferase dUTP nick end labeling assay was performed and synaptopodin expression was observed. In addition, cleaved caspase‑3, methylglyoxal (MGO) and 8‑hydroxydeoxyguanosine (8‑OHdG) expression levels were measured. STZ‑induced diabetic rats developed hyperglycemia and proteinuria. Increased apoptosis of the podocytes and increased cleaved caspase‑3, MGO and 8‑OHdG expression levels, as well as decreased synaptopodin expression were detected in the glomeruli of STZ‑induced diabetic rats. However, treatment with PCE for 16 weeks restored protein levels to normal, and reduced podocyte loss and apoptosis. Levels of caspase‑3 and MGO expression, as well as oxidative stress were ameliorated by PCE treatment. In addition, emodin, a biologically active ingredient of PCE, exerted an MGO scavenging effect and inhibited MGO‑derived advanced glycation end‑product formation. These findings indicate that PCE may be administered to prevent proteinuria and podocyte loss in STZ‑induced diabetic rats partly by inhibiting podocyte apoptosis and cleaved caspase‑3 expression, and by restoring the balance of oxidative stress and MGO expression.

We found a significant results that CR+GR extracted using ethanol stimulated the growth of MCF-7 cells in estrogen activity and was attenuated in lipid deposition of HepG2 cells treated with MβCD compared to CR and GR treatments each. To investigate the situation, an experimental menopause rat model with dyslipidemia was induced by surgical bilateral ovariectomy (OVX) and high fat high cholesterol (HFHC) diet in female rats. OVX rats fed HFHC (OVX-HFHC) showed a shift in weight gain, elevated serum cholesterol, altered liver enzymatic parameters and enhanced liver injury compared to the NC and HFHC groups. However, administration of CR+GR, in particular 200 or 450 mg/kg/day, inhibited the increase in body weight gain and lipid metabolic disturbances, lowering total cholesterol (TC), triglycerides (TG) and low density lipoprotein cholesterol (LDL-C) compared to the OVX-HFHC group. Furthermore, CR+GR (200 or 450 mg/kg/day) ameliorated the serum levels of the liver enzymes aspartate aminotransferase (AST) and alanine transaminase (ALT) compared to the OVX-HFHC group. Moreover, CR+GR (200 or 450 mg/kg/day) attenuated not only hepatic steatosis but also larger adipocytes. Our study demonstrated that combined treatment with CR and GR attenuated metabolic complications induced by OVX and HFHC diet, suggesting that this effect may regulate and prevent the acceleration of cardiovascular disease (CVD) after menopause.

    Alismatis Rhizoma (AMR) is a well-known natural medicine with a long history in Chinese medicine and has been commonly used for treating a wide range of ailments related to dysuria, edema, nephropathy, hyperlipidaemia, diabetes, inflammation as well as tumors in clinical applications. Most beneficial effects of AMR are attributed to the presence of protostane terpenoids, the major active ingredients of Alismatis Rhizoma (AMR). In this study, a systematic high performance liquid chromatography/diode-array detector/quadrupole-time-of-flight mass spectrometry (HPLC-DAD-Q-TOF MS) and ultra-performance liquid chromatography/triple quadrupole mass spectrometry (UPLC-QqQ MS) method was developed for qualitative and quantitative analyses of the major AMR triterpenoids. First, a total of 25 triterpenoid components, including 24 known compounds and one new compound were identified by comparison with UV spectra, molecular ions and fragmentation behaviors of reference standards or the literature. Second, an efficient method was established for the rapid simultaneous determination of 14 representative triterpenoids by UPLC-QqQ MS. Forty-three batches of AMR were analyzed with linearity (r, 0.9980-0.9999), intra-day precision (RSD, 1.18%-3.79%), inter-day precision (RSD, 1.53%-3.96%), stability (RSD, 1.32%-3.97%), repeatability (RSD, 2.21%-4.25%), and recovery (98.11%-103.8%). These results indicated that new approaches combining HPLC-DAD-Q-TOF MS and UPLC-QqQ MS are applicable in the qualitative and quantitative analysis of AMR.

    The analysis of trace constituents in herbal medicines has always been a challenge due to complex matrices and structural diversities. In this work, a pH-sensitive solid phase extraction (SPE) procedure capable of enriching trace polyphenols in Bistort Rhizoma (BR) was proposed and preliminary chemical characterization was accomplished by high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (HPLC-QTOF MS). A weak anion-exchange SPE column packed with divinylbenzene/vinylpyrrolidone bonding quaternary amine group was employed for anionic extraction, and the target fraction was obtained by eluting with acidic methanol (apparent pH 1.9). On the other hand, the MS/MS fragmentation rules of four reference polyphenols in negative ion mode were outlined. Using these rules, a total of 31 polyphenols including 20 benzoyl derivatives and 11 caffeoyl derivatives were screened out from BR extract, of which 26 trace members were found for the first time in this herb. Those findings demonstrated that the anion-exchange SPE could enhance the detection capability and selectivity for plant polyphenols in the LC-MS analysis and the strategy for deducing structures could be applied for analysis of polyphenols in BR and other herbal medicines.

    This study was performed in order to investigate the antiobese effects of the ethanolic extract of Veratri Nigri Rhizoma et Radix (VN), a herb with limited usage, due to its toxicology. An HPLC analysis identified jervine as a constituent of VN. By an Oil Red O assay and a Real-Time RT-PCR assay, VN showed higher antiadipogenic effects than jervine. In high-fat diet- (HFD-) induced obese C57BL/6J mice, VN administration suppressed body weight gain. The levels of peroxisome proliferator-activated receptor gamma (PPARγ), CCAAT-enhancer-binding protein alpha (C/EBPα), adipocyte fatty-acid-binding protein (aP2), adiponectin, resistin, and LIPIN1 were suppressed by VN, while SIRT1 was upregulated. Furthermore, VN activated phosphorylation of the liver kinase B1- (LKB1-) AMP-activated protein kinase alpha- (AMPKα-) acetyl CoA carboxylase (ACC) axis. Further investigation of cotreatment of VN with the AMPK agonist AICAR or AMPK inhibitor Compound C showed that VN can activate the phosphorylation of AMPKα in compensation to the inhibition of Compound C. In conclusion, VN shows antiobesity effects in HFD-induced obese C57BL/6J mice. In 3T3-L1 adipocytes, VN has antiadipogenic features, which is due to activating the LKB1-AMPKα-ACC axis. These results suggest that VN has a potential benefit in preventing obesity. PMID:27143989

    In Japan, there are about 250 Yakushi Buddha (i.e., Buddha of Healing) statues in Buddhist temples. They are listed as Important Cultural Properties and 14 of them are National Treasures. Belief in Yakushi Buddha was especially prevalent from the 7th to the 13th centuries in Japan. The oldest wooden Yakushi Buddha statue is in Horin-ji Temple in Nara. Among the approximately 250 Yakushi Buddha statues, about 200 have medicinal containers-or rarely, a bowl-in the palm of the left hand. However, these medicinal containers are wooden blocks. Very recently, it was found that the Yakushi Buddha statue in the Suho-Kokubun-ji Temple in Yamaguchi Prefecture, Japan has a medicinal container in the palm of his left hand, in which an offering (i.e., 220 g of materials) was found. The date on the reverse side of the lid places the offering at October 12, 1699. The offering is composed of five cereals (rice, barley, wheat, soybean and azuki bean), five medicinal plants (Acori graminei, Acori calami, Ginseng, Flos caryophylli and Lignum santali albi) and six minerals (rock crystals, purple and blue lead glass, CaCO3 particles, and silver and golden foils). Recently, the pharmacy educational program was extended from four to six years in order to meet clinical pharmacy requirements for patients. From studying the Buddha of Healing and its medicinal container described above, the author suggests that, in addition to pharmaceutical bioscience, philosophical concept be studied as part of the history of pharmacy in the future.

    Rhizoma coptidis (R.C.), a widely used traditional Chinese medicine, has been used for centuries in the treatment of hypertension, inflammation, dysentery and liver diseases, etc. Wine-processing is a specialized technology by sautéing crude herbal medicine using Chinese rice wine. This paper was designed to establish a simultaneous quantitative method of ten alkaloids (berberine, coptisine, palmatine, jatrorrhizine, epiberberine, magnoflorine, columbamine, noroxyhydrastinine, oxyberberine and 8-oxocoptisine) in rat plasma. Furthermore, the pharmacokinetics of those alkaloids after administration of crude and wine-processed R.C. aqueous extracts was compared. As a result, a ultra high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UHPLC-ESI-MS/MS) method was developed and validated for the first time. Chromatographic separation was achieved on a C18 column using gradient elution with the mobile phase consisting of acetonitrile and water (containing 0.2% formic acid) at a flow rate of 0.2 ml/min. The validated method showed good linearity over a wide concentration range (r>0.99), and lower limits of quantification less than 5.46 ng/ml for the each analyte. The intra- and inter-day assay variability was below 9.9% and 10.5% for all analytes, respectively. The extraction recovery of those alkaloids and I.S. ranged from 65.3% to 90.7%. The validated method has been successfully applied to pharmacokinetic comparison after administration of crude and wine-processed R.C. aqueous extracts. Pharmacokinetic comparative study showed that Cmax of coptisine and 8-oxocoptisine and AUC0-t of coptisine, palmatine and 8-oxocoptisine were increased significantly (p<0.05) after wine-processing, while other compounds didn't show significant difference, which suggested that wine-processing exerted limited effects on the absorption of alkaloids. These results might be helpful for R.C.' clinical reasonable application and further studies on its wine

    The membrane enrichment process of traditional Chinese medicine volatile oil is environmental friendly and practical, with a good application prospect. In this article, oil-bearing solutions of eight traditional Chinese medicines, namely Caryophylli Flos, Schizonepetae Herba, Eupatorii Herb, Acori Talarinowii Rhizoma, Magnoliae Flos, Chrysanthemum indicum, Cyperi Rhizoma and Citri Reticulatae Pericarpium Viride, were taken as the experimental system. Under unified conditions (membrane: PVDF-14W, temperature: 40 degreeC, pressure: 0. 1 MPa, membrane surface speed: 150 r min- 1), trans-membrane was conducted for above eight oil-bearing solutions to explore the effect of their oil-bearing solution environment on system flux and oil recovery rate. The results showed that systems with smaller pH had a lower flux, without significant effect on oil recovery rate. Greater differences between the surface tension of solutions and that of pure water contributed to a lower oil recovery rate. The conductivity had no notable effect on membrane enrichment process. Systems with high turbidity had a lower flux, without remarkable effect on oil recovery rat. Heavy oils showed lower flux than light ones, but with a slightly higher oil recovery rat. Systems with higher viscosity had a lower flux than those with lower viscosity. Except for Magnoliae Flos volatile oil, all of the remaining volatile oils showed a much higher oil recovery rat than systems with high viscosity. The above results could provide data support and theoretical basis for the industrialization of membrane enrichment volatile oil technology. PMID:24422391

    Kai-Xin-San (KXS), a Chinese herbal decoction for anti-depression, is a combination of paired-herbs, i.e. Ginseng Radix et Rhizoma (GR)-Polygalae Radix (PR) and Acori Tatarinowii Rhizoma (ATR)-Poria (PO). The make-up of the paired-herbs has been commonly revised according to syndrome differentiation and treatment variation of individual. Currently, an optimized KXS (KXS2012) was prepared by functional screening different combination of GR-PR and ATR-PO. The aim of this study was to verify the effect and underlying mechanism of KXS2012 against depression in chronic mild stress (CMS)-induced depressive rats and in primary cultures of neurons and astrocytes. In rat model, the CMS-induced depressive symptoms were markedly alleviated by the treatment with KXS2012. The CMS-suppressed neurotransmitter amounts were restored in the presence of KXS2012. And the expressions of neurotropic factors and its corresponding receptors were increased under KXS2012 administration. In cultured neurons, application of KXS2012 could promote neurogenesis by inducing the expression of synaptotagmin and dendritic spine density. Moreover, application of KXS2012 in cultured astrocytes, or in H2O2-stressed astrocytes, induced the expressions of neurotrophic factors: the increase might be associated with the modification of Erk1/2 and CREB phosphorylation. Our current results fully support the therapeutic efficacy of KXS2012 against depression in cell and animal models. PMID:27444820

    Adulterant herbal materials are a threat to consumer safety. In this study, we used DNA barcoding to investigate the proportions and varieties of adulterant species in traditional Chinese medicine (TCM) markets. We used a DNA barcode database of TCM (TCMD) that was established by our group to investigate 1436 samples representing 295 medicinal species from 7 primary TCM markets in China. The results indicate that ITS2 barcodes could be generated for most of the samples (87.7%) using a standard protocol. Of the 1260 samples, approximately 4.2% were identified as adulterants. The adulterant focused on medicinal species such as Ginseng Radix et Rhizoma (Renshen), Radix Rubi Parvifolii (Maomeigen), Dalbergiae odoriferae Lignum (Jiangxiang), Acori Tatarinowii Rhizoma (Shichangpu), Inulae Flos (Xuanfuhua), Lonicerae Japonicae Flos (Jinyinhua), Acanthopanacis Cortex (Wujiapi) and Bupleuri Radix (Chaihu). The survey revealed that adulterant species are present in the Chinese market, and these adulterants pose a risk to consumer health. Thus, regulatory measures should be adopted immediately. We suggest that a traceable platform based on DNA barcode sequences be established for TCM market supervision. PMID:26740340

    Shancigu (Rhizome Pleionis) was first recorded in the Ben cao shiyi (Supplements to Chinese Materia Medica). The source of the strain of this medicinal was unclear because of its too simple description in the medical books in the Tang and Song dynasties. Its original plant could be Cremastra appendiculata (D.Don) Makino, Tulipa edulis (Miq.) Baker and so on. The original plant of Shanciguwas Tulipaedulis since the Ming dynasty to the Republican period. The name of "Guangcigu" began to appear in the Republican period because of the changes of its processing method. The original plants evolved into Cremastra appendiculata, Pleione bulbocodioides (Franch.) Rolfe and Pleione yunnanensis Rolfe, with Tulipa edulisas the original plant of Guangcigu (Bulbus of Tulipasedulis). It is found that only the Tulipaedulis is the unequivocal origin with the longest medicinal history through sorting out of the original plants of Shancigu. Hence, it is suggested that Tulipa edulis should be recovered as the original strain of Shancigu.

    Alzheimer’s disease (AD) is a progressive neurodegenerative disease that causes substantial public health care burdens. Intensive efforts have been made to find effective and safe disease-modifying treatment and symptomatic intervention alternatives against AD. Smart Soup (SS), a Chinese medicine formula composed of Rhizoma Acori Tatarinowii (AT), Poria cum Radix Pini (PRP) and Radix Polygalae (RP), is a typical prescription against memory deficits. Here, we assessed the efficacy of SS against AD. Oral administration of SS ameliorated the cognitive impairment of AD transgenic mice, with reduced Aβ levels, retarded Aβ amyloidosis and reduced Aβ-induced gliosis and neuronal loss in the brains of AD mice. Consistently, SS treatment reduced amyloid-related locomotor dysfunctions and premature death of AD transgenic Drosophila. Mechanistic studies showed that RP reduced Aβ generation, whereas AT and PRP exerted neuroprotective effects against Aβ. Taken together, our study indicates that SS could be effective against AD, providing a practical therapeutic strategy against the disease. PMID:25386946

    Aim β-asarone, an active component of Acori graminei rhizome, has been reported to have neuroprotective effects in Alzheimer’s disease. As the underlying mechanism is not known, we investigated the neuroprotective effects of β-asarone in an APP/PS1 double transgenic mouse model and in NG108 cells. Materials and methods APPswe/PS1dE9 double transgenic male mice were randomly assigned to a model group, β-asarone treatment groups (21.2, 42.4, or 84.8 mg/kg/d), or donepezil treatment group (2 mg/kg/d). Donepezil treatment was a positive control, and background- and age-matched wild-type B6 mice were an external control group. β-asarone (95.6% purity) was dissolved in 0.8% Tween 80 and administered by gavage once daily for 2.5 months. Control and model animals received an equal volume of vehicle. After 2.5 months of treatment, behavior of all animals was evaluated in a Morris water maze. Expression of synaptophysin (SYP) and glutamatergic receptor 1 (G1uR1) in the hippocampus and cortex of the double transgenic mice was assayed by Western blotting. The antagonistic effects of β-asarone against amyloid-β peptide (Aβ) were investigated in vitro in the NG108-15 cell line. After 24 hours of incubation, cells were treated with 10 μm Aβ with or without β-asarone at different concentrations (6.25, 12.5, or 25 μM) for an additional 36 hours. The cytotoxicity of β-asarone was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay of cell viability, and cell morphology was evaluated by bright-field microscopy after 24 hours of treatment. The expression of SYP and GluR1 in cells was detected by Western blot assay in the hippocampus and brain cortex tissues of mice. Results β-asarone at a high dose reduced escape latency and upregulated SYP and GluR1 expression at both medium and high doses. Cell morphology evaluation showed that β-asarone treatment did not result in obvious cell surface spots and cytoplasmic granularity. β-asarone had a

First, polyamide T60-100 was employed to fractionalize the crude extracts of Anemarrhenae Rhizome. Macroporous resin HPD400 was subsequently used to purify the xanthones and steroidal saponins. Under the optimized conditions, 2.31 g of NMF, 4.10 g of MF, 12.87 g of TS B-II, and 2.78 g of TS A-III were prepared from 1 kg of crude materials, and their purities were 90.0, 92.15, 90.8, and 92.61%, respectively. The results of this study indicate that the combined column chromatography with polyamide and macroporous adsorption resins can be referenced as a green and efficient alternative for large-scale purification of bioactive ingredients from herbal raw materials.

    Excessive production of inflammatory mediators such as nitric oxide (NO), prostaglandin E(2) (PGE2), and proinflammatory cytokines, including tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) from activated microglia contributes to uncontrolled inflammation in neurodegenerative diseases. It seems possible that treatment with anti-inflammatory agents, including plants used in Oriental medicine, might delay the progression of neurodegeneration through the inhibition of microglial activation. The present study is focused on the inhibitory effect of the rhizome hexane fraction extract of Zingiber officinale Roscoe (ginger hexan extract; GHE) on the production of inflammatory mediators such as NO, PGE(2), and proinflammatory cytokines in lipopolysaccharide (LPS)-stimulated BV-2 cells, a mouse microglial cell line. GHE significantly inhibited the excessive production of NO, PGE(2), TNF-alpha, and IL-1beta in LPS-stimulated BV2 cells. In addition, GHE attenuated the mRNA expressions and protein levels of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and proinflammatory cytokines. The molecular mechanisms that underlie GHE-mediated attenuation are related to the inhibition of the phosphorylation of three mitogen-activated protein kinases (MAPKs), extracellular signal-regulated kinases 1 and 2 (ERK1/2), p38 MAPK, and c-Jun N-terminal kinase (JNK), and the activation of nuclear factor-kappaB (NF-kappaB). Our results indicate that GHE exhibits anti-inflammatory properties by suppressing the transcription of inflammatory mediator genes through the MAPK and NF-kappaB signaling pathways. The anti-inflammatory properties of GHE may make it useful as a therapeutic candidate for the treatment of human neurodegenerative diseases. PMID:19233241

    Belamcandae chinensis rhizoma, is a rhizome of Iris domestica (syn. Belamcanda chinensis). Under the Chinese name she gan, it is extensively used in Traditional Chinese Medicine and other East Asian phytotherapy systems. Recently, the monograph of Belamcandae chinensis rhizoma has been included in the European Pharmacopeia. This review provides a comprehensive summary and systematizes the literature data on ethnobotanical uses, chemical constituents and biological effects of Belamcandae chinensis rhizoma and its components. The main group of phytochemicals identified in the dried rhizoma are polyphenols such as isoflavones, xanthone glycosides, stilbenes, simple phenols and quinones. Another characteristic class of substances are triterpenopid iridals. The most typical traditional usage of Belamcandae chinensis rhizoma is for healing respiratory diseases but most of pharmacological research so far has been focused on isoflavones and their estrogenic properties. In pharmacological research, it has been mainly considered as a source of tectorigenin--a phytoestrogene with therapeutic potential in hormone-dependent cancer. The most active isoflavones are tectoridin, tectorigenin and irigenin. The available literature indicates that Belamcandae chinensis rhizoma can prevent excessive oxidation of biomolecules based on various antioxidant mechanisms: transition metal ions reduction, inhibition of lipid peroxidation, free radicals scavenging. The other biological activities proven by a number of in vitro studies include: antimutagenic,anti-inflammatory, anti-angiogenic, hypoglycemic. In conclusion, the knowledge about Belamcandae chinensis rhizoma has been growing rapidly in the recent years,but there are still significant gaps in our understanding of its bioactivity, therapeutic value, and roles played by each of the numerous phytochemicals.

    Plant growth retardant as one of plant growth regulator can inhibit the cell division, elongation and growth rate in shoot apical meristem (SAM), which can be reversed by gibberellin regulate the product of photosynthesis transfer to the root and rhizome part. As commonly used plant growth retardant, paclobutrazol, uniconazole, chlorocholine chloride, mepiquat chloride, choline chloride and daminozide are used to promote the growth of root and rhizome, call as "zhuanggenling", "pengdasu", "pengdaji" etc. Single or recombination of plant growth regulator is registered as pesticide, and called as pesticide "zhuanggenling" in this paper. Growth regulator which registered as a foliar fertilizer or fertilization was called agricultural fertilizer "zhuanggenling" in this paper. The author investigate the usage of "zhuanggenling" in the root and rhizome of medicinal plants cultivation from 2012 to 2014 in Sichuan province, Huangyuan town, Mianyang (Ophiopogonis Radix); Pengzhou Aoping town (Chuanxiong Rhizoma); Pengshan Xiejia town (Alismatis Rhizoma); Jiangyou Taiping town and Zhangming town (Aconiti Lateralis Radix Praeparata); Yunnan Wenshan (Notoginseng Radix et Rhizoma); Henan province, Wuzhidafeng Town (Rehmanniae Radix, Achyranthis Bidentatae Radix, Dioscoreae Rhizoma); Gansu Min county (Codonopsis Radix, Angelicae Sinensis Radix); Gansu Li county (Rhei Radix et Rhizoma). The result showed that "zhuanggenling" were applied in the most medicinal plant cultivation except Rhei Radix et Rhizoma. It has been applied widespreadly in Ophiopogonis Radix, Alismatis Rhizoma, Achyranthis Bidentatae Radix, Codonopsis Radix; Rehmanniae Radix, commonly in Angelicae Sinensis Radix application, and occasionally in Chuanxiong Rhizoma, Aconiti Lateralis Radix Praeparata, Notoginseng Radix et Rhizoma and Dioscoreae Rhizoma. In 53 collected sample from plantation areas, fifteen (28%) were pesticide "zhuanggenling", thirty-eight (72%) were pesticide "zhuanggenling". UPLC analysis

    Pulse analysis is a powerful method in Chinese medicine. We suggest that the effect of herbal medicine is to redistribute the blood to organs and meridians. In this report, by injecting extracts into rats and then analyzing the blood pressure wave measured at the caudate arteries, we studied eight important spleen meridian related herbs: They were Semen Lablab, Fructus Amomi Globosi, Rhizoma Atractylodis Macrocephalae, Rhizoma Atractylodis, Tuber Pinelliae, Radix Codonopsitis, Pericarpium Aurantii and Rhizoma Polygonati. All eight herbs increased the intensity of the 3rd harmonic (C3) of the pressure pulse which is correlated to the spleen and spleen meridian, as described in traditional Chinese medical literature. All of them also increased the 2nd harmonic (which is correlated to the kidney and the kidney meridian) as well as decreased the heart load (DC term of pressure wave, C0). Tuber Pinelliae, Radix Codonopsitis, Pericarpium Aurantii and Rhizoma Polygonati decreased the 1st harmonic (correlated to the liver meridian) significantly, while Rhizoma Atractylodis Macrocephalae only decreased C1 slightly. Except for Semen Lablab, all the others decreased the intensity of the 5th (stomach meridian) and the 7th harmonics. The effects of kidney herbs: Cortex Eucommiae and Radix Achyranthis were also shown for comparison.

    Rhei Radix et Rhizoma was one of the commonly used traditional Chinese medicines, and the compatibility of Rhei Radix et Rhizoma and Aconiti Lateralis Radix Praeparata was the basic herb pair applied in many Chinese traditional prescription. Rhubarb anthraquinones were the main bioactive materials of Rhei Radix et Rhizoma. To elucidate the compatibility of Rhei Radix et Rhizoma and Aconiti Lateralis Radix Praeparata, the pharmacokinetics of rhubarb anthraquinones as the main marker constituents were investigated. In the present study, pharmacokinetic differences of rhubarb anthraquinones were detected after oral administration of extract of Rheum palmatum L. and compatibility with Aconitum carmichaelii Debx. After oral administration, no difference of peak time can be found for anthraquinones between rhubarb group and compatibility group. But Cmax and area under the curve of aloe-emodin, emodin and chrysophanol in compatibility group were significantly higher than that in rhubarb group. Although the Cmax of rhein in compatibility group was much lower than that in rhubarb group, the area under the curve value was similar in two groups. The clearance and t1/2 of rhubarb anthraquinone were also changed after compatibility. The change of pharmacokinetics characteristics of rhubarb anthraquinone after compatibility may be caused by the drug-drug interaction medicated by chemical reaction and cytochromes P450.

    Rhizoma Dioscoreae Nipponicae, from Discorea nipponica, is a widely used traditional Chinese herb. It is used to treat arthroncus, arthrodynia, and arthritis. Hyperuricemia is an important foundation of gouty arthritis. The current study was aimed at investigating whether the effects of total saponins from Rhizoma Dioscoreae Nipponicae on hyperuricemia were due to renal organic ion transporters in potassium oxonate-induced hyperuricemia mice. Hyperplasia of synovial cells prepared from Wistar rats was induced by IL-1β (1 × 10(4) µg/mL). MTT was used and to screen active components in the inhibition of hyperplasia by total saponins from Rhizoma Dioscoreae Nipponica, individual pure compounds, and different combinations of these compounds. Sixty Kun Ming mice were randomly divided into six groups: normal, model, allopurinol (40 mg/kg), and three total saponins groups receiving dose (600 mg/kg), middle (300 mg/kg), and low doses (60 mg/kg). Hyperuricemic mice were induced with potassium oxonate (300 mg/kg) intragastrically. The total saponins were given six days and the positive drug allopurinol was given one day before inducing hyperuricemia. The serum and urine levels of uric acid and creatinine and the fractional excretion of uric acid were measured in normal and hyperuricemic mice treated with Rhizoma Dioscoreae Nipponicae and allopurinol. The mRNA and protein levels of the mouse urate transporter 1, glucose transporter 9, organic anion transporter 1, and organic anion transporter 3 were analyzed by real-time-PCR and Western blotting methods, respectively. Total saponins from Rhizoma Dioscoreae Nipponicae could effectively reverse potassium oxonate-induced alterations in renal mouse urate transporter 1, glucose transporter 9, organic anion transporter 1, and organic anion transporter 3 mRNA and protein levels, resulting in enhancement of renal urate excretion in mice. These findings suggested that the total saponins from Rhizoma Dioscoreae

    Rhizoma Polygoni Cuspidati, a Chinese herbal medicine, has been widely used in traditional Chinese medicine for a long time. Polydatin, one of the major active ingredients in Rhizoma Polygoni Cuspidati, has been recently shown to possess extensive cardiovascular pharmacological activities. In present study, we examined the effects of Polydatin on the formation of peritoneal macrophage-derived foam cells in Apolipoprotein E gene knockout mice (ApoE−/−) and explored the potential underlying mechanisms. Peritoneal macrophages were collected from ApoE−/− mice and cultured in vitro. These cells sequentially were divided into four groups: Control group, Model group, Lovastatin group, and Polydatin group. Our results demonstrated that Polydatin significantly inhibits the formation of foam cells derived from peritoneal macrophages. Further studies indicated that Polydatin regulates the metabolism of intracellular lipid and possesses anti-inflammatory effects, which may be regulated through the PPAR-γ signaling pathways.

