    A green one step facile synthesis of graphene nanosheets by Terminalia chebula (T. chebula) extract mediated reduction of graphite oxide (GO) is reported in this work. This method avoids the use of harmful toxic reducing agents. The comparative results of various characterizations of GO and T. chebula reduced graphene oxide (TCG) provide a strong indication of the exclusion of oxygen containing groups from graphene oxide and successive stabilization of the formed reduced graphene oxide (RGO). The functionalization of reduced graphene oxide with the oxidized polyphenols causes their stability by preventing the aggregation. We also have proposed how the oxidized polyphenols are accountable for the stabilization of the formed graphene sheets. PMID:25770934

    Medicinal plants are part and parcel of human society to combat diseases from the dawn of civilization. Terminalia chebula Retz. (Fam. Combretaceae), is called the ‘King of Medicine’ in Tibet and is always listed at the top of the list of ‘Ayurvedic Materia Medica’ because of its extraordinary power of healing. The whole plant possesses high medicinal value and traditionally used for the treatment of various ailments for human beings. Some of the folklore people used this plant in the treatment of asthma, sore throat, vomiting, hiccough, diarrhea, dysentery, bleeding piles, ulcers, gout, heart and bladder diseases. The plant has been demonstrated to possess multiple pharmacological and medicinal activities, such as antioxidant, antimicrobial, antidiabetic, hepatoprotective, anti-inflammatory, antimutagenic, antiproliferative, radioprotective, cardioprotective, antiarthritic, anticaries, gastrointestinal motility and wound healing activity. But no systematic updated information on the therapeutic effectiveness of Terminalia chebula, a popular herbal remedy in India and South-East Asia has so far been reported. This review highlights an updated information particularly on the phytochemistry and various pharmacological and medicinal properties of Terminalia chebula Retz. and some of its isolated compounds, along with their safety evaluation. This may provide incentive for proper evaluation of the plant as medicinal agent against the human diseases and also to bridge the lacunae in the existing literature and future scope which may offer immense opportunity for researchers engaged in validation of the traditional claims and development of safe and effective botanical medicine.

    Antitussive effects of ethyl acetate fraction of Terminalia chebula on sulphur dioxide (SO2) gas induced cough have been examined in mice. Safety profile of Terminalia chebula was established by determining LD50 and acute neurotoxicity. The result showed that extract of Terminalia chebula dose dependently suppressed SO2 gas induced cough in mice. Terminalia chebula, after i.p. administration at dose level 500 mg/kg, offered maximum cough suppressive effects; that is, number of coughs at 60 min was 12 ± 1.52 (mean ± SEM) as compared to codeine 10 mg/kg; i.p., dextromethorphan 10 mg/kg; i.p., and saline, having frequency of cough 10.375 ± 0.866, 12.428 ± 0.81, and 46 ± 2.61, respectively. LD50 value of Terminalia chebula was approximately 1265 mg/kg, respectively. No sign of neural impairment was observed at antitussive doses of extract. Antitussive effect of Terminalia chebula was partly reversed with treatment by naloxone (3 mg/kg; s.c.) while rimcazole (3 mg/kg; s.c.) did not antagonize its cough suppression activity. This may suggest that opioid receptors partially contribute in antitussive action of Terminalia chebula. Along with this, the possibility of presence of single or multiple mechanisms activated by several different pharmacological actions (mainly anti-inflammatory, antioxidant, spasmolytic, antibacterial, and antiphlegmatic) could not be eliminated.

    Biologically inspired experimental process in synthesising nanoparticles is of great interest in present scenario. Biosynthesis of nanoparticles is considered to be one of the best green techniques in synthesising metal nanoparticles. Here, an in situ green biogenic synthesis of gold nanoparticles using aqueous extracts of Terminalia chebula as reducing and stabilizing agent is reported. Gold nanoparticles were confirmed by surface plasmon resonance in the range of 535 nm using UV-visible spectrometry. TEM analysis revealed that the morphology of the particles thus formed contains anisotropic gold nanoparticles with size ranging from 6 to 60 nm. Hydrolysable tannins present in the extract of T. chebula are responsible for reductions and stabilization of gold nanoparticles. Antimicrobial activity of gold nanoparticles showed better activity towards gram positive S. aureus compared to gram negative E. coli using standard well diffusion method.

    This study investigates the effects of Terminalia chebula Retz. meal supplementation on rumen fermentation and methane (CH4 ) production by using an in vitro gas technique. The experimental design was a completely randomized design (CRD) and the dietary treatments were T. chebula supplementation at 0, 4, 8, 12, 16 and 20 mg with 0.5 g of roughage and concentrate ratio at 60:40. The results revealed that cumulative gas production (96 h of incubation) were higher (P < 0.01) with T. chebula supplementation at 12, 16 and 20 mg than other treatments. However, in vitro dry matter degradability (IVDMD) and in vitro organic matter digestibility (IVOMD) were not significantly different among treatments (P > 0.05). The NH3 -N concentrations tended to quadratically increase with increasing levels of T. chebula in the diet. In addition, total volatile fatty acids (VFA) and propionate concentrations were increased (P < 0.01), while acetate concentration, acetate-to-propionate ratio, CH4 production and protozoal populations were decreased (P < 0.01) when supplemented with T. chebula at 8, 12 and 16 mg, respectively. Based on this study, it could be concluded that supplementation of T. chebula at 12 mg could improve rumen fermentation by reducing CH4 production and protozoa populations, thus improving in vitro gas production and VFA profiles.

    Lipoxygenase (LOX) inhibitors are the promising therapeutic target for treating a wide spectrum of inflammatory-related diseases such as cancer, asthma, lymphoma, leukemia, and autoimmune disorders. In the present study, the photochemical constituents and the anti-LOX potential of leaf galls of Terminalia chebula are evaluated to exemplify its further potential development as medicine. Extracts of T. chebula galls were tested for anti-LOX activity using linoleic acid as substrate and lipoxidase as an enzyme and also the total content of polyphenols with phytochemical analysis of the extract were determined. The presence of highest total phenolic and flavonoid content of 141 ± 2.2 mg of gallic acid equivalent/g d.w and 125 ± 1.4 mg of quercetin equivalent/g d.w and maximal LOX inhibitory activity (52.67%) at 800 μg/mL concentrations were identified in the ethanolic extracts of leaf galls of T.chebula. The higher LOX inhibitory activity was positively correlated to the high content of total polyphenols/flavonoids. The results of this study confirm the folklore use of T. chebula leaves gall extracts as a natural anti-inflammatory agent and justify its ethnobotanical use. Therefore, the results encourage the use of T. chebula leave gall extracts for medicinal health, functional food, and nutraceuticals applications. SUMMARY The present investigation demonstrated promising anti-LOX proper-ties of T. chebula leaves gall extracts. Presumably, these activities could be attributed in part to the polyphenolic features of the extract, as there was a strong correlation of higher LOX inhibiting activities with that of high total phenolic and flavonoid content in the methanolic leaf gall extracts of T. chebula. The results of this study confirm the folklore use of T. chebula leaves gall extracts as a natural anti-inflammatory agent and justify the ethnobotanical approach in the search for novel bioactive com-pounds.

The formation of silver nanoparticles was confirmed by Surface Plasmon Resonance (SPR) at 452 nm using UV-visible spectrophotometer. The reduction of silver ions to silver nanoparticles by T. chebula extract was completed within 20 min which was evidenced potentiometrically. Synthesised nanoparticles were characterised using UV-vis spectroscopy, Fourier transformed infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), transmission electron microscopy (TEM) and atomic force microscopy (AFM). The hydrolysable tannins such as di/tri-galloyl-glucose present in the extract were hydrolyzed to gallic acid and glucose that served as reductant while oxidised polyphenols acted as stabilizers. In addition, it showed good antimicrobial activity towards both Gram-positive bacteria (S. aureus ATCC 25923) and Gram-negative bacteria (E. coli ATCC 25922). Industrially it may be a smart option for the preparation of silver nanoparticles.

    Background Tannins extracted from immature fruits of Terminalia chebula Fructus Retz. are considered as effective components promoting the process of wound healing. The objective of this study is to explore the optimal extraction and purification technology (OEPT) of tannins, while studying the use of this drug in the treatment of a cutaneous wound of rat as well as its antibacterial effects. Methods The content of tannin extracts was measured by the casein method, and antibacterial ability was studied by the micro-dilution method in vitro. In wound healing experiment, animals in group Ⅰ, Ⅱ and Ⅲ were treated with vaseline ointment, tannin extracts (tannin content: 81%) and erythromycin ointment, respectively (5 mg of ointment were applied on each wound). To evaluate the process of wound healing, selected pharmacological and biochemical parameters were applied. Results After optimal extraction and purification, content of tannin extracts was increased to 81%. Tannin extracts showed the inhibition of Staphylococcus aureus and Klebsiella Pneumonia in vitro. After excision of wounds, on days 7 and 10, the percent of wound contraction of group Ⅱ was higher than that of group Ⅰ. After being hurt with wounds, on days 3, 7, and 10, the wound healing quality of group Ⅱ was found to be better than that of group Ⅰ in terms of granulation formation and collagen organization. After wound creation, on day 3, the vascular endothelial growth factor expression of group Ⅱ was higher than that of group Ⅰ. Conclusion The results suggest that tannin extracts from dried immature fruits of Terminalia chebula Fructus Retz. can promote cutaneous wound healing in rats, probably resulting from a powerful anti-bacterial and angiogenic activity of the extracts.

    Plant-based repellent formulations for honeybees play an important role in the bee management. For this purpose, the essential oil of an Indian medicinal plant, Terminalia chebula, commonly known as Myrobalan, was isolated for the first time. Hitherto unknown chemical constituents of the essential oil were determined by GC/MS. The repellent activity of formulations of the essential oil, tested towards the Indian honeybee Apis florea, was found to be dose dependent. The repellency (DeltaR) increased with the concentration of essential oil in the formulations, reaching a maximum for the formulation containing 50 mg/ml of oil. A further increase in the oil concentration was found to reduce the DeltaR. The screening of formulations of the major essential-oil components identified indicated that formulations of furfural, 5-methylfurfural, tetradecanoic acid, palmitic acid, and oleic acid elicited no response in honeybees. In contrast, the formulations of phenylacetaldehyde were repellent, while those of ethyl cinnamate were attractant. These findings might be an asset for beekeepers to improve the bee management. Attractant formulations are effective to attract bees to the desired areas, thus improving the efficiency of pollination. Repellent formulations are used to repel honeybees, especially when toxic insecticides are sprayed on the fields.

    In the present study, two chloroform extracts of fruits of Terminalia chebula viz. “CHL1” and “CHL 2” prepared by maceration and sequential method respectively was compared for their antioxidant efficacy and phenolic content. The extraction procedure of plant material plays an important role in the activity of phytochemicals. Also, the assessment of antioxidant capacity of phytochemicals cannot be executed precisely by any single method due to complex nature of phytochemicals as multiple reaction characteristics and mechanisms can be involved. So, no single assay could accurately reflect comparison in a mixed or complex system. Therefore in the present study the comparison of extracts was done by using most widely used assays viz. DPPH, deoxyribose, reducing power, chelating power and lipid peroxidation assay. Furthermore, the UV-Vis spectrum of both extracts and the correlation between total phenolic content was examined in order to give an orientation to the search of phytochemicals responsible for their activity. From the results, it was concluded that antioxidant activity and phenolic compounds were predominant in the ‘CHL 2’ prepared by sequential method.