    Rhizoma Atractylodes macrocephala, Radix Isatidis, Coptis chinensis and Flos Genkwa are common herbal remedies used by pregnant woman in China. In this study, their potential embryotoxicity was assessed using the embryonic stem cell test (EST) and a prediction model. The potential embryotoxicity of the herbs was based on three endpoints: the concentrations of the compounds that inhibited the proliferation of 50% of embryonic stem cells (ESCs) (IC50ES), the concentrations that inhibited 50% of 3T3 cells (IC503T3), and the concentrations that inhibited the differentiation of 50% of ESCs (ID50ES). The results revealed that Rhizoma Atractylodes macrocephala and Radix Isatidis are non-embryotoxic compounds. Coptis chinensis extracts appeared to demonstrated weak embryotoxicity, and Flos Genkwa exhibited strong embryotoxicity. These results may be useful in guiding the clinical use of these herbs and in expanding the application of the EST to the field of traditional Chinese medicine.

    The allegation of "Glycyrrhiza antagonistic to Sargassum, Euphorbia Pekinensis, Kansui, and Genkwa", being one of the hypotheses of "18 antagonisms" in TCM pharmacology, is referring to the antagonistic action among the Radix et Rhizoma Glycyrrhiza and Radix Euphorbiae Kansui, Radix Euphorbiae Pekinensis, Flos Genkwa, and Sargassum when compounded together in a single recipe. By reviewing its history concerted with modern knowledge, it can be found that the theory of "seven emotions" was originated from Shennong's Classic of Materia Medica; while the Variorum of the Classic of Materia Medica firstly and definitely records that Radix et Rhizoma Glycyrrhizae is forbidden to be used with Radix Kansui, Flos Genkwa, Radix Euphorbiae Pekinensis, Sargassum together in a single formula. It was summarized into a Chinese poetic sentence as above-mentioned later. In the works of later ages, including Chinese Pharmacopoeia, A Great Dictionary of Chinese Materia Medica, and China's Herbology, etc., all enhance the understanding of the prohibited combination of Radix et Rhizoma Glycyrrhizae and its incompatible herbs. Nevertheless, there are discrepancies between the results of modern experimental and clinical studies on this problem, which, needless to say, should be resolved by further investigations.

    The objective of this study was to develop an effective strategy for screening and identifying mycotoxins in herbal medicine (HM). Here, Imperatae Rhizoma, a commonly used Chinese herb, was selected as a model HM. A crude drug contaminated with fungi was analyzed by comparing with uncontaminated ones. Ultra-performance LC coupled to tandem quadrupole TOF-MS (UPLC-Q-TOF-MS) with collision energy function was applied to analyze different samples from Imperatae Rhizoma. Then, MarkerLynx(TM) software was employed to screen the excess components in analytes, compared with control samples, and those selected markers were likely to be the metabolites of fungi. Furthermore, each of the accurate masses of the markers obtained from MarkerLynx(TM) was then searched in a mycotoxins/fungal metabolites database established in advance. The molecular formulas with relative mass error between the measured and theoretical mass within 5 ppm were chosen and then applied to MassFragment(TM) analysis for further confirmation of their structures. With the use of this approach, five mycotoxins that have never been reported in HM were identified in contaminated Imperatae Rhizoma. The results demonstrate the potential of UPLC-Q-TOF-MS coupled with the MarkerLynx(TM) software and MassFragment(TM) tool as an efficient and convenient method to screen and identify mycotoxins in herbal materials and aid in the quality control of HM.

    A sensitive, simple, and validated high-performance liquid chromatography with diode array detection and mass spectrometry detection method was developed for three ginger-based traditional Chinese herbal drugs, Zingiberis Rhizoma, Zingiberis Rhizome Preparatum, and Zingiberis Rhizome Carbonisata. Chemometrics methods, such as principal component analysis, hierarchical cluster analysis, and analysis of variance, were also employed in the data analysis. The results clearly revealed significant differences among Zingiberis Rhizoma, Zingiberis Rhizome Preparatum, and Zingiberis Rhizome Carbonisata, indicating variations in their chemical compositions during the processing, which may elucidate the relationship of the thermal treatment with the change of the constituents and interpret their different clinical uses. Furthermore, the sample consistency of Zingiberis Rhizoma, Zingiberis Rhizome Preparatum, and Zingiberis Rhizome Carbonisata can also be visualized by high-performance liquid chromatography with diode array detection and mass spectrometry analysis followed by principal component analysis/hierarchical cluster analysis. The comprehensive strategy of liquid chromatography with mass spectrometry analysis coupled with chemometrics should be useful in quality assurance for ginger-based herbal drugs and other herbal medicines.

    The liver is intimately connected to inflammation, which is the innate defense system of the body for removing harmful stimuli and participates in the hepatic wound-healing response. Sustained inflammation and the corresponding regenerative wound-healing response can induce the development of fibrosis, cirrhosis and eventually hepatocellular carcinoma. Oxidative stress is associated with the activation of inflammatory pathways, while chronic inflammation is found associated with some human cancers. Inflammation and cancer may be connected by the effect of the inflammation-fibrosis-cancer (IFC) axis. Chinese medicinal herbs display abilities in protecting the liver compared to conventional therapies, as many herbal medicines have been shown as effective anti-inflammatory and anti-oxidative agents. We review the relationship between oxidative stress and inflammation, the development of hepatic diseases, and the hepatoprotective effects of Chinese medicinal herbs via anti-inflammatory and anti-oxidative mechanisms. Moreover, several Chinese medicinal herbs and composite formulae, which have been commonly used for preventing and treating hepatic diseases, including Andrographis Herba, Glycyrrhizae Radix et Rhizoma, Ginseng Radix et Rhizoma, Lycii Fructus, Coptidis Rhizoma, curcumin, xiao-cha-hu-tang and shi-quan-da-bu-tang, were selected for reviewing their hepatoprotective effects with focus on their anti-oxidative and ant-inflammatory activities. This review aims to provide new insight into how Chinese medicinal herbs work in therapeutic strategies for liver diseases.

    The improving effects of various components of Toki-Shakuyaku-San (TSS) and fractions isolated from Angelica acutiloba Radix (Toki) on scopolamine-induced spatial memory impairment were investigated in eight-armed radial maze. The scopolamine-induced memory impairment was characterized by prominent increase of error choices in addition to decreased correct choices. Toki, Cnidium officinale Rhizoma (Senkyu), Poria cocos Hoelen (Bukuryo), Alisma orientale Rhizoma (Takusha), and Atractylodes lancea Rhizoma (Sojutsu) increased the correct choices, while only the Toki, Sojutsu, and Takusha decreased the error choices. No effect was produced by Paeonia lactiflora Radix (Shakuyaku). Investigation of effects of fractions isolated from Toki revealed that its activity mainly resided in the butanol layer and its contents of N-methyl-beta-carboline-3-carboxamide and amines. Moreover, the alkaloid, internal and external solutions (containing poly-, di-, and monosaccharides) obtained by dialysis with Visking cellophane tubing also improved the memory. However, no improving properties were detected for methanol and hexanol layers, L-(-)-tryptophan, L-arginine, L-(-)-lysine, and choline chloride. The results showed that the TSS components could improve the reference and working memory impaired by scopolamine. The improving effect of TSS is produced greatly by the Toki component, the activity of which was greatly produced by the fraction extracted by butanol. PMID:15351791

    Suan-Zao-Ren (SZR) decoction, consisting of Ziziphi Spinosae Semen, Poria, Chuanxiong Rhizoma, Anemarrhenae Rhizoma and Glycyrrhizae Radix Et Rhizoma, is a Traditional Chinese Medicine prescription, clinically used for the treatment of insomnia. The objective of this study was to develop a sensitive and reliable UFLC-MS/MS method for simultaneous quantitation of spinosin, mangiferin and ferulic acid, the main active ingredients in SZR decoction, and to compare the pharmacokinetics of these active ingredients in normal and insomnic rats orally administrated with the prescription. Analytes and IS were separated on a Shim-pack XR-ODS column (75 mm × 3.0 mm, 2.2 µm particles) using gradient elution with the mobile phase consisting of methanol and 0.1% formic acid in water at a flow rate of 0.4 mL/min. The detection of the analytes was performed on 4000Q UFLC-MS/MS system with turbo ion spray source in the negative ion and multiple reaction-monitoring mode. The lower limits of quantification were 1, 6 and 1 ng/mL for spinosin, mangiferin and ferulic acid, respectively. Intra- and inter-day precision and accuracy of analytes were well within acceptance criteria (15%). The mean extraction recoveries of analytes and IS from rats plasma were all more than 85.0%. The validated method has been successfully applied to comparing pharmacokinetic profiles of analytes in rat plasma. The results indicated that no significant difference in pharmacokinetic parameters of ferulic acid was observed between two groups, while absorptions of spinosin and mangiferin in insomnic group were significantly lower than those in normal group.

    Pure compounds extracted and purified from natural sources are crucial to lead discovery and drug screening. This study presents a novel two-dimensional hyphenation of expanded bed adsorption chromatography (EBAC) and high-speed countercurrent chromatography (HSCCC) for extraction and purification of target compounds from medicinal plants in a single step. The EBAC and HSCCC were hyphenated via a six-port injection valve as an interface. Fractionation of ingredients of Salvia miltiorrhiza and Rhizoma coptidis was performed on the hyphenated system to verify its efficacy. An amount each of 52.9 mg of salvianolic acid B and 2.1 mg of rosmarinic acid was obtained from Salvia miltiorrhiza by the two-dimensional system in a single step. The purities of the targets were over 96% of salvianolic acid B and 74% of rosmarinic acid. An amount each of 4.6 mg of coptisine and 4.1 mg of berberine was obtained from Rhizoma coptidis each with 98% and 82% purity, respectively. The processing time was nearly 50% that of the multi-step method. These results indicate that the present method is a rapid and green way to harvest targets from medicinal plants in a single step.

    A rapid sensitive analytical method was established and validated to investigate levistolide A in rat plasma by liquid chromatography-tandem mass spectrometry operated in the positive ion mode. Levistilide A (LA) and internal standard (IS) andrographolide (AD), mixed with the plasma sample, were separated on a reversed phase Spursil™ C18 5 µm column. The precursor/product transitions (m/z) were 398.5/381.3 for LA and (m/z) 368.0/351.1 for AD. The calibration curve was linear over the range from 5 to 1,250 ng/mL for oral administration and 10-4,000 for intravenous administration with a correlation coefficient (r) ≥0.9993. The lower limit of quantification was 5 ng/mL for LA in plasma. The inter- and intra-day accuracy and precision were less than ±15% of the relative standard deviation. In this study, the developed method is successfully applied to the comparative pharmacokinetic study of LA in rats after oral administration of LA alone, Rhizoma Chuanxiong, and Danggui-Shaoyao-San along with the bioavailability study of LA in rats. Our study shows that low bioavailability (7.5%) is observed after oral administration of LA. Traditional formula compatibility of Danggui-Shaoyao-San could significantly enhance LA bioavailability compared with LA alone and Rhizoma Chuanxiong. PMID:25657289

    Selective separation of chemical components from seven kinds of volatile oil by countercurrent chromatography with three types of cyclodextrins as selective reagent was investigated in this work. Preparative separation of chemical components from volatile oil is generally quite challenging due to their extremely complexity of the composition. A biphasic solvent system n-hexane-0.10 mol L(-1) cyclodextrin (1:1, v/v) was selected for separation of components from volatile oil and three types of cyclodextrins were investigated, including β-cyclodexrin, methyl-β-cyclodexrin and hydroxypropyl-β-cyclodexrin. All kinds of volatile oils are from seven kinds of traditional Chinese herb. Results showed that some chemical components could be well separated with high purity from each kind of volatile oil using different type of cyclodextrin as selective reagent. For example, germacrone and curcumenone could be selectively separated from volatile oil of Curcumae Rhizoma with methyl-β-cyclodexrin and hydroxypropyl-β-cyclodexrin as selector respectively, and other five components were selectively separated from volatile oil of Chuanxiong Rhizoma, Myristicae Semen, Aucklandiae Radix and Angelicae Sinensis Radix by countercurrent chromatography with different cyclodexrin as selective reagent. Separation mechanism for separation of components from volatile oil by countercurrent chromatography with cyclodextrin as selective reagent was proposed. Peak resolution of the present separation method could be greatly influenced by the chemical compositions of volatile oil. PMID:27036211

    Autophagy is a universal catabolic cellular process for quality control of cytoplasm and maintenance of cellular homeostasis upon nutrient deprivation and environmental stimulus. It involves the lysosomal degradation of cellular components such as misfolded proteins or damaged organelles. Defects in autophagy are implicated in the pathogenesis of diseases including cancers, myopathy, neurodegenerations, infections and cardiovascular diseases. In the recent decade, traditional drugs with new clinical applications are not only commonly found in Western medicines, but also highlighted in Chinese herbal medicines (CHM). For instance, pharmacological studies have revealed that active components or fractions from Chaihu (Radix bupleuri), Hu Zhang (Rhizoma polygoni cuspidati), Donglingcao (Rabdosia rubesens), Hou po (Cortex magnoliae officinalis) and Chuan xiong (Rhizoma chuanxiong) modulate cancers, neurodegeneration and cardiovascular disease via autophagy. These findings shed light on the potential new applications and formulation of CHM decoctions via regulation of autophagy. This article reviews the roles of autophagy in the pharmacological actions of CHM and discusses their new potential clinical applications in various human diseases. PMID:26999089

    Chunghyul-dan (CHD) is a herbal complex containing 80% ethanol extract and is composed of Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex, Gardeniae Fructus, and Rhei Rhizoma. We have published several experimental and clinical research articles on CHD. It has shown antilipidemic, antihypertensive, antiatherosclerotic, and inhibitory effects on ischemic stroke recurrence with clinical safety in the previous studies. The antilipidemic effect of CHD results from 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase and pancreatic lipase-inhibitory activity. The antihypertensive effect likely results from the inhibitory effect on endogenous catecholamine(s) release and harmonization of all components showing the antihypertensive effects. Furthermore, anti-inflammatory and antioxidant effects on endothelial cells are implicated to dictate the antiatherosclerotic effects of CHD. It also showed neuroprotective effects on cerebrovascular and parkinsonian models. These effects of CHD could be helpful for the prevention of the recurrence of ischemic stroke. Therefore, we suggest that CHD could be a promising medication for treating and preventing cerebrovascular and cardiovascular diseases. However, to validate and better understand these findings, well-designed clinical studies are required. PMID:27340412

    Ginseng Radix et Rhizoma (GRR, also named as white ginseng), Ginseng Radix et Rhizoma Rubra (GRR Rubra. also named as red ginseng), Ginseng Folium (GF) and Ginseng Rootlet (GR) products from Asian ginseng, one of the well-known Chinese traditional medicine for thousands of years, are now widely used around the world. Thus the comprehensive quality control is of paramount concern basing on the contents of the bioactive ginsenosides. A rapid, sensitive and reliable method of ultra-performance liquid chromatography coupled with a photodiode array detection (UPLC-PAD) was developed for the quantitative analysis of the 12 ginsenosides in the four commercial ginseng products of Asian ginseng. The chromatography was performed on an ACQUITY UPLC™ BEH C18 column using a gradient elution with acetonitrile/water as the mobile phases. Method validation including calibration curves, accuracies, precisions, repeatabilities and recoveries was investigated. The contents of the 12 ginsenosides were determined in 20 GRR, 4 GF, 4 GR and 11 GRR Rubra samples. To evaluate the sample quality. chenometric methods including hierarchical cluster analysis (HCA) and principal components analysis (PCA) were engaged in evaluating the GRR, GRR Rubra, GF and GR products from Asian ginseng. The results showed that HCA and PCA can be considered as the attractive chemometric techniques in situations where high sample throughput and multiple analytes are required.

    An automated on-line SPE and innovative fast polarity switch bioanalysis method employing dual-gradient liquid chromatography (DGLC) coupled with mass spectrometry (DGLC-MS/MS) was established and validated for the simultaneous determination of ferulic acid, ligustrazine and ligustilide in rat plasma after administration of Rhizoma Chuanxiong, Angelica sinensis extract or monomer. The proteins in plasma samples were precipitated using acetonitrile: methanol (1:1, v/v). Sulfamethoxazole was used as an internal standard. The DGLC system contains two high-pressure pumps. The first pump was used for on-line solid phase extraction with a Cyclone™ SPE column. Chromatographic separations were performed with the other pump on a Syncronis C18 rapid analytical column. The analytical column was eluted by a gradient program that featured an acetonitrile/methanol/water gradient (flow-rate, 0.4ml/min). DGLC afforded greater convenience for bioanalysis. All analytes were simultaneously monitored in positive- and negative-ion mode by SRM (selective reaction monitoring) using the fast polarity switch speed of TSQ Vantage™. Method validation of the assay was implemented. No significant matrix effect was observed. The LLOQ of all analytes were <1.0ng/ml. The precision, recovery and linearity of the analysis met the pre-established requirements. The method was applied to the pharmacokinetics of ferulic acid, ligustrazine and ligustilide in Rhizoma Chuanxiong or Angelica sinensis extracts or monomers. PMID:24140450

    Background: It is known that when crude Pinelliae rhizome and Pinelliae rhizoma preparatum are combined with Aconiti Radix Cocta respectively, the toxicity of the combination varies. However, the component's transformation between different compatibility have remained unclear. Objective: In this paper, a novel approach using rapid resolution liquid chromatography-quadrupole time-of-flight mass spectrometry (RRLC-Q-TOF-MS) coupled with multivariate statistical analysis was established for exploring the influence of processing adjuvants (PAs) on the compatibility of Aconiti Radix Cocta and Pinelliae rhizome. Materials and Methods: In order to obtain information about the representative markers between different groups, an exhaustive study of different protocols based on adding or removing different PAs step by step was carried out and the influence of PAs on compatibility was investigated. Results: It was found that lime can facilitate diester diterpenoid alkaloids with high toxicity in Aconiti Radix Cocta to be converted into low-toxic or non-toxic derivatives. Glycyrrhizae Radix et Rhizoma had no remarkable effect on the process. Conclusion: The established method in this study will be of great significance to process research mechanism and study on traditional Chinese Medicine compatibility and clinical application.

    Methodology for elucidating the therapeutic material basis and quality control indices of Traditional Chinese Medicinal Preparation Suanzaoren decoction was developed. Combination of Suanzaoren decoction was designed and sixteen groups were obtained. Effects on frequency of spontaneous motion, sleeping number and sleeping duration in mice were studied with sixteen combinations of Suanzaoren decoction to get the pharmacological data. RP-HPLC method was developed to analyze the chromatographic profiles of natural components in all combinations. Areas (corrected by weighting amounts) of chromatographic peaks were collected as chemical data. The pharmacological and chemical data were correlated by chemical statistical methods, and then the therapeutic material basis (thirteen chemical constituents with sedative and hypnotic effects among forty-eight chromatographic peaks) of Suanzaoren decoction were elucidated. Spinosin from Semen Ziziphi Spinosae, ferulic acid from Rhizoma Chuanxiong, mangiferin from Rhizoma Anemarrhenae and glycyrrhizic acid from Radix Glycyrrhizae were selected as quality control indices. This paper provided a new methodology for elucidating the therapeutic material basis and quality control indices for T.C.M. It is instructive for modernization of Chinese herbs and its compound preparations. PMID:16755056

    The use of health supplements derived from medicinal herbs as self-medication for the relief of respiratory tract pathology symptoms is increasing in Chinese communities as air pollution is worsening. Twelve herbs from two formulae of our previous studies were evaluated for their anti-inflammatory, immunomodulatory and bronchorelaxant activities in this study. Among the extracts tested, those of Herba Schizonepetae and Radix Glycyrrhizae showed significant inhibitory effects on LPS-induced nitric oxide production (p < 0.05) in mouse macrophage RAW264.7 cells, suggesting their anti-inflammatory activities. Radix Scutellariae and Radix Glycyrrhizae extracts showed significant inhibitory effects on phytohaemagglutinin-induced proliferation in human peripheral blood mononuclear cells (p < 0.05). These extracts also showed inhibition of TNF-α, IFN-γ and IL-10 production. For the bronchorelaxant assay, Rhizoma Cynanchi Stauntonii and Radix Glycyrrhizae extracts showed potent attenuation of the acetylcholine- and carbachol-induced contractions in rat trachea (p < 0.05), implying their relaxant activities. In conclusion, Herba Schizonepetae, Radix Glycyrrhizae, Radix Scutellariae and Rhizoma Cynanchi Stauntonii extracts were demonstrated to exert anti-inflammatory, immunomodulatory and bronchorelaxant activities, which may help to ameliorate the symptoms of respiratory tract pathologies. The findings have thus provided some scientific evidence on the efficacy and mechanisms of action of these herbs, which are useful for the further development of clinical applications. PMID:22105892

    The present study was designed to evaluate the antihypertensive effect of GaMiSamHwangSaSimTang (HVC1), a 30% ethanol extract of a mixture comprising Pruni Cortex, Scutellariae Radix, Coptidis Rhizoma, and Rhei Rhizoma, on spontaneous hypertensive rats (SHRs). The systolic blood pressure (SBP) was measured every 4 or 7 days using the noninvasive tail cuff system. The vasorelaxant effects on isolated aortic rings were evaluated. Aortic rings were contracted using phenylephrine (PE) or KCl, and the changes in tension were recorded via isometric transducers connected to a data acquisition system. In this study, oral administration of HVC1 decreased the SBP of SHRs over the experimental period. HVC1 induced concentration-dependent relaxation in the aortic rings that had been precontracted using PE or KCl. The vasorelaxant effects of HVC1 on endothelium-intact aortic rings were inhibited by pretreatment with Nω-Nitro-l-arginine methyl ester (L-NAME) or methylene blue. HVC1 inhibited the contraction induced by extracellular Ca2+ in endothelium-denuded rat aortic rings that had been precontracted using PE or KCl. In conclusion, HVC1 reduced the SBP of SHR and relaxed isolated SHR aortic rings by upregulating NO formation and the NO-cGMP pathway and blocking the entry of extracellular Ca2+ via receptor-operative Ca2+ channel and voltage-dependent Ca2+ channel.

    Chunghyul-dan (CHD) is a herbal complex containing 80% ethanol extract and is composed of Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex, Gardeniae Fructus, and Rhei Rhizoma. We have published several experimental and clinical research articles on CHD. It has shown antilipidemic, antihypertensive, antiatherosclerotic, and inhibitory effects on ischemic stroke recurrence with clinical safety in the previous studies. The antilipidemic effect of CHD results from 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase and pancreatic lipase-inhibitory activity. The antihypertensive effect likely results from the inhibitory effect on endogenous catecholamine(s) release and harmonization of all components showing the antihypertensive effects. Furthermore, anti-inflammatory and antioxidant effects on endothelial cells are implicated to dictate the antiatherosclerotic effects of CHD. It also showed neuroprotective effects on cerebrovascular and parkinsonian models. These effects of CHD could be helpful for the prevention of the recurrence of ischemic stroke. Therefore, we suggest that CHD could be a promising medication for treating and preventing cerebrovascular and cardiovascular diseases. However, to validate and better understand these findings, well-designed clinical studies are required. PMID:27340412

    Rhizoma A. officinarum (Hance) Farw, synonymously is called rhizoma galangae or smaller galangal (hereafter abbreviated as AO). Numerous studies reported that AO possesses anti-inflammatory, anticancer, chemoprotective, antibacterial, antifungal and diuretic properties. To understand whether AO exhibits antihyperlipidemic bioactivity and what is the mechanism of action, we performed chemical and animal studies using hamsters (age: 4 weeks, body weight: 45 ± 4 g). The grouping of the animals was as follows: control, high fat (HF) diet, HF + AO2%, HF + AO4%, HF + AO6%, HF + AO8% and HF + AO10%. AO contained curcumin 5.67 mg g(-1) (on wet basis), crude fiber 1.3% ± 0.0%, soluble diet fiber 92 ± 2 mg g(-1), insoluble diet fiber 502 ± 5 mg g(-1), and phytosterols 63.9 ± 1.6 mg/100 g. Its methanolic extract consisted of high polyphenolics 4927.8 ± 101.1 mgGAE/100 g and flavonoids 593.2 ± 22.2 mgQE/100 g. The enlarged organs, including liver, kidney, and spleen, which were elicited by HF were completely alleviated by AO supplement diets. Levels of serum cholesterol, triglyceride, LDL-C, HDL-C and LDL-C/HDL-C ratio for the control originally were 138 ± 6, 98 ± 4, 40 ± 5, 168 ± 7 mg dL(-1) and 0.24, which were elevated by HF to 319 ± 12, 223 ± 13, 108 ± 11, 194 ± 6 mg dL(-1) and 0.05, and alleviated completely by HF + AO8% and HF + AO10%. In vitro, AO extracts showed potent DPPH free radical-scavenging and superoxide anion scavenging capabilities. In vivo, AO (at dose ≥8%) dose-dependently alleviated levels of superoxide dismutase, catalase, GSH, and MDA to 117 ± 6.9 U mL(-1), 32.9 ± 3.7 U mL(-1), 7.0 ± 1.7 μmol mL(-1) and 1.8 ± 0.4 nmol L(-1), respectively, exhibiting the remarkable antioxidative and antihyperlipidemic effects of AO. Conclusively, we are the first to report the occurrence of curcumin in rhizoma A. officinarum. Curcumin synergistically elicits promising anti-dyslipidemic bioactivity with coexisting total polyphenolics, dietary fibers

    Liquorice is the root of Glycyrrhiza uralensis Fisch. or Glycyrrhiza glabra L., Leguminosae. Licorice is described as 'National Venerable Master' in Chinese medicine and plays paradoxical roles, i.e. detoxification/strengthen efficacy and inducing/enhancing toxicity. Therefore, licorice was called "Two-Face" herb in this paper. The aim of this study is to discuss the paradoxical roles and the perspective usage of this "Two-Face" herb using data mining and frequency analysis. More than 96,000 prescriptions from Chinese Formulae Database were selected. The frequency and the prescription patterns were analyzed using Microsoft SQL Server 2000. Data mining methods (frequent itemsets) were used to analyze the regular patterns and compatibility laws of the constituent herbs in the selected prescriptions. The result showed that licorice (Radix glycyrrhizae) was the most frequently used herb in Chinese Formulae Database, other frequently used herbs including Radix Angelicae Sinensis (Dang gui), Radix et rhizoma ginseng (Ren shen), etc. Toxic herbs such as Radix aconiti lateralis praeparata (Fu zi), Rhizoma pinelliae (Ban xia) and Cinnabaris (Zhu sha) are top 3 herbs that most frequently used in combination with licorice. Radix et rhizoma ginseng (Ren shen), Poria (Fu ling), Radix Angelicae Sinensis (Dang gui) are top 3 nontoxic herbs that most frequently used in combination with licorice. Moreover, Licorice was seldom used with sargassum (Hai Zao), Herba Cirsii Japonici (Da Ji), Euphorbia kansui (Gan Sui) and Flos genkwa (Yuan Hua), which proved the description of contradictory effect of Radix glycyrrhizae and these herbs as recorded in Chinese medicine theory. This study showed the principle pattern of Chinese herbal drugs used in combination with licorice or not. The principle patterns and special compatibility laws reported here could be useful and instructive for scientific usage of licorice in clinic application. Further pharmacological and chemical researches are

    β-Adrenergic receptors are important targets for drug discovery. We have developed a new β1 -adrenergic receptor cell membrane chromatography (β1 AR-CMC) with offline ultra-performance LC (UPLC) and MS method for screening active ingredients from traditional Chinese medicines. In this study, Chinese hamster ovary-S cells with high β1 AR expression levels were established and used to prepare a cell membrane stationary phase in a β1 AR-CMC model. The retention fractions were separated and identified by the UPLC-MS system. The screening results found that isoimperatorin from Rhizoma et Radix Notopterygii was the targeted component that could act on β1 AR in similar manner of metoprolol as a control drug. In addition, the biological effects of active component were also investigated in order to search for a new type of β1 AR antagonist. It will be a useful method for drug discovery as a leading compound resource.

    In this paper, surfactant-coated multi-walled carbon nanotubes (SC-MWNTs) have been proposed as a novel pseudostationary phase (PSP) to enhance the separation of isoquinoline alkaloids in nonaqueous capillary electrophoresis (NACE). Several parameters affecting NACE separation were studied including the MWNT concentration, the electrolyte concentration, pH* and the separation voltage. In comparison to conventional NACE, the addition of an MWNT dispersion using surfactant solutions in the electrolyte produced an important enhancement in the resolution due to the π-π interactions between the analytes and the surface of the carbon nanotubes. Using SC-MWNTs (6μgmL(-1)) as a PSP in the background electrolyte (BGE) (i.e., 20mM sodium acetate in methanol-acetonitrile (80:20, v/v)) provided the complete separation of five alkaloids. Finally, the developed method has been successfully applied to the detection and quantification of the tested compounds of Rhizoma Coptidis.

    Lactococcosis is prevalent on grey mullet (Mugil cephalus) in Hong Kong aquaculture resulting in serious economic loss. A compound formulation of Traditional Chinese Medicines (TCM) (modified Huanglian Jiedu decoction (HLJDD)) comprising Rhizoma coptidis, Radix scutellaria, Cortex phellodendri, Fructus gardeniae, Fructus forsythiae and Flos lonicerae japonicae (in a ratio of 3:2:2:3:3:5) were applied as feed supplements to deal with the disease. The Nitroblue tetrazolium activity in blood, bactericidal activity and total immunoglobulin in plasma were significantly enhanced after feeding 1% of this TCM for 28 days. The disease resistances to Lactococcus garvieae in 1% and 2% TCM feeding groups were significantly enhanced. In the in vitro study, the modified HLJDD also activated the plasma bactericidal activities (p<0.01). Based on this study, 1% modified HLJDD feeding for 28 days may be an optimal dose to prevent L. garvieae infection and could be used in aquaculture industries.

    Curcumin, the yellow pigment from the rhizoma of Curcuma longa, is a widely studied phytochemical which has a variety of biological activities: anti-inflammatory and anti-oxidative. In this review we discuss the biological mechanisms and possible clinical effects of curcumin treatment on cancer therapy, and neurodegenerative diseases such as Alzheimer's Disease, with particular attention to the cell death processes induced by curcumin. Since oxidative stress and inflammation are major determinants of the aging process, we also argue that curcumin can have a more general effect that slows down the rate of aging. Finally, the effects of curcumin can be described as xenohormetic, since it activates a sort of stress response in mammalian cells.

    Diabetic nephropathy is a progressive kidney disorder and is pathologically characterized by thickened glomerular and tubular basement membranes, accumulation of the extracellular matrix and increased mesangial hypertrophy. Growing evidence has suggested that diabetic nephropathy is induced by multiple factors, such as dyslipidemia, hyperglycemia, hemodynamic abnormalities and oxidative stress, based on genetic susceptibility. Berberine (BBR; [C20H18NO4](+)), an isoquinoline alkaloid, is the major active constituent of Rhizoma coptidis and Cortex phellodendri. Recent studies have demonstrated that berberine has various pharmacological activities, including lowering blood glucose, regulating blood lipids and reducing inflammation in addition to its antioxidant activity. These findings suggest that berberine has potential applications as a therapeutic drug for diabetic nephropathy, and has significant research value. However, the possible mechanisms have not been fully established. The purpose of this paper is to investigate the renoprotective mechanisms of berberine in diabetic nephropathy and highlight the importance of berberine as a potential therapeutic reagent for diabetic nephropathy treatment.

    Candida albicans (C. albicans) is an opportunistic fungal pathogen, particularly observed in immunocompromised patients. C. albicans accounts for 50–70% of cases of invasive candidiasis in the majority of clinical settings. Terbinafine, an allylamine antifungal drug, has been used to treat fungal infections previously. It has fungistatic activity against C. albicans. Traditional Chinese medicines can be used as complementary medicines to conventional drugs to treat a variety of ailments and diseases. Berberine is a quaternary alkaloid isolated from the traditional Chinese herb, Coptidis Rhizoma, while berberrubine is isolated from the medicinal plant Berberis vulgaris, but is also readily derived from berberine by pyrolysis. The present study demonstrates the possible complementary use of berberine and berberrubine with terbinafine against C. albicans. The experimental findings assume that the potential application of these alkaloids together with reduced dosage of the standard drug would enhance the resulting antifungal potency. PMID:27073630

    Tetramethylpyrazine (TMP) is a natural product extracted from Rhizoma Chuanxiong. Liposomes are an excellent delivery method that is suitable for the penetration of the blood-brain barrier (BBB). TMP-loaded liposomes are suitable for the treatment of cerebral ischemic diseases. We measured the morphology, particle size, zeta-potential, entrapment efficiency, and content of TMP-loaded liposome. The electrochemical method was adopted to determine entrapment efficiency for the first time. In addition, their diffusion through BBB models, which were built not only by in vitro cell culture but also by the ex vivo mouse subcutaneous-mucous-membrane (mSMM) method, was explored. The results showed that TMP and TMP-loaded liposomes could effectively permeate both BBB models. Therefore, the study indicated that liposomes were a novel carrier that could deliver TMP across the body barrier models and then release TMP slowly. PMID:27612797

    Furanodiene (FUR) is a natural terpenoid isolated from Rhizoma Curcumae, a well-known Chinese medicinal herb that presents anti-proliferative activities in several cancer cell lines. Recently, we found that the combined treatment of FUR with paclitaxel (TAX) showed synergetic anti-proliferative activities in 95-D lung cancer cells. Herein, we showed that FUR reduced the cell numbers distributed in mitosis phase induced by TAX while increased those in G1 phase. The protein levels of cyclin D1, cyclin B1, CDK6 and c-Myc were all down-regulated in the group of combined treatment. The dramatically down-regulated expression of integrin β4, focal adhesion kinase and paxillin might partially contribute to the synergic effect. Though FUR alone obviously induced endoplasmic reticulum stress, this signaling pathway may not contribute to the synergetic anti-proliferative effect as the protein expression of CHOP and BIP was similar in FUR alone and combined treatment group.

    Bacterial DNA/CpG DNA is recognized as a key molecule during the pathogenesis of sepsis. Therefore, preventing CpG DNA from binding to its receptor is considered as the most promising strategy. In the present experiments, Radix et Rhizoma Rhei had the highest CpG DNA-binding ability among the seventy-eight traditional Chinese herbs. After the isolation of silica gel chromatography and high performance liquid chromatography (HPLC) and evaluation with affinity biosensor, the active fraction was confirmed and named Fraction D. It was found that in vitro, Fraction D bound to both CpG DNA and lipid A with high affinity, and strongly inhibited LPS- and CpG DNA-induced TNF-alpha release from RAW264.7 cells in a dose-dependent manner. Furthermore, Fraction D reduced the expression of TLR9 mRNA up-regulated by CpG DNA. In vivo, Fraction D protected mice challenged with lethal heat-killed E. coli. Using HPLC method, two monomers with high affinity for CpG DNA were isolated and identified as rhein and emodin. Rhein could significantly reduce CpG DNA- and LPS-induced TNF-alpha release, but emodin only reduced CpG DNA-induced TNF-alpha release. Rhein in combination with emodin could play synergistic inhibitory effect on both CpG DNA and LPS-induced TNF-alpha release, which contributed to the bioactivity of Fraction D. In conclusion, we successfully established the platform to screen anti-CpG DNA components of traditional Chinese herbs using affinity biosensor technology, got active Fraction D from Radix et Rhizoma Rhei and determined rhein and emodin as the main bioactive ingredients in Fraction D.

    In management of metabolic syndrome, the traditional Chinese medicine (TCM) is an excellent representative in alternative and complementary medicines with a complete theory system and substantial herb remedies. In this article, basic principle of TCM is introduced and 22 traditional Chinese herbs are reviewed for their potential activities in the treatment of metabolic syndrome. Three herbs, ginseng, rhizoma coptidis (berberine, the major active compound) and bitter melon, were discussed in detail on their therapeutic potentials. Ginseng extracts made from root, rootlet, berry and leaf of Panax quinquefolium (American ginseng) and Panax ginseng (Asian ginseng), are proved for anti-hyperglycemia, insulin sensitization, islet protection, anti-obesity and anti-oxidation in many model systems. Energy expenditure is enhanced by ginseng through thermogenesis. Ginseng-specific saponins (ginsenosides) are considered as the major bioactive compounds for the metabolic activities of ginseng. Berberine from rhizoma coptidis is an oral hypoglycemic agent. It also has anti-obesity and anti-dyslipidemia activities. The action mechanism is related to inhibition of mitochondrial function, stimulation of glycolysis, activation of AMPK pathway, suppression of adipogenesis and induction of low-density lipoprotein (LDL) receptor expression. Bitter melon or bitter gourd (Momordica charantia) is able to reduce blood glucose and lipids in both normal and diabetic animals. It may also protect β cells, enhance insulin sensitivity and reduce oxidative stress. Although evidence from animals and humans consistently supports the therapeutic activities of ginseng, berberine and bitter melon, multi-center large-scale clinical trials have not been conducted to evaluate the efficacy and safety of these herbal medicines.

    Our previous study showed that free fructose is an important active constituent responsible for Si-Wu-Tang's (SWT) effect promoting hematopoiesis and immunity. However, the contribution from SWT's four ingredient drugs to the free fructose content in the SWT decoction was not clear. To answer this question, in this study, the fructose, glucose and sucrose content in the SWT decoction, in the decoctions of each single ingredient drug, and in the decoctions of the four formulae lacking each single ingredient drug were determined by HPLC-ELSD. The results showed that the fructose and glucose content in the decoction of single Rehmanniae Radix were almost the same as those in the SWT decoction. In the single Rehmanniae Radix decoction concentrations were: 4.25 ± 0.53 mg/mL for fructose, and 3.43 ± 0.60 mg/mL for glucose; in the SWT decoction concentrations were: 4.10 ± 0.43 mg/mL for fructose, and 3.42 ± 0.32 mg/mL for glucose, while the content of fructose and glucose in the decoctions of single Angelica Radix, single Paeoniae Radix, single Chuanxiong Rhizoma and the formula lacking Rehmanniae Radix were either very small or undetectable. On the other hand, the fructose and glucose content in the decoctions of the formulae lacking Angelica Radix, lacking Paeoniae Radix and lacking Chuanxiong Rhizoma also were approximately the same as those in the SWT decoction. This indicated that Rehmanniae Radix provides most of the free fructose and glucose in the SWT decoction, and therefore plays an important role in SWT's effect promoting hematopoiesis and immunity. As for sucrose in the SWT decoction, Angelica Radix was shown to be a major donor.

    Grazing can accelerate and alter the timing of nutrient transfer, and could increase the amount of extractable phosphorus (P) cycle from soils to plants. The effects of grazing management and/or forage type that control P cycling and distribution in pasture's resources have not been sufficiently evaluated. Our ability to estimate the levels and changes of soil-extractable P and other crop nutrients in subtropical beef cattle pastures has the potential to improve our understanding of P dynamics and nutrient cycling at the landscape level. To date, very little attention has been paid to evaluating transfers of extractable P in pasture with varying grazing management and different forage type. Whether or not P losses from grazed pastures are significantly greater than background losses and how these losses are affected by soil, forage management, or stocking density are not well understood. The objective of this study was to evaluate the effect of grazing management (rotational versus "zero" grazing) and forage types (FT; bahiagrass, Paspalum notatum, Flugge versus rhizoma peanuts, Arachis glabrata, Benth) on the levels of extractable soil P and degree of P saturation in beef cattle pastures. This study (2004-2007) was conducted at the Subtropical Agricultural Research Station, US Department of Agriculture-Agricultural Research Service located 7 miles north of Brooksville, FL. Soil (Candler fine sand) at this location was described as well-drained hyperthermic uncoated Typic Quartzipsamments. A split plot arrangement in a completely randomized block design was used and each treatment was replicated four times. The main plot was represented by grazing management (grazing vs. no grazing) while forage types (bahiagrass vs. perennial peanut) as the sub-plot treatment. Eight steel exclosures (10 × 10 m) were used in the study. Four exclosures were placed and established in four pastures with bahiagrass and four exclosures were established in four pastures with rhizoma

    Senkyunolide I is an active ingredient of Rhizoma Chuanxiong, a Chinese medicinal herb commonly used for the treatment of cardiovascular ailments. In the present paper, we describe the isolation and elucidation of senkyunolide I from the ethanol extract of Rhizoma Chuanxiong and its pharmacokinetic behavior after intravenous and oral administration to normal and migrainous rats. After intravenous administration, senkyunolide I was rapidly distributed (V ( z )/F 2.07 ± 0.43 L/kg) and eliminated from the plasma (CL( z ) 2.56 ± 0.29 L/h/kg and t (1/2z ) 0.56 ± 0.13 h). After administration orally to normal rats at two dosages (20 and 72 mg/kg), the pharmacokinetic parameters of senkyunolide I were as follows: T (max) 0.25 ± 0.06 and 0.38 ± 0.11 h, C (max) 5,236.3 ± 802.8 and 22,071.9 ± 3,456.1 mg/L, Area under the curve(AUC)((0-t)) 5,217.5 ± 1,029.5 and 21,480.2 ± 3,003.1 μg h/L, respectively. Its oral absolute bioavailability at the two dosages was 67.2 and 76.9%, respectively. Intriguingly, migraine caused some significant changes in its pharmacokinetic parameter. For example, when compared with its pharmacokinetic behavior in normal rats at the two dosages, on average, its clearance decreased by 68% and volume of distribution increased by 342% in migrainous rats, both of which contributed to its several-fold increase in t (1/2z) and AUC. C (max) and AUC of senkyunolide I increased almost proportionally with dose between 20 and 72 mg/kg and the pharmacokinetics fit linear kinetic feature. The pharmacokinetic parameters of senkyunolide I were significantly different in normal and migrainous rats, which should be taken into account during the design of a clinical dosage regimen for senkyunolide I.

    Sheng Hua Tang, a classical herbal formula consisting of Radix Angelicae sinensis, Ligustici rhizoma, Semen persicae, Zingiberis rhizoma, and Radix glycyrrhizae, is known to be beneficial in alleviating postpartum diseases and facilitating a return to normal reproductive function. This study investigated whether the administration of Sheng Hua Tang within 2 to 4 hours after delivery was effective as a preventive treatment for reducing the risk of retained placenta in Holstein dairy cows. A total of 357 cows, each of which had delivered its calf spontaneously, were randomly allocated to one of two groups. In the treatment group, the cows (n = 175) received Sheng Hua Tang with an oral dose of 0.36 g crude herb per kg·body weight once daily for three consecutive days. The controls (n = 182) received no treatment. The placental retention proportion was 4.0% and 17.0% within 12 hours after delivery in the treated and control animals, respectively (P < 0.01). We found decreases in the calving-to-first-service interval (73.2 ± 25.1 vs. 81.9 ± 32.8 days; P < 0.01), calving-to-conception interval (93.4 ± 38.8 vs. 114.6 ± 42.9 days; P < 0.01), and service per conception (1.5 ± 0.8 vs. 1.9 ± 1.0 days; P < 0.01) in the treatment group compared with the control group. The first artificial insemination conception proportion was higher in the treatment group than in the control group (60.4% vs. 41.1%; P = 0.01). Moreover, the between-group difference in the proportion of cows that were pregnant within 180 days postpartum approached statistical significance (88.2% vs. 80.6%; P = 0.07). Sheng Hua Tang showed beneficial effects in reducing the incidence of retained placenta and improving subsequent reproductive performance in cows. This preventive treatment strategy would be effective in improving the management of puerperal health. The potential benefits of Sheng Hua Tang warrant further investigation to determine whether this preventive treatment strategy can be endorsed as

    Development of anti-severe acute respiratory syndrome associated coronavirus (SARS-CoV) agents is pivotal to prevent the reemergence of the life-threatening disease, SARS. In this study, more than 200 extracts from Chinese medicinal herbs were evaluated for anti-SARS-CoV activities using a cell-based assay that measured SARS-CoV-induced cytopathogenic effect (CPE) in vitro on Vero E6 cells. Six herbal extracts, one each from Gentianae Radix (龍膽 lóng dǎn; the dried rhizome of Gentiana scabra), Dioscoreae Rhizoma (山藥 shān yào; the tuber of Dioscorea batatas), Cassiae Semen (決明子 jué míng zǐ; the dried seed of Cassia tora) and Loranthi Ramus (桑寄生 sāng jì shēng; the dried stem, with leaf of Taxillus chinensis) (designated as GSH, DBM, CTH and TCH, respectively), and two from Rhizoma Cibotii (狗脊 gǒu jǐ; the dried rhizome of Cibotium barometz) (designated as CBE and CBM), were found to be potent inhibitors of SARS-CoV at concentrations between 25 and 200 μg/ml. The concentrations of the six extracts needed to inhibit 50% of Vero E6 cell proliferation (CC50) and 50% of viral replication (EC50) were determined. The resulting selective index values (SI = CC50/EC50) of the most effective extracts CBE, GSH, DBM, CTH and TCH were > 59.4, > 57.5, > 62.1, > 59.4, and > 92.9, respectively. Among these extracts, CBM and DBM also showed significant inhibition of SARS-CoV 3CL protease activity with IC50 values of 39 μg/ml and 44 μg/ml, respectively. Our findings suggest that these six herbal extracts may have potential as candidates for future development of anti-SARS therapeutics.

    The clinical applications of Rhizoma paridis in traditional Chinese medicine are well known. However, the therapeutic potential of Rhizoma paridis and its active component such as Paris saponin I (polyphyllin D) and Paris saponin II (PSII) (formosanin C) in cancer treatments have not yet been fully explored. Recent studies have demonstrated that PSII and chemoagents exhibit comparable inhibitory affects against human ovarian cancer cell growth. Since NF-κB, a ubiquitous transcription factor that plays an important role in cancer biology, is often associated with gynecological cancers, in the present study, we evaluated the possibility that PSII modulates NF-κB activity and VEGF-mediated angiogenesis and elucidated the molecular mechanisms underlying such effects. We assessed the effects of PSII on NF-κB activity in SKOV3 tumor cells and on tumor cell induced-angiogenesis using standardized angiogenesis in vitro, ex vivo and in vivo assays, western blot analysis and kinase assay. We also assessed the effect of the super-engineered repressor of IĸBα and its effect, in combination with PSII treatment on tumor growth and angiogenesis in xenograft athymic mouse models of ovarian cancer (SKOV3 and SKOV3/mutant IĸBα cells) using color Doppler ultrasound and traditional immunohistochemistry. We showed that PSII suppressed NF-κB activation as a result of the reduction in IKKβ kinase activity on its substrate IκBα and the expression of IKKβ. Compromising NF-κB activation reduced the expression of NF-κB-downstream targets such as VEGF, Bcl-2 and Bcl-xL. Such inhibitory effects at molecular levels appear to compromise tumor growth and angiogenesis. Most importantly, the combination of PSII treatment and constitutive repression of IĸBα activity exhibited marked inhibitory effects against human ovarian cancer cell growth in a xenograft mouse model of ovarian cancer. For the first time, we provide evidence showing that PSII potently inhibits angiogenesis

    Feline calicivirus (FCV) often causes respiratory tract and oral disease in cats and is a highly contagious virus. Widespread vaccination does not prevent the spread of FCV. Furthermore, the low fidelity of the RNA-dependent RNA polymerase of FCV leads to the emergence of new variants, some of which show increased virulence. Currently, few effective anti-FCV drugs are available. Here, we found that germacrone, one of the main constituents of volatile oil from rhizoma curcuma, was able to effectively reduce the growth of FCV strain F9 in vitro. This compound exhibited a strong anti-FCV effect mainly in the early phase of the viral life cycle. The antiviral effect depended on the concentration of the drug. In addition, germacrone treatment had a significant inhibitory effect against two other reference strains, 2280 and Bolin, and resulted in a significant reduction in the replication of strains WZ-1 and HRB-SS, which were recently isolated in China. This is the first report of antiviral effects of germacrone against a calicivirus, and extensive in vivo research is needed to evaluate this drug as an antiviral therapeutic agent for FCV.

    Natural products (NPs) are important sources of lead compounds in modern drug discovery. To facilitate the screening of volatile active compounds in NPs, we have developed a new biochromatography method that uses rat vascular smooth muscle cells (VSMC), which are rich in L-type calcium channels (LCC), to prepare the stationary phase. This integrated method, which couples cell membrane chromatography (CMC) with gas chromatography-mass spectrometry (GC-MS) via microextraction by packed sorbent (MEPS) technology, has been termed VSMC/CMC-MEPS-GC-MS. Methodological validation confirmed its specificity, reliability and convenience. Screening results for Radix Angelicae Dahuricae and Fructus Cnidii obtained using VSMC/CMC-MEPS-GC-MS were consistent with those obtained using VSMC/CMC-offline-GC-MS. MEPS connection plays as simplified solid-phase extraction and replaces the uncontrollable evaporation operation in reported offline connections, so our new method is supposed to be more efficient and reliable than the offline ones, especially for compounds that are volatile, thermally unstable or difficult to purify. In application, senkyunolide A and ligustilide were preliminary identified as the volatile active components in Rhizoma Chuanxiong. We have thus confirmed the suitability of VSMC/CMC-MEPS-GC-MS for volatile active compounds screening in NP.

    Constipation is characterized by a variety of bowel symptoms such as difficulty passing stool, hard stool, and a feeling of incomplete evacuation. The multifactorial causes of constipation limit the clinical efficacy of current conventional treatments that use a single drug that acts through only one pathway. To complement the shortcomings of the current Western medical model and provide a complete holistic approach, herbal medicines capable of targeting multiple organs and cellular sites may be used. In Japan, many herbs and herbal combinations have traditionally been used as foods and medicines. Currently, Japanese physicians use standardized herbal combinations that provide consistent and essential quality and quantity. This review highlights representative Japanese herbal medicines (JHMs), Rhei rhizoma-based JHMs including Daiokanzoto and Mashiningan, and Kenchuto-based JHMs including Keishikashakuyakuto and Daikenchuto, which coordinate the motility of the alimentary tract. This review provides a framework to better understand the clinical and pharmacological efficacies of JHMs on constipation according to the unique theory of Japanese traditional medicine, known as Kampo medicine.

    Jia-Yuan-Qing pill (JYQP) composed of Porcellio laevis Latreille, Corydalis Rhizoma and Radix Cynanchi Paniculati at a ratio of 9:7:7 has been found to be an effective analgesic agent. The present study aimed to evaluate the safety, addictive potential and anti-cancer pain activity of JYQP in a rat model. During the 6-month chronic toxicity test, no significant changes in general behavior, defecation, postural abnormalities, dietary or water intake or blood biochemical parameters were observed in male and female rats. Although a high dose of JYQP (5 g/kg) caused swelling of the liver, spleen and kidney in male and female rats, no pathological changes were observed in all organs examined via hematoxylin and eosin staining. The analgesic effect of JYQP on bone cancer pain was successfully confirmed in a rat model of Walker 256 cell-induced bone cancer. In contrast to morphine, in a physical dependence test, JYQP produced no withdrawal symptoms following chronic administration. The data from this study provide experimental evidence supporting the clinical use of JYQP as an effective, safe and non-addictive agent for the treatment of bone cancer pain. PMID:26136985

    Xiang-qi-tang (XQT) is a Chinese herbal formula containing rhizoma Cyperi, Andrographis paniculata and Astragalus membranaceus. The present study investigated the effects of XQT on the mortality and inflammatory mediators in a chicken model challenged with avian pathogenic Escherichia coli (APEC). To detect the effect of XQT, the chickens were pretreated with the formula 12 h before being challenged with 10(8) colony forming unit (CFU) of APEC. The results showed that 0.6 g/kg XQT significantly elevated the survival rate of infected chickens. To further investigate the mechanism of decreasing mortality of XQT, we examined plasma inflammatory mediator levels. The levels of tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1) and soluble endothelial protein C receptor (sEPCR) were significantly increased in chickens challenged with APEC alone, whereas chickens pretreated with 0.6 g/kg XQT showed marked decrease of these inflammatory mediator levels during the death peak. Taken together, this study demonstrates that XQT has protective effects in APEC-treated chickens. The action mechanisms of XQT involve anti-inflammation and antithrombotic activity. These findings may contribute to future research on the action mechanisms of this formula, as well as prevention of or therapy for avian colibacillosis.

    Curcumin, a type of natural active ingredient, is derived from rhizoma of Curcuma, which possesses antioxidant, antitumorigenic and anti‑inflammatory activities. The present study aimed to investigate whether treatment with curcumin reduced high‑fat diet (HFD)‑induced spermatogenesis dysfunction. Sprague‑Dawley rats fed a HFD were treated with or without curcumin for 8 weeks. The testis/body weight, histological analysis and serum hormone levels were used to evaluate the effects of curcumin treatment on spermatogenesis dysfunction induced by the HFD. In addition, the expression levels of apoptosis associated proteins, Fas, B‑cell lymphoma (Bcl)‑xl, Bcl‑associated X protein (Bax) and cleaved‑caspase 3, were determined in the testis. The results of the present study suggested that curcumin treatment attenuated decreased testis/body weight and abnormal hormone levels. Morphological changes induced by a HFD were characterized as atrophied seminiferous tubules, decreased spermatogenetic cells and interstitial cells were improved by curcumin treatment. In addition, curcumin treatment reduced apoptosis in the testis, and decreased expression of Fas, Bax and cleaved‑caspase 3, as well as increased expression of Bcl‑xl. In conclusion, the present study revealed that curcumin treatment reduced HFD‑induced spermatogenesis dysfunction in male rats. PMID:27600729

    Hormesis is a phenomenon of biphasic dose response characterized by exhibiting stimulatory or beneficial effects at low doses and inhibitory or toxic effects at high doses. Increasing numbers of chemicals of various types have been shown to induce apparent hormetic effect on cancer cells. However, the underlying significance and mechanisms remain to be elucidated. Berberine, one of the major active components of Rhizoma coptidis, has been manifested with notable anticancer activities. This study aims to investigate the hormetic effect of berberine and its influence on the anticancer activities of chemotherapeutic agents. Our results demonstrated that berberine at low dose range (1.25 ~ 5 μM) promoted cell proliferation to 112% ~170% of the untreated control in various cancer cells, while berberine at high dose rage (10 ~ 80 μM) inhibited cell proliferation. Further, we observed that co-treatment with low dose berberine could significantly attenuate the anticancer activity of chemotherapeutic agents, including fluorouracil (5-FU), camptothecin (CPT), and paclitaxel (TAX). The hormetic effect and thereby the attenuated anticancer activity of chemotherapeutic drugs by berberine may attributable to the activated protective stress response in cancer cells triggered by berberine, as evidenced by up-regulated MAPK/ERK1/2 and PI3K/AKT signaling pathways. These results provided important information to understand the potential side effects of hormesis, and suggested cautious application of natural compounds and relevant herbs in adjuvant treatment of cancer.

    Endometritis is a common disease in animal production and influences breeding all over the world. Berberine is one of the main alkaloids isolated from Rhizoma coptidis. Previous reports showed that berberine has anti-inflammatory potential. However, there have been a limited number of published reports on the anti-inflammatory effect of berberine hydrochloride on LPS-induced endometritis. The purpose of the present study was to investigate the effects of berberine hydrochloride on LPS-induced mouse endometritis. Berberine hydrochloride was administered intraperitoneally at 1h before and 12h after LPS induction. Then, a biopsy was performed, and uterine myeloperoxidase (MPO) and nitric oxide (NO) concentrations were determined. Tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) levels in the uterus homogenate were measured by ELISA. The extent of IκB-α and P65 phosphorylation was detected by Western blot. The results showed that berberine hydrochloride significantly attenuated neutrophil infiltration, suppressed myeloperoxidase activity and decreased NO, TNF-αand IL-1βproduction. Furthermore, berberine hydrochloride inhibited the phosphorylation of the NF-κB p65 subunit and the degradation of its inhibitor, IκBα. These findings suggest that berberine hydrochloride exerts potent anti-inflammatory effects on LPS-induced mouse endometritis and might be a potential therapeutic agent for endometritis.

    Chemotherapy-induced neuropathy (CIPN) has a relevant impact on the quality of life of cancer patients. There are no curative conventional treatments, so further options have to be investigated. We conducted a systematic review in English and Chinese language databases to illuminate the role of medical herbs. 26 relevant studies on 5 single herbs, one extract, one receptor-agonist, and 8 combinations of herbs were identified focusing on the single herbs Acorus calamus rhizoma, Cannabis sativa fructus, Chamomilla matricaria, Ginkgo biloba, Salvia officinalis, Sweet bee venom, Fritillaria cirrhosae bulbus, and the herbal combinations Bu Yang Huan Wu, modified Bu Yang Huan Wu plus Liuwei Di Huang, modified Chai Hu Long Gu Mu Li Wan, Geranii herba plus Aconiti lateralis praeparata radix , Niu Che Sen Qi Wan (Goshajinkigan), Gui Zhi Jia Shu Fu Tang (Keishikajutsubuto), Huang Qi Wu Wu Tang (Ogikeishigomotsuto), and Shao Yao Gan Cao Tang (Shakuyakukanzoto). The knowledge of mechanism of action is still limited, the quality of clinical trials needs further improvement, and studies have not yielded enough evidence to establish a standard practice, but a lot of promising substances have been identified. While CIPN has multiple mechanisms of neuronal degeneration, a combination of herbs or substances might deal with multiple targets for the aim of neuroprotection or neuroregeneration in CIPN.