    The objectives of this study were to determine phytochemical compositions, chemiluminescence antioxidant activities, and neuroprotective effects on PC12 cells for water, methanol, and 95% ethanol extracts of the air-dried fruit of Terminalia chebula Retzius. The water extract afforded the greatest yield, and total phenolic and tannin content. The methanol extract yielded the greatest total triterpenoid content. Based on four chemiluminescence antioxidant assays, the three extracts showed various degrees of antioxidant activity. The methanol extract showed good antioxidant activity based on the horseradish peroxidase-luminol-hydrogen peroxide (H2O2) assay. The water extract appeared to have good antioxidant activities in cupric sulfate-Phen-Vc-H2O2 and luminol-H2O2 assays. Pyrogallol-luminol assay showed the 95% ethanol extract to have good antioxidant activity. The methanol and water extracts presented neuroprotective activities on H2O2-induced PC12 cell death at 0.5–5.0 μg/mL. Further investigations are necessary to verify these activities in vivo.

    Plants have been an important source for discovery of anticancer compounds. With the current decline in the number of new molecular entities from the pharmaceutical industry, novel anticancer agents are being sought from traditional medicines; therefore the anticancer efficacy of many plants that are used in traditional medicine is yet to be verified. The objective of the study was to evaluate the cytotoxic potential of ethanolic leaf gall extract of Terminalia chebula are evaluated against buffalo rat liver 3A, MCF-7 (Human mammary gland adenocarcinoma) and A-549 (Human lung cancer) cell lines. The cytotoxic effect of the ethanolic extract was evaluated by MTT assay. The extract was potent and effective in inducing cytotoxic effects in all the cell lines with an IC50 value of 305.18 ± 1.7 μg/mL, 643.13 ± 4.2 μg/mL, and 208.16 ± 3.7 μ/mL, respectively. The extract was more effective against A549 cell lines when compared to others. The presences of phenolics, triterpenoids, and flavonoids were identified in the extract. The extract showed total phenolic and flavonoid content of 478 ± 2.2 mg of gallic acid equivalent/g d.w and 538 ± 1.4 mg of quercetinequivalent/g d.w, respectively. This higher content of total phenolics and flavonoids found in the ethanolic extract was directly associated to higher cytotoxicity activity. Conclusion: The ethanolic leaf gall extract of T. chebula showed effective cytotoxic activities; which might be attributed to the phenolics/flavonoids present in higher concentration. Future work will be interesting to know the chemical composition of the extract and also better understand the mechanism of action of the constituents present in the extract to develop it as drug for therapeutic application. SUMMARY The present investigation establishes the anticancer activities of T. chebula leaf gall extracts on BRL3A, MCF-7, and A-549 cells. Presumably, these activities could be attributed in part to the phenolics/flavanoids features of the

    A separation method based on high-speed counter-current chromatography (HSCCC) has been established for the isolation and preparation of gallic acid from the ethanol extract of Terminalia chebula Retz. After comparing five kinds of solvent protocols of HSCCC, the two-phase system of n-hexane-ethyl acetate-methanol-water (1:5:1:5, v/v/v/v) was finally chosen as the operating solvent of HSCCC for the separation of gallic acid, in which the lower phase was used as the mobile phase and the upper phase as stationary phase. The detection in the experiments was performed with an ultraviolet detector at 254 nm. Under the conditions of rotation speed of 850 r/min, lower phase flow rate of 2 mL/min, four peaks (I/II/III/IV) were displayed on HSCCC chromatogram. Among them, only peak III contained a large amount of gallic acid (about 96. 40%), which was confirmed by electrospray ionization mass spectrometry (ESI-MS) and high performance liquid chromatographic (HPLC) analysis. As much as 8. 6 mg of gallic acid was obtained from 100 mg of the ethanol extract of Terminalia chebula Retz., indicating the method is simple, robust and efficient for the preparation of gallic acid.

    In the present study Terminalia chebula was used as an eco-friendly natural colorant for sustainable textile coloration of woolen yarn with primary emphasis on thermodynamic and kinetic adsorption aspects of dyeing processes. Polyphenols and ellagitannins are the main coloring components of the dye extract. Assessment of the effect of pH on dye adsorption showed an increase in adsorption capacity with decreasing pH. Effect of temperature on dye adsorption showed 80 °C as optimum temperature for wool dyeing with T. chebula dye extract. Two kinetic equations, namely pseudo first-order and pseudo second-order equations, were employed to investigate the adsorption rates. Pseudo second-order model provided the best fit (R (2) = 0.9908) to the experimental data. The equilibrium adsorption data were fitted by Freundlich and Langmuir isotherm models. The adsorption behavior accorded well (R (2) = 0.9937) with Langmuir isotherm model. Variety of eco-friendly and sustainable shades were developed in combination with small amount of metallic mordants and assessed in terms of colorimetric (CIEL(∗) a (∗) b (∗) and K/S) properties measured using spectrophotometer under D65 illuminant (10° standard observer). The fastness properties of dyed woolen yarn against light, washing, dry and wet rubbing were also evaluated.

    Background and Aims: To evaluate analgesic activity and safety of single oral dose (1000 mg) of Terminalia chebula using a mechanical pain model in healthy human volunteers. Material and Methods: Twelve healthy volunteers were randomized to receive either single oral dose of 2 capsules of T. chebula 500 mg each or identical placebo capsules in a double-blinded manner. Mechanical pain was assessed using Ugo basile analgesy meter (Randall–Selitto test) before and 3 h after administration of test drug. The parameters evaluated were pain threshold force and time; pain tolerance force and time. A washout period of 1-week was given for crossover between active drug and placebo. Results: Terminalia chebula significantly increased the mean percentage change for pain threshold force and time, and pain tolerance force and time compared to placebo (P < 0.001). The mean percentage change for pain threshold force and time (20.8% and 21.0%) was increased more than that of pain tolerance force and time (13.4% and 13.4%). No adverse drug reaction was reported with either of the study medications during the study period. Conclusion: T. chebula significantly increased pain threshold and pain tolerance compared to placebo. Both the study medications were well tolerated. Further multiple dose studies may be needed to establish the analgesic efficacy of the drug in patients suffering from osteoarthritis, rheumatoid arthritis and other painful conditions.

    Death receptor (DR) ligation elicits two different modes of cell death (necroptosis and apoptosis) depending on the cellular context. By screening a plant extract library from cells undergoing necroptosis or apoptosis, we identified a water extract of Terminalia chebula (WETC) as a novel and potent dual inhibitor of DR-mediated cell death. Investigation of the underlying mechanisms of its anti-necroptotic and anti-apoptotic action revealed that WETC or its constituents (e.g., gallic acid) protected against tumor necrosis factor-induced necroptosis via the suppression of TNF-induced ROS without affecting the upstream signaling events. Surprisingly, WETC also provided protection against DR-mediated apoptosis by inhibition of the caspase cascade. Furthermore, it activated the autophagy pathway via suppression of mTOR. Of the WETC constituents, punicalagin and geraniin appeared to possess the most potent anti-apoptotic and autophagy activation effect. Importantly, blockage of autophagy with pharmacological inhibitors or genetic silencing of Atg5 selectively abolished the anti-apoptotic function of WETC. These results suggest that WETC protects against dual modes of cell death upon DR ligation. Therefore, WETC might serve as a potential treatment for diseases characterized by aberrantly sensitized apoptotic or non-apoptotic signaling cascades. PMID:27117478

    We aimed to identify the hepatoprotective effects of Terminalia chebula water extract (TCW) and its corresponding pharmacological actions using C57/BL6 mice model of tert-butylhydroperoxide-(t-BHP-) induced acute liver injury. Mice were orally administered with TCW (0, 50, 100, or 200 mg/kg) or gallic acid (100 mg/kg) for 5 days before t-BHP (2.5 mM/kg) injection. Liver enzymes, histopathology, oxidative stress parameters, antioxidant components, and inflammatory cytokines were examined 18 h after t-BHP injection. t-BHP injection caused dramatic elevation of serum AST, ALT, and LDH level, while TCW pretreatment notably attenuated these elevations. Inflammatory cytokines including TNF-α, IL-1β, and IL-6 were notably increased in hepatic tissues, and then these were efficiently attenuated by TCW pretreatment. t-BHP injection notably increased malondialdehyde, total reactive oxygen species, and nitric oxide in the liver tissue, while it markedly dropped the antioxidant activities including total antioxidant capacity, total glutathione contents, glutathione peroxidase, superoxide dismutase, and catalase. TCW pretreatment remarkably ameliorated these alterations, and these effects were relevant to gene expressions. Histopathological examinations supported the above findings. Collectively, these findings well prove that TCW beneficially prevents acute and severe liver injury and clarify its corresponding mechanisms involved in the inhibition of oxidative stress and inflammatory cytokines.

    Terminalia, a large genus of Combretaceae, is distributed in Tropical Asia, Africa, and America. Some Terminalia plants are used in folk medicine because they possess powerful medicinal properties. Dried fruits of Terminalia bellirica and Terminalia chebula are used as the main ingredient in Triphala, a famous polyherbal formulation in Ayurvedic medicine and Thai folk medicine, because of their laxative, detoxifying, and rejuvenating effects. To clarify the phylogenetic relationships of medicinal Terminalia species (T. bellirica, T. chebula, and T. catappa) and authenticate their crude drugs, "Samo" and Triphala, nucleotide sequencing alignments in the internal transcribed spacer one-two (ITS 1-2) regions of Terminalia plants collected in Thailand were performed. The amplified fragments of Terminalia species were approximately 800 bp in length. To compare these sequences and DDBJ registered data, a molecular phylogenetic tree was constructed. Phylogenetic analysis clearly separated the sequences into two groups: Asian Terminalia and African Terminalia with some exceptions. In the analyzed sequences, the length of the ITS1-5.8S-ITS2 region was 674 bp in T. chebula, and 677 bp in T. bellirica and T. catappa. Eighty-one single nucleotide polymorphisms (SNPs) and nine insertion-deletions (indels) were observed, and the nucleotide sequences of this region showed species-specific sequences. Based on these differences, polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and amplification refractory mutation system (ARMS) were applied to identify medicinal Terminalia species. Moreover, the ARMS method was chosen for fingerprinting analysis of Samo crude drugs and Triphala formulations because it was a fast, cost-effective, and reproducible approach. PMID:27040622

    Aims In the presence of oxygen, most of the synthesized pyruvate during glycolysis in the cancer cell of solid tumors is released away from the mitochondria to form lactate (Warburg Effect). To maintain cell homeostasis, lactate is transported across the cell membrane by monocarboxylate transporters (MCTs). The major aim of the current investigation is to identify novel compounds that inhibit lactate efflux that may lead to identifying effective targets for cancer treatment. Study Design In this study, 900 ethanol plant extracts were screened for their lactate efflux inhibition using neuroblastoma (N2-A) cell line. Additionally, we investigated the mechanism of inhibition for the most potent plant extract regarding monocarboxylate transporters expression, and consequences effects on viability, growth, and apoptosis. Methodology The potency of lactate efflux inhibition of ethanol plant extracts was evaluated in N2-A cells by measuring extracellular lactate levels. Caspase 3- activity and acridine orange/ethidium bromide staining were performed to assess the apoptotic effect. The antiproliferative effect was measured using WST assay. Western blotting was performed to quantify protein expression of MCTs and their chaperone CD147 in treated cells lysates. Results Terminalia chebula plant extract was the most potent lactate efflux inhibitor in N2-A cells among the 900 - tested plant extracts. The results obtained show that extract of Terminalia chebula fruits (TCE) significantly (P = 0.05) reduced the expression of the MCT1, MCT3, MCT4 and the chaperone CD147. The plant extract was more potent (IC50 of 3.59 ± 0.26 μg/ml) than the MCT standard inhibitor phloretin (IC50 76.54 ± 3.19 μg/ml). The extract also showed more potency and selective cytotoxicity in cancer cells than DI-TNC1 primary cell line (IC50 7.37 ± 0.28 vs. 17.35 ± 0.19 μg/ml). Moreover, TCE Inhibited N2-A cell growth (IG50 = 5.20 ± 0.30 μg/ml) and induced apoptosis at the 7.5 μg/ml concentration