    We present a systematic review of existing research that aims to assess the efficacy and safety of herbal medications (HM), as either monotherapy or adjunct to orthodox medications (OM), mainly comprised of cholinesterase inhibitors, for vascular dementia (VaD). We included 47 studies conducted in mainland China, each testing different HM. Of 43 HM monotherapy studies, 37 reported HM to be significantly better than OM or placebo; six reported similar efficacy between HM and OM. All four HM adjuvant studies reported significant efficacy. No major adverse events for HM were reported. Heterogeneity in diagnostic criteria, interventions and outcome measures hindered comprehensive data analysis. Studies suggested that HM can be a safe and effective treatment for VaD, either alone or in conjunction with OM. However, methodological flaws in the design of the studies limited the extent to which the results could be interpreted. Thirty most commonly used herbal constituents, including Rhizoma Chuanxiong (Chuanxiong in Chinese), Radix Polygoni Multiflori (Heshouwu in Chinese) and Radix Astragali (Huangqi in Chinese). were ranked. Further multi-center trials with large sample sizes, high methodological quality and standardized HM ingredients are necessary for clinical recommendations to be made. PMID:22235231

    Kushen (Radix Sophorae Flavescentis) has a long history of use for the treatment of tumors, inflammation and other diseases in traditional Chinese medicine. Compound Kushen Injection (CKI) is a mixture of natural compounds extracted from Kushen and Baituling (Rhizoma Smilacis Glabrae). The main principles of CKI are matrine (MT) and oxymatrine (OMT) that exhibit a variety of pharmacological activities, including anti-inflammatory, anti-allergic, anti-viral, anti-fibrotic and cardiovascular protective effects. Recent evidence shows that these compounds also produce anti-cancer actions, such as inhibiting cancer cell proliferation, inducing cell cycle arrest, accelerating apoptosis, restraining angiogenesis, inducing cell differentiation, inhibiting cancer metastasis and invasion, reversing multidrug resistance, and preventing or reducing chemotherapy- and/or radiotherapy-induced toxicity when combined with chemotherapeutic drugs. In this review, we summarize recent progress in studying the anti-cancer activities of MT, OMT and CKI and their potential molecular targets, which provide clues and references for further study.

    Weichang’an (WCA) pill, a traditional Chinese patent medicine consisting of ten Chinese medicinal herbs, has been used to treat irritable bowel syndrome and functional dyspepsia for several decades. In this study, twelve bioactive constituents in the methanol extract of WCA were accurately identified since MS/MS fragmentation behavior of the references and the standards by using HPLC-DAD-ESI-MS/MS analysis and a reliable and accurate method for the simultaneous determination was developed. Twelve active components including costunolide and dehydrodehydrocostus lactone from the principal herb Radix Aucklandiae; naringin, hesperidin and neohesperidin from Fructus Aurantii; magnolol and honokiol from the ministerial herbs Cortex Magnoliae officinalis; aloe-emodin, rhein, emodin, chrysophanol and physcion from adjunctive and messenger herb Radix et Rhizoma Rhei were analyzed in the samples. The chromatographic separation was performed on a Kromasil C18 column with gradient elution of acetonitrile-methanol and 1.0% acetic acid water. In this condition, linearity, inter- and intra-day precision and accuracy were within acceptable ranges. The developed method showed satisfactory precision and accuracy with overall intra- and inter-day variations of 0.68-1.33% and 0.67-2.05% respectively, and the overall recoveries of 97.54-102.69% for twelve compounds. The proposed approach was successfully applied as a powerful tool for the quality control of WCA pill. PMID:24250567

    A novel capillary electrophoresis (CE) method was developed for simultaneous analysis of adenosine deaminase (ADA) and purine nucleoside phosphorylase (PNP) in red blood cells (RBCs). The developed method considered and took advantage of the natural conversion from the ADA product, inosine to hypoxanthine. The transformation ratio was introduced for ADA and PNP analysis to obtain more reliable results. After optimizing the enzymatic incubation and electrophoresis separation conditions, the determined activities of ADA and PNP in 12 human RBCs were 0.237-0.833 U/ml and 9.013-10.453 U/ml packed cells, respectively. The analysis of ADA in mice RBCs indicated that there was an apparent activity difference between healthy and hepatoma mice. In addition, the proposed method was also successfully applied in the inhibitor screening from nine traditional Chinese medicines, and data showed that ADA activities were strongly inhibited by Rhizoma Chuanxiong and Angelica sinensis. The inhibition effect of Angelica sinensis on ADA is first reported here and could also inhibit PNP activity. PMID:27173606

    Si-Wu-Tang (SWT) is a decoction consisting of a mixture of ingredients of Rehmanniae Radix, Angelica Radix, Chuanxiong Rhizoma and Paeoniae Radix. As a traditional Chinese herbal decoction, SWT has been widely used for the treatment of diseases characterized as blood and/or energy deficit. The present study was performed to evaluate the effects of SWT on the different populations of circulating white blood cells (WBCs) and gastrointestinal changes in γ-ray irradiated mice. Female mice were treated daily with orally administered SWT seven days before irradiation, until one day before irradiation or until one day before sample collection. WBC counts were determined from peripheral blood samples taken from the mice at different times post-irradiation. Hematoxylin and eosin (H&E) staining, as well as immunohistochemical analysis of fibrinogen, were utilized to evaluate the effects of SWT in the intestines of mice after radiation exposure. The results of the present studies demonstrate that SWT has protective effects against radiation damage to circulating WBCs, specifically to lymphocytes, and to the gastrointestinal tract of the irradiated animals.

    Background and Objectives. Oxidative stress can initiate endothelial dysfunction and atherosclerosis. This study evaluated whether tetramethylpyrazine (TMP), the predominant active ingredient in Rhizoma Ligustici Wallichii (chuanxiong), prevents endothelial dysfunction in a rat model of oxidative stress. Methods. Isolated rat aortic rings were pretreated with various drugs before the induction of endothelial dysfunction by hydrogen peroxide (H2O2). Changes in isometric tension were then measured in acetylcholine- (ACh-) relaxed rings. Endothelial nitric oxide synthase (eNOS) expression was evaluated in the rings by Western blotting, and superoxide anion (O2 (∙-)) content was assessed in primary rat aortic endothelial cells by dihydroethidium- (DHE-) mediated fluorescence microscopy. Results. ACh-induced endothelium-dependent relaxation (EDR) was disrupted by H2O2 in endothelium-intact aortic rings. H2O2-impaired relaxation was ameliorated by acute pretreatment with low concentrations of TMP, as well as by pretreatment with catalase and the NADPH oxidase inhibitors, apocynin and diphenyleneiodonium (DPI). TMP, apocynin, and DPI also reduced O2 (∙-) accumulation in endothelial cells,but TMP failed to alter eNOS expression in aortic rings incubated with H2O2. Conclusions. TMP safeguards against oxidative stress-induced endothelial dysfunction, suggesting that the agent might find therapeutic utility in the management of vascular diseases. However, TMP's role in inhibiting NADPH oxidase and its vascular-protective mechanism of action requires further investigation. PMID:25258643

    Ligustrazine is the most abundant and bioactive ingredient in Rhizoma Chuanxiong, a Chinese medicinal herb commonly used for the treatment of cardiovascular diseases. Chf197 is one of the structurally modified ligustrazine derivatives in a purpose of overcoming the rapid metabolism and short half-life of original. The plasma and urine pharmacokinetics of Chf197 in rats were studied after intravenous or intraperitoneal injection of Chf197 with the validated RP-HPLC method. The pharmacokinetic parameters of Chf197 injected intravenously 20 mg/kg were as follows: Cmax , 1.44 ± 0.4 mg/L; Tmax , 0.08 h; t1/2 , 3.03 ± 1.67 h; AUC, 3.85 ± 3.88 h/L; Vd , 31.66 ± 11.79L/kg; and CL, 9.29 ± 4.92 l/h/kg. Dose-dependent pharmacokinetics was observed, and a significantly higher dose-normalized AUC after intravenous administration was obtained than that after intraperitoneal administration. A possible metabolite was detected at about 3.1 min, and full-scan mass spectrum was adopted to predict its possible structure. PMID:26182951

    Natural products (NPs) are important sources of lead compounds in modern drug discovery. To facilitate the screening of volatile active compounds in NPs, we have developed a new biochromatography method that uses rat vascular smooth muscle cells (VSMC), which are rich in L-type calcium channels (LCC), to prepare the stationary phase. This integrated method, which couples cell membrane chromatography (CMC) with gas chromatography-mass spectrometry (GC-MS) via microextraction by packed sorbent (MEPS) technology, has been termed VSMC/CMC-MEPS-GC-MS. Methodological validation confirmed its specificity, reliability and convenience. Screening results for Radix Angelicae Dahuricae and Fructus Cnidii obtained using VSMC/CMC-MEPS-GC-MS were consistent with those obtained using VSMC/CMC-offline-GC-MS. MEPS connection plays as simplified solid-phase extraction and replaces the uncontrollable evaporation operation in reported offline connections, so our new method is supposed to be more efficient and reliable than the offline ones, especially for compounds that are volatile, thermally unstable or difficult to purify. In application, senkyunolide A and ligustilide were preliminary identified as the volatile active components in Rhizoma Chuanxiong. We have thus confirmed the suitability of VSMC/CMC-MEPS-GC-MS for volatile active compounds screening in NP. PMID:25463192

    Guizhi decoction (GZD), a well-known traditional Chinese medicine (TCM) prescription consisting of Ramulus Cinnamomi, Radix Paeoniae Alba, Radix Glycyrrhizae, Fructus Jujubae and Rhizoma Zingiberis Recens, is usually used for the treatment of common colds, influenza, and other pyretic conditions in the clinic. However, the absorbed ingredients and metabolic compounds of GZD have not been reported. In this paper, a method incorporating rapid resolution liquid chromatography (RRLC) with quadrupole-time-of-flight mass spectrometry (Q-TOF-MS) was used to identify ingredients after oral administration of GZD. Identification of the primary components in GZD, drug-containing serum and urine samples was carried out in order to investigate the assimilation and metabolites of the decoction in vivo. By comparing the total ion chromatograms (TICs) of GZD, a total of 71 constituents were detected or characterized. By comparing TICs of blank and dosed rat plasma, a total of 15 constituents were detected and identified as prototypes according to their retention time (tR) and MS, MS/MS data. Based on this, neutral loss scans of 80 and 176 Da in samples of rat plasma and urine helped us to identify most of the metabolites. Results showed that the predominant metabolic pathways of (epi) catechin and gallic acid were sulfation, methylation, glucuronidation and dehydroxylation; the major metabolic pathways of flavone were hydrolysis, sulfation and glucuronidation. Furthermore, degradation, oxidation and ring fission were found to often occur in the metabolism process of GZD in vivo. PMID:27626411

    A Gram-stain-negative, Na(+)-requiring bacterial strain, designated B20-1(T), was isolated from soil of the root system of mangrove forest. Cells were curved rods and motile by means of a polar flagellum. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain B20-1(T) belonged to the genus Marinomonas , sharing highest sequence similarities with Marinomonas rhizomae IVIA-Po-145(T) (97.6%), Marinomonas dokdonensis DSW10-10(T) (97.0%) and Marinomonas foliarum IVIA-Po-155(T) (96.9%). The predominant cellular fatty acids of strain B20-1(T) were C10 : 0 3-OH, C18 : 1ω7c, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C16 : 0. Phosphatidylethanolamine and phosphatidylglycerol were identified as the predominant phospholipids. The predominant ubiquinone was Q-8. The genomic DNA G+C content of strain B20-1(T) was 46.6 mol%. On the basis of phenotypic characteristics, phylogenetic analysis and DNA-DNA relatedness, a novel species, Marinomonas mangrovi sp. nov., is proposed with B20-1(T) ( =DSM 28136(T) =LMG 28077(T)) as the type strain.

    Tetrahydropalmatine (THP), with one chiral center, is an active alkaloid ingredient in Rhizoma Corydalis. The aim of the present paper is to study whether THP enantiomers are metabolized stereoselectively in rat, mouse, dog, and monkey liver microsomes, and then, to elucidate which Cytochrome P450 (CYP) isoforms are predominately responsible for the stereoselective metabolism of THP enantiomers in rat liver microsomes (RLM). The results demonstrated that (+)-THP was preferentially metabolized by liver microsomes from rats, mice, dogs, and monkeys, and the intrinsic clearance (Cl(int)) ratios of (+)-THP to (-)-THP were 2.66, 2.85, 4.24, and 1.67, respectively. Compared with the metabolism in untreated RLM, the metabolism of (-)-THP and (+)-THP was significantly increased in dexamethasone (Dex)-induced and β-naphthoflavone (β-NF)-induced RLM; meanwhile, the Cl(int) ratios of (+)-THP to (-)-THP in Dex-induced and β-NF-induced RLM were 5.74 and 0.81, respectively. Ketoconazole had stronger inhibitory effect on (+)-THP than (-)-THP, whereas fluvoxamine had stronger effect on (-)-THP in untreated and Dex-induced or β-NF-induced RLM. The results suggested that THP enantiomers were predominately metabolized by CYP3A1/2 and CYP1A2 in RLM, and CYP3A1/2 preferred to metabolize (+)-THP, whereas CYP1A2 preferred (-)-THP.

    Highlights: • This paper supports the anti-tumor effects of AT-I on gastric cancer in vitro. • AT-I attenuates gastric cancer stem cell traits. • It is the systematic study regarding AT-I suppression of Notch pathway in GC and GCSLCs. - Abstract: Atractylenolide I (AT-I), one of the main naturally occurring compounds of Rhizoma Atractylodis Macrocephalae, has remarkable anti-cancer effects on various cancers. However, its effects on the treatment of gastric cancer remain unclear. Via multiple cellular and molecular approaches, we demonstrated that AT-I could potently inhibit cancer cell proliferation and induce apoptosis through inactivating Notch pathway. AT-I treatment led to the reduction of expressions of Notch1, Jagged1, and its downstream Hes1/ Hey1. Our results showed that AT-I inhibited the self-renewal capacity of gastric stem-like cells (GCSLCs) by suppression of their sphere formation capacity and cell viability. AT-I attenuated gastric cancer stem cell (GCSC) traits partly through inactivating Notch1, leading to reducing the expressions of its downstream target Hes1, Hey1 and CD44 in vitro. Collectively, our results suggest that AT-I might develop as a potential therapeutic drug for the treatment of gastric cancer.

    The sesquiterpenoid curdione is one of the main bioactive components in the essential oil of Rhizoma Curcumae (Curcuma wenyujin, Curcuma phaeocaulis, and Curcuma kwangsiensis), which has been clinically used for the treatment of cancer in mainland China. Recently it was reported that natural curdione could be hydroxylated by Aspergillus niger and transferred to its corresponding curcumalactones under acidic conditions. Based on this study, the development of a sesquiterpenoid library through the "mirror-image" manipulation of bioactive (non)natural curdione scaffolds by chemical and biological approaches is presented herein. A. niger induced the hydroxylation of two pairs of curdione enantiomers, yielding the corresponding mirror-image hydroxylated curdiones. Simultaneously, the acid-mediated intramolecular "ene" rearrangements of these curdiones and hydroxylated curdione enantiomers yielded the corresponding mirror-image curcumalactones and hydroxylated curcumalactones. Among the 16 pairs of enantiomers obtained in this study, 23 compounds are new sesquiterpenoids. These curdione and curcumalactone derivatives are of particular interest, as they have the potential to be used as lead compounds and scaffolds in drug discovery. PMID:25679443

    The aim of this study was to evaluate the oral absorption of two chemicals simultaneously using a drug dissolution/absorption simulating system (DDASS), and to establish a correlation between DDASS and in vivo absorption to clarify the prediction of this in vitro model. Ferulic acid (FA) and tetrahydropalmatine (THP), the components of Angelicae Sinensis Radix and Corydalis Yanhusuo Rhizoma, respectively, were chosen as model compounds. Three groups including FA, THP, and FA and THP together (FA + THP) were studied in DDASS. The corresponding in vivo pharmacokinetics study was performed in rats. Then the correlation was analysed between DDASS permeation in vitro and rat absorption data in vivo. A strong level A correlation (r > 0.84) was obtained after a correlation coefficient test (p < 0.05 or 0.01). Moreover, when FA and THP were used together in DDASS, the cumulative permeation of FA increased by 38.5%, while THP permeation decreased by 25.8%. In rats, the area under the concentration-time curve from time to infinity for FA increased 2.6-fold, while THP decreased 19.6%. The changes in rat intestinal permeation modeled by the DDASS were consistent with the absorption changes in rats. We conclude that DDASS is a valid in vitro model to evaluate oral absorption of two drug components simultaneously and reflect the in vivo characteristics of drug absorption accurately.

Maxim roots (Radix Peucedani), Momordica cochinchinensis Spreng. seeds (Semen Momordicae), and Bupleurum chinense DC. roots (Radix Bupleuri chinensis) for their in vivo anthelmintic activity against monogenean Dactylogyrus intermedius in goldfish (Carassius auratus). The results showed that the efficacies of methanol, chloroform, and ethyl acetate extracts from R. Bupleuri chinensis were found to be, in this order, more effective than others with the 48 h-EC(50) and EC(90) values of 3.5 and 6.9, 6.0 and 8.4, 7.4 and 11.2 mg/L, respectively, followed by ethyl acetate extract of R. cimicifugae and chloroform extract of R. peucedani with EC(50) 189.2 and 240.4 mg/L. The promising methanol, chloroform, and ethyl acetate extracts from R. Bupleuri chinensis were subjected to acute toxicity tests for the evaluation of their safety to the host. After 48-h exposure, the mortalities of goldfish were recorded, and the established LC(50) values were 10.1-, 4.2-, and 8.4-fold higher than the corresponding EC(50). These results indicated that the three extracts from R. Bupleuri chinensis exhibit potential to be used as preferred natural antiparasitics for the control of the D. intermedius, especially for the methanolic one. PMID:21153837

    Yu Ping Feng San (YPFS), a Chinese herbal decoction comprising Astragali Radix (AR; Huangqi), Atractylodis Macrocephalae Rhizoma (AMR; Baizhu), and Saposhnikoviae Radix (SR; Fangfeng), has been used clinically to treat inflammatory bowel diseases (IBD). Previously, we demonstrated a dual role of YPFS in regulating cytokine release in cultured macrophages. In this study, we elucidated the anti-inflammatory effect of YPFS that is mediated through modulating the expression of three key enzymes involved in IBD: inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and intestinal alkaline phosphatase (IALP). In a lipopolysaccharide (LPS)-induced chronic-inflammation model of cultured murine macrophages, YPFS treatment suppressed the activation of iNOS and COX-2 expression in a dose-dependent manner. Conversely, application of YPFS in cultured small intestinal enterocytes markedly induced the expression of IALP in a time-dependent manner, which might strengthen the intestinal detoxification system. A duality of YPFS in modulating the expression of iNOS and COX-2 was determined here. The expression of iNOS and COX-2 in macrophages was induced by YPFS, and this activation was partially blocked by the NF-κB-specific inhibitor BAY 11-7082, indicating a role of NF-κB signaling. These YPFS-induced changes in gene regulation strongly suggest that the anti-inflammatory effects of YPFS are mediated through the regulation of inflammatory enzymes. PMID:24967898

    Curcumol, isolated from the traditional medical plant Rhizoma Curcumae, is the bioactive component of Zedoary oil, whose potential anti-tumor effect has attracted considerable attention in recent years. Though many researchers have reported curcumol and its bioactivity, the potential molecular mechanism for its anti-cancer effect in colorectal cancer LoVo cells still remains unclear. In the present study, we found that curcumol showed growth inhibition and induced apoptosis of LoVo cells in a dose- and time-dependent manner. The occurrence of its proliferation inhibition and apoptosis came with suppression of IGF-1R expression, and then increased the phosphorylation of p38 mitogen activated protein kinase (MAPK), which might result in a cascade response by inhibiting the CREB survival pathway and finally triggered Bax/Bcl-2 and poly(ADP-ribose) polymerase 1 (PARP-1) apoptosis signals. Moreover, curcumol inhibited colorectal cancer in xenograft models of nude mice. Immunohistochemical and Western blot analysis revealed that curcumol could decrease the expression of ki-67, Bcl-2 as well as CREB1, and increase the expression of Bax and the phosphorylation of p38, which were consistent with our in vitro study. Overall, our in vitro and in vivo data confirmed the anti-cancer activity of curcumol, which was related to a significant inhibition of IGF-1R and activation of p38 MAPKs, indicating that curcumol may be a potential anti-tumor agent for colorectal carcinoma therapy.

However, currently there are still no effective and widely applicable pharmacotherapies for migraine patients. Herbal formulae, characterized as multiple herbs, constituents and targets, have been acknowledged with clinical effects in treating migraine, which attract more and more researchers' attention although their exact molecular mechanisms are still unclear. In this work, a novel systems pharmacology-based method which integrates pharmacokinetic filtering, target fishing and network analysis was developed and exemplified by a probe, i.e. Tianshu formula, a widely clinically used anti-migraine herbal formula in China which comprises of Rhizoma chuanxiong and Gastrodia elata. The results exhibit that 20 active ingredients of Tianshu formula possess favorable pharmacokinetic profiles, which have interactions with 48 migraine-related targets to provide potential synergistic therapeutic effects. Additionally, from systematic analysis, we speculate that R. chuanxiong as the monarch herb mediates the major targets like PTGS2, ESR1, NOS2, HTR1B and NOS3 to regulate the vascular and nervous systems, as well as the inflammation and pain-related pathways to benefit migraine patients. Meanwhile, as an adjuvant herb, G. elata may not only assist the monarch herb to improve the outcome of migraine patients, but also regulate multiple targets like ABAT, HTR1D, ALOX15 and KCND3 to modify migraine accompanying symptoms like vomiting, vertigo and gastrointestinal disorders.

    Pinelliae rhizoma is the dried tuber of Pinellia ternata (Thunb.) Breit., and has been used for thousands of years as a traditional Chinese medicine. However, its genomic background is little known. With the development of high-throughput genomic sequencing, it is now easy and cheap to obtain genomic information. In this study, 193,032,910 high-quality clean reads were generated using the Illumina Hiseq 2000 platform. A total of 53,544 unigenes were identified from the contigs assembled. Functional annotation analysis annotated 37,318, 27,697, 23,043, 22,869, 23,328, and 27,415 unigenes. KEGG analysis revealed that five pathways (169 genes) were associated with alkaloid synthesis, 201 unigenes were related to fatty acid biosynthesis (ko00061), and 133 unigenes were involved in the biosynthesis of unsaturated fatty acids (ko01040). In addition, 6703 simple sequence repeats were designed based on the unigene sequences for screening germplasm resources in the future. These data are a valuable resource for genomic studies on Pinellia plants.

    Novel open-tubular capillary electrochromatography (OT-CEC) systems with core/shell magnetic nanoparticles modified by amino or C18 groups as stationary phase were constructed by immobilizing nanoparticles in the capillary with permanent magnets. Influence of preparation method of OT-CEC column with series stationary phases (continuous two-dimension) on column performance and effect of dispersant on capability of OT-CEC column prepared by stationary phases with mixed functionalities (mixed stationary phases) were investigated in details to achieve stable preparation. Organic acids were used to evaluate the OT-CEC systems, and the relative column efficiency of salicylic acid was 420,000 plates/m for series stationary phases, while that of benzoic acid reached 480,000 plates/m for mixed stationary phases. The excellent within-column and between-column repeatability (n=5) testified with the RSDs of retention time were less than 0.44% and 10.20% for series stationary phases and 1.65% and 4.29% for mixed stationary phases. The two OT-CEC systems were further applied to separation of the aqueous extract of Rhizoma gastrodiae. Comparing with normal OT capillary column, the new systems show extra high column efficiency due to large surface areas of nanoparticles and multiple separation mechanisms, and they have great potential in the method development for the analysis of complicated samples.

    Aim. The incidence of diabetic osteoporosis (DOP) is increasing due to lack of effective management over the past few decades. This review aims to summarize traditional Chinese medicine (TCM) suitability in the pathogenesis and clinical and preclinical management of DOP. Methods. Literature sources used were from Medline (Pubmed), CNKI (China Knowledge Resource Integrated Database), and CSTJ (China Science and Technology Journal Database) online databases. For the consultation, keywords such as diabetic osteoporosis (DOP), TCM, clinical study, animal experiment, toxicity, and research progress were used in various combinations. Around 100 research papers and reviews were visited. Results. Liver-spleen-kidney insufficiency may result in development of DOP. 18 clinical trials are identified to use TCM compound prescriptions for management of patients with DOP. TCM herbs and their active ingredients are effective in preventing the development of DOP in streptozotocin (STZ) and alloxan as well as STZ combined with ovariectomy insulted rats. Among them, most frequently used TCM herbs in clinical trials are Radix Astragali, Radix et Rhizoma Salviae Miltiorrhizae, Radix Rehmanniae Preparata, and Herba Epimedii. Some of TCM herbs also exhibit toxicities in clinical and preclinical research. Conclusions. TCM herbs may act as the novel sources of anti-DOP drugs by improving bone and glucolipid metabolisms. However, the pathogenesis of DOP and the material base of TCM herbs still merit further study.

    Rhizoma Atractylodes macrocephala polysaccharides (RAMP) have been reported to have a variety of important biological activities. In this study, an ultrasonic-assisted enzymatic extraction (UAEE) was employed to obtain the highest extraction yield and strongest antioxidant activity of RAMP and optimized by a multi-response optimization process. A three-level four-factor Box-Behnken design (BBD) was performed as response surface methodology (RSM) with desirability function (DF) to attain the optimal extraction parameters. The DPPH scavenging percentage was used to represent the antioxidant ability of RAMP. The maximum D value (0.328), along with the maximum yield (59.92%) and DPPH scavenging percentage (13.28%) were achieved at 90.54 min, 57.99 °C, 1.95% cellulase and 225.29 W. These values were further validated and found to be in good agreement with the predicted values. Compared to the other extraction methods, both the yield and scavenging percentage of RAMP obtained by UAEE was favorable and the method appeared to be time-saving and of high efficiency. These results demostrated that UAEE is an appropriate and effective extraction technique. Moreover, RSM with DF approach has been proved to be adequate for the design and optimization of the extraction parameters for RAMP. This work has a wide range of implications for the design and operation of polysaccharide extraction processes.

    Berberine is an isoquinoline alkaloid found in Rhizoma coptidis, and elicits anti-inflammatory effects through diverse mechanisms. Based on previous reports that activating transcription factor-3 (ATF-3) acts as a negative regulator of LPS signaling, the authors investigated the possible involvement of ATF-3 in the anti-inflammatory effects of berberine. It was found berberine concentration-dependently induced the expressions of ATF-3 at the mRNA and protein levels and concomitantly suppressed the LPS-induced productions of proinflammatory cytokines (TNF-α, IL-6, and IL-1β). In addition, ATF-3 knockdown abolished the inhibitory effects of berberine on LPS-induced proinflammatory cytokine production, and prevented the berberine-induced suppression of MAPK phosphorylation, but had little effect on AMPK phosphorylation. On the other hand, the effects of berberine, that is, ATF-3 induction, proinflammatory cytokine inhibition, and MAPK inactivation, were prevented by AMPK knockdown, suggesting ATF-3 induction occurs downstream of AMPK activation. The in vivo administration of berberine to mice with LPS-induced endotoxemia increased ATF-3 expression and AMPK phosphorylation in spleen and lung tissues, and concomitantly reduced the plasma and tissue levels of proinflammatory cytokines. These results suggest berberine has an anti-inflammatory effect on macrophages and that this effect is attributable, at least in part, to pathways involving AMPK activation and ATF-3 induction.

    This study examined the composition of over-the-counter (OTC) sleeping pills in Hong Kong and reviewed the current knowledge about the hypnotic efficacy and safety of their major herbal and dietary supplement constituents. We conducted a cross-sectional survey of OTC sleep aids at drug stores in a residential district of 0.3 million population and literature search using MEDLINE, EMBASE, PsycINFO, China Journal Net, China Biomedical Database and relevant English and Chinese literature. We identified 17 brands of OTC sleeping pill: eleven of them were composed of mixtures of Chinese and Western herbal agents and six brands contained 3 mg of melatonin. The Chinese herbal mixture suanzaorentang, comprising zizyphi spinosi semen, poria cocos, ligusticum wallichii, anemarrhenae rhizoma and glycyrrhizae radix in ratio of 7:5:2:1:1, was the most common OTC sleeping pill available in the survey. Our literature review showed that kava, valerian and melatonin were the better-researched herbs and dietary supplements, however, the data on hypnotic efficacy and safety was inadequate to support their clinical use. More rigorous investigations of the risk-benefit relationship of herbal agents and dietary supplements used for insomnia are needed. PMID:12490346

    Berberine, one of the major constituents of Chinese herb Rhizoma coptidis, has been demonstrated to lower blood glucose, blood lipid, and body weight in patients with type 2 diabetes mellitus. The anti-obesity effect of berberine has been attributed to its anti-adipogenic activity. However, the underlying molecular mechanism remains largely unknown. In the present study, we found that berberine significantly suppressed the expressions of CCAAT/enhancer-binding protein (C/EBP)α, peroxisome proliferators-activated receptor γ2 (PPARγ2), and other adipogenic genes in the process of adipogenesis. Berberine decreased cAMP-response element-binding protein (CREB) phosphorylation and C/EBPβ expression at the early stage of 3T3-L1 preadipocyte differentiation. In addition, CREB phosphorylation and C/EBPβ expression induced by 3-isobutyl-1-methylxanthine (IBMX) and forskolin were also attenuated by berberine. The binding activities of cAMP responsive element (CRE) stimulated by IBMX and forskolin were inhibited by berberine. The binding of phosphorylated CREB to the promoter of C/EBPβ was abrogated by berberine after the induction of preadipocyte differentiation. These results suggest that berberine blocks adipogenesis mainly via suppressing CREB activity, which leads to a decrease in C/EBPβ-triggered transcriptional cascades. PMID:25928058

    Curcumin, a type of natural active ingredient, is derived from rhizoma of Curcuma, which possesses antioxidant, antitumorigenic and anti-inflammatory activities. The present study aimed to investigate whether treatment with curcumin reduced high-fat diet (HFD)-induced spermatogenesis dysfunction. Sprague-Dawley rats fed a HFD were treated with or without curcumin for 8 weeks. The testis/body weight, histological analysis and serum hormone levels were used to evaluate the effects of curcumin treatment on spermatogenesis dysfunction induced by the HFD. In addition, the expression levels of apoptosis associated proteins, Fas, B-cell lymphoma (Bcl)-xl, Bcl-associated X protein (Bax) and cleaved-caspase 3, were determined in the testis. The results of the present study suggested that curcumin treatment attenuated decreased testis/body weight and abnormal hormone levels. Morphological changes induced by a HFD were characterized as atrophied seminiferous tubules, decreased spermatogenetic cells and interstitial cells were improved by curcumin treatment. In addition, curcumin treatment reduced apoptosis in the testis, and decreased expression of Fas, Bax and cleaved-caspase 3, as well as increased expression of Bcl-xl. In conclusion, the present study revealed that curcumin treatment reduced HFD-induced spermatogenesis dysfunction in male rats. PMID:27600729

    Hormesis is a phenomenon of biphasic dose response characterized by exhibiting stimulatory or beneficial effects at low doses and inhibitory or toxic effects at high doses. Increasing numbers of chemicals of various types have been shown to induce apparent hormetic effect on cancer cells. However, the underlying significance and mechanisms remain to be elucidated. Berberine, one of the major active components of Rhizoma coptidis, has been manifested with notable anticancer activities. This study aims to investigate the hormetic effect of berberine and its influence on the anticancer activities of chemotherapeutic agents. Our results demonstrated that berberine at low dose range (1.25 ~ 5 μM) promoted cell proliferation to 112% ~170% of the untreated control in various cancer cells, while berberine at high dose rage (10 ~ 80 μM) inhibited cell proliferation. Further, we observed that co-treatment with low dose berberine could significantly attenuate the anticancer activity of chemotherapeutic agents, including fluorouracil (5-FU), camptothecin (CPT), and paclitaxel (TAX). The hormetic effect and thereby the attenuated anticancer activity of chemotherapeutic drugs by berberine may attributable to the activated protective stress response in cancer cells triggered by berberine, as evidenced by up-regulated MAPK/ERK1/2 and PI3K/AKT signaling pathways. These results provided important information to understand the potential side effects of hormesis, and suggested cautious application of natural compounds and relevant herbs in adjuvant treatment of cancer.

    Ischemia/reperfusion (I/R)-induced autophagy increases the severity of cardiomyocyte injury. The aim of this study was to investigate the effects of berberine, a natural extract from Rhizoma coptidis, on the I/R-induced excessive autophagy in in vitro and in vivo models. Autophagy was increased both in H9c2 myocytes during hypoxia/reoxygenation (H/R) injury and in mouse hearts exposed to I/R. And the expression level of p-AMPK and p-mTORC2 (Ser2481) were increased during H/R period. In addition, the increased autophagy level was correlated with reduced cell survival in H9c2 myocytes and increased infarct size in mouse hearts. However, berberine treatment significantly enhanced the H/R-induced cell viability and reduced I/R-induced myocardial infarct size, which was accompanied by improved cardiac function. The beneficial effect of berberine is associated with inhibiting the cellular autophagy level, due to decreasing the expression level of autophagy-related proteins such as SIRT1, BNIP3, and Beclin-1. Furthermore, both the level of p-AMPK and p-mTORC2 (Ser2481) in H9c2 myocytes exposed to H/R were decreased by berberine. In summary, berberine protects myocytes during I/R injury through suppressing autophagy activation. Therefore, berberine may be a promising agent for treating I/R-induced cardiac myocyte injury.

    Berberine is an isoquinoline alkaloid found in several plant species like famous chinese herb, Rhizoma coptidis which has been used locally as a strong gastrointestinal remedy for thousands of years. The inhibitory effects of berberine on tumor progression properties have been reported before. In this study, we investigated the effect of berberine on an esophageal cancer cell line, KYSE-30 with emphasis on its effects on the expression of certain chemokine receptors. The cytotoxic effect of berberine on KYSE-30 cells was analyzed by MTT assay. In vitro cell migration assay was also applied to the treated cells and the expression levels of the selected chemokine receptors (CXCR4 and CCR7) was measured at mRNA level. A retarded growth, associated with increasing concentrations of berberine, was obvious. On the other hand, the migration rate of the cells was decreased when they were treated with different concentrations of berberine and the expression levels of the two chemokine receptors, involved in the migration and metastasis of esophageal cancer cells, were decreased following the same treatments. With these results, we tend to conclude that berberine might be a proper candidate for further investigations, by targeting the chemokine receptors, and possible applications as anti-metastatic agent in cancer studies.

    Tetrahydropalmatine (THP), with one chiral centre, is one of the major constituents of Rhizoma corydalis. THP is considered to possess analgesic, sedative, hypnotic actions and cardiac protection. The aim of this study was to elucidate the stereoselective interaction between THP and ABC transporters. The present study investigated three most important ABC transporters, including P-glycoprotein (P-gp), multidrug resistance protein 1 (MRP1) and breast cancer resistance protein (BCRP). The intracellular accumulation and bidirectional transport suggested THP enantiomers were inhibitors of P-gp, but not of MRP1 or BCRP. The IC(50) values of (-)-THP and (+)-THP on rhodamine 123 (P-gp substrate) efflux were 48.6 and 20.0 µM, respectively, which showed obvious stereoselective difference. In the bidirectional transport, THP enantiomers showed high passive permeability and the contribution of P-gp could not be testified. The western blot and real-time RT-PCR assays showed that THP enantiomers reduced the protein expression of P-gp, but did not affect its mRNA expression. In in vitro cytotoxicity test, THP enantiomers showed the potential of increasing the cytotoxicity of doxorubicin in P-gp-mediated multidrug resistant tumour cells. The present study showed the stereoselective interaction between THP enantiomers and P-gp, which should be considered in clinical practice. PMID:22900779

    Highlights: • Naringin possesses many pharmacological activities, promotes the proliferation of osteoblast. • Undecalcified histological obtain dynamic parameters of callus formation and remodeling. • Naringin regulate osteoclast apoptosis by mitochondrial pathway. - Abstract: Naringin, the primary active compound of the traditional Chinese medicine Rhizoma drynariae, possesses many pharmacological activities. The present study is an effort to explore the anti-osteoporosis potential of naringin in vivo and in vitro. In vivo, we used ovariectomized rats to clarify the mechanisms by which naringin anti-osteoporosis. In vitro, we used osteoclasts to investigate naringin promotes osteoclasts apoptosis. Naringin was effective at enhancing BMD, trabecular thickness, bone mineralization, and mechanical strength in a dose-dependent manner. The result of RT-PCR analysis revealed that naringin down-regulated the mRNA expression levels of BCL-2 and up-regulated BAX, caspase-3 and cytochrome C. In addition, naringin significantly reduced the bone resorption area in vitro. These findings suggest that naringin promotes the apoptosis of osteoclasts by regulating the activity of the mitochondrial apoptosis pathway and prevents OVX-induced osteoporosis in rats.

    Highlights: • Curcumol suppresses osteoclasts differentiation in vitro. • Curcumol impairs JNK/AP-1 signaling pathway. • Curcumol may be used for treating osteoclast related diseases. - Abstract: Osteoclasts, derived from hemopoietic progenitors of the monocyte/macrophage lineage, have a unique role in bone resorption, and are considered a potential therapeutic target in the treatment of such pathologic bone diseases as osteoporosis, rheumatoid arthritis, and periodontitis. In the present study, we demonstrate that curcumol, one of the major components of the essential oil of Rhizoma Curcumae, exhibits an inhibitory effect on receptor activator of nuclear factor kappaB ligand (RANKL)-induced osteoclast differentiation with both bone marrow-derived macrophages and RAW264.7 cells in a dose-dependent manner. In addition, RANKL-induced mRNA expression of osteoclast-specific genes, such as tartrate-resistant acid phosphatase, calcitonin receptor, and cathepsin K, is prominently reduced in the presence of curcumol. Furthermore, the molecular mechanism of action was investigated, and curcumol inhibited osteoclastogenesis by specifically impairing RANKL-induced c-Jun N-terminal kinase (JNK)/activator protein-1 (AP-1) signaling, which was further identified in rescue studies by means of anisomycin, a JNK signaling-specific activator. Taken together, these findings suggest that curcumol suppresses RANKL-induced osteoclast differentiation through the JNK/AP-1 signaling pathway, and may be useful as a therapeutic treatment for bone resorption-associated diseases.

    The effect of a new herbal composition, HemoHIM, on immune functions was examined in aged mice, in which various immune responses had been impaired. The composition HemoHIM was prepared by adding the ethanol-insoluble fraction to the total water extract of a mixture of three edible herbs, Angelica Radix, Cnidium Rhizoma and Paeonia Radix. Supplementation to the aged mice with HemoHIM restored the proliferative response and cytokine production of splenocytes with a response to ConA. Also, HemoHIM recovered the NK cell activity which had been impaired in the aged mice. Meanwhile aging is known to reduce the Th1-like function, but not the Th2-like function, resulting in a Th1/Th2 imbalance. HemoHIM restored the Th1/Th2 balance in the aged mice through enhanced IFN-gamma and IgG2a production, and conversely a reduced IL-4 and IgG1 production. It was found that one factor for the Th1/Th2 imbalance in the aged mice was a lower production of IL-12p70. However, HemoHIM restored the IL-12p70 production in the aged mice. These results suggested that HemoHIM was effective for the restoration of impaired immune functions of the aged mice and therefore could be a good recommendation for immune restoration in elderly humans.

    Although radiotherapy is commonly used for a variety of cancers, radiotherapy alone does not achieve a satisfactory therapeutic outcome. In this study, we examined the possibility that HemoHIM can enhance the anticancer effects of ionizing radiation (IR) in melanoma-bearing mice. The HemoHIM was prepared by adding the ethanol-insoluble fraction to the total water extract of a mixture of three edible herbs-Angelica Radix, Cnidium Rhizoma, and Paeonia Radix. Anticancer effects of HemoHIM were evaluated in melanoma-bearing mice exposed to IR. IR treatment (5 Gy at 7 days after melanoma cell injection) reduced the weight of the solid tumors, and HemoHIM supplementation with IR enhanced the decreases in tumor weight (P < .03). In the melanoma-bearing mice treated with IR, HemoHIM administration also increased the activity of natural killer cells and cytotoxic T cells, although the proportions of these cells in spleen were not different. In addition, HemoHIM administration increased the interleukin-2 and tumor necrosis factor-alpha secretion from lymphocytes stimulated with concanavalin A, which seemed to contribute to the enhanced efficacy of HemoHIM in tumor-bearing mice treated with IR. In conclusion, HemoHIM may be a beneficial supplement during radiotherapy for enhancing the antitumor efficacy. PMID:20136435

The effects of oil type and concentration, organic modifier, SDS, and buffer concentration on separation were examined in order to optimize the two methods. Oil contents and organic modifier were found to markedly influence the separation selectivity for both O/W and W/O systems. SDS concentration rarely affected separation resolution for O/W MEEKC, and separation of eight phenolic acids and five diterpenoids could be improved by changing the buffer concentration for W/O MEEKC. A highly efficient O/W MEEKC separation method, where the 13 compounds were separated with baseline resolution, was achieved by using a microemulsion solution of pH 8.0 containing 0.6% cyclohexane, 3.0% SDS, 6.0% 1-butanol, and 3.0% ACN. The W/O MEEKC was unable to resolve all the components. In addition, the analytic time in O/W MEEKC was shorter than that in W/O MEEKC. Finally, the developed O/W MEEKC method was successfully applied to determine analytic compounds in RRSM samples. PMID:18435496

    Dehydrocorydaline (DHC) is an alkaloidal component isolated from Rhizoma corydalis. Previous studies have shown that DHC has anti-inflammatory and anti-tumor effects and that it can protect the cardiovascular system. However, there are few studies of the antinociceptive effects of DHC in vivo. This study explored the antinociceptive effects and possible mechanisms of DHC in mice using two inflammatory pain models: the acetic acid-induced writhing test and the formalin paw test. The intraperitoneal administration of DHC (3.6, 6 or 10 mg/kg) showed a dose-dependent antinociceptive effect in the acetic acid-induced writhing test and significantly attenuated the formalin-induced pain responses in mice. The antinociceptive effects of DHC were not associated with changes in the locomotor activity or motor responses of animals, and no obvious acute or chronic toxic effects were observed in the mice. Furthermore, the use of naloxone confirmed the involvement of the opioid receptor in the central antinociceptive effects of DHC. DHC reduced formalin-induced paw edema, which indicated that DHC may produce an anti-inflammatory effect in the periphery. In the formalin test, DHC decreased the expression of caspase 6 (CASP6), TNF-α, IL-1β and IL-6 proteins in the spinal cord. These findings confirm that DHC has antinociceptive effects in mice.

    In the present study, an attempt has been made to petroleum ether, chloroform, ethyl acetate, methanol, and water extracts of Prunus amygdalus Batsch seeds (Semen amygdali), Cimicifuga foetida L. rhizomes (Rhizoma Cimicifugae), Peucedanum decursivum (Miq.) Maxim roots (Radix Peucedani), Momordica cochinchinensis Spreng. seeds (Semen Momordicae), and Bupleurum chinense DC. roots (Radix Bupleuri chinensis) for their in vivo anthelmintic activity against monogenean Dactylogyrus intermedius in goldfish (Carassius auratus). The results showed that the efficacies of methanol, chloroform, and ethyl acetate extracts from R. Bupleuri chinensis were found to be, in this order, more effective than others with the 48 h-EC(50) and EC(90) values of 3.5 and 6.9, 6.0 and 8.4, 7.4 and 11.2 mg/L, respectively, followed by ethyl acetate extract of R. cimicifugae and chloroform extract of R. peucedani with EC(50) 189.2 and 240.4 mg/L. The promising methanol, chloroform, and ethyl acetate extracts from R. Bupleuri chinensis were subjected to acute toxicity tests for the evaluation of their safety to the host. After 48-h exposure, the mortalities of goldfish were recorded, and the established LC(50) values were 10.1-, 4.2-, and 8.4-fold higher than the corresponding EC(50). These results indicated that the three extracts from R. Bupleuri chinensis exhibit potential to be used as preferred natural antiparasitics for the control of the D. intermedius, especially for the methanolic one.

    Si-Wu-Tang (SWT) is a decoction consisting of a mixture of ingredients of Rehmanniae Radix, Angelica Radix, Chuanxiong Rhizoma and Paeoniae Radix. As a traditional Chinese herbal decoction, SWT has been widely used for the treatment of diseases characterized as blood and/or energy deficit. The present study was performed to evaluate the effects of SWT on the different populations of circulating white blood cells (WBCs) and gastrointestinal changes in γ-ray irradiated mice. Female mice were treated daily with orally administered SWT seven days before irradiation, until one day before irradiation or until one day before sample collection. WBC counts were determined from peripheral blood samples taken from the mice at different times post-irradiation. Hematoxylin and eosin (H&E) staining, as well as immunohistochemical analysis of fibrinogen, were utilized to evaluate the effects of SWT in the intestines of mice after radiation exposure. The results of the present studies demonstrate that SWT has protective effects against radiation damage to circulating WBCs, specifically to lymphocytes, and to the gastrointestinal tract of the irradiated animals.

    Fo Shou San (FSS) is an ancient herbal decoction comprised of Chuanxiong Rhizoma (CR; Chuanxiong) and Angelicae Sinensis Radix (ASR; Danggui) in a ratio of 2∶3. Previous studies indicate that FSS promotes blood circulation and dissipates blood stasis, thus which is being used widely to treat vascular diseases. Here, we aim to determine the cellular mechanism for the vascular benefit of FSS. The treatment of FSS reversed homocysteine-induced impairment of acetylcholine (ACh)-evoked endothelium-dependent relaxation in aortic rings, isolated from rats. Like radical oxygen species (ROS) scavenger tempol, FSS attenuated homocysteine-stimulated ROS generation in cultured human umbilical vein endothelial cells (HUVECs), and it also stimulated the production of nitric oxide (NO) as measured by fluorescence dye and biochemical assay. In addition, the phosphorylation levels of both Akt kinase and endothelial NO synthases (eNOS) were markedly increased by FSS treatment, which was abolished by an Akt inhibitor triciribine. Likewise, triciribine reversed FSS-induced NO production in HUVECs. Finally, FSS elevated intracellular Ca2+ levels in HUVECs, and the Ca2+ chelator BAPTA-AM inhibited the FSS-stimulated eNOS phosphorylation. The present results show that this ancient herbal decoction benefits endothelial function through increased activity of Akt kinase and eNOS; this effect is causally via a rise of intracellular Ca2+ and a reduction of ROS.

    Investigation of the chemical constituents of Rhizoma Cyperi (Cyperus rotundus Linneus)resulted in the isolation of novel enantiomeric andmeso-stilbene trimers [i.e., (+)- and (−)-(E)-cyperusphenol A (1, 2 respectively) and (E)-mesocyperusphenol A (3)], a trimer bearing a novelhexacyclic ring system [cyperusphenol B (5)], aswell as knownstilbenoids (cyperusphenols C (4)and D (6), scirpusins A (7) and B (8), and piceid (9)) and luteolin. HPLC was used for the opticalresolution of 1 and 2 as well as for the identification of cooccurrence of enantiomers of 7. Thestructures of the isolates were established by spectroscopic analyses, including a detailed NMRspectroscopic investigation. The isolates were evaluated in terms of their antiproliferative activityemploying the Jurkat cell line (human T-cell leukemia cells), while the IC50 potencies of aracemate of 1 and 2, 3, 5, and 6 were estimated as 27.4, 40.5, 26.4, and 26.3 μM, respectively. Thesuppression of cell growth by 6 was due to the induction of apoptosis,whichwas characterized bynuclear changes and PARP-1 cleavage determined bywestern blotting.We also evaluated the freeradical scavenging activity of the isolates.

    Guizhi decoction (GZD), a well-known traditional Chinese medicine (TCM) prescription consisting of Ramulus Cinnamomi, Radix Paeoniae Alba, Radix Glycyrrhizae, Fructus Jujubae and Rhizoma Zingiberis Recens, is usually used for the treatment of common colds, influenza, and other pyretic conditions in the clinic. However, the absorbed ingredients and metabolic compounds of GZD have not been reported. In this paper, a method incorporating rapid resolution liquid chromatography (RRLC) with quadrupole-time-of-flight mass spectrometry (Q-TOF-MS) was used to identify ingredients after oral administration of GZD. Identification of the primary components in GZD, drug-containing serum and urine samples was carried out in order to investigate the assimilation and metabolites of the decoction in vivo. By comparing the total ion chromatograms (TICs) of GZD, a total of 71 constituents were detected or characterized. By comparing TICs of blank and dosed rat plasma, a total of 15 constituents were detected and identified as prototypes according to their retention time (tR) and MS, MS/MS data. Based on this, neutral loss scans of 80 and 176 Da in samples of rat plasma and urine helped us to identify most of the metabolites. Results showed that the predominant metabolic pathways of (epi) catechin and gallic acid were sulfation, methylation, glucuronidation and dehydroxylation; the major metabolic pathways of flavone were hydrolysis, sulfation and glucuronidation. Furthermore, degradation, oxidation and ring fission were found to often occur in the metabolism process of GZD in vivo. PMID:27626411

    The alkaline ethanol precipitation process is investigated as an example of a technique for the removal of tannins extracted from Salviae miltiorrhizae Radix et Rhizoma for the manufacture of Danshen injection. More than 90% of the tannins can be removed. However, the recoveries of danshensu, rosmarinic acid, and salvianolic acid B were less than 60%. Total tannin removal increased as the refrigeration temperature decreased or the amount of NaOH solution added increased. Phenolic compound recoveries increased as refrigeration temperature increased or the amount of NaOH solution added decreased. When operated at a low refrigeration temperature, a relative high separation selectivity can be realized. Phenolic compound losses and tannin removal were mainly caused by precipitation. The formation of phenol salts, whose solubility is small in the mixture of ethanol and water used, is probably the reason for the precipitation. A model considering dissociation equilibrium and dissolution equilibrium was established. Satisfactory correlation results were obtained for phenolic compound recoveries and total tannin removal. Two important parameters in the model, which are the water content and pH value of alkaline supernatant, are suggested to be monitored and controlled to obtain high batch-to-batch consistency.

    Yu Ping Feng San (YPFS), an ancient Chinese herbal decoction composed of Astragali Radix, Atractylodis Macrocephalae Rhizoma and Saposhnikoviae Radix, has been used in the clinic for treating immune deficiency. In cancer therapy, YPFS is being combined with chemotherapy drugs to achieve improved efficacy; however, scientific evidence to illustrate this combination effect is lacking. The present study aims to demonstrate the anti-drug resistance of YPFS in cisplatin (DDP)-resistant non-small cell lung cancer cells (A549/DDP). The application of YPFS exhibited a synergistic enhancement of DDP-induced cytotoxicity as well as of the apoptotic signalling molecules. DDP-induced expression of the multi-drug-resistance efflux transporters was markedly reduced in the presence of YPFS, resulting in a higher intracellular concentration of DDP. In addition, the application of YPFS increased DDP-induced ROS accumulation and MMP depletion, decreased p62/TRAF6 signalling in DDP-treated A549/DDP cells. The co-treatment of DDP and YPFS in tumour-bearing mice reduced the tumour size robustly (by more than 80%), which was much better than the effect of DDP alone. These results indicate that YPFS can notably improve the DDP-suppressed cancer effect, which may be a consequence of the elevation of intracellular DDP via the drug transporters as well as the down regulation of p62/TRAF6 signalling.

    Aim. The incidence of diabetic osteoporosis (DOP) is increasing due to lack of effective management over the past few decades. This review aims to summarize traditional Chinese medicine (TCM) suitability in the pathogenesis and clinical and preclinical management of DOP. Methods. Literature sources used were from Medline (Pubmed), CNKI (China Knowledge Resource Integrated Database), and CSTJ (China Science and Technology Journal Database) online databases. For the consultation, keywords such as diabetic osteoporosis (DOP), TCM, clinical study, animal experiment, toxicity, and research progress were used in various combinations. Around 100 research papers and reviews were visited. Results. Liver-spleen-kidney insufficiency may result in development of DOP. 18 clinical trials are identified to use TCM compound prescriptions for management of patients with DOP. TCM herbs and their active ingredients are effective in preventing the development of DOP in streptozotocin (STZ) and alloxan as well as STZ combined with ovariectomy insulted rats. Among them, most frequently used TCM herbs in clinical trials are Radix Astragali, Radix et Rhizoma Salviae Miltiorrhizae, Radix Rehmanniae Preparata, and Herba Epimedii. Some of TCM herbs also exhibit toxicities in clinical and preclinical research. Conclusions. TCM herbs may act as the novel sources of anti-DOP drugs by improving bone and glucolipid metabolisms. However, the pathogenesis of DOP and the material base of TCM herbs still merit further study. PMID:27698674

    To identify major active constituents and measure their levels in a typical medicinal herb–Rhizoma coptidis, we applied the concept of removing and adding, taking inspiration from functional genetic methods. As this herb has bacteriostatic properties and is used to treat bacterial diarrhea, we examined the effects of individual constituents (berberine, palmatine, coptisine, epiberberine, jateorrhizine and columbamine) on the growth of Shigella dysenteriae with microcalorimetry. The removing and adding procedures revealed that berberine and coptisine were the main antibacterial constituents of R. coptidis, with bacteriostatic activities of 54.10% and 39.75%, respectively. The relative levels of berberine and coptisine in R. coptidis were 8.08%–31.92% and 4.05%–14.45%, respectively. On the basis of whole effect, the method of constituents removing and adding, coupled with a bioassay, is a useful strategy to identify the active constituents and measure their levels in herbal medicines, which may provide reference to other natural products.

    Prolyl oligopeptidase is a cytosolic serine peptidase that hydrolyzes proline-containing peptides at the carboxy terminus. This peptidase has been associated with schizophrenia, bipolar affective disorder, and related neuropsychiatric disorders, and therefore may have important clinical implications. Among the strategies used to find novel prolyl oligopeptidase inhibitors, traditional Chinese medicinal plants provide a rich source of unexplored compounds. We used (19)F NMR spectroscopy to search for new prolyl oligopeptidase inhibitors in a library of traditional Chinese medicine plant extracts. Several extracts were identified as powerful inhibitors of this peptidase. The alkaloid berberine was the prolyl oligopeptidase inhibitory molecule isolated from Rhizoma coptidis extract. Berberine inhibited prolyl oligopeptidase in a dose-dependent manner. As berberine is a natural compound that has been safely administered to humans, it opens up new perspectives for the treatment of neuropsychiatric diseases. The results described herein suggest that the initiation of clinical trials in patients with schizophrenia, bipolar affective disorder, or related diseases in which cognitive capabilities are affected should be undertaken with either the extract or pure BBR.