    Objectives To evaluate the efficacy and tolerability of standardized aqueous extracts of Terminalia chebula and Terminalia bellerica versus febuxostat and placebo on reduction in serum uric acid levels in subjects with hyperuricemia. Materials and methods A total of 110 eligible subjects with hyperuricemia were enrolled and randomized to either of the five treatment groups – T. chebula 500 mg twice a day (BID), T. bellerica 250 mg BID, T. bellerica 500 mg BID, placebo BID, and febuxostat 40 mg once daily plus an identical placebo – for a duration of 24 weeks. Serum uric acid levels were measured at baseline and at the end of 4, 8, 12, 16, 20, and 24 weeks. Statistical analysis was done using GraphPad Prism Software 4. Results and interpretation All active treatment groups showed a reduction in serum uric acid levels compared to baseline and placebo. Significant reduction in mean serum uric acid levels started as early as 4 weeks following treatment, compared to baseline, with T. bellerica (500 and 250 mg), febuxostat (P<0.001), and T. chebula 500 mg (P<0.01); an increase in serum uric acid levels was seen with placebo (P<0.05). The serum uric acid levels became steady after 16 weeks of treatment and remained the same until the end of 24 weeks. The reduction of serum uric acid levels in the T. bellerica 500 mg group was nearly twice that of the T. chebula 500 mg group as well as T. bellerica 250 mg group at all time points. T. bellerica 500 mg reduced serum uric acid levels from 8.07±0.87 to 5.78±0.25 compared to febuxostat, which reduced serum uric acid levels from 8.53±0.97 to 4.28±0.67 (P<0.001) at the end of 24 weeks. The efficacy of T. bellerica appeared to be dose dependent. All the formulations were well tolerated. Conclusion T. bellerica has the potential for treating hyperuricemia as it was devoid of any serious adverse effects in the present study. Further studies are needed to confirm this potential.

    The galls of Terminala chebula (Gaertn.) Retz. (Combretaceae) are used for the treatment of various diseases in folk medicine and has been found to posses anti-inflammatory, anti-bacterial, anti-helmintic, anti-tyrosinase, and anti-aging activities. Considering the ethano-botanical and diverse pharmacological applications of galls of T. chebula, in this study, we investigate the possible toxic effects of different gall extracts of T. chebula by Brine shrimp (Artemia salina) toxicity assay. The cytotoxicity test of leaf gall extracts (petroleum ether, chloroform, ethanol, and aqueous) of T. chebula was evaluated by Brine shrimp (A. salina) toxicity assay, which is based on the ability to kill laboratory cultured Artemia nauplii (animals eggs) and also total content of polyphenols, flavonoids with other qualitative phytochemical analysis of the extract were determined. It was observed that the petroleum ether extract was virtually nontoxic on the shrimps, and exhibited very low toxicity with LC50 value of 4356.76 μg/ml. Furthermore, the chloroform extract exhibited very low toxicity, giving LC50 value of 1462.2 μg/ml. On the other hand, the ethanol extract was very toxic to brine shrimps with LC50 value of 68.64 μg/ml. The ethanol extract had the highest total phenolic and flavonoid content of 136 ± 1.5 mg of gallic acid equivalent/g d.w and 113 ± 1.6 mg of quercetin equivalent/g d.w, respectively. The higher toxicity effect was positively correlated to the high content of total polyphenols/flavonoids in the extract. This significant lethality of different extracts to brine shrimp is an indicative of the presence of potent cytotoxic components which warrants further investigation. SUMMARY The present study investigates the toxicity effect of different extracts of galls of T. chebulla, which would serve as an index for formulation of drugs for treatment of various diseases. Presumably, these activities could be attributed in part to the polyphenolic features of

    Context Chebulae Fructus is used as an herbal remedy for diarrhoea in traditional Chinese medicine. However, there is no scientific evidence to support its antidiarrhoeal activity. Objective This study evaluates the antidiarrhoeal properties of Chebulae Fructus aqueous extract (CFAE) and determines the active fraction. Materials and methods The antidiarrhoeal effect of CFAE (200-800 mg/kg) was investigated by determining the wet dropping, intestinal transit in BALB/c mice and enteropooling in Wister rats. The protective effects of the CFAE on the intestinal and liver were tested by histopathological analyses. The antidiarrhoeal fraction was determined by castor oil-induced diarrhoea and its main constituents were identified by HPLC-ESI-MS. Results The extract at doses of 200, 400 and 800 mg/kg reduced the diarrhoea by 9.1, 40.0 and 58.2% and inhibited intestinal transit by 18.3, 24.1 and 35.7%, respectively. Additionally, the CFAE (200, 400 and 800 mg/kg) decreased the volume of enteropooling by 47.1, 58.8 and 64.7%, respectively. Mice treated with castor oil presented morphological alterations in the small intestine and the liver. However, the lesions of mice treated with CFAE were alleviated. Moreover, the ethyl acetate fraction was the active fraction of CFAE, the fraction (41.7, 83.4 and 166.8 mg/kg) reduced the diarrhoea by 9.1, 38.2 and 54.5%, respectively. The major components of the ethyl acetate fraction were tannins, including gallic acid, 3, 4, 6-tri-O-galloyl-β-d-Glc, corilagin and ellagic acid according to the HPLC-ESI-MS analysis. Conclusion The CFAE possessed antidiarrhoeal property and the ethyl acetate fraction was its main active fraction.

    There is documented evidence of the use of Terminalia chebula for various ailments in the Ayurvedic literature. The extract has been shown to possess glucose lowering activity and to improve insulin sensitivity in animal models of type 2 diabetes mellitus. The present study was carried out to study the dose response relationship of this extract in a rat model of metabolic syndrome. Six groups of rats were fed a high fructose diet (HFD) for a period of 20 days to induce metabolic syndrome. Three doses of fruit extract of T. chebula 50, 100 and 200 mg/kg were administered orally and pioglitazone 2.7 mg/kg was used as a positive control. Blood samples were collected at days 0, 20 and 40 from the tail vein. Systolic blood pressure (SBP) was measured using the tail cuff method and an oral glucose tolerance test (OGTT) was done on the day of blood collection. Administration of HFD for 20 days significantly increased fasting blood glucose (FBG), SBP and the area under the curve of OGTT. On day 40 the FBG in the 50, 100 and 200 mg/kg group was 97.33 +/- 5.82 (NS), 86.83 +/- 5.08 (p = 0.038) and 85.67 +/- 6.74 (p = 0.15), respectively. These results show that the fruit extract of T. chebula exerts a significant and dose-dependent glucose lowering effect in the rat model of metabolic syndrome. PMID:19475706

    Avian pathogenic Escherichia coli (APEC) causes inflammation in multiple organs of chickens called avian colibacillosis, and results in serious economic loss to the chicken industry. Polyphenolic compounds possess a wide range of physiological activities that may contribute to their beneficial effects against inflammation-related diseases. In this study, the curative effect and mechanism of action of the polyphenolic extracts from Punica granatum L. and Terminalia chebula Retz. in chickens challenged with APEC were studied. Specific-pathogen-free white Leghorn chickens (males, 21-d old) were challenged with APEC and then given oral administration of extracts of P. granatum and T. chebula. The extracts decreased the morbidity and inflammation induced by APEC. Data from quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay showed that the extracts of P. granatum and T. chebula polyphenols (GCP) reversed the over-expression genes of the Toll-like receptor (TLR) 2, 4, and 5, down-regulated the activation of nuclear factor-kappa B signal transduction pathways, and inhibited the production of pro-inflammatory cytokines. Naturally occurring GCP may be a potential alternative medicine for the prevention or treatment of avian colibacillosis.

    In the present paper, the phenol removal from wastewater was investigated using agri-based adsorbent: Terminalia chebula-activated carbon (TCAC) produced by carbonization of Terminalia chebula (TC) in air-controlled atmosphere at 600 °C for 4 h. The surface area of TCAC was measured as 364 m2/g using BET method. The surface characteristic of TCAC was analyzed based on the value of point of zero charge. The effect of parameters such as TCAC dosage, pH, initial concentration of phenol, time of contact and temperature on the sorption of phenol by TCAC was investigated using conventional method and Taguchi experimental design. The total adsorption capacity of phenol was obtained as 36.77 mg/g using Langmuir model at the temperature of 30 °C at pH = 5.5. The maximum removal of phenol (294.86 mg/g) was obtained using Taguchi's method. The equilibrium study of phenol on TCAC showed that experimental data fitted well to R-P model. The results also showed that kinetic data were followed more closely the pseudo-first-order model. The results of thermodynamic study showed that the adsorption of phenol on TCAC was spontaneous and an exothermic in nature.

    Plants of the genus Terminalia are amongst the most widely used plants for traditional medicinal purposes worldwide. Many species are used for their antibacterial, antifungal, antiprotozoal, antiviral, antidiarrhoeal, analgesic, antimalarial, antioxidant, antiinflammatory and anticancer activities. Wound healing and cardiovascular effects have also been credited to some species. Many Terminalia species have multiple beneficial effects for multiple diseases and ailments. Indeed, the Indian species Terminalia chebula is known as the king of plants in Ayurveda due to its broad range of medicinal uses. However, apart from the reported ethnopharmacological uses of many Terminalia species, surprisingly few studies have rigorously examined this important genus for their medical properties/mechanisms and phytochemistry. This is likely due to the high tannin content common to many Terminalia species and the perception that these tannins may be responsible for much of their beneficial properties. As the complexities of tannins make them poor candidates for drug design, most interest in Terminalia species has been for their pharmacognostic and nutraceutical value and they have often been overlooked as potentials for drug discovery. However, recent reports have identified many other interesting phytochemicals and demonstrated that these may be responsible for several of the reported bioactivities of the Terminalia species used in traditional medicinal systems. The last decade has seen a large increase in the number of studies into the use of Terminalia species as therapeutic agents. Several species used in Ayurvedic medicine (Terminalia arjuna, Terminalia bellerica, Terminalia catappa, T. chebula) in particular have received much recent attention. Similarly, recent reports have also highlighted the medicinal potential of species from Africa, Australia and the Americas.