    Song Bu Li decoction (SBL) is a traditional Uyghur medicinal herbal preparation, containing Nardostachyos Radix et Rhizoma. Recently, SBL is being used to treat neurological disorders (insomnia and neurasthenia) and heart disorders (arrhythmia and palpitation). Although this herbal extract has been used for many years, there is no scientific basis about its effectiveness. Here, we aimed to evaluate the protective and differentiating activities of SBL in cultured PC12 cells. The pretreatment of SBL protected the cell against tBHP-induced cell death in a dose-dependent manner. In parallel, SBL suppressed intracellular reactive oxygen species (ROS) formation. The transcriptional activity of antioxidant response element (ARE), as well as the key antioxidative stress proteins, was induced in dose-dependent manner by SBL in the cultures. In cultured PC12 cells, the expression of neurofilament, a protein marker for neuronal differentiation, was markedly induced by applied herbal extract. Moreover, the nerve growth factor- (NGF-) induced neurite outgrowth in cultured PC12 cells was significantly potentiated by the cotreatment of SBL. In accord, the expression of neurofilament was increased in the treatment of SBL. These results therefore suggested a possible role of SBL by its effect on neuron differentiation and protection against oxidative stress. PMID:24198845

    Due to the severe damage caused by free hydroxyl radicals (OH.) to cells and tissues, there is much interest in finding and studying effective and non-toxic OH. scavengers, including traditional Chinese herbs. In this paper, the simple and highly-sensitive technique of capillary zone electrophoresis with amperometric detection (CZE-AD) was used to study the OH. scavenging activities of aqueous extracts from some traditional Chinese herbs. Salicylic acid (SAL) was used as an OH. trap, and the content of OH. could be determined by assaying their products, 2,3-dihydroxybenzoic acid (2,3-DHBA) and 2,5-dihydroxybenzoic acid (2,5-DHBA). The optimum conditions for CZE-AD for the determination of 2,3-DHBA and 2,5-DHBA were explored. The linearity ranges of 2,3-DHBA and 2,5-DHBA were 1.0 x10(-7) approximately 1.0 x10(-4) mol L(-1), and their detection limits were as low as 2 x 10(-8) mol L(-1), which were much better than the CE-UV method often used. The traditional Chinese herbs studied included Radix angelicae sinensis, Rhizoma coptidis, Ligustrum lucidum, Ligusticum wallichii, Radices glycyrrhizae and Semen plantaginis. The experiments showed that the aqueous extracts from all of the above traditional Chinese herds had free OH. scavenging activities, although to different degrees. PMID:14985912

    Naringin is a major flavonoid found in grapefruit and is an active compound extracted from the Chinese herbal medicine Rhizoma Drynariae. Naringin is a potent stimulator of osteogenic differentiation and has potential application in preventing bone loss. However, the signaling pathway underlying its osteogenic effect remains unclear. We hypothesized that the osteogenic activity of naringin involves the Notch signaling pathway. Rat bone marrow stromal cells (BMSCs) were cultured in osteogenic medium containing-naringin, with or without DAPT (an inhibitor of Notch signaling), the effects on ALP activity, calcium deposits, osteogenic genes (ALP, BSP, and cbfa1), adipogenic maker gene PPARγ2 levels, and Notch expression were examined. We found that naringin dose-dependently increased ALP activity and Alizarin red S staining, and treatment at the optimal concentration (50 μg/mL) increased mRNA levels of osteogenic genes and Notch1 expression, while decreasing PPARγ2 mRNA levels. Furthermore, treatment with DAPT partly reversed effects of naringin on BMSCs, as judged by decreases in naringin-induced ALP activity, calcium deposits, and osteogenic genes expression, as well as upregulation of PPARγ2 mRNA levels. These results suggest that the osteogenic effect of naringin partly involves the Notch signaling pathway. PMID:27069482

According to the original description of Si Wu Tang, Angelica Sinensis Radix should be treated with wine. However, the importance of this wine-treated Angelica Sinensis Radix in Si Wu Tang's function has not been identified. In this article, the chemical and biological properties of two decoctions processed in different ways (Si Wu Tang with crude Angelica Sinensis Radix and Si Wu Tang with wine-treated Angelica Sinensis Radix) were compared for examination. The herbal decoction Si Wu Tang prepared from wine-treated Angelica Sinensis Radix contained much different amounts of its active compounds. Compared with Si Wu Tang using crude Angelica Sinensis Radix, Si Wu Tang prepared from wine-treated Angelica Sinensis Radix had better biological responses. Therefore, these findings accentuate the functional importance of herbs treated with wine in the Chinese decoction.

    This study investigated the preventive therapeutic effects of Hataedock (HTD) treatment on inflammatory regulation and skin protection in AD-induced NC/Nga mice under high-fat diet conditions. Before inducing AD, the extract of Coptidis Rhizoma and Glycyrrhiza uralensis was administered orally to the 3-week-old mice. After that, AD-like skin lesions were induced by applying DNFB. All groups except the control group were fed a high-fat diet freely. We identified the effects of HTD on morphological changes, cytokine release and the induction of apoptosis through histochemistry, immunohistochemistry, and TUNEL assay. HTD downregulated the levels of IL-4 and PKC but increased the levels of LXR. HTD also suppressed the mast cell degranulation and release of MMP-9, Substance P. The levels of TNF-α, p-IκB, iNOS, and COX-2 were also decreased. The upregulation of inflammatory cell's apoptosis is confirmed by our results as increase of apoptotic body and cleaved caspase-3 and decrease of Bcl-2. HTD also reduced edema, angiogenesis, and skin lesion inflammation. Our results indicate HTD suppresses various inflammatory response on AD-induced mice with obesity through the regulation of Th2 differentiation and the protection of lipid barrier. Therefore, HTD could be used as an alternative and preventive therapeutic approach in the management of AD. PMID:27313639

    The effect of a new herbal composition, HemoHIM, on immune functions was examined in aged mice, in which various immune responses had been impaired. The composition HemoHIM was prepared by adding the ethanol-insoluble fraction to the total water extract of a mixture of three edible herbs, Angelica Radix, Cnidium Rhizoma and Paeonia Radix. Supplementation to the aged mice with HemoHIM restored the proliferative response and cytokine production of splenocytes with a response to ConA. Also, HemoHIM recovered the NK cell activity which had been impaired in the aged mice. Meanwhile aging is known to reduce the Th1-like function, but not the Th2-like function, resulting in a Th1/Th2 imbalance. HemoHIM restored the Th1/Th2 balance in the aged mice through enhanced IFN-gamma and IgG2a production, and conversely a reduced IL-4 and IgG1 production. It was found that one factor for the Th1/Th2 imbalance in the aged mice was a lower production of IL-12p70. However, HemoHIM restored the IL-12p70 production in the aged mice. These results suggested that HemoHIM was effective for the restoration of impaired immune functions of the aged mice and therefore could be a good recommendation for immune restoration in elderly humans.

    Although radiotherapy is commonly used for a variety of cancers, radiotherapy alone does not achieve a satisfactory therapeutic outcome. In this study, we examined the possibility that HemoHIM can enhance the anticancer effects of ionizing radiation (IR) in melanoma-bearing mice. The HemoHIM was prepared by adding the ethanol-insoluble fraction to the total water extract of a mixture of three edible herbs-Angelica Radix, Cnidium Rhizoma, and Paeonia Radix. Anticancer effects of HemoHIM were evaluated in melanoma-bearing mice exposed to IR. IR treatment (5 Gy at 7 days after melanoma cell injection) reduced the weight of the solid tumors, and HemoHIM supplementation with IR enhanced the decreases in tumor weight (P < .03). In the melanoma-bearing mice treated with IR, HemoHIM administration also increased the activity of natural killer cells and cytotoxic T cells, although the proportions of these cells in spleen were not different. In addition, HemoHIM administration increased the interleukin-2 and tumor necrosis factor-alpha secretion from lymphocytes stimulated with concanavalin A, which seemed to contribute to the enhanced efficacy of HemoHIM in tumor-bearing mice treated with IR. In conclusion, HemoHIM may be a beneficial supplement during radiotherapy for enhancing the antitumor efficacy.

    The sesquiterpenoid curdione is one of the main bioactive components in the essential oil of Rhizoma Curcumae (Curcuma wenyujin, Curcuma phaeocaulis, and Curcuma kwangsiensis), which has been clinically used for the treatment of cancer in mainland China. Recently it was reported that natural curdione could be hydroxylated by Aspergillus niger and transferred to its corresponding curcumalactones under acidic conditions. Based on this study, the development of a sesquiterpenoid library through the "mirror-image" manipulation of bioactive (non)natural curdione scaffolds by chemical and biological approaches is presented herein. A. niger induced the hydroxylation of two pairs of curdione enantiomers, yielding the corresponding mirror-image hydroxylated curdiones. Simultaneously, the acid-mediated intramolecular "ene" rearrangements of these curdiones and hydroxylated curdione enantiomers yielded the corresponding mirror-image curcumalactones and hydroxylated curcumalactones. Among the 16 pairs of enantiomers obtained in this study, 23 compounds are new sesquiterpenoids. These curdione and curcumalactone derivatives are of particular interest, as they have the potential to be used as lead compounds and scaffolds in drug discovery.

    Furanodiene (FUR) is a natural terpenoid isolated from Rhizoma curcumae, a well-known Chinese medicinal herb that presents anti-proliferative activities in several cancer cell lines. Herein, we systematically investigated the effects of FUR on the significant processes of tumor progression with the relatively low concentrations in 95-D lung cancer cells. FUR concentration-dependently inhibited cell proliferation and blocked the cell cycle progressions in G1 phase by down-regulating the protein levels of cyclin D1 and CDK6, and up-regulating those of p21 and p27 in 95-D cells. FUR also affected the signaling molecules that regulate apoptosis in 95-D cells revealed by the down-regulation of the protein levels of full PARP, pro-caspase-7, survivin, and Bcl-2, and the up-regulation of cleaved PARP. Further studies showed that FUR enhanced the expression of light chain 3-II (LC3-II) in the protein level, indicating that autophagy is involved in this process. Besides, the adhesion ability of 95-D cells to matrigel and fibronectin was slightly inhibited after FUR treatment for 1 h in our experimental condition. FUR also slightly suppressed cell migration and invasion in 95-D cells according to the data from wound healing and Transwell assays, respectively. Taken together, FUR activated the signal molecules regulating G1 cell cycle arrest, apoptosis and autophagy, while slightly affecting the key steps of cell metastasis in 95-D lung cancer cells in the relatively low concentrations.

    Berberine is the major active component of Rhizoma Coptidis derived from a traditional Chinese herbal medicine and is known to regulate micro (mi)RNA levels, although the mechanism for this action remains unknown. The present study confirmed that treatment of 3T3‑L1 cells with berberine inhibited cell viability and differentiation in a dose‑ and time‑dependent manner, and significantly increased the mRNA expression levels of miRNA‑27a and miRNA‑27b. In addition, in 3T3‑L1 cells treated with berberine, overexpression of miRNA‑27a and miRNA‑27b improved the berberine-mediated inhibition of cell differentiation and reduction of triglyceride contents. By contrast, miRNA‑27a and miRNA‑27b inhibitors attenuated the berberine‑mediated inhibition of cell differentiation and reduction of triglyceride contents. Additionally, peroxisome proliferator‑activated receptors (PPAR)‑γ was confirmed to be a target of miRNA‑27a in the 3T3‑L1 cells. A dual‑luciferase reporter assay indicated that the expression of PPAR‑γ was negatively regulated by miRNA-27a. These findings may provide novel mechanistic insight into the antiobesity effects of certain compounds in traditional Chinese herbal medicine. PMID:27484069

    Berberine is an isoquinoline alkaloid found in Rhizoma coptidis, and elicits anti-inflammatory effects through diverse mechanisms. Based on previous reports that activating transcription factor-3 (ATF-3) acts as a negative regulator of LPS signaling, the authors investigated the possible involvement of ATF-3 in the anti-inflammatory effects of berberine. It was found berberine concentration-dependently induced the expressions of ATF-3 at the mRNA and protein levels and concomitantly suppressed the LPS-induced productions of proinflammatory cytokines (TNF-α, IL-6, and IL-1β). In addition, ATF-3 knockdown abolished the inhibitory effects of berberine on LPS-induced proinflammatory cytokine production, and prevented the berberine-induced suppression of MAPK phosphorylation, but had little effect on AMPK phosphorylation. On the other hand, the effects of berberine, that is, ATF-3 induction, proinflammatory cytokine inhibition, and MAPK inactivation, were prevented by AMPK knockdown, suggesting ATF-3 induction occurs downstream of AMPK activation. The in vivo administration of berberine to mice with LPS-induced endotoxemia increased ATF-3 expression and AMPK phosphorylation in spleen and lung tissues, and concomitantly reduced the plasma and tissue levels of proinflammatory cytokines. These results suggest berberine has an anti-inflammatory effect on macrophages and that this effect is attributable, at least in part, to pathways involving AMPK activation and ATF-3 induction.

    Rhizoma Atractylodes macrocephala polysaccharides (RAMP) have been reported to have a variety of important biological activities. In this study, an ultrasonic-assisted enzymatic extraction (UAEE) was employed to obtain the highest extraction yield and strongest antioxidant activity of RAMP and optimized by a multi-response optimization process. A three-level four-factor Box-Behnken design (BBD) was performed as response surface methodology (RSM) with desirability function (DF) to attain the optimal extraction parameters. The DPPH scavenging percentage was used to represent the antioxidant ability of RAMP. The maximum D value (0.328), along with the maximum yield (59.92%) and DPPH scavenging percentage (13.28%) were achieved at 90.54 min, 57.99 °C, 1.95% cellulase and 225.29 W. These values were further validated and found to be in good agreement with the predicted values. Compared to the other extraction methods, both the yield and scavenging percentage of RAMP obtained by UAEE was favorable and the method appeared to be time-saving and of high efficiency. These results demostrated that UAEE is an appropriate and effective extraction technique. Moreover, RSM with DF approach has been proved to be adequate for the design and optimization of the extraction parameters for RAMP. This work has a wide range of implications for the design and operation of polysaccharide extraction processes. PMID:26690404

    A new strategy for screening the crude natural extracts and quickly identifying the bioactive compounds was developed. In combination with high performance liquid chromatography-mass spectrometry (HPLC-MS) , the biologically active compounds, such as the enzyme i n the crude natural extract ca n be quickly identified by capillary electrophoresis (CE) -based activity assay. The crude natural extracts were assayed by a CE-based enzyme inhibitor screening method, and the active extract was isolated by HPLC-MS/MS with a semipreparative column. Then, each eluted component was assayed again with the CE-based assay method. Finally, the structures of the identified active compounds were elucidated by MS/MS analysis. Acetylcholinesterase ( ACHE), its substrate acetylthiocholine chloride ( AThCh), as well as the crude extract of Rhizoma coptidis were utilized for the proof of the methodology. Seven isoquinoline alkaloids, namely jatrorrhizine, epiberberine, columbamine, coptisine, corysamine, palmatine and berberine were identified to be active as the inhibitors of ACHE. Their IC50 values were 40, 442, 38, 182, 419, 54 and 16 micromol/L, respectively. Compared with the traditional screening methods, the method is characterized with several advantages, such as extremely low sample and reagent consumption, high speed of analysis, high sensitivity of detection, high throughput in terms of preparation of the natural products by HPLC. Overall, the results demonstrate that the method is valuable for the screening of the bioactive compounds in the crude natural extracts.

    Kouyanqing Granule (KYQG) is a traditional Chinese herbal formula composed of Flos lonicerae (FL), Radix scrophulariae (RS), Radix ophiopogonis (RO), Radix asparagi (RA), and Radix et rhizoma glycyrrhizae (RG). In contrast with the typical method of separating and then biologicalily testing the components individually, this study was designed to establish an approach in order to define the core bioactive ingredients of the anti-inflammatory effects of KYQG based on the relevance analysis between chemical characters and biological effects. Eleven KYQG samples with different ingredients were prepared by changing the ratios of the 5 herbs. Thirty-eight ingredients in KYQG were identified using Ultra-fast liquid chromatography-Diode array detector-Quadrupole-Time-of-flight-Tandem mass spectrometry (UFLC-DAD-Q-TOF-MS/MS) technology. Human oral keratinocytes (HOK) were cultured for 24 hours with 5% of Cigarette smoke extract (CSE) to induce inflammation stress. Interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumour necrosis factor-α (TNF-α) were evaluated after treatment with the eleven KYQG samples. Grey relational analysis(GRA), Pearson’s correlations (PCC), and partial least-squares (PLS) were utilized to evaluate the contribution of each ingredient. The results indicated that KYQG significantly reduced interleukin-1β, interleukin-6, interleukin-8, and tumour necrosis factor-α levels, in which lysine, γ-aminobutyric acid, chelidonic acid, tyrosine, harpagide, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isoquercitrin, luteolin-7-o-glucoside, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid, angoroside C, harpagoside, cinnamic acid, and ruscogenin play a vital role.

    Safrole-2',3'-oxide (SAFO) is a reactive electrophilic metabolite of the hepatocarcinogen safrole, the main component of sassafras oil. Safrole occurs naturally in a variety of spices and herbs, including the commonly used Chinese medicine Xi xin (Asari Radix et Rhizoma) and Dong quai (Angelica sinensis). SAFO is the most mutagenic metabolite of safrole tested in the Ames test. However, little or no data are available on the genotoxicity of SAFO in mammalian systems. In this study, we investigated the cytotoxicity and genotoxicity of SAFO in human HepG2 cells and male FVB mice. Using MTT assay, SAFO exhibited a dose- and time-dependent cytotoxic effect in HepG2 cells with TC(50) values of 361.9μM and 193.2μM after 24 and 48h exposure, respectively. In addition, treatment with SAFO at doses of 125μM and higher for 24h in HepG2 cells resulted in a 5.1-79.6-fold increase in mean Comet tail moment by the alkaline Comet assay and a 2.6-7.8-fold increase in the frequency of micronucleated binucleated cells by the cytokinesis-block micronucleus assay. Furthermore, repeated intraperitoneal administration of SAFO (15, 30, 45, and 60mg/kg) to mice every other day for a total of twelve doses caused a significant dose-dependent increase in mean Comet tail moment in peripheral blood leukocytes (13.3-43.4-fold) and in the frequency of micronucleated reticulocytes (1.5-5.8-fold). Repeated administration of SAFO (60mg/kg) to mice caused liver lesions manifested as a rim of ballooning degeneration of hepatocytes immediately surrounding the central vein. Our data clearly demonstrate that SAFO significantly induced cytotoxicity, DNA strand breaks, micronuclei formation both in human cells in vitro and in mice. More studies are needed to explore the role SAFO plays in safrole-induced genotoxicity.

    Nonalcoholic fatty liver disease (NAFLD), the hepatic manifestation of the metabolic syndrome, has become one of the most common causes of chronic liver disease over the last decade in developed countries. NAFLD includes a spectrum of pathological hepatic changes, such as steatosis, steatohepatitis, advanced fibrosis, and cirrhosis. Bisdemethoxycurcumin (BDMC) is polyphenolic compounds with a diarylheptanoid skeleton, curcumin close analogues, which is derived from the Curcumae Longae Rhizoma. While the rich bioavailability research of curcumin, BDMC is the poor studies. We investigated whether BDMC has the hepatoprotective effect and combinatory preventive effect with silymarin on methionine choline deficient (MCD)-diet-induced NAFLD in C57BL/6J mice. C57BL/6J mice were divided into five groups of normal (normal diet without any treatment), MCD diet (MCD diet only), MCD + silymarin (SIL) 100 mg/kg group, MCD + BDMC 100 mg/kg group, MCD + SIL 50 mg/kg + BDMC 50 mg/kg group. Body weight, liver weight, liver function tests, histological changes were assessed and quantitative real-time polymerase chain reaction and Western blot analyses were conducted after 4 weeks. Mice lost body weight on the MCD-diet, but BDMC did not lose less than the MCD-diet group. Liver weights decreased from BDMC, but they increased significantly in the MCD-diet groups. All liver function test values decreased from the MCD-diet, whereas those from the BDMC increased significantly. The MCD- diet induced severe hepatic fatty accumulation, but the fatty change was reduced in the BDMC. The BDMC showed an inhibitory effect on liver lipogenesis by reducing associated gene expression caused by the MCD-diet. In all experiments, the combinations of BDMC with SIL had a synergistic effect against MCD-diet models. In conclusion, our findings indicate that BDMC has a potential suppressive effect on NAFLD. Therefore, our data suggest that BDMC may act as a novel and potent therapeutic agent against NAFLD

    This study used a novel combination of in vivo and in vitro experiments to show that Braintone had neuroprotective effects and clarified the molecular mechanisms underlying its efficacy. The Chinese herbal extract Braintone is composed of Radix Rhodiolase Essence, Radix Notoginseng Essence, Folium Ginkgo Essence and Rhizoma Chuanxiong. In vivo experiments showed that cerebral infarction volume was reduced, hemispheric water content decreased, and neurological deficits were alleviated in a rat model of permanent middle cerebral artery occlusion after administration of 87.5, 175 or 350 mg/kg Braintone for 7 consecutive days. Western blot analysis showed that Braintone enhanced the expression of hypoxia-inducible factor 1α, heme oxygenase-1 and vascular endothelial growth factor in the ischemic cortex of these rats. The 350 mg/kg dose of Braintone produced the most dramatic effects. For the in vitro experiments, prior to oxygen-glucose deprivation, rats were intragastrically injected with 440, 880 or 1 760 mg/kg Braintone to prepare a Braintone-containing serum, which was used to pre-treat human umbilical vein endothelial cells for 24 hours. Human umbilical vein endothelial cell injury was alleviated with this pre-treatment. Western blot and real-time PCR analysis showed that the Braintone-containing serum increased the levels of hypoxia-inducible factor 1α mRNA and protein, heme oxygenase-1 protein and vascular endothelial growth factor mRNA in oxygen-glucose deprived human umbilical vein endothelial cells. The 1 760 mg/kg dose produced the greatest increases in expression. Collectively, these experimental findings suggest that Braintone has neuroprotective effects on ischemia-induced brain damage via the up-regulation of hypoxia-inducible factor 1α, heme oxygenase-1 and vascular endothelial growth factor expression in vascular endothelial cells.

    Paraquat poisoning causes multiple organ injury and high mortality due to severe toxicity and lack of effective treatment. Xuebijing (XBJ) injection, a traditional Chinese medicine preparation of five Chinese herbs (Radix Salviae Miltiorrhiae, Rhizoma Chuanxiong, Flos Carthami, Angelica Sinensis and Radix Paeoniae Rubra), has an anti-inflammatory effect and is widely used in the treatment of sepsis. This retrospective study was designed to evaluate the effects of XBJ combined with conventional therapy on mortality risk of patients with acute paraquat poisoning. Out of 68 patients, 27 were treated with conventional therapy (control group) and 41 were treated with intravenous administration of XBJ (100 ml, twice a day, up to 7 days) plus conventional therapy (XBJ group). Vital organ function, survival time within 28 days and adverse events during the treatment were reviewed. Results indicated that XBJ treatment significantly increased median survival time among patients ingesting 10-30 ml of paraquat (P=0.02) compared with the control group. After adjustment for covariates, XBJ treatment was associated significantly with a lower mortality risk (adjusted HR 0.242, 95% CI 0.113 to 0.516, P=0.001) compared with the control group. Additionally, compared with Day 1, on Day 3 the value of PaO2/FiO2 was significantly decreased, and the values of serum alanine aminotransferase, creatinine and troponin T were significantly increased in the control group (all P<0.05), but these values were significant improved in the XBJ group (all P<0.05). Only one patient had skin rash with itch within 30 minutes after injection and no severe adverse events were found in the XBJ group. In conclusion, XBJ treatment is associated with decreased mortality risk of patients with moderate paraquat poisoning, which may be attributed to improved function of vital organs with no severe adverse events.

    The present study is focused on the development of an analytical method for the simultaneous analysis of seventy-four pesticides belonging to different chemical classes (organochlorines, organophosphates, pyrethroids, dinitroanilines, dicarboximides, triazoles, etc.) in Chinese material medica. The samples were extracted according to the acetate QuEChERS protocol. To reduce the amount of co-extracted compounds, n-hexane instead of acetonitrile was employed as the extraction solvent. To improve the overall recoveries of problematic basic and base-sensitive compounds, sodium acetate was used to adjust the pH to a neutral condition, and florisil combined with octadecyl-modified silica (C18) were utilized in the cleanup step. The samples were analysed by GC-MS/MS, and quantified by matrix-matched calibration. The validation study was carried out on two representative herbs, Chuanxiong Rhizoma and Angelica Sinensis Radix. In two matrices, the linearity of the calibration was good between 5 and 250 ng/mL concentration ranges, and the limits of quantification (LOQs) less than 0.01 mg/kg for most pesticides. At the LOQs and ten times the LOQs, the mean recoveries of almost all pesticides were within 70-120%, with relative standard deviations (RSDs) lower than 10%. The method was applied on twenty real samples. Seven batches of Chuanxiong and five batches of Danggui were found to contain the residues. The combination of modified QuEChERS and GC-MS/MS offers low cost of analysis as well as excellent accuracy and sensitivity. This method could be especially useful for trace analysis of pesticide residues in complex matrices. PMID:26894850

    In the present review, the main objective was to report the incidence and causes of herbal medicines induced anticholinergic poisoning in Hong Kong during 1989-2012 and to emphasize the importance of pharmacovigilance, investigations and preventive measures. Relevant papers, official figures and unpublished data were obtained from Medline search, the Department of Health and the Drug and Poisons Information Bureau. In the New Territories East (where ~20% of the Hong Kong population lived), the incidence of herbal medicines induced anticholinergic poisoning during 1989-1993 was 0.09 per 100,000 population. There were no confirmed cases during 1994-1996. In the whole of Hong Kong, the incidence during 2000-June 2005 was 0.03 per 100,000 population. Contamination of Rhizoma Atractylodis (50%) and erroneous substitution (42%) were the main causes. The incidence during 2008-2012 was 0.06 per 100,000 population. Contamination of non-toxic herbs (50%) and erroneous substitution (41%) were the main causes. In Hong Kong, contamination of non-toxic herbs by tropane alkaloids and substitution of Flos Campsis by toxic Flos Daturae Metelis were the predominant causes of herbal medicines induced anticholinergic poisoning. Systematic studies along the supply chain are necessary to identify the likely sources of contamination. If erroneous substitution of Flos Campsis by Flos Daturae Metelis could be prevented, 40% of herbal medicines induced anticholinergic poisoning would not have occurred. Regular inspection of the retailer, continuing education for the staff in the herbal trade and repeated publicity measures will also be required. Pharmacovigilance of herbal medicines should help determine the incidence and causes of adverse reactions and monitor the effectiveness of preventive measures. PMID:26999208

    Mitochondria are an important intracellular pharmacological target because damage to this organelle results in a variety of human disorders and because mitochondria are involved in complex processes such as energy generation, apoptosis and lipid metabolism. To expedite the search for natural bioactive compounds targeting mitochondria, we initially developed an efficient mitochondria-based screening method by combining centrifugal ultrafiltration (CU) with liquid chromatography/mass spectrometry (LC/MS), which is called screening method for mitochondria-targeted bioactive constituents (SM-MBC) and is compatible with the search of mitochondria-targeted compounds from complex matrixes such as herbal medicines extracts. Functionally active, structurally intact and pure mitochondria were obtained from rat myocardium using an optimized protocol for mitochondrial isolation comprising organelle release followed by differential and Nycodenz density gradient centrifugation. After evaluating the reliability of the method using thiabendazole (TZ), rotenone (RN), amiodarone (AR) and trimetazidine (TD) as positive controls, this method was successfully applied to screen bioactive constituents from extracts of Polygoni Cuspidati Rhizoma et Radix (PCRR) and Scutellariae Radix (SR). Nineteen active compounds were detected and identified by LC/MS, of which 17 were new mitochondria-targeted compounds. The activity of 9 of the 19 hit compounds was confirmed by in vitro pharmacological trials. These results demonstrate that SM-MBC can be used for the efficient screening of mitochondria-targeted constituents in complex preparations used to treat mitochondrial disorders, such as PCRR and SR. The results may be meaningful for an in-depth understanding of drug mechanism of action and drug discovery from medicinal herbs.

    Current work was conducted to evaluate the cholesterol-lowering effect of coptisine extracted from Rhizoma coptidis in Syrian golden hamsters. The safety results indicated that coptisine was a safe and low-toxic compound. Coptisine showed a beneficial effect in the abnormal serum lipid levels induced by a high-fat and high-cholesterol diet (HFHC): at a concentration of 70.05 mg/kg, coptisine significantly led to a decrease in total cholesterol, triglycerides, and low-density lipoprotein cholesterol (LDL-c) levels by 26.70, 15.38, and 22.22 %, respectively, and high-density lipoprotein cholesterol (HDL-c) was increased by 41.74 % in serum of hamsters (p < 0.01). In addition, total bile acid (TBA) levels in feces of hamsters were elevated after coptisine administration. Further investigation has suggested that the mRNA and protein expression of 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMGCR) in the liver of hamsters was down-regulated by high-dosage coptisine treatment (p < 0.05); mRNA and protein expression of low-density lipoprotein receptor (LDLR) and cholesterol 7α-hydroxylase (CYP7A1) were dramatically up-regulated by coptisine administration. The apical sodium-dependent bile salt transporter expression was down-regulated in the coptisine-treated animals, but showed no significant differences from the HFHC groups. Taken together, our results demonstrate that a high dosage of coptisine could inhibit cholesterol synthesis via suppressing the HMGCR expression and promoting the use and excretion of cholesterol via up-regulating LDLR and CYP7A1 expression. These findings suggest a critical role for coptisine in anti- hypercholesterolemia, and thus it needs to be considered as a potential natural cholesterol lowering agent.