    Background: Various parts of three Terminalia species, namely, Terminalia arjuna (stem bark), Terminalia bellirica (fruit), and Terminalia chebula (fruit) are widely known for their therapeutic principles and other commercial values. However, stem bark of T. bellirica and T. chebula along with Terminalia tomentosa are reported as adulterants of T. arjuna. Correct botanical identification is very critical for safe and effective herbal drugs. DNA-based identification approaches are advancing the conventional methods and sometime proved more beneficial. Objective: The purpose of the study was to develop polymerase chain reaction (PCR) method using internal transcribed spacer (ITS) region to ascertain the identity of T. arjuna herbal material as well as detection of mixing of other three Terminalia species. Materials and Methods: DNA from stem barks samples were isolated and subjected to ITS region amplification and sequencing. Sequences were compared for polymorphic nucleotides determination to develop species-specific primers. Final primers were selected on the basis of in silico analysis and experimentally validated. PCR assays for botanical identification of Terminalia species were developed. Sensitivity testing and assay validation were also performed. Results: The PCR assays developed for Terminalia species were resulted in definite amplicons of the corresponding species. No cross-reactivity of the primers was detected. Sensitivity was found enough to amplify as low as 2 ng of DNA. Mixing of DNA in various concentrations for validation also proved the sensitivity of assay to detect original botanicals in the mixture. The developed methods proved very specific and sensitive to authenticate Arjuna bark to develop evidence-based herbal medicines. SUMMARY Internal transcribed spacer-based species-specific polymerase chain reaction.(PCR) assays were developed to authenticate Terminalia arjuna stem bark and to identify substitution/adulteration of Terminalia bellirica

    This study presents an efficient strategy for separation of three phenolic compounds with high molecular weight from the crude extract of Terminalia chebula Retz. by ultrasound-assisted extraction and high-speed counter-current chromatography. The ultrasound-assisted extraction conditions were optimized by response surface methodology and the results showed the target compounds could be well enriched under the optimized extraction conditions. Then the crude extract was directly separated by high-speed counter-current chromatography without any pretreatment using n-hexane/ethyl acetate/methanol/water (1:7:0.5:3, v/v/v/v) as the solvent system. In 180 min, 13 mg of A, 18 mg of B, and 9 mg of C were obtained from 200 mg of crude sample. Their structures were identified as Chebulagic acid (A, 954 Da), Chebulinic acid (B, 956 Da), and Ellagic acid (C) by (1) H NMR spectroscopy. PMID:26864462

    Background Burgeoning antibiotic resistance in Pseudomonas aeruginosa has necessitated the development of anti pathogenic agents that can quench acylhomoserine lactone (AHL) mediated QS with least risk of resistance. This study explores the anti quorum sensing potential of T. chebula Retz. and identification of probable compounds(s) showing anti QS activity and the mechanism of attenuation of P. aeruginosa PAO1 virulence factors. Methods and Results Methanol extract of T. chebula Retz. fruit showed anti QS activity using Agrobacterium tumefaciens A136. Bioactive fraction (F7), obtained by fractionation of methanol extract using Sephadex LH20, showed significant reduction (p<0.001) in QS regulated production of extracellular virulence factors in P. aeruginosa PAO1. Biofilm formation and alginate were significantly (p<0.05) reduced with enhanced (20%) susceptibility to tobramycin. Real Time PCR of F7 treated P. aeruginosa showed down regulation of autoinducer synthase (lasI and rhlI) and their cognate receptor (lasR and rhlR) genes by 89, 90, 90 and 93%, respectively. Electrospray Ionization Mass Spectrometry also showed 90 and 64% reduction in the production of 3-oxo-C12HSL and C4HSL after treatment. Decrease in AHLs as one of the mechanisms of quorum quenching by F7 was supported by the reversal of inhibited swarming motility in F7-treated P. aeruginosa PAO1 on addition of C4HSL. F7 also showed antagonistic activity against 3-oxo-C12HSL-dependent QS in E. coli bioreporter. C. elegans fed on F7-treated P. aeruginosa showed enhanced survival with LT50 increasing from 24 to 72 h. LC-ESI-MS of F7 revealed the presence of ellagic acid derivatives responsible for anti QS activity in T. chebula extract. Conclusions This is the first report on anti QS activity of T. chebula fruit linked to EADs which down regulate the expression of lasIR and rhlIR genes with concomitant decrease in AHLs in P. aeruginosa PAO1 causing attenuation of its virulence factors and enhanced

    Wound is defined as the loss of breaking cellular and functional continuity of the living tissues. Management of wounds is frequently encountered with different problems. Drug resistance and toxicity hindered the development of synthetic antimicrobial agents with wound healing activity. Many plants with potent pharmacological activities may offer better treatment options viz. Terminalia chebula, Terminalia bellirica and Phyllanthus emblica formulations have shown healing activities on wounds.The present study was planned to investigate the wound healing activity of Terminalia catappa on excision wound model in rats. Ointment was prepared by using bark extract of Terminalia catappa in soft paraffin and preservative. Wistar albino rats (200-250 gm) of either sex were used in the present study. A circular wound of 2 cm in diameter was made on the depilated dorsal thoracic region of the rats under ether anesthesia in aseptic conditions. The ointment was applied for 18 days and percent wound closure observed along with the parameters viz. Epithelization, granuloma weight and scar formation. Animals were observed on 3rd, 6th, 9th, 12th, 15th and 18th post-wounding day.Wound healing activity was compared with that of control and Betadine ointment as standard drug. Animals treated with Terminalia catappa ointment exhibited 97% reduction in wound area as compared to the control animals (81%). Ointment treated wounds were found to induce epithelization faster compared to the control. In conclusion, Terminalia catappa ointment promotes significant wound healing in rats and further evaluation of this activity in humans is suggested.

    The bark of Terminalia arjuna is known for its heart-health benefits in ayurvedic literature. This has been further supported by in vivo studies on animal and human volunteers. But there is no detailed study on identification of the active ingredients such as polyphenols. Polyphenols possesses antioxidant properties and are well-known health actives, it is important to characterise polyphenols in Terminalia arjuna. Aqueous extract of Terminalia arjuna bark was analysed for its composition and molecular weight distribution by dialysis. Compositional analysis revealed that it has 44% polyphenols and dialysis study showed that 70% of the polyphenols have molecular weight greater than 3.5 kDa. High performance liquid chromatography and liquid chromatography–mass spectrometry analysis of Terminalia arjuna, confirmed that it contains flavon-3-ols such as (+)-catechin, (+)-gallocatechin and (−)-epigallocatechin. Phenolic acids such as gallic acid, ellagic acid and its derivatives were also found in Terminalia arjuna extract. Ellagic acid derivatives were isolated and their spectral studies indicated that isolated compounds were 3-O-methyl-ellagic acid 4-O-β-D-xylopyranoside, ellagic acid and 3-O-methyl ellagic acid 3-O-rhamnoside. Hydrolysis and thiolysis studies of high molecular weight polyphenols indicated that they are proanthocyanidins. Given these results, it may be possible to attribute the heart-health effects of Terminalia arjuna to these polyphenols which may be responsible for the endothelial benefit functions like tea.

    In this work we investigated the antitussive activity of the medicinal tree Terminalia arjuna. We used the stem bark for extraction and preparation of water extracted isolate and its two fractions: acetone-soluble (TA-S) and acetone precipitated (TA-P) fraction. The presence of a pectic arabinogalactan was confirmed in TA-P fraction by chromatographic and spectroscopic analysis. The antitussive activity of samples was assessed after oral administration in a dose of 50 mg.kg(-1) in healthy guinea pigs, in which cough was elicited by inhalation of citric acid (0.3 mol/L) in body plethysmograph. The water extracted isolate showed a significant ability to decrease the number of cough efforts by 64.2 %; the antitussive activity on par with that of codeine phosphate. The TA-P fraction showed the antitussive activity of 54.8 %. In contrast, TA-S fraction had only a mild antitussive activity. No changes in in vivo airway resistance were noted. We conclude that arabinogalactan is an essential component of Terminalia arjuna that underlies its antitussive action. PMID:27334729

    ABSTRACT Purpose: For most cases, urolithiasis is a condition where excessive oxalate is present in the urine. Many reports have documented free radical generation followed by hyperoxaluria as a consequence of which calcium oxalate (CaOx) deposition occurs in the kidney tissue. The present study is aimed to exam the antilithiatic potency of the aqueous extract (AE) of Terminalia arjuna (T. arjuna). Materials and Methods: The antilithiatic activity of Terminalia arjuna was investigated in vitro nucleation, aggregation and growth of the CaOx crystals as well as the morphology of CaOx crystals using the inbuilt software ‘Image-Pro Plus 7.0’ of Olympus upright microscope (BX53). Antioxidant activity of AE of Terminalia arjuna bark was also determined in vitro. Results: Terminalia arjuna extract exhibited a concentration dependent inhibition of nucleation and aggregation of CaOx crystals. The AE of Terminalia arjuna bark also inhibited the growth of CaOx crystals. At the same time, the AE also modified the morphology of CaOx crystals from hexagonal to spherical shape with increasing concentrations of AE and reduced the dimensions such as area, perimeter, length and width of CaOx crystals in a dose dependent manner. Also, the Terminalia arjuna AE scavenged the DPPH (2, 2-diphenyl-1-picrylhydrazyl) radicals with an IC50 at 13.1µg/mL. Conclusions: The study suggests that Terminalia arjuna bark has the potential to scavenge DPPH radicals and inhibit CaOx crystallization in vitro. In the light of these studies, Terminalia arjuna can be regarded as a promising candidate from natural plant sources of antilithiatic and antioxidant activity with high value. PMID:26689519

    Phytochemical investigation of the ethyl acetate-soluble fraction of stem bark extract of an African medicinal plant Terminalia brownii led to the isolation of a new oleanane-type triterpenoid, along with seven known triterpenoids, seven ellagic acid derivatives, and 3-O-β-D-glucopyranosyl-β-sitosterol. The new compound was identified using spectroscopic methods, notably 1D- and 2D NMR, as 3β,24-O-ethylidenyl-2α,19α-dihydroxyolean-12-en-28-oic acid. The isolated compounds were evaluated for their antimicrobial and antiplasmodial activities. Two compounds with a galloyl group (4 and 6) were found to be active against chloroquine sensitive (D6) and chloroquine resistant (W2) strains of Plasmodium falciparum, whereas three ellagic acid derivatives (5–7) were found active against three species of fungi and one species of bacteria.

    This work investigates Terminalia catappa leaf-extract performance on mild steel corrosion in 0.5 M hydrochloric acid (HCl). Electrochemical linear-sweep-voltametry (LSV) and gravimetric techniques were employed for assessing the mild steel corrosion in the HCl test-environment of immersion having different concentrations of the leaf-extract. Results showed that all the concentrations of the Terminalia catappa leaf-extract employed inhibited mild steel corrosion from the electrochemical (potentiodynamic) and the gravimetric considerations. Also, corrosion rate from LSV exhibited excellent correlation (R = 95.77%, Nash-Sutcliffe Efficiency (NSE) = 91.72% and p-value = 0.02383) with linear function of the corrosion rate from gravimetric method, for the leaf-extract concentrations employed. From the experimental model, 6 g/L Terminalia catappa exhibited optimal inhibition efficiency, η = 78.07%, while 8 g/L Terminalia catappa was predicted as optimally effective, η = 75.41%, by the correlation fitting model, at inhibiting mild steel corrosion in the medium. However, adsorption isotherm modelling showed that the experimental gravimetric, experimental potentiodynamic and predicted potentiodynamic data exhibited agreements in following the Langmuir adsorption isotherm. All the three data models indicated favourable adsorption and identified physisorption as the prevalent adsorption mechanism of Terminalia catappa leaf-extract on mild steel immersed in the 0.5 M HCl medium.

    2014-01-01

    Terminalia arjuna, commonly known as arjuna, belongs to the family of Combretaceae. Its bark decoction is being used in the Indian subcontinent for anginal pain, hypertension, congestive heart failure, and dyslipidemia, based on the observations of ancient physicians for centuries. The utility of arjuna in various cardiovascular diseases needs to be studied further. Therefore, the present review is an effort to give a detailed survey of the literature summarizing the experimental and clinical studies pertinent to arjuna in cardiovascular disorders, which were particularly performed during the last decade. Systematic reviews, meta-analyses, and clinical studies of arjuna were retrieved through the use of PubMed, Google Scholar, and Cochrane databases. Most of the studies, both experimental and clinical, have suggested that the crude drug possesses anti-ischemic, antioxidant, hypolipidemic, and antiatherogenic activities. Its useful phytoconstituents are: Triterpenoids, β-sitosterol, flavonoids, and glycosides. Triterpenoids and flavonoids are considered to be responsible for its beneficial antioxidant cardiovascular properties. The drug has shown promising effect on ischemic cardiomyopathy. So far, no serious side effects have been reported with arjuna therapy. However, its long-term safety still remains to be elucidated. Though it has been found quite useful in angina pectoris, mild hypertension, and dyslipidemia, its exact role in primary/secondary coronary prevention is yet to be explored. PMID:25379463

    Terminalia belerica seeds, collected from Indian forests, were explored as an alternate bioresource for biodiesel synthesis. The oil yield of T. belerica seed is about 31% (dry weight basis). The fatty acid profile of T. belerica seed oil shows predominance of oleic acid (C(18:1)) glycerides (61.5%) along with linoleic (18.5%) and palmitic (11.6%) glycerides. Oil was extracted and evaluated for physico-chemical properties vis-a-vis jatropha, sunflower, soybean and rapeseed oil. T. belerica oil was transesterified with methanol in the presence of sodium methoxide catalyst. The physico-chemical properties of synthesized methyl ester were compared to jatropha, sunflower, soybean and rapeseed methyl esters as per ASTM D-6751 specification of biodiesel. Synthesized T. belerica methyl ester was also blended in diesel at 5-20% ratios and evaluated for key physico-chemical properties as per IS 1460 specification and found to meet in properties evaluated as per specific standards. The study revealed the possibility of T. belerica seed oil as potential resource of biodiesel.

    Soxhlet extractor was used in the extraction of oil from milled seeds of Terminalia catappa using petroleum ether (40-60 degrees ). The optimal oil yield was 56.71+/-1.66% with a viscosity of 40.79+/-1.05 centipoises. Other parameters of the oil were found as follows; specific gravity-0.9248, refractive index-1.4646, acid value-3.35, peroxide value-8.6, saponification value-166.2, and unsaponifiable matter-1.46. The crude oil extract was water-degummed, bleached and deodorized to generate what we called refined oil. Autoxidation of the crude and refined T. catappa oil extract was done at five different temperatures of 0+/-0.1 degrees , 20+/-0.1 degrees , 40+/-0.1 degrees , 60+/-0.1 degrees and 80+/-0.1 degrees and also in the presence of pure alpha-tocopherol at a concentration of 1.0% (w/v) by measuring peroxide value variations over 96 h. In all evaluations, the refined oil exhibited lower tendency towards autoxidation but not at temperatures above 60+/-0.1 degrees . The use of Arrhenius equation revealed generally very low activation energies of 0.0261 cal/degxmol and 0.0122cal/degxmol for crude oil and antioxidant-treated crude oil, respectively and 0.0690 cal/degxmol and 0.0177 cal/degxmol for the refined oil. This study indicates T. catappa seed oil to be potential pharmaceutical oil with excellent characteristics.

    This study investigated the variations in the levels of phenolic compounds, vitamin C, sugars and antioxidant capacities of 45 newly collected accessions of Terminalia ferdinandiana (Kakadu plum), a native Australian fruit utilised in dietary supplement industry. Pattern recognition tools, principal component analysis (PCA) and agglomerative hierarchical clustering (AHC) were applied to understand interrelationships between the antioxidant capacities [Ferric reducing antioxidant power (FRAP) and Oxygen radical absorbance capacity (ORAC)] and antioxidant groups: phenolic compounds and vitamin C. On the basis of these parameters AHC classified samples into three main groups, with accessions 2, 8, 15, 6, 3 and 5 from the Northern Territory, Australia, representing superior quality fruits combining high levels of total phenolics (505.2 to 376.1 mg GA E/g DW), vitamin C (322.2 to 173.5mg/g DW), with pronounced antioxidant capacities (FRAP: 5030.5 to 4244.9 μmol Fe(2+)/g DW; ORAC: 3861.5 to 2985.6 μmol Trolox E/g DW). Hydrolysable tannins and ellagic acid were identified as the major phenolic compounds. The levels of ellagic acid varied from 140.2 to 30.5 mg/g DW, which places Kakadu plum as a unique edible source of this compound. The levels of sugars varied from 619.0 to 130.0 mg Glu E/g DW. This study for the first time revealed a unique phytochemical profile and significant variability in phytochemical composition of Kakadu plum. These features create opportunities for selection of sources with different characteristics addressing the needs of the nutraceutical industry, food processors and the consumers of fresh fruit.

    The environmentally friendly synthesis of nanoparticles process is a revolutionary step in the field of nanotechnology. In recent years plant mediated biological synthesis of nanoparticles has been gaining importance due to its simplicity and eco-friendliness. In this study, a simple and an efficient eco-friendly approach for the biosynthesis of stable, monodisperse silver nanoparticles using aqueous extracts of four Terminalia species, namely, Terminalia catappa, Terminalia mellueri, Terminalia bentazoe and Terminalia bellerica were described. The silver nanoparticles were characterized in terms of synthesis, capping functionalities (polysaccharides, phenolics and flavonoidal compounds) and microscopic evaluation by UV-visible spectroscopy, Fourier transform infrared spectroscopy and transmission electron microscopy. The results showed a simple and feasible approach for obtaining stable aqueous monodispersive silver nanoparticles. Furthermore, biological activity of the biosynthesized silver nanoparticles was examined. Concerning this, dose-dependent antioxidant activity of silver nanoparticles imparted by the plant phenolic and flavonoidal components was evaluated using in vitro 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay and found to be comparable to standard ascorbic acid. The same holds true for the anti-inflammatory activity where Terminalia catappa and Terminalia mellueri have a high-test inhibition percentage better than that of ascorbic acid in the carrageenan induced hind paw edema. The results also revealed that the aqueous extract of Terminallia catapa and its silver nanoparticles recorded the most potent in vivo antioxidant effect.

    Native Terminalia spp. in West Africa provide a popular source of construction timber as well as medical, spiritual and social benefits to rural populations. Very little is, however, known regarding the diseases that affect these trees. During an investigation into possible diseases of Terminalia spp. in Cameroon, orange to yellow fungal fruiting structures, resembling those of fungi in the Cryphonectriaceae, were commonly observed on the bark of native Terminalia ivorensis, and on dead branches of non-native Terminalia mantaly. In this study the fungus was identified based on morphological features as well as DNA sequence data (ITS and beta-tubulin) and its pathogenicity was tested on T. mantaly seedlings. Our results showed that isolates of this fungus represent a previously undescribed genus in the Cryphonectriaceae, which we describe as Aurifilum marmelostoma gen. et sp. nov. Pathogenicity tests revealed that A. marmelostoma is pathogenic on T. mantaly. These tests, and the association of A. marmelostoma with disease symptoms on T. ivorensis, suggest that the fungus is a pathogen of this important tree. PMID:20559872

    Terminalia species are a rich source of tannins. Many preparations of these species are used in traditional medicine and have many different ethnobotanical applications. A simple UHPLC method was developed for the simultaneous analysis of such hydrolysable tannins and triterpene saponins from the fruit rinds of different species of Terminalia (T. chebula, T. arjuna, T. bellirica) and Phyllantus emblica. A separation by LC was achieved using a reversed-phase column and a water/acetonitrile mobile phase, both containing formic acid, using a gradient system and a temperature of 40°C. Eight hydrolysable tannins (gallic acid, gallic acid methyl ester, corilagin, chebulagic acid, 1,2,3,6-tetra-O-galloyl-β-D-glucose, ellagic acid, chebulinic acid, and 1,2,3,4,6-penta-O-galloyl-β-D-glucose) and six triterpene saponins (arjunglucoside-I, arjunglucoside-III, chebuloside II, bellericoside, arjunetin, and arjunglucoside-II) could be separated within 20 minutes. The wavelength used for detection with the diode array detector was 254 and 275 nm for tannins and 205 nm for triterpene saponins. The method was validated for linearity, repeatability, limits of detection, and limits of quantification. The developed method is economical, fast, and especially suitable for quality control analysis of tannins and triterpene saponins in various plant samples and commercial products of Terminalia.

    The deciduous tree Terminalia bellirica found in Southeast Asia is extensively used in traditional Indian Ayurvedic medicine for the treatment of hypertension, rheumatism, and diabetes. The anti-atherogenic effect of Terminalia bellirica fruit has not been fully elucidated. Here, we investigated the effect of Terminalia bellirica extract (TBE) on low-density lipoprotein (LDL) oxidation and inflammation in macrophages. TBE showed 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity (EC50: 7.2 ± 1.2 μg/mL) and 15-lipoxygenase inhibitory activity. TBE also significantly inhibited free radical-induced LDL oxidation compared to the solvent control in vitro. In THP-1 macrophages, TBE treatment resulted in significant decreases of the mRNA expression of tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), and lectin-like oxidized LDL receptor-1 (LOX-1). TBE also reduced matrix metalloproteinase (MMP)-9 secretion and intracellular reactive oxygen species (ROS) production in THP-1 macrophages. These results show that TBE has the inhibitory effects on LDL oxidation and macrophage inflammatory response in vitro, suggesting that its in vivo use might inhibit atherosclerosis plaque progression.

    Premise of the study: Microsatellites were designed and characterized in the African timber forest tree Terminalia superba (Combretaceae). Due to their high variability, these markers are suitable to investigate gene flow patterns and the structure of genetic diversity. Methods and Results: From a genomic library obtained by next-generation sequencing, seven monomorphic and 14 polymorphic microsatellite loci were developed. The polymorphic microsatellites displayed two to 27 alleles (mean 11.4; expected heterozygosity range 0.283–0.940, mean 0.736) in one population from southeastern Cameroon. Genotypes were typical of an outbreeding diploid species, although null alleles explain a significant heterozygote deficit in three loci. Cross-amplification in three congeneric species (T. ivorensis, T. avicennioides, and T. mantaly) failed, suggesting that T. superba is rather divergent. Conclusions: This set of newly developed microsatellite markers will be useful for assessing the genetic diversity, population structure, and demographic history of T. superba in tropical African forests.