    Aromatase inhibitors (AIs) are widely used in the treatment of hormone‑dependent breast cancer and as a result, aromatase inhibitor‑associated bone loss (AIBL) has become a major concern amongst patients receiving AI treatment. Modified Shu‑Gan‑Liang‑Xue decoction (mSGLXD), a clinical prescription, has been used for ameliorating AIBL in patients with breast cancer for decades and has achieved good clinical efficacy. However, the mechanism underlying how mSGLXD influences bone homeostasis and alleviates AIBL has remained elusive. In the present study, mSGLXD was supplemented with Rhizoma Drynariae containing phytoestrogens, and the safety of mSGLXD was evaluated. mSGLXD did not possess estrogenic activity and significantly inhibited the proliferation of estrogen receptor‑positive breast cancer cell line MCF‑7, which suggested that mSGLXD was safe for postmenopausal patients with breast cancer. Subsequently, the effects of mSGLXD alone or in combination with anastrozole on osteoblastic MC3T3‑E1 cell proliferation and differentiation were investigated. Cell counting kit‑8, reverse transcription‑polymerase chain reaction and biochemical methods, such as ELISA and alizarin red S staining, were used in the present study. It was revealed that mSGLXD not only stimulated MC3T3‑E1 cell proliferation, but also upregulated alkaline phosphatase and osteocalcin gene and protein expression levels. High concentrations of anastrozole (10 or 100 µmol/l) markedly inhibited MC3T3‑E1 cell proliferation, but this inhibitory effect was attenuated by mSGLXD. Furthermore, mSGLXD increased MC3T3‑E1 cell mineralization following β‑glycerophosphate and ascorbic acid induction. Therefore, the results of the present study suggested that mSGLXD may be a promising adjuvant therapy, with high safety and efficacy, for the prevention and treatment of AIBL in patients with breast cancer who receive AI treatment.

    Migraine is a highly prevalent neurovascular disorder in the brain. An optimal therapy for migraine has not yet been developed. Gastrodin (Gas), the main effective constitute from Gastrodiae Rhizoma (Tianma in Chinese), has been indicated for migraine treatment and prophylaxis more than 30 years, with demonstrated safety. However, Gas is a phenolic glycoside, with relatively low concentrations and weak efficacy in the central nervous system. To develop more effective anti-migraine agents, we synthesized a novel Gas derivative (Gas-D). In the present study, comparative pharmacodynamic evaluations of Gas and Gas-D were performed in a model of nitroglycerin (NTG)-induced migraine in rats and the hot-plate test in mice. Following behavioral testing in this migraine model, external jugular vein blood and the trigeminal nucleus caudalis (TNC) were collected to analyze plasma nitric oxide (NO) and calcitonin gene-related peptide (CGRP) concentrations and c-Fos expression in the TNC. The acute oral toxicity of Gas and Gas-D was also examined. We found that Gas-D had potent anti-migraine effects, likely attributable to inhibition of both trigeminal nerve activation at central sites and the peripheral release of CGRP following NO scavenging. Additionally, Gas-D exerted significant anti-nociceptive effect in response to thermal pain compared with Gas. Furthermore, a single dose of 2.048 g/kg Gas or Gas-D presented no acute oral toxicity in mice. Altogether, the potent anti-migraine and anti-hyperalgesic effects of Gas-D suggest that it might be a potentially novel drug candidate for migraine treatment or prophylaxis. PMID:26704993

    Atopic dermatitis (AD) is a common allergic skin disease, characterized by dryness, itchiness, thickening and inflammation of the skin. Infiltration of eosinophils into the dermal layer and presence of edema are typical characteristics in the skin biopsy of AD patients. Previous in vitro and clinical studies showed that the Pentaherbs formula (PHF) consisting of five traditional Chinese herbal medicines, Flos Lonicerae, Herba Menthae, Cortex Phellodendri, Cortex Moutan and Rhizoma Atractylodis at w/w ratio of 2:1:2:2:2 exhibited therapeutic potential in treating AD. In this study, an in vivo murine model with oxazolone (OXA)-mediated dermatitis was used to elucidate the efficacy of PHF. Active ingredients of PHF water extract were also identified and quantified, and their in vitro anti-inflammatory activities on pruritogenic cytokine IL-31- and alarmin IL-33-activated human eosinophils and dermal fibroblasts were evaluated. Ear swelling, epidermis thickening and eosinophils infiltration in epidermal and dermal layers, and the release of serum IL-12 of the murine OXA-mediated dermatitis were significantly reduced upon oral or topical treatment with PHF (all p < 0.05). Gallic acid, chlorogenic acid and berberine contents (w/w) in PHF were found to be 0.479%, 1.201% and 0.022%, respectively. Gallic acid and chlorogenic acid could suppress the release of pro-inflammatory cytokine IL-6 and chemokine CCL7 and CXCL8, respectively, in IL-31- and IL-33-treated eosinophils-dermal fibroblasts co-culture; while berberine could suppress the release of IL-6, CXCL8, CCL2 and CCL7 in the eosinophil culture and eosinophils-dermal fibroblasts co-culture (all p < 0.05). These findings suggest that PHF can ameliorate allergic inflammation and attenuate the activation of eosinophils.

    Although antidepressants have been widely prescribed to treat patients with major depressive disease (MDD), there is little disagreement over the need for improved antidepressant therapeutics as the typical treatments have a slow therapeutic onset and moderate efficacy. In the present study, we assessed a novel compound, YY-21, from timosaponin B-III derived from sarsasapogenin of Anemarrhenae Rhizoma. From the initial results, we found that YY-21 obviously increased presynaptic glutamate release and enhanced long-term synaptic activity within 10min as determined by excitatory postsynaptic current (EPSC) and field excitatory postsynaptic potential (fEPSP) in medial prefrontal cortex (mPFC) slices, respectively. YY-21 demonstrated anxiolytic-like effects following acute administration in naïve animals and reversed the depressive-like and anxiety phenotypes induced by chronic unpredictable mild stress (CMS) with a relatively fast therapeutic onset. Furthermore, analysis of intracellular signaling pathways showed that YY-21 normalized the CMS-induced low protein levels of GluN2B, p-mTOR, synaptic-related proteins, such as BDNF, PSD-95 and GluA1. Pre-application of the mTOR-selective inhibitor rapamycin blocked YY-21-induced long-term synaptic enhancement. These findings suggest that the activation of BDNF-dependent mTOR signaling, which produces a rapid increase in the postsynaptic protein PSD-95 and GluA1 and further triggers the long-term enhancement of synaptic neurotransmission, may be the mechanism underlying the rapid antidepressant and anxiolytic effects induced by YY-21.

    The emergence and spread of multidrug-resistant P. aeruginosa infections is of great concern, as very few agents are effective against strains of this species. Methanolic extracts from the Coptidis Rhizoma (the rhizomes of Coptis japonica var. major Satake) or Phellodendri Cortex (the bark of Phellodendron chinense Schneider) markedly reduced resistance to anti-pseudomonal aminoglycosides (e.g., amikacin) in multidrug-resistant P. aeruginosa strains. Berberine, the most abundant benzylisoquinoline alkaloid in the two extracts, reduced aminoglycoside resistance of P. aeruginosa via a mechanism that required the MexXY multidrug efflux system; berberine also reduced aminoglycoside MICs in Achromobacter xylosoxidans and Burkholderia cepacia, two species that harbor intrinsic multidrug efflux systems very similar to the MexXY. Furthermore this compound inhibited MexXY-dependent antibiotic resistance of other classes including cephalosporins (cefepime), macrolides (erythromycin), and lincosamides (lincomycin) demonstrated using a pseudomonad lacking the four other major Mex pumps. Although phenylalanine-arginine beta-naphthylamide (PAβN), a well-known efflux inhibitor, antagonized aminoglycoside in a MexXY-dependent manner, a lower concentration of berberine was sufficient to reduce amikacin resistance of P. aeruginosa in the presence of PAβN. Moreover, berberine enhanced the synergistic effects of amikacin and piperacillin (and vice versa) in multidrug-resistant P. aeruginosa strains. Thus, berberine appears to be a novel type inhibitor of the MexXY-dependent aminoglycoside efflux in P. aeruginosa. As aminoglycosides are molecules of choice to treat severe infections the clinical impact is potentially important. PMID:27547203

    Xian-Ling-Gu-Bao capsule (XLGB), a well-known traditional Chinese medicine prescription (TCMP), is widely used for the treatment of osteoporosis. However, due to lack of metabolism research, the effective material of XLGB is still unknown. It entails a huge obstacle for the clinical-safe medication administration and quality control of XLGB. To explore the metabolic fate of multiple components of XLGB, herein, we proposed a "representative structure based homologous xenobiotics identification" (RSBHXI) strategy based on ultra performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC/Q-TOF-MS) and mass defect filter (MDF) technique. A total of 147 XLGB-related xenobiotics were identified or tentatively characterized in rat biofluids after oral administration of XLGB, including 134 (57 prototype components and 77 metabolites) in plasma, 93 (37 prototype components and 56 metabolites) in urine and 118 (46 prototype components and 72 metabolites) in bile. Our results indicated that prenylated flavonol glycosides from Herba epimedii, prenylated flavonoids from Fructus psoraleae, saponins from Radix dipsaci and Rhizoma anemarrahenae, as well as tanshinones from Radix Salviae Miltiorrhizae were major absorbed chemical components of XLGB. Hydrolysis, glucuronidation and sulfation were major metabolic reactions of XLGB. As more xenobiotics were detected in bile than those in urine, it demonstrated that multiple components of XLGB underwent comprehensive hepatobiliary excretion. The present study expands our knowledge about the metabolism of XLGB which will be conducive to revealing its in vivo pharmacological material basis. In addition, the application of RSBHXI strategy provides a new approach for metabolite identification of TCMPs and other complex mixture.

    Yupingfeng (YPF) is a kind of Astragali radix-based ancient Chinese herbal supplemented with Atractylodis Macrocephalae Rhizoma and Radix Saposhnikoviae. Increasing evidence has proven the beneficial immunomodulating activity of YPF. However, the action mechanism(s) of it is not known. Here, we explored the immunomodulatory activity of unfermented Yupingfeng polysaccharides (UYP) and fermented Yupingfeng polysaccharides (FYP) obtained using Rhizopus oligosporus SH in weaning Rex rabbits. The results showed that both UYP and FYP exhibited notable growth-promoting and immune-enhancing activities, improvement of the intestinal flora homeostasis, and maintenance of intestinal barrier integrity and functionality. Notably, compared with UYP, FYP effectively enhanced average daily gain, organ indices, interleukin-2 (IL-2), IL-4, IL-10, tumor necrosis factor-alpha (TNF-α), TLR2, and TLR4 mRNA levels in spleen, IL-1, IL-2, IL-4, IL-6, IL-10, IL-12, TNF-α, and IFN-γ protein concentrations in serum, and TLR2 and TLR4 mRNA expressions in the gastrointestinal tract (GIT). Moreover, FYP exhibited greater beneficial effects in improving the intestinal flora, including augment flora diversity and the abundance of cellulolytic bacteria, reduction the abundance of Streptococcus spp. and Enterococcus spp. in the GIT, particularly the foregut and maintaining the intestinal barrier integrity and functionality by upregulating zonula occludens 1, claudin, polymeric immunoglobulin receptor, trefoil factor, and epidermal growth factor mRNA levels in the jejunum and ileum. Our results indicated the immunoenhancement effect of FYP is superior over that of UYP, which is probably related with the amelioration of the intestinal microflora and intestinal barrier in the foregut.

    Extracorporeal shock wave lithotripsy (ESWL)-induced renal damage can occur as a result of multiple mechanisms. We have reported previously that Astragalus membranaceus, Salvia miltiorrhiza, a decoction of six drugs containing rhizoma Rehmanniae preparata and supplements of a few traditional Chinese medicinal herbs for invigorating the kidney and excreting calculus, have a protective effect on renal injury induced by high-energy shock waves (HESW) in rabbits. In this clinical study we further investigate the protective effects of these traditional Chinese herbs against renal damage induced by ESWL. Sixty consenting patients with renal calculus who underwent ESWL treatment were included and randomly assigned to the medication group or control group. Post-ESWL plasma nitric oxide (NO), endothelin-1 (ET-1), malondialdehyde (MDA), and serum tumor necrosis factor α (TNF-α) increased significantly in the controls (P < 0.05), while in the medication group, slightly but not significantly elevated levels of plasma ET-1, NO, and serum TNF-α were found. The difference between the groups was statistically significant (P < 0.05). The levels of superoxide dismutase (SOD) decreased gradually in the controls, reaching a trough 72 h after ESWL (P < 0.05), while in the treated group it was unchanged, and remained at a level higher versus the controls (P < 0.05). Plasma NO peaked twice by 72 h and at 1 week in the controls (P < 0.05). Urinary enzymes and β(2)-microglobulin increased significantly and peaked by 24 h and immediately after ESWL (P < 0.05). These values were greater in the controls, and the difference was statistically significant (P < 0.05). This study demonstrates that the preparations of traditional Chinese medicines for invigorating the kidney and excreting calculus can reduce renal tubular damage induced by ESWL, and can shorten the recovery time of renal tubules in human subjects.

    Paraquat poisoning causes multiple organ injury and high mortality due to severe toxicity and lack of effective treatment. Xuebijing (XBJ) injection, a traditional Chinese medicine preparation of five Chinese herbs (Radix Salviae Miltiorrhiae, Rhizoma Chuanxiong, Flos Carthami, Angelica Sinensis and Radix Paeoniae Rubra), has an anti-inflammatory effect and is widely used in the treatment of sepsis. This retrospective study was designed to evaluate the effects of XBJ combined with conventional therapy on mortality risk of patients with acute paraquat poisoning. Out of 68 patients, 27 were treated with conventional therapy (control group) and 41 were treated with intravenous administration of XBJ (100 ml, twice a day, up to 7 days) plus conventional therapy (XBJ group). Vital organ function, survival time within 28 days and adverse events during the treatment were reviewed. Results indicated that XBJ treatment significantly increased median survival time among patients ingesting 10-30 ml of paraquat (P=0.02) compared with the control group. After adjustment for covariates, XBJ treatment was associated significantly with a lower mortality risk (adjusted HR 0.242, 95% CI 0.113 to 0.516, P=0.001) compared with the control group. Additionally, compared with Day 1, on Day 3 the value of PaO2/FiO2 was significantly decreased, and the values of serum alanine aminotransferase, creatinine and troponin T were significantly increased in the control group (all P<0.05), but these values were significant improved in the XBJ group (all P<0.05). Only one patient had skin rash with itch within 30 minutes after injection and no severe adverse events were found in the XBJ group. In conclusion, XBJ treatment is associated with decreased mortality risk of patients with moderate paraquat poisoning, which may be attributed to improved function of vital organs with no severe adverse events.

    Wei Yuheng held that the endogenous miscellaneous diseases are mostly caused by liver diseases, highly stressed the treating method of nourishing yin to generate liver. He claimed that liver deficiency is mostly caused by congenital factors, sexual strain or improper treatment. He criticized that the improper treatment by elder generations mainly was caused by their ignorance of tonifying the liver based on the saying of "no tonifying treatment for the liver". Wei Yuheng's medical theories and clinical experiences are scattered in his book Xu Mingyi Lei'an (Supplement to Classified Case Records of Celebrated Physicians). Wang Mengying collected part of his thoughts and experiences and wrote the book Liuzhou Yihua (Liuzhou Medical Talks). Although Wang Mengying's book could deduce part of the thoughts of Wei Yuheng, it didn't disclose his theories completely. It is known to all that the compound recipe Yiguan Jian is a representative formula of Wei Yuheng to tonify liver yin. Actually, it can be concluded from the analysis of Xu Mingyi Lei'an that he used Fructus Lycii (Gouqi) as a main herb to tonify liver yin in the method of nourishing yin to generate liver. Based on the idea that there are accept, restriction, generation and transformation relationship among the lung, kidney and liver yin, so he also always used Radix Glehniae (Beishashen), Radix Ophiopogonis (Maidong), Radix Rehmanniae Recens (Shengdihuang), and Radix Rehmanniae Preparata (Shudihuang) in his compound recipes. If the yin blood is insufficient, Semen Ziziphi Spinosae (Suanzaoren) should be added. In order to prepare a out way for phlegm-heat caused dy liver yin deficiency, a lubricative, Semen Trichosanthis (Gualouren) was always used and raw Semen Coicis Recens (Shengyiyiren) too. Sichuan Rhizoma Coptidis (Chuanhuanglian) can be used to clear fire-heat, and Fructus Meliae Toosendan (Chuanlianzi) for pain caused by fire-heat. PMID:17096983

    Background Compound Valeriana jatamansi Jones is a formula for treating anxiety-related diseases in the clinic, which is composed of Valeriana jatamansi Rhizoma et Radix, Ziziphi Spinosae Semen, Albiziae Cortex and Junci Medulla. The purpose of this study was to explore the anxiolytic properties of this compound in mice. Methods Male ICR mice were treated with compound Valerianae Jatamansi Jones (1.2 g/kg, 2.4 g/kg, 4.8 g/kg), saline, diazepam (2 mg/kg) orally for 10 days and then exposed to elevated maze-plus (EPM) and light–dark box (LDB). The effects of the compound on spontaneous activity were evaluated by locomotor activity test. We further investigated the mechanism of action underlying the anxiolytic-like effect of compound by pre-treating animals with antagonists of benzodiazepine (flumazenil, 3mg/kg) prior to evaluation using EPM and LDB. Results Compound Valerianae Jatamansi Jones (2.4, 4.8 g/kg, p.o.) significantly increased entries (P<0.05) into and time spent (P<0.05) on the open arms of the EPM, and number of transitions (P<0.05) and time spent (P<0.05) in the light compartment of the LDB. However, the anxiolytic-like effects of compound were significantly reduced by pre-treatment with flumazenil (P>0.05). In addition, compound Valerianae Jatamansi Jones treatment didn’t affect the spontaneous activity in mice (P> 0.05). Conclusions The present study supports the hypothesis that compound Valeriana jatamansi Jones exert anxiolytic action but no sedative effects in mice and that this effect might be mediated by benzodiazepine receptors.

    Traditional Chinese medicine (TCM) has definitely clinical effect in treating hyperlipidemia, but the action mechanism still need to be explored. Based on consulting Chinese Pharmacopoeia (2010), all the lipid-lowering Chinese patent medicines were analyzed by associated rules data mining method to explore high frequency herb pairs. The top three couplet medicines with high support degree were Puerariae Lobatae Radix-Crataegi Fructus, Salviae Miltiorrhizae Radix et Rhizoma-Crataegi Fructus, and Polygoni Multiflori Radix-Crataegi Fructus. The 20 main ingredients were selected from the herb pairs and docked with 3 key hyperlipidemia targets, namely 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), peroxisome proliferator activated receptor-α (PPAR-α ) and niemann-pick C1 like 1 (NPC1L1) to further discuss the molecular mechanism of the high frequency herb pairs, by using the docking program, LibDock. To construct evaluation rules for the ingredients of herb pairs, the root-mean-square deviation (RMSD) value between computed and initial complexes was first calculated to validate the fitness of LibDock models. Then, the key residues were also confirmed by analyzing the interactions of those 3 proteins and corresponding marketed drugs. The docking results showed that hyperin, puerarin, salvianolic acid A and polydatin can interact with two targets, and the other five compounds may be potent for at least one of the three targets. In this study, the multi-target effect of high frequency herb pairs for lipid-lowering was discussed on the molecular level, which can help further researching new multi-target anti-hyperlipidemia drug.

    β-elemene, a compound derived from Rhizoma zedoariae, is a promising new plant-derived drug with broad-spectrum anticancer activity. However, the underlying mechanism by which this agent inhibits human lung cancer cell growth has not been well elucidated. In this study, we showed that β-elemene inhibits human non-small cell lung carcinoma (NSCLC) cell growth, and increased phosphorylation of ERK1/2, Akt and AMPKα. Moreover, β-elemene inhibited expression of DNA methyltransferase 1 (DNMT1), which was not observed in the presence of the specific inhibitors of ERK (PD98059) or AMPK (compound C). Overexpression of DNMT1 reversed the effect of β-elemene on cell growth. Interestingly, metformin not only reversed the effect of β-elemene on phosphorylation of Akt but also strengthened the β-elemene-reduced DNMT1. In addition, β-elemene suppressed Sp1 protein expression, which was eliminated by either ERK1/2 or AMPK inhibitor. Conversely, overexpression of Sp1 antagonized the effect of β-elemene on DNMT1 protein expression and cell growth. Taken together, our results show that β-elemene inhibits NSCLC cell growth viaERK1/2- and AMPKα-mediated inhibition of transcription factor Sp1, followed by reduction in DNMT1 protein expression. Metformin augments the effect of β-elemene by blockade of Akt signalling and additively inhibition of DNMT1 protein expression. The reciprocal ERK1/2 and AMPKα signalling pathways contribute to the overall responses of β-elemene. This study reveals a potential novel mechanism by which β-elemene inhibits growth of NSCLC cells.

    Berberine is one of active alkaloids from Rhizoma coptidis in traditional Chinese medicine. The pharmacokinetics of berberine in rat plasma were compared between normal and chronic visceral hypersensitivity irritable bowel syndrome rats (CVH-IBS) established by mechanical colon irritation using angioplasty balloons for 2 weeks after oral administration of berberine hydrochloride (25 mg/kg) with the equivalent dose of 22 mg/kg for berberine according to body weight. Immunohistochemical analysis of c-fos and myosin light chain kinase (MLCK) and immunofluorescence analysis of MLCK in rat colon were conducted. Quantification of berberine in rat plasma was achieved by using a sensitive and rapid UPLC-MS/MS method. Plasma samples were collected at 15 different points in time and the pharmacokinetic parameters were analyzed by WinNonlin software. The great different pharmacokinetic behavior of berberine was observed between normal and CVH-IBS model rats. Compared with normal group, T1/2 and AUC(0-t) of berberine in the model group were significantly increased, respectively (573.21 ± 127.53 vs 948.22 ± 388.57 min; 8,657.19 ± 1,562.54 vs 11,415.12 ± 1,670.72 min.ng/ml). Cl/F of berberine in the model group significantly decreased, respectively (13.89 ± 1.69 vs 9.19 ± 2.91 L/h/kg). Additionally, the expressions of c-fos and MLCK in model group were higher than those in normal group. The pharmacokinetic behavior of berberine was significantly altered in CVH-IBS pathological conditions, which indicated the dosage modification of berberine hydrochloride in CVH-IBS were necessary. Especially, improved exposure to berberine in rat plasma in CVH-IBS model rats was attributed to increased the expression of MLCK.

    Aim: Methyl eugenol is a major active component extracted from the Chinese herb Asari Radix et Rhizoma, which has been used to treat toothache and other pain. Previous in vivo studies have shown that methyl eugenol has anesthetic and antinociceptive effects. The aim of this study was to determine the possible mechanism underlying its effect on nervous system disorders. Methods: The direct interaction of methyl eugenol with Na+ channels was explored and characterized using electrophysiological recordings from Nav1.7-transfected CHO cells. Results: In whole-cell patch clamp mode, methyl eugenol tonically inhibited peripheral nerve Nav1.7 currents in a concentration- and voltage-dependent manner, with an IC50 of 295 μmol/L at a −100 mV holding potential. Functionally, methyl eugenol preferentially bound to Nav1.7 channels in the inactivated and/or open state, with weaker binding to channels in the resting state. Thus, in the presence of methyl eugenol, Nav1.7 channels exhibited reduced availability for activation in a steady-state inactivation protocol, strong use-dependent inhibition, enhanced binding kinetics, and slow recovery from inactivation compared to untreated channels. An estimation of the affinity of methyl eugenol for the resting and inactivated states of the channel also demonstrated that methyl eugenol preferentially binds to inactivated channels, with a 6.4 times greater affinity compared to channels in the resting state. The failure of inactivated channels to completely recover to control levels at higher concentrations of methyl eugenol implies that the drug may drive more drug-bound, fast-inactivated channels into drug-bound, slow-inactivated channels. Conclusion: Methyl eugenol is a potential candidate as an effective local anesthetic and analgesic. The antinociceptive and anesthetic effects of methyl eugenol result from the inhibitory action of methyl eugenol on peripheral Na+ channels. PMID:26051112

    Qing'E formula (QEF) is a clinically used prescription with four ingredients, Eucommiae Cortex, Psoraleae Fructus, Juglandis Semen and Garlic Rhizoma, from the Song dynasty (10th century CE). The present study aimed to investigate the anti-aging effect and mechanisms of QEF on D-galactose-induced aging mice. A mouse subacute aging model was established by subcutaneous injection of D-galactose at the neck consecutively for 8 weeks. Motor activity and memory impairment of the mice were evaluated by the rotarod test and passive avoidance test, respectively. Serum and liver parameters were analyzed with biochemical kits. Hippocampal mRNA and protein expression levels were examined by reverse transcription-quantitative polymerase chain reaction and western blotting, respectively. QEF administration significantly ameliorated the impaired motor and memory of aging mice. In the serum, QEF reduced blood urea nitrogen, creatinine, nitric oxide (NO) and malondialdehyde (MDA) levels, and inhibited alanine aminotransferase and aspartate aminotransferase activities. In the liver, QEF increased the glutathione level, enhanced total antioxidant capacity and catalase activity, deceased NO and MDA production, and reduced NO synthase activity. In the hippocampus, QEF elevated gene expression levels of Klotho, sirtuin 1 (SIRT1), forkhead box transcription factor O3, peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), insulin-like growth factor-1 and peroxiredoxin-3. QEF increased protein expression levels of Klotho and SIRT1, and decreased that of PGC-1α in the hippocampus. In conclusion, QEF attenuated the aging process in D-galactose-treated mice, which may be mediated through enhancing the antioxidants in the body, protecting renal and hepatic health, and balancing hippocampal expression levels of the longevity-related genes.

    The occurrence of multi-drug resistant highly pathogenic avian influenza virus (HPAIV) strains highlights the urgent need for strategies for the prevention and control of avian influenza virus. The aim of our current study is to evaluate the antiviral activity of dryocrassin ABBA isolated from Rhizoma Dryopteridis Crassirhizomatis (RDC) against an amantadine-resistant H5N1 (A/Chicken/Hebei/706/2005) strain in a mouse model. Post inoculation with HPAIV H5N1 virus in mice, the survival rate was 87, 80, and 60% respectively in the 33, 18, and 12.5 mg/kg dryocrassin ABBA-treated groups. On the other hand, the survival rate was 53 and 20%, respectively in the amantadine-treated group and untreated group. Mice administered with dryocrassin ABBA or amantadine showed a significant weight increase compared to the untreated group. Moreover, 33 and 18 mg/kg dryocrassin ABBA have decreased lung index (P >0.05) and virus loads (P <0.01) compared to the untreated group on day 7. Also, on day 7 bronchoalveolar lavage fluid pro-inflammatory cytokines (IL-6, TNF-α, and IFN-γ) decreased significantly (P <0.01) while anti-inflammatory cytokines (IL-10 and MCP-1) were increased significantly (P <0.01) in the 33 and 18 mg/kg dryocrassin ABBA-treated groups compared to the amantadine group and the untreated group. Moreover, the concentrations of IL-12 in drug-treated groups were significantly (P < 0.01) lowered compared with the untreated group. Based on the above we conclude that orally administered dryocrassin ABBA provided mice protection against avian influenza virus H5N1 by inhibiting inflammation and reducing virus loads. Dryocrassin ABBA is a potential novel lead compound which had antiviral effects on amantadine-resistant avian influenza virus H5N1 infection.