    2015-01-01

    Background: Plants of the family Combretaceae are amongst the most widely used plants for traditional medicinal purposes in southern Africa. In particular, many species of Combretum and Terminalia are used for their antibacterial, antifungal, antiprotozoal, antiviral, antidiarrhoeal, analgesic, antimalarial, antioxidant, anti-inflammatory and anticancer activities, yet their antimicrobial potential has not been rigorously studied and compared. Materials and Methods: A survey of antimicrobial activity was undertaken on selected South African Combretum and Terminalia species. Sixteen extracts from 6 Combretum and 2 Terminalia plant species with a history of medicinal usage were investigated by disc diffusion assay against a panel of bacteria and fungi and their MIC values were determined. Toxicity was determined using the Artemia franciscana nauplii bioassay. Results: All extracts tested displayed broad spectrum antibacterial activity, inhibiting the growth of 12-16 (75-100%) of the bacteria tested, with Gram-positive and Gram-negative bacteria being approximately equally susceptible. Potent antibacterial activities (generally in the range 200-5000 μg/ml) were evident for all Combretaceae extracts against both Gram-positive and Gram-negative bacteria. Similarly, the extracts also displayed good antifungal activity, inhibiting the growth of 2-3 (66.7-100%) of the fungal species tested, with fungal growth inhibition activities generally in the range 200–4000 μg/ml. In general, the Terminalia extracts had better efficacies than the Combretum extracts. Furthermore, the methanol extracts were generally better antimicrobial agents than the water extracts. All extracts were also shown to be non-toxic in the Artemia nauplii bioassay. Conclusion: The lack of toxicity of these extracts and their inhibitory bioactivity against a panel of bacteria and fungi indicate their potential as medicinal agents and partially validate their usage in multiple South African traditional

    Extracts from the leaves of the Bangladeshi medicinal plant Terminalia citrina were prepared, and 13 new furofuran lignan glucosides, terminalosides A-K (1-4, 6-12), 2-epiterminaloside D (5), and 6-epiterminaloside K (13), were characterized using various spectroscopic techniques. Twelve of the isolates were found to contain rare tetraoxygenated aryl groups in their structures. Analysis of the NMR chemical shifts for the oxymethine signals in the furofuran ring suggested a pragmatic approach to determining the relative configuration of these compounds. The ECD and NOESY spectroscopic data obtained allowed for the deduction of the absolute configurations and conformations of the compounds. The isolates were tested for their estrogenic/antiestrogenic activity using the MCF-7 and T47D estrogen-responsive human breast cancer cell lines. Terminalosides B (2) and G (8) exhibited inhibitory effects for both cell lines, and estradiol-enhanced cell proliferation was suppressed by 90% at concentrations lower than 10 μM. Terminaloside E (6) showed inhibitory activity against the T47D cell line, whereas terminalosides C (3), F (7), and I (10) and 6-epiterminaloside K (13) displayed antiestrogenic activity against MCF-7 cells.

    Visceral obesity induces the onset of metabolic disorders such as insulin resistance and diabetes mellitus. Adipose tissue is considered as a potential pharmacological target for treating metabolic disorders. The fruit of Terminalia bellirica is extensively used in Ayurvedic medicine to treat patients with diseases such as diabetes mellitus. We previously investigated the effects of a hot water extract of T. bellirica fruit (TB) on obesity and insulin resistance in spontaneously obese type 2 diabetic mice. To determine the active ingredients of TB and their molecular mechanisms, we focused on adipocyte differentiation using mouse 3T3-L1 cells, which are widely used to study adipocyte physiology. We show here that TB enhanced the differentiation of 3T3-L1 cells to mature adipocytes and that one of the active main components was identified as gallic acid. Gallic acid (10-30 µM) enhanced the expression and secretion of adiponectin via adipocyte differentiation and also that of fatty acid binding protein-4, which is the target of peroxisome proliferator-activated receptor gamma (PPARγ), although it does not alter the expression of the upstream genes PPARγ and CCAAT enhancer binding protein alpha. In the PPARγ ligand assay, the binding of gallic acid to PPARγ was undetectable. These findings indicate that gallic acid mediates the therapeutic effects of TB on metabolic disorders by regulating adipocyte differentiation. Therefore, TB shows promise as a candidate for preventing and treating patients with metabolic syndrome. PMID:27374289

    The present study was designed to evaluate in vitro anti-proliferative potential of extracts from four Indian medicinal plants, namely Anogeissus latifolia, Terminalia bellerica, Acacia catechu and Moringa oleiferna. Their cytotoxicity was tested in nine human cancer cell lines, including cancers of lung (A549), prostate (PC-3), breast (T47D and MCF-7), colon (HCT-16 and Colo-205) and leukemia (THP-1, HL-60 and K562) by using SRB and MTT assays. The findings showed that the selected plant extracts inhibited the cell proliferation of nine human cancer cell lines in a concentration dependent manner. The extracts inhibited cell viability of leukemia HL-60 and K562 cells by blocking G0/G1 phase of the cell cycle. Interestingly, A. catechu extract at 100 μg/mL induced G2/M arrest in K562 cells. DNA fragmentation analysis displayed the appearance of a smear pattern of cell necrosis upon agarose gel electrophoresis after incubation of HL-60 cells with these extracts for 24 h.

    The acute toxicity, the antioxidant activity, and the pharmacological activity on the gastrointestinal tract of rodents of the ethanolic extract (TFEE) from the bark of Terminalia fagifolia Mart. & Zucc. (Combretaceae) and of its aqueous (TFAqF), hydroalcoholic (TFHAF), and hexanic (TFHEXF) partition fractions have been evaluated. TFEE presented low acute toxicity, antioxidant, and antiulcerogenic activity against ethanol-induced ulcers, which was partially blocked by pretreatment with L-NAME and indomethacin. It reduced the total acidity and raised the pH of gastric secretion. Additionally, TFEE delayed gastric emptying and slightly inhibited the small intestinal transit and also presented a weakly antidiarrheal activity. The antiulcerogenic and antioxidant activity were also detected in TFAqF and TFHAF but not in TFHEXF. The antisecretory and gastroprotective activity of TFEE partially involve the nitric oxide and prostaglandin participation. Nevertheless, TFEE, TFAqF, and TFHAF drastically reduced the mucus layer adhered to the gastric wall of rats treated with ethanol or indomethacin. Complementary studies are required in order to clarify the paradox of the presence of a gastroprotector activity in this plant that, at the same time, reduces the mucus layer adhered to the gastric wall.

    The present study was designed to evaluate in vitro anti-proliferative potential of extracts from four Indian medicinal plants, namely Anogeissus latifolia, Terminalia bellerica, Acacia catechu and Moringa oleiferna. Their cytotoxicity was tested in nine human cancer cell lines, including cancers of lung (A549), prostate (PC-3), breast (T47D and MCF-7), colon (HCT-16 and Colo-205) and leukemia (THP-1, HL-60 and K562) by using SRB and MTT assays. The findings showed that the selected plant extracts inhibited the cell proliferation of nine human cancer cell lines in a concentration dependent manner. The extracts inhibited cell viability of leukemia HL-60 and K562 cells by blocking G0/G1 phase of the cell cycle. Interestingly, A. catechu extract at 100 μg/mL induced G2/M arrest in K562 cells. DNA fragmentation analysis displayed the appearance of a smear pattern of cell necrosis upon agarose gel electrophoresis after incubation of HL-60 cells with these extracts for 24 h. PMID:26434854

    Objectives. To investigate the anti-inflammatory effect of Coptis chinensis plus myrobalan (CM) in vitro and in vivo. Methods. The inflammation in mouse peritoneal macrophages was induced by lipopolysaccharide (LPS). Animal models were established by using ear swelling and paw edema of mouse induced by xylene and formaldehyde, respectively. In vitro, cytotoxicity, the phagocytosis of macrophages, the levels of nitric oxide (NO), induced nitric oxide synthase (iNOS), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) in cell supernatant were detected. In vivo, swelling rate and edema inhibitory rate of ear and paw were observed using CM-treated mice. Results. At 150–18.75 μg·mL−1, CM had no cytotoxicity and could significantly promote the growth and the phagocytosis of macrophages and inhibit the overproduction of NO, iNOS, TNF-α, and IL-6 in macrophages induced by LPS. In vivo, pretreatment with CM, the ear swelling, and paw edema of mice could be significantly inhibited in a dose-dependent manner, and the antiedema effect of CM at high dose was better than dexamethasone. Conclusion. Our results demonstrated that Coptis chinensis and myrobalan possessed synergistically anti-inflammatory activities in vitro and in vivo, which indicated that CM had therapeutic potential for the prevention and treatment of inflammation-mediated diseases.

    Atherosclerosis which results from gradual deposition of lipids in medium and large arteries is a leading cause of mortality worldwide. Terminalia arjuna is a herb of Combretaceae family which contains hypolipidemic compounds and flavonoids with high antioxidative properties. This study was conducted to determine the effect of ethanolic fraction of T. arjuna on blood lipids and atherosclerosis in rabbits fed with high fat diet (HFD). Twenty New Zealand rabbits of either sex were randomly divided into five groups: the first two were normal diet group and HFD (21% fat) group and the remaining three groups received high cholesterol diet supplemented with standard drug (Atorvastatin 10 mg kg−1 body weight), T. arjuna ethanolic fraction (100 and 200 mg kg−1 body weight), respectively. The concentration of total cholesterol (TC), low density lipoprotein (LDL) cholesterol, triglycerides (TGs), very low density lipoprotein (VLDL) cholesterol and high density lipoprotein (HDL) cholesterol was determined in rabbits at the start of the experiment, at the 14th, 30th days and at the end of the study. Anti-atherogenic index was calculated from the lipid profile of the rabbits before sacrifice. At the end of the experimental period, the aorta was removed for assessment of atherosclerotic plaques. Results show that T. arjuna significantly decreases TC, LDL and TG levels and increases HDL and lessens atherosclerotic lesion in aorta (P < .05). Hence T. arjuna extract can effectively prevent the progress of atherosclerosis. This is likely due to the effect of T. arjuna on serum lipoproteins and its antioxidant and anti-inflammatory properties. PMID:21785628

    Terminalia ivorensis, a tree of central African origin, is planted in several tropical countries for timber and veneer production. During the course of a recent disease survey, an unknown fungus was found associated with basal cankers on dying T. ivorensis in Ecuador. The fungus has orange fruiting structures and septate, fusoid ascospores, similar to those of Cryphonectria, a well-known genus of canker pathogens. The aim of this study was to identify the fungus and to assess its pathogenicity. Identification was based on morphological characteristics as well as DNA sequence data. DNA sequence data from the ITS regions of the rDNA operon and two regions of the beta-tubulin gene, were compared with published sequences of Cryphonectria species and the closely related genera Endothia and Chrysoporthe. Pathogenicity tests were conducted on T. superba saplings. Morphological characterisations revealed that the conidiomata of the fungus from T. ivorensis, differed from those typical of Cryphonectria in being superficial and rostrate. Only Cryphonectria longirostris was similar to the fungus from T. ivorensis, but could be distinguished from it based on conidial size. Phylogenetic analyses showed that the fungus from T. ivorensis grouped closely with species of Cryphonectria, Chrysoporthe and Endothia, yet formed a distinct clade. Pathogenicity tests on T. superba provided evidence that the fungus is able to cause distinct stem cankers. We conclude that the pathogenic fungus from T. ivorensis represents a new genus and new species in the Diaporthales and we provide the name Rostraureum tropicale for it. The genus is typified by R. tropicale. Furthermore, C. longirostris is transferred to Rostraureum. PMID:16209308

    Kidney stone formation during hyperoxaluric condition is inherently dependent on the interaction between renal epithelial cells and calcium oxalate (CaOx) crystals. Although modern medicine has progressed in terms of removal of these stones, recurrence and persistent side effects restricts their use. Strategies involving plant based agents which could be used as adjunct therapy is an area which needs to be explored. Plant proteins having antilithiatic activity is a hitherto unexplored area and therefore, we conducted a detailed identification and characterization of antilithiatic proteins from Terminalia arjuna (T. arjuna). Proteins were isolated from the dried bark of T. arjuna and those having molecular weights > 3 kDa were subjected to anion exchange chromatography followed by gel filtration chromatography. Four proteins were identified exhibiting inhibitory activity against CaOx crystallization and crystal growth kinetics The cytoprotective and anti-apoptotic efficacy of these purified proteins was further investigated on oxalate injured renal epithelial cells (MDCK and NRK-52E) wherein, injury due to oxalate was significantly attenuated and led to a dose dependent increase in viability of these cells. These proteins also prevented the interaction of the CaOx crystals to the cell surface and reduced the number of apoptotic cells. Identification of these 4 anionic proteins from the bark of T. arjuna was carried out by Matrix-assisted laser desorption/ionization-time of flight Mass spectrometry (MALDI-TOF MS). This was followed by database search with the MASCOT server and sequence similarity was found with Nuclear pore anchor, DEAD Box ATP-dependent RNA helicase 45, Lon protease homolog 1 and Heat shock protein 90-3. These novel proteins isolated from T. arjuna have the potential to inhibit CaOx crystallization and promote cell survival and therefore, offer novel avenues which need to be explored further for the medical management of urolithiasis.

    Background and Aims Density is a crucial variable in forest and wood science and is evaluated by a multitude of methods. Direct gravimetric methods are mostly destructive and time-consuming. Therefore, faster and semi- to non-destructive indirect methods have been developed. Methods Profiles of wood density variations with a resolution of approx. 50 µm were derived from one-dimensional resistance drillings, two-dimensional neutron scans, and three-dimensional neutron and X-ray scans. All methods were applied on Terminalia superba Engl. & Diels, an African pioneer species which sometimes exhibits a brown heart (limba noir). Key Results The use of X-ray tomography combined with a reference material permitted direct estimates of wood density. These X-ray-derived densities overestimated gravimetrically determined densities non-significantly and showed high correlation (linear regression, R2 = 0·995). When comparing X-ray densities with the attenuation coefficients of neutron scans and the amplitude of drilling resistance, a significant linear relation was found with the neutron attenuation coefficient (R2 = 0·986) yet a weak relation with drilling resistance (R2 = 0·243). When density patterns are compared, all three methods are capable of revealing the same trends. Differences are mainly due to the orientation of tree rings and the different characteristics of the indirect methods. Conclusions High-resolution X-ray computed tomography is a promising technique for research on wood cores and will be explored further on other temperate and tropical species. Further study on limba noir is necessary to reveal the causes of density variations and to determine how resistance drillings can be further refined. PMID:21131386

    Objective: The present study was undertaken to evaluate the antitumor and antioxidant status of ethanol extract of Terminalia catappa leaves against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. Materials and Methods: The leaves powder was extracted with Soxhlet apparatus and subjected to hot continuous percolation using ethanol (95% v/v). Tumor bearing animals was treated with 50 and 200 mg/kg of ethanol extract. EAC induced in mice by intraperitoneal injection of EAC cells 1 × 106 cells/mice. The study was assed using life span of EAC-bearing hosts, hematological parameters, volume of solid tumor mass and status of antioxidant enzymes such as lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) activities. Total phenolics and flavonoids contents from the leaves extract were also determined. Results: Total phenolics and flavonoids contents from the leaves extract were found 354.02 and 51.67 mg/g extract. Oral administration of ethanol extract of T. catappa (50 and 200 mg/kg) increased the life span (27.82% and 60.59%), increased peritoneal cell count (8.85 ± 0.20 and 10.37 ± 0.26) and significantly decreased solid tumor mass (1.16 ± 0.14 cm2) at 200 mg/kg as compared with EAC-tumor bearing mice (P < 0.01). Hematological profile including red blood cell count, white blood cell count, hemoglobin (11.91 ± 0.47 % g) and protein estimation were found to be nearly normal levels in extract-treated mice compared with tumor bearing control mice. Treatment with T. catappa significantly decreased levels of LPO and GSH, and increased levels of SOD and CAT activity (P < 0.01). Conclusion: T. catappa exhibited antitumor effect by modulating LPO and augmenting antioxidant defense systems in EAC bearing mice. The phenolic and flavonoid components in this extract may be responsible for antitumor activity. PMID:24130380

    Five new polyalkoxylated furofuranone lignan glucosides, terminalosides L-P (1-5), were isolated from EtOAc extracts of the leaves of Terminalia citrina, a Bangladeshi medicinal plant. The structures of the isolates were deduced primarily by NMR spectroscopy, and four of the isolates were found to contain rare tetraoxygenated aryl groups in their structures. The absolute configurations and conformations of the furofuranone ring were confirmed by ECD spectroscopy. All of the isolates were evaluated for their estrogenic and/or antiestrogenic properties using two estrogen responsive breast cancer cell lines, T47D and MCF-7. At a concentration of 10nM, terminaloside L (1) suppressed E2-enhanced T47D cell proliferation by 90%, while terminaloside M (2) showed 90% antiestrogenic activity against MCF-7 cells. Compared to 2, the antiestrogenic activity of terminaloside O (4) and P (5) was weak, possibly due to the different attachment positions of the sugar moiety that they share in common. This is the first report of furofuranone lignans from any Terminalia species, and also of their antiestrogenic activity. PMID:27425446

    Objectives: Folkloric claims on the use of a mixture of Anogeissus leiocarpus and Terminalia avicennioides root barks in tumor management exist without scientific evidence. This study aimed at investigating the phytochemical constituents and in vitro antiproliferative activity of these plants and their mixture. Materials and Methods: Phytochemical screening was carried out on the aqueous extracts after which various concentrations (0 to 1 000 μg/ml) were incubated with Ehrlich ascites carcinoma cell lines for 3 and 24 hours. Results: The extracts contained alkaloids, tannins, flavonoids, phenolics, saponins, phlobatannins, and terpenes. The separate extracts and their 1:1 mixture significantly (P<0.05) decreased the computed percentage viability of the cell lines in a dose- and time-dependent manner. Conclusions: The antiproliferative activity may be due to the presence of the bioactive compounds in the extracts and has a potential in the management of tumor. PMID:24014915

    Hyperlipidemia contributes significantly in the manifestation and development of atherosclerosis and coronary heart disease (CHD). Although synthetic lipid-lowering drugs are useful in treating hyperlipidemia, there are number of adverse effects. So the current interest has stimulated the search for new lipid-lowering agents with minimal side effects from natural sources. The present study was designed to investigate the antihyperlipidemic and antiatherogenic potentiality of ethanolic extract of Terminalia pallida fruits in high fat diet-induced hyperlipidemic rats. T. pallida fruits ethanolic extract (TPEt) was prepared using Soxhlet apparatus. Sprague-Dawley male rats were made hyperlipidemic by giving high fat diet, supplied by NIN (National Institute of Nutrition), Hyderabad, India. TPEt was administered in a dose of 100 mg/kg.b.w./day for 30 days in high fat diet-induced hyperlipidemic rats. The body weights, plasma lipid, and lipoprotein levels were measured before and after the treatment. TPEt showed significant antihyperlipidemic and antiatherogenic activities as evidenced by significant decrease in plasma total cholesterol, triglycerides, low-density lipoprotein cholesterol, and very low-density lipoprotein cholesterol levels coupled together with elevation of high-density lipoprotein cholesterol levels and diminution of atherogenic index in high fat diet-induced hyperlipidemic rats. There was a significantly reduced body weight gain in TPEt-treated hyperlipidemic rats than in the control group. The present study demonstrates that TPEt possesses significant antihyperlipidemic and antiatherogenic properties, thus suggesting its beneficial effect in the treatment of cardiovascular diseases.

    Visceral obesity induces insulin resistance and is recognized as an important risk factor for metabolic syndrome (MS). Therefore, inhibition of lipid absorption from the intestine is regarded as an effective way of preventing MS. Terminalia bellirica is extensively used in Ayurvedic medicine in India and neighboring countries, and the fruit of this plant has been reported to have hypoglycemic and hypolipidemic effects. In this study, we investigated the preventive effect of a hot water extract of T. bellirica fruit (TB) on obesity and various metabolic disorders, and explored its molecular mechanisms and active ingredients. TB treatment had a preventive effect on obesity, insulin resistance, and hyperlipidemia in spontaneously obese type 2 diabetic TSOD mice. To clarify the molecular mechanisms of TB in preventing obesity, we investigated the inhibitory effect on lipid absorption. TB suppressed absorption of triacylglycerol in an olive oil loading test (in vivo) and showed a strong inhibitory effect on pancreatic lipase activity (in vitro). Furthermore, a search for the active ingredients in TB revealed that gallic acid is the component primarily responsible for the inhibition of pancreatic lipase activity. Thus, our findings indicate that TB could be useful in preventing MS. The mechanisms probably involve suppression of the absorption of meal-derived lipids mediated by gallic acid. PMID:22105160

    Knowledge of ecological impacts of exotic beach almond (Terminalia catappa) in the central Pacific of Costa Rica are little known, but studies have found this species to be a potentially important food source for endangered scarlet macaws (Ara macao). In this study, reproductive phenology and seed predation by variegated squirrels (Sciurus variegatoides) and scarlet macaws were measured during March and April 2011 on beaches of central Pacific coastal Costa Rica. Seed productivity and predation levels were quantified on a weekly basis for 111 beach almond trees to assess the importance of beach almond as a food source for scarlet macaws and the extent of resource partitioning between seed predators. Seed production of the trees was great (about 194 272 seeds) and approximately 67% of seeds were predated by seed predators. Macaws consumed an estimated 49% of seeds while squirrels consumed 18%. Additionally, evidence of resource partitioning between squirrels and macaws was found. Scarlet macaws preferred to feed on the northern side and edge of the canopy while squirrels preferred to feed on the southern and inside parts of the canopy. Both species ate most seeds on the ocean side of the tree. Despite the status of this tree as an exotic species, the beach almond appears to be an important resource for scarlet macaw population recovery. The resource produced by this tree should be taken into account as reforestation efforts continue in Costa Rica. PMID:25412525

    Objective To ensure the safety and evaluate the anti oxidant activity of Terminalia paniculata (T. paniculata) ethanolic extract in Sprague Dawley rats. Methods The solvent extracts (hexane, ethyl acetate and ethanol) of T. paniculata were subjected to phytochemical analysis and their DPPH radical scavenging activity was assayed. The oral acute toxicity was evaluated using ethanolic extract of T. paniculata. Results Ethyl acetate and ethanolic extracts showed more phytochemicals, whereas highest DPPH scavenging activity was found in ethanolic extract. In an acute toxicity study, T. paniculata ethanolic extract was orally administered (1 000 mg/kg body weight) to rats and observed for 72 h for any toxic symptoms and the dose was continued up to 14 d. On the 15th day rats were sacrificed and blood samples were collected from control and test animals and analyzed for some biochemical parameters. We did not observe any behavioral changes in test groups in comparison with their controls. Also, there were no significant alterations in biochemical, hematological (hemoglobin content and blood cells count) and liver function parameters such as serum glutamate pyruvate transaminase, serum glutamate oxaloacetate transaminase, alkaline phosphatase, total proteins, albumin and bilirubin levels between T. paniculata ethanolic extract treated and normal control groups. Conclusions Together our results demonstrated that T. paniculata ethanolic possessed potent antioxidant activity and it was safer and non toxic to rats even at higher doses and therefore could be well considered for further investigation for its medicinal and therapeutic efficacy.