    Si-Wu-Tang (SWT), a traditional Chinese formula, has been clinically used in the treatment of cutaneous pruritus, chronic inflammation, and other diseases. The present study was carried out to observe the antipruritic and antiinflammatory effects of SWT aqueous extract using compound 48/80 and picryl chloride (PC) models in mice. SWT (500, 1000 mg/kg p.o.) clearly reduced the scratching responses elicited by compound 48/80 in normal mice. At doses of 250 and 500 mg/kg, it inhibited the scratching responses induced by PC in mice actively sensitized with 2,4-dinitrophenol (DNP)-ovalbumin (OVA) plus alum. Furthermore, SWT (250, 500, 1000 mg/kg) significantly inhibited the footpad swelling caused by compound 48/80 in mice. In the biphasic ear skin reactions induced by PC in actively sensitized mice, SWT (250, 500 mg/kg) reduced the immediate-phase reaction, but did not affect the late-phase reaction. In vitro, SWT (50-500 microg/ml) showed a concentration-dependent inhibition of the histamine release induced by compound 48/80 from rat peritoneal mast cells. The crude drugs contained in SWT, Paeoniae Radix (25, 100 microg/ml), Rehmanniae Radix, and Chuanxiong Rhizoma (100 microg/ml), also showed a clear inhibition, but Angelica Radix did not at the concentrations examined. These findings indicate that SWT aqueous extract has antipruritic and antiinflammatory effects in mice. SWT inhibits histamine release from rat mast cells, and Paeoniae Radix probably plays a crucial role in the formula.

    The aim of the study is to evaluate the efficacy of Chinese herbs (Angelica sinensis, Ligusticum wallichii, Salvia miltiorrhiza, Rhizoma dioscoreae, Rhodiola crenilata, Astragalus membranaceus and Angelica sinensis) on adenine-induced chronic renal failure in rats. 30 age-matched male Wistar rats were divided into three groups. Rats in group A (n = 10), B (n = 10) and C (n = 10) were fed a standard laboratory chow and allowed tap water ad libitum. In group B and C, renal failure was induced by the administration of a diet containing 0.75% adenine for 28 days which began at day 0. Rats in group C were given Chinese herbs (40 ml/kg with drug concentration 1.75 g/ml) beginning at day 0. Urine albumin, blood urea nitrogen (BUN) and creatinine were determined at days 0, 14 and 28. At day 28, the animals were killed and their kidneys removed for light microscope evaluation. Body weight in Group B decreased more significantly than that in Group C (p = 0.032) at day 28. The rats in group B demonstrated more severe proteinuria and higher Serum creatinine and BUN levels than group C at day 14 and day 28 (P < 0.05, 0.01). All rats given adenine developed marked structural renal damage involving the tubule and interstitium. The values were much less severe in group C than those in group B. In adenine-induced chronic renal failure rats, the protective effects of these Chinese herbs were of a significant nature. Our results do support the notion that these Chinese herbs are useful in deferring the advance of chronic renal failure. We recommend Chinese herbs as a beneficial treatment for pre-end stage chronic renal failure.

    Retained placenta remains therapeutic challenge in cattle. Certain traditional medicines are believed to be able to alleviate retained placenta condition and improve overall fertility in cows. The aim of the present study was to evaluate the efficacy of an herbal tincture for treatment of retained placenta. The herbal tincture was extracted from a combination of Herba Leonuri, Angelicae Sinensis Radix, Flos Carthami, Myrrha and Rhizoma Cyperi by percolation with 70% ethanol to a concentration of 0.5g crude herb/ml. Cows diagnosed with retained placenta (n=48) were randomly divided into one of two treatment groups (A and B), with animals in group A (n=26) receiving herbal tincture orally, and cows in group B (n=22) receiving oxytetracycline infusion into the uterus. Eighty six cows with no clinically visible pathological conditions, given birth alone and with no retained placenta diagnosis were included into control group (C). Retained placenta was expelled within 72h following initial treatment in 19 cows in group A, yet no cows in group B were recorded to expel placenta in the same time. The median number of days to first service (70.0 vs. 102.5 days; P<0.05) and median number of days open (76.0 vs. 134.0 days; P<0.01) were lower in group A than in group B. Percentage of cows pregnant within 100 days postpartum was the highest for animals in group A compared to controls (61.5% vs. 39.5%, P<0.05), and for animals in group B (61.5% vs. 22.7%; P<0.01). Herbal tincture used in the present study might facilitate expulsion of retained placenta and improve subsequent fertility, thus could present effective treatment option for retained placenta in cows.

  7. Enhanced antitumor efficacy of cisplatin in combination with HemoHIM in tumor-bearing mice

    2009-01-01

    Background Although cisplatin is one of the most effective chemotherapeutic agents, cisplatin alone does not achieve a satisfactory therapeutic outcome. Also cisplatin accumulation shows toxicity to normal tissues. In this study, we examined the possibility of HemoHIM both to enhance anticancer effect with cisplatin and to reduce the side effects of cisplatin in melanoma-bearing mice. Methods HemoHIM was prepared by adding the ethanol-insoluble fraction to the total water extract of a mixture of 3 edible herbs, Angelica Radix, Cnidium Rhizoma and Paeonia Radix. Anticancer effects of HemoHIM with cisplatin were evaluated in melanoma-bearing mice. We used a Cr51-release assay to measure the activity of NK/Tc cell and ELISA to evaluate the production of cytokines. Results In melanoma-bearing mice, cisplatin (4 mg/kg B.W.) reduced the size and weight of the solid tumors, and HemoHIM supplementation with cisplatin enhanced the decrease of both the tumor size (p < 0.1) and weight (p < 0.1). HemoHIM itself did not inhibit melanoma cell growth in vitro, and did not disturb the effects of cisplatin in vitro. However HemoHIM administration enhanced both NK cell and Tc cell activity in mice. Interestingly, HemoHIM increased the proportion of NK cells in the spleen. In melanoma-bearing mice treated with cisplatin, HemoHIM administration also increased the activity of NK cells and Tc cells and the IL-2 and IFN-γ secretion from splenocytes, which seemed to contribute to the enhanced efficacy of cisplatin by HemoHIM. Also, HemoHIM reduced nephrotoxicity as seen by tubular cell of kidney destruction. Conclusion HemoHIM may be a beneficial supplement during cisplatin chemotherapy for enhancing the anti-tumor efficacy and reducing the toxicity of cisplatin. PMID:19292900

    Atractylodes lancea (Thunb.) DC., named “Cangzhu” in China, which belongs to the Asteraceae family. In some countries of Southeast Asia (China, Thailand, Korea, Japan etc.) its rhizome, commonly called rhizoma atractylodis, is used to treat many diseases as it contains a variety of sesquiterpenoids and other components of medicinal importance. Despite its medicinal value, the information of the sesquiterpenoid biosynthesis is largely unknown. In this study, we investigated the transcriptome analysis of different tissues of non-model plant A. lancea by using short read sequencing technology (Illumina). We found 62,352 high quality unigenes with an average sequence length of 913 bp in the transcripts of A. Lancea. Among these, 43,049 (69.04%), 30,264 (48.53%), 26,233 (42.07%), 17,881 (28.67%) and 29,057(46.60%) unigenes showed significant similarity (E-value<1e-5) to known proteins in Nr, KEGG, SWISS-PROT, GO, and COG databases, respectively. Of the total 62,352 unigenes, 43,049 (Nr Database) open reading frames were predicted. On the basis of different bioinformatics tools we identify all the enzymes that take part in the terpenoid biosynthesis as well as five different known sesquiterpenoids via cytosolic mevalonic acid (MVA) pathway and plastidal methylerythritol phosphate (MEP) pathways. In our study, 6, 864 Simple Sequence Repeats (SSRs) were also found as great potential markers in A. lancea. This transcriptomic resource of A. lancea provides a great contribution in advancement of research for this specific medicinal plant and more specifically for the gene mining of different classes of terpenoids and other chemical compounds that have medicinal as well as economic importance.

    Nonalcoholic fatty liver disease (NAFLD), the hepatic manifestation of the metabolic syndrome, has become one of the most common causes of chronic liver disease over the last decade in developed countries. NAFLD includes a spectrum of pathological hepatic changes, such as steatosis, steatohepatitis, advanced fibrosis, and cirrhosis. Bisdemethoxycurcumin (BDMC) is polyphenolic compounds with a diarylheptanoid skeleton, curcumin close analogues, which is derived from the Curcumae Longae Rhizoma. While the rich bioavailability research of curcumin, BDMC is the poor studies. We investigated whether BDMC has the hepatoprotective effect and combinatory preventive effect with silymarin on methionine choline deficient (MCD)-diet-induced NAFLD in C57BL/6J mice. C57BL/6J mice were divided into five groups of normal (normal diet without any treatment), MCD diet (MCD diet only), MCD + silymarin (SIL) 100 mg/kg group, MCD + BDMC 100 mg/kg group, MCD + SIL 50 mg/kg + BDMC 50 mg/kg group. Body weight, liver weight, liver function tests, histological changes were assessed and quantitative real-time polymerase chain reaction and Western blot analyses were conducted after 4 weeks. Mice lost body weight on the MCD-diet, but BDMC did not lose less than the MCD-diet group. Liver weights decreased from BDMC, but they increased significantly in the MCD-diet groups. All liver function test values decreased from the MCD-diet, whereas those from the BDMC increased significantly. The MCD- diet induced severe hepatic fatty accumulation, but the fatty change was reduced in the BDMC. The BDMC showed an inhibitory effect on liver lipogenesis by reducing associated gene expression caused by the MCD-diet. In all experiments, the combinations of BDMC with SIL had a synergistic effect against MCD-diet models. In conclusion, our findings indicate that BDMC has a potential suppressive effect on NAFLD. Therefore, our data suggest that BDMC may act as a novel and potent therapeutic agent against NAFLD

    Quality by design (QbD) concept is a paradigm for the improvement of botanical injection quality control. In this work, water precipitation process for the manufacturing of Xueshuantong injection, a botanical injection made from Notoginseng Radix et Rhizoma, was optimized using a design space approach as a sample. Saponin recovery and total saponin purity (TSP) in supernatant were identified as the critical quality attributes (CQAs) of water precipitation using a risk assessment for all the processes of Xueshuantong injection. An Ishikawa diagram and experiments of fractional factorial design were applied to determine critical process parameters (CPPs). Dry matter content of concentrated extract (DMCC), amount of water added (AWA), and stirring speed (SS) were identified as CPPs. Box-Behnken designed experiments were carried out to develop models between CPPs and process CQAs. Determination coefficients were higher than 0.86 for all the models. High TSP in supernatant can be obtained when DMCC is low and SS is high. Saponin recoveries decreased as DMCC increased. Incomplete collection of supernatant was the main reason for the loss of saponins. Design space was calculated using a Monte-Carlo simulation method with acceptable probability of 0.90. Recommended normal operation region are located in DMCC of 0.38-0.41 g/g, AWA of 3.7-4.9 g/g, and SS of 280-350 rpm, with a probability more than 0.919 to attain CQA criteria. Verification experiment results showed that operating DMCC, SS, and AWA within design space can attain CQA criteria with high probability.

    The emergence and spread of multidrug-resistant P. aeruginosa infections is of great concern, as very few agents are effective against strains of this species. Methanolic extracts from the Coptidis Rhizoma (the rhizomes of Coptis japonica var. major Satake) or Phellodendri Cortex (the bark of Phellodendron chinense Schneider) markedly reduced resistance to anti-pseudomonal aminoglycosides (e.g., amikacin) in multidrug-resistant P. aeruginosa strains. Berberine, the most abundant benzylisoquinoline alkaloid in the two extracts, reduced aminoglycoside resistance of P. aeruginosa via a mechanism that required the MexXY multidrug efflux system; berberine also reduced aminoglycoside MICs in Achromobacter xylosoxidans and Burkholderia cepacia, two species that harbor intrinsic multidrug efflux systems very similar to the MexXY. Furthermore this compound inhibited MexXY-dependent antibiotic resistance of other classes including cephalosporins (cefepime), macrolides (erythromycin), and lincosamides (lincomycin) demonstrated using a pseudomonad lacking the four other major Mex pumps. Although phenylalanine-arginine beta-naphthylamide (PAβN), a well-known efflux inhibitor, antagonized aminoglycoside in a MexXY-dependent manner, a lower concentration of berberine was sufficient to reduce amikacin resistance of P. aeruginosa in the presence of PAβN. Moreover, berberine enhanced the synergistic effects of amikacin and piperacillin (and vice versa) in multidrug-resistant P. aeruginosa strains. Thus, berberine appears to be a novel type inhibitor of the MexXY-dependent aminoglycoside efflux in P. aeruginosa. As aminoglycosides are molecules of choice to treat severe infections the clinical impact is potentially important. PMID:27547203

    Aim: N-methyl-D-aspartic acid (NMDA) receptor modulators have shown promising results as potential antidepressant agents, whereas timosaponins extracted from the Chinese herb Rhizoma Anemarrhenae exhibit antidepressant activities. In the present study we examined whether YY-23, a modified metabolite of timosaponin B-III, could affect NMDA receptors in rat hippocampal neurons in vitro, and evaluated its antidepressant-like effects in stressed mice. Methods: NMDA-induced currents were recorded in acutely dissociated rat hippocampal CA1 neurons using a whole-cell recording technique. C57BL/6 mice were exposed to a 6-week chronic mild stress (CMS) or a 10-d chronic social defeat stress (CSDS). The stressed mice were treated with YY-23 (20 mg·kg−1·d−1) or a positive-control drug, fluoxetine (10 mg·kg−1·d−1) for 3 weeks. Behavioral assessments were carried out every week. Results: In acutely dissociated rat hippocampal CA1 neurons, YY-23 selectively and reversibly inhibited NMDA-induced currents with an EC50 value of 2.8 μmol/L. This inhibition of NMDA-induced currents by YY-23 was non-competitive, and had no features of voltage-dependency or use-dependency. Treatment of the stressed mice with YY-23 not only reversed CMS-induced deficiency of sucrose preference and immobility time, and CSDS-induced reduction of social interaction, but also had faster onset as compared to fluoxetine. Conclusion: YY-23 is a novel non-competitive antagonist of NMDA receptors with promising rapid antidepressant-like effects in mouse models of CMS and CSDS depression. PMID:26687936

    Forage-based livestock systems have been implicated as major contributors to deteriorating water quality, particularly for phosphorus (P) from commercial fertilizers and manures affecting surface and ground water quality. Little information exists regarding possible magnitudes of nutrient losses from pastures that are managed for both grazing and hay production and how these might impact adjacent bodies of water. We examined the changes that have occurred in soil fertility levels of rhizoma peanut (Arachis glabrata Benth.)-based beef cattle pastures (n = 4) in Florida from 1988 to 2002. These pastures were managed for grazing in spring followed by haying in late summer and were fertilized annually with P (39 kg P2O5 ha(-1)) and K (68 kg K2O ha(-1)). Additionally, we investigated trends in water quality parameters and trophic state index (TSI) of lakes (n = 3) associated with beef cattle operations from 1993 to 2002. Overall, there was no spatial or temporal buildup of soil P and other crop nutrients despite the annual application of fertilizers and daily in-field loading of animal waste. In fact, soil fertility levels showed a declining trend for crop nutrient levels, especially soil P (y = 146.57 - 8.14 x year; r2= 0.75), even though the fields had a history of P fertilization and the cattle were rotated into the legume fields. Our results indicate that when nutrients are not applied in excess, cow-calf systems are slight exporters of P, K, Ca, and Mg through removal of cut hay. Water quality in lakes associated with cattle production was "good" (30-46 TSI) based on the Florida Water Quality Standard. These findings indicate that properly managed livestock operations may not be major contributors to excess loads of nutrients (especially P) in surface water. PMID:16397100

  14. Evaluation of the transporter-mediated herb-drug interaction potential of DA-9801, a standardized dioscorea extract for diabetic neuropathy, in human in vitro and rat in vivo

    Background Drug transporters play important roles in the absorption, distribution, and elimination of drugs and thereby, modulate drug efficacy and toxicity. With a growing use of poly pharmacy, concurrent administration of herbal extracts that modulate transporter activities with drugs can cause serious adverse reactions. Therefore, prediction and evaluation of drug-drug interaction potential is important in the clinic and in the drug development process. DA-9801, comprising a mixed extract of Dioscoreae rhizoma and Dioscorea nipponica Makino, is a new standardized extract currently being evaluated for diabetic peripheral neuropathy in a phase II clinical study. Method The inhibitory effects of DA-9801 on the transport functions of organic cation transporter (OCT)1, OCT2, organic anion transporter (OAT)1, OAT3, organic anion transporting polypeptide (OATP)1B1, OATP1B3, P-glycoprotein (P-gp), and breast cancer resistance protein (BCRP) were investigated in HEK293 or LLC-PK1 cells. The effects of DA-9801 on the pharmacokinetics of relevant substrate drugs of these transporters were also examined in vivo in rats. Results DA-9801 inhibited the in vitro transport activities of OCT1, OCT2, OAT3, and OATP1B1, with IC50 values of 106, 174, 48.1, and 273 μg/mL, respectively, while the other transporters were not inhibited by 300 μg/mL DA-9801. To investigate whether this inhibitory effect of DA-9801 on OCT1, OCT2, and OAT3 could change the pharmacokinetics of their substrates in vivo, we measured the pharmacokinetics of cimetidine, a substrate for OCT1, OCT2, and OAT3, and of furosemide, a substrate for OAT1 and OAT3, by co-administration of DA-9801 at a single oral dose of 1,000 mg/kg. Pre-dose of DA-9801 5 min or 2 h prior to cimetidine administration decreased the Cmax of cimetidine in rats. However, DA-9801 did not affect the elimination parameters such as half-life, clearance, or amount excreted in the urine, suggesting that it did not inhibit elimination

    With an increasing use of traditional Chinese medicine (TCM) in type 2 diabetes mellitus (T2DM), evidence of long-term benefit with adjunctive TCM treatment is limited. This study investigated whether the concurrent TCM treatment reduces the risk of vascular complications in T2DM patients by using a large population from National Health Insurance Research Database (NHIRD).We identified 33,457 adult patients with newly diagnosed T2DM using anti-diabetic agents from a random sample of one million beneficiaries in the NHIRD between January 1, 2000 and December 31, 2011. We recruited 1049 TCM users (received TCM over 30 days with a diagnosis of T2DM) and randomly selected 4092 controls as the non-TCM cohort at a ratio of 1:4 frequency-matched by age, sex, hypertension, hyperlipidemia, and index year. We investigated the prescription pattern of TCM and conducted a Cox proportional hazards regression to calculate the hazard ratios (HRs) of stroke, chronic kidney diseases (CKD), and diabetic foot between the 2 cohorts.In the TCM cohort, the prescription pattern of TCM was different between insulin and noninsulin patients. The most common herbs were Dan-Shen (Radix Salviae Miltiorrhizae) in noninsulin group and Da-Huang (Radix et Rhizoma Rhei) in insulin group. The most common formulae were Liu-Wei-Di-Huang-Wan in noninsulin group and Yu-Quan-Wan in insulin group. Although no significant reduction in the hazard ratio of CKD and diabetic foot, the incidence rate of stroke was 7.19 per 1000 person-years in the TCM cohort and 10.66 per 1000 person-years in the control cohort, respectively. After adjustment of age, sex, hypertension, hyperlipidemia, and antidiabetes agent use (including sulfonylureas, α-glucosidase, metformin, meglitinide, thiazolidinediones, and insulin), TCM cohorts were found to have a 33% decreased risk of stroke (95% CI = 0.46-0.97; P < 0.05).This population-based retrospective study showed that the complementary TCM therapy might associate with

    Coptidis rhizoma (Coptis) and its alkaloids exert various pharmacological functions in cells and tissues; however, the oral absorption of these alkaloids requires further elucidation. The present study aimed to examine the mechanism underlying the poor absorption of alkaloids, including berberine (BER), coptisine (COP), palmatine (PAL) and jatrorrhizine (JAT). An ultra‑performance liquid chromatography (UPLC) method was validated for the determination of BER, COP, PAL and JAT in the above experimental medium. In addition, the apparent oil‑water partition coefficient (Po/w); apparent permeability coefficient (Papp), determined using a parallel artificial membrane permeability assay (PAMPA) plate; membrane retention coefficient (R %); and effect of P‑glycoprotein (P‑gp) inhibitor on the Papp of the four alkaloids were investigated. The intestinal absorption rate constant (Ka) and absorption percentage (A %) of the four alkaloids were also determined. The results of the present study demonstrated that the Po/w of the four alkaloids in 0.1 mol·l‑1 HCl medium was significantly higher (P<0.01), compared with those of the alkaloids in phosphate buffer (pH 7.4). The Papp of BER was 1.0‑1.2x10‑6 cm·s‑1, determined using a PAMPA plate, and the Papp of BER, COP, PAL and JAT decreased sequentially. The concentrations of the four alkaloids on the apical‑to‑basolateral (AP‑BL) surface and the basolateral‑to‑apical (BL‑AP) surface increased in a linear manner, with increasing concentrations between 10 and 100 µmol. In addition, the transportation of BER on the BL‑AP surface was significantly faster (P<0.01), compared with that on the AP‑BL surface and, following the addition of verpamil (a P‑gp inhibitor), the Papp (AP‑BL) of the four alkaloids increased, whereas the Papp (BL‑AP) was significantly decreased (P<0.01). The rat intestinal perfusion experiment demonstrated that the four alkaloids were poorly absorbed; however, the Ka of BER

    3β-O-{α-L-Pyran rhamnose-(1→3)-[β-D-xylopyranose-(1→2)]-β-D-glucopyranose-(1→4)-[β-D-lucopyranose-(1→2)]-α-L-pyran arabinose}-cyclamiretin A (AG4) is a saponin component obtained from the Giantleaf Ardisia Rhizome (Rhizoma Ardisiae Gigantifoliae). The present study aimed to investigate the antitumor potential of AG4 and its possible mechanisms in human nasopharyngeal carcinoma cells (CNE). We exposed tumor cells to AG4 to investigate which cell line was the most sensitive to AG4. Cell viability was assessed using the MTT reduction assay, and the effects of AG4 on apoptosis, reactive oxygen species (ROS) content, mitochondrial membrane potential (MMP), and cell cycle were detected using a flow cytometer; the glutathione, superoxide dismutase and malondialdehyde activities were measured using colorimetric methods. The relative expressions of Bax, Bad, Bid, Bcl-2, and Fas mRNA were calculated using the (Equation is included in full-text article.)comparative method by real-time PCR studies and protein was detected by western blotting. AG4 markedly inhibited the growth of CNE cells by decreasing cell proliferation, inducing apoptosis, and blocking the cell cycle in the S phase. The release of caspase-3, caspase-8, and caspase-9 was stimulated by AG4 in CNE, and the decreased proliferation induced by AG4 was blocked by the inhibitor of pan caspase (Z-VAD-FMK). Moreover, the MMP was decreased in AG4-treated cells, and AG4-induced cell apoptosis was accompanied by a rapid and lasting increase in ROS, which was abolished by N-acetyl-L-cysteine (NAC); glutathione, superoxide dismutase, and malondialdehyde were regulated by AG4. AG4 inhibited Bcl-2 mRNA and protein expression and stimulated Bax, Bad, Bid, Fas mRNA, and protein expression in CNE cultures, suggesting an effect at the transcriptional and protein level. In addition, both the FasL inhibitor (AF-016) and the Bcl-2 family inhibitor (GX15-070) could prevent the cell apoptosis induced by AG4. The

    Huanglian-Jie-Du-Tang (HLJDT) is a famous traditional Chinese herbal formula that has been widely used clinically to treat cerebral ischemia. Recently, we found that berberine, a major alkaloid compound in HLJDT, reduced amyloid-β (Aβ) accumulation in an Alzheimer’s disease (AD) mouse model. In this study, we compared the effects of HLJDT, four single component herbs of HLJDT (Rhizoma coptidis (RC), Radix scutellariae (RS), Cortex phellodendri (CP) and Fructus gardenia (FG)) and the modified formula of HLJDT (HLJDT-M, which is free of RS) on the regulatory processing of amyloid-β precursor protein (APP) in an in vitro model of AD. Here we show that treatment with HLJDT-M and its components RC, CP, and the main compound berberine on N2a mouse neuroblastoma cells stably expressing human APP with the Swedish mutation (N2a-SwedAPP) significantly decreased the levels of full-length APP, phosphorylated APP at threonine 668, C-terminal fragments of APP, soluble APP (sAPP)-α and sAPPβ-Swedish and reduced the generation of Aβ peptide in the cell lysates of N2a-SwedAPP. HLJDT-M showed more significant APP- and Aβ- reducing effects than berberine, RC or CP treatment alone. In contrast, HLJDT, its component RS and the main active compound of RS, baicalein, strongly increased the levels of all the metabolic products of APP in the cell lysates. The extract from FG, however, did not influence APP modulation. Interestingly, regular treatment of TgCRND8 APP transgenic mice with baicalein exacerbated the amyloid plaque burden, APP metabolism and Aβ production. Taken together, these data provide convincing evidence that HLJDT and baicalein treatment can increase the amyloidogenic metabolism of APP which is at least partly responsible for the baicalein-mediated Aβ plaque increase in the brains of TgCRND8 mice. On the other hand, HLJDT-M significantly decreased all the APP metabolic products including Aβ. Further study of HLJDT-M for therapeutic use in treating AD is

    Abstract With an increasing use of traditional Chinese medicine (TCM) in type 2 diabetes mellitus (T2DM), evidence of long-term benefit with adjunctive TCM treatment is limited. This study investigated whether the concurrent TCM treatment reduces the risk of vascular complications in T2DM patients by using a large population from National Health Insurance Research Database (NHIRD). We identified 33,457 adult patients with newly diagnosed T2DM using anti-diabetic agents from a random sample of one million beneficiaries in the NHIRD between January 1, 2000 and December 31, 2011. We recruited 1049 TCM users (received TCM over 30 days with a diagnosis of T2DM) and randomly selected 4092 controls as the non-TCM cohort at a ratio of 1:4 frequency-matched by age, sex, hypertension, hyperlipidemia, and index year. We investigated the prescription pattern of TCM and conducted a Cox proportional hazards regression to calculate the hazard ratios (HRs) of stroke, chronic kidney diseases (CKD), and diabetic foot between the 2 cohorts. In the TCM cohort, the prescription pattern of TCM was different between insulin and noninsulin patients. The most common herbs were Dan-Shen (Radix Salviae Miltiorrhizae) in noninsulin group and Da-Huang (Radix et Rhizoma Rhei) in insulin group. The most common formulae were Liu-Wei-Di-Huang-Wan in noninsulin group and Yu-Quan-Wan in insulin group. Although no significant reduction in the hazard ratio of CKD and diabetic foot, the incidence rate of stroke was 7.19 per 1000 person-years in the TCM cohort and 10.66 per 1000 person-years in the control cohort, respectively. After adjustment of age, sex, hypertension, hyperlipidemia, and antidiabetes agent use (including sulfonylureas, α-glucosidase, metformin, meglitinide, thiazolidinediones, and insulin), TCM cohorts were found to have a 33% decreased risk of stroke (95% CI = 0.46–0.97; P < 0.05). This population-based retrospective study showed that the complementary TCM therapy might

    Rhizoma Chuanxiong (CX) and Radix Angelica sinensis (DG) are very important Traditional Chinese Medicine (TCM) and usually used in clinic. They both are from the Umbelliferae family, and have almost similar chemical constituents with each other. It is complicated, time-consuming and laborious to discriminate them by using the chromatographic methods such as high performance liquid chromatography (HPLC) and gas chromatography (GC). Therefore, to find a fast, applicable and effective identification method for two herbs is urged in quality research of TCM. In this paper, by using a three-stage infrared spectroscopy (Fourier transform infrared spectroscopy (FT-IR), the second derivative infrared spectroscopy (SD-IR) and two-dimensional correlation infrared spectroscopy (2D-IR)), we analyzed and discriminated CX, DG and their different extracts (aqueous extract, alcoholic extract and petroleum ether extract). In FT-IR, all the CX and DG samples' spectra seemed similar, but they had their own unique macroscopic fingerprints to identify. Through comparing with the spectra of sucrose and the similarity calculation, we found the content of sucrose in DG raw materials was higher than in CX raw materials. The significant differences in alcoholic extract appeared that in CX alcoholic extract, the peaks at 1743 cm-1 was obviously stronger than the peak at same position in DG alcoholic extract. Besides in petroleum ether extract, we concluded CX contained much more ligustilide than DG by the similarity calculation. With the function of SD-IR, some tiny differences were amplified and overlapped peaks were also unfolded in FT-IR. In the range of 1100-1175 cm-1, there were six peaks in the SD-IR spectra of DG and the intensity, shape and location of those six peaks were similar to that of sucrose, while only two peaks could be observed in that of CX and those two peaks were totally different from sucrose in shape and relative intensity. This result was consistent with that of the