    Presently, no effective anthelmintic drugs have been used to treat and control paramphistomosis, a severe disease of ruminants. In this study, we have investigated the in vitro anthelmintic effect of the leaves of Terminalia catappa L. crude extract (TcCE) and albendazole (ABZ) on adult Fischoederius cobboldi after incubating the flukes in RPMI-1640 medium containing the TcCE at various doses and times. The TcCE-treated flukes at all dosages exhibited rapid decrease of motility, and the relative motility (RM) values were decreased sharply from start to 3 h. Worms were killed after 6 and 12 h of treatment with 1000, 1500 and 2000 µg mL(-1) as well as 500 µg mL(-1) of TcCE, respectively. By light microscopy examination, the flukes exhibited the earliest alteration in a limited area of the tegument. At scanning electron microscopy level, the flukes' tegument showed similar sequence of morphological alterations after treatment with ABZ and TcCE that consisted of swelling of ridges and folds, followed by blebbing and rupturing of the blebs, leading to the erosion, lesion and disruption of the tegument. Hence, in vivo studies should be performed to examine whether the TcCE may serve as a powerful anthelmintic drug for treatment of paramphistomosis. PMID:26831432

    Resource availability, degree of herbivore damage, genetic variability, and their interactions influence the allocation of investment by plants to resistance and tolerance traits. We evaluated the independent and interactive effects of soil nutrients and moisture, and simulated the effects of herbivore damage on condensed tannins (resistance) and growth/regrowth (tolerance) traits of Terminalia sericea, a deciduous tree in the Kalahari desert that constitutes a major component of livestock diet. We used a completely crossed randomized-block design experiment to examine the effects of nutrients, water availability, and herbivore damage on regrowth and resistance traits of T. sericea seedlings. Plant height, number of branches, internode length, leaf area, leaf mass for each seedling, combined weight of stems and twigs, and root mass were recorded. Condensed tannin concentrations were 22.5 and 21.5% higher under low nutrients and low soil moisture than under high nutrient and high water treatment levels. Tannin concentrations did not differ significantly between control and experimental seedlings 2 mo after simulated herbivore damage. Tannin concentrations correlated more strongly with growth traits under low- than under high-nutrient conditions. No trade-offs were detected among individual growth traits, nor between growth traits and condensed tannins. T. sericea appeared to invest more in both resistance and regrowth traits when grown under low-nutrient conditions. Investment in the resistance trait (condensed tannin) under high-nutrient conditions was minimal and, to a lesser degree, correlated with plant growth. These results suggest that T. sericea displays both resistance and tolerance strategies, and that the degree to which each is expressed is resource-dependent.

    Worldwide, Ischemic heart disease (IHD) affects a large population. Implication of myocardial infarction (MI) and its multiple pathophysiology in cardiac function is well known. Further, isoproterenol (ISP) is known to induce MI. Today, there is an urgent need for effective drug that could limit the myocardial injury. Therapeutic intervention with antioxidants has been shown useful in preventing the deleterious changes produced by ISP. Here, we investigated the protective effects of oral pre-treatment of hydroalcoholic extract of bark of Terminalia arjuna (HETA) on biochemical and apoptotic changes during cardiotoxicity induced by isoproterenol (ISP) in rats. HETA was orally administered at a dose of 100, 200 and 400 mg/kg body wt., for 30 days with concurrent administration of ISP (85 mg/kg body wt.) on days 28th and 29th at an interval of 24 h. ISP caused deleterious changes in the myocardium and significantly increased (P < 0.05) malondialdehyde, serum glutamate oxaloacitate transaminase, creatine kinase-MB, lactate dehydrogenase and troponin-I. However, it significantly decreased (P < 0.05) glutathione and superoxide dismutase compared to healthy control. Oral pre-treatment of HETA for 30 days significantly decreased (P < 0.05) the biochemical parameters of oxidative stress and cardiac markers as compared to ISP control. Histopathological findings also revealed that architecture of the myocardium was restored towards normal in HETA pre-treated group. Overall, the present study has shown that the hydroalcoholic extract of bark of T. arjuna (HETA) attenuates oxidative stress, apoptosis and improves antioxidant status in ISP-induced cardiotoxicity in rats.

    The study examined the effect of various processing methods- boiling, drying and roasting- on the in vitro and in vivo protein digestibility and free amino acid profiles of Terminalia catappa seed. Moisture and crude protein of the various samples were determined. In vitro protein digestibility was determined after pepsin digestion. For the in vivo experiment, defatted T. catappa based diet was fed to 3 weeks old Wistar rats for 4 weeks and compared with animals maintained on casein based and nitrogen- free diets. The biological value (BV), net protein utilisation (NPU) and protein efficiency ratio (PER) of the diets were determined. Free amino acid composition was carried out using thin layer chromatography. Moisture was highest in the boiled T. catappa seed (8.30 ± 0.00 %). The raw, roasted and dried seeds had 5.55 ± 0.07, 3.88 ± 0.22 and 3.75 ± 0.07 % respectively. Crude protein was 19.19, 18.89, 17.62 and 16.36 % in the dried, roasted, boiled and raw seeds respectively. Roasted T. catappa seed had the highest in vitro protein digestibility with 37.52 %, while the dried, boiled and raw samples had digestibility values of 27.57, 27.07 and 24.45 % respectively. All nine essential amino acids were present in T. catappa in high concentrations except methionine and tryptophan. Glutamate was present in the highest concentration. Also, free amino acids were higher in the processed seeds compared to the raw seed. Animals fed T. catappa diet compared favourably with the casein group, thus indicating that the protein is of good quality.

    The structure and musculature of the male terminalia are described and illustrated in 11 genera of the tribe Cidariini (Lepidoptera, Geometridae, Larentiinae) from the Holarctic and Oriental regions. Nine genital muscles were identified: m1, m2(10), m3(2), m4, m5(7), m6(5), m7(6), m8(3) and m21. Variation in the insertion of the muscles m1, m3(2), m4, m5(7), m6(5) and m8(3) on the sclerites in several generic groups of the tribe Cidariini is discussed, revealing that the Thera species group does not share some apparently cidariine characters. A comparative analysis of the musculature in the tribes Cidariini and Xanthorhoini questions the sister relationship of these tribes that was suggested by earlier studies. The application of the terms 'anellus lobes' and 'labides' is discussed.

    The musculature of the male genitalia was reviewed for the tribe Xanthorhoini and related tribes (Lepidoptera, Geometridae, Larentiinae). The genitalia morphology of males of 11 species was discussed and illustrated, and nine paired and unpaired genital muscles identified. Muscles m1, m2(10), m5(7), m6(5), m7(6), m8(3) and m21 have similar position in all species considered in the paper. Comparative morphology of the male terminalia and position of extensors of the valvae m3(2) and flexors m4 confirmed the previously uncertain separation of Euphyiini and Scotopterygini. Cataclysmini share musculature characters with the tribe Xanthorhoini. The generic affiliation of Xanthorhoe biriviata (Borkhausen) is questionable considering an unusual location of muscles m4. Generally, the places of attachment of the muscles m3(2) and m4 to the sclerites afford valuable characters for the higher classification of this group.

    Gums are used as binders in tablets and also as emulsion stabilisers, suspending agents and thickeners in syrups. The need for other natural gums apart from the conventional gums to be employed as binding agents in tablets formulation led to this study. A gum obtained from the incised trunk of Terminalia randii (Combretaceae) was evaluated for the effect of compression pressure, methyl paraben preservative and storage with potassium chloride, on the microbial load of tablets formulated with the gum. The microbial load was determined by surface spread method on the processed gum at suitable dilutions, and tablets formulated from the gum at different compression pressures. The formulated tablets were evaluated for microbial load, also when stored in potassium chloride for 8 and 12 weeks with and without preservation with 1% Methyl Paraben. In each case the compressed tablets were incubated in 0.1% peptone water as control. The microbial load recorded reflected generally, reduction in microbial counts in tablets formulated with the gum as a binder both in terms of compression at different pressures and when the different compression pressures were associated with or without 1% methyl paraben in the presence of potassium chloride. Comparatively, the processed gum showed higher microbial load than the pressure compressed tablets. Besides the different compression pressures, duration of storage was also found to cause reduction of microbial load, particularly in the formulated tablets compressed with methyl paraben stored in potassium chloride such that after 8 weeks, the microbial load was zero. The studies showed that compression pressures and duration of storage caused marked reduction in microbial load of the tablets formulated with the processed gum of Terminalia randii as a binder.

    Indian almond (Terminalia catappa Linn.) leaves with green and red coloration were tested for bactericidal activity with pathogenic bacteria and their acute toxicity to Siamese fighting fish (Betta splendens Regan). Powder of Indian almond leaves was extracted with water at the ratio of 1:10 (w/v) and then freeze-dried to a dry powder. Bactericidal efficacy was tested against 28 isolates of pathogenic bacteria (Aeromonas hydrophila, Edwardsiella tarda, Enterobacter spp., Plesiomonas shigelloides, Pseudomonas spp., Shewanella putrefaciens, Staphylococcus sp. and Streptococcus sp.) isolated from Siamese fighting fish. A paper disc diffusion method was tested on Mueller Hinton Agar (MHA) by inoculating 1 x 106 CFU/mL of each bacterial suspension. Paper disks (5 mm) were impregnated with either 10 microl of green or red Indian almond leaf extract at a concentration of 12,000 ppm, then laid on the surface of the MHA. The results revealed that aqueous extract of red Indian almond leaves could inhibit the growth of tested bacteria better than the green extract. The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) were determined. Extracts of green and red leaves were diluted in Mueller Hinton Broth (MHB) to obtain a starting extract concentration of 6,000 ppm then twofold serially diluted in a 96-well microtitre plate. The pathogenic bacteria were inoculated into each well at a density of 1 x 105 CFU/mL and incubated at 35 degrees C for 24 h. The growth of bacteria was detected by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazoliium bromide. The MIC of the red leaf extract ranged from 187.5 to 375 ppm which was lower than for green leaf extract (375-750 ppm). The MBC range of the red leaf extract was 375-750 ppm which was lower than for the green leaf extract (750-1,500 ppm).

Roxb. In the first step, six kinds of resins were investigated by adsorption and desorption tests and AB-8 macroporous resin was selected for the enrichment of gallic acid. As a result, 20 g of gallic acid at a purity of 71% could be separated from 100 g of crude extract in which the content of gallic acid was 16.7% and the recovery of gallic acid reached 85.0%. In the second step, preparative high-performance liquid chromatography was selected to purify gallic acid. As a result, 640 mg of gallic acid at a purity of 99.1% was obtained from 1 g of sample in 35 min. The results demonstrated that macroporous resin coupled with preparative high-performance liquid chromatography was suitable for preparation of gallic acid from T. bellirica (Gaertn.) Roxb.

    The use of natural reagents from plant extracts for chemical analysis is one of the approaches in the development of low cost and environmentally friendly green analytical chemistry methodology. Here, crude extract from Indian Almond (Terminalia Catappa L.) leaves was used for colorimetric determination of aluminum by monitoring the absorbance of the Al(3+)-extract complex at 435 nm. Dry leaves and freeze-dried fresh leaf extract can be kept for extended use. A simple flow injection analysis (FIA) system was also employed for rapid analysis (approximately 180 injections/h). The linear working range up to 100 mg L(-1) was established with a detection limit (blank + 3SD) of 0.8 mg L(-1), a limit of quantitation (blank + 10SD) of 2.4 mg L(-1), and a relative standard deviation of 3-5%. This simple green analytical chemistry methodology was applied for the determination of Al(3+) in waste water samples from ceramic factories. The results agreed well with the results obtained from the ICP-OES technique. PMID:23749133

    Terminalia is a genus of Combretaceous plants widely distributed in tropical and subtropical regions. Thus, the aim of this study was to quantify the majority compounds of the hydroalcoholic extract (7 : 3, v/v) of the leaves from T. catappa by HPLC-PDA, chemically characterize by hyphenated techniques (HPLC-ESI-IT-MSn) and NMR, and evaluate its mutagenic activity by the Salmonella/microsome assay on S. typhimurium strains TA98, TA97a, TA100, and TA102. The quantification of analytes was performed using an external calibration standard. Punicalagin is the most abundant polyphenol found in the leaves. The presence of this compound as a mixture of anomers was confirmed using HPLC-PDA and 1H and 13C NMR. Mutagenic activity was observed in strains TA100 and TA97a. As the extract is a complex mixture of punicalagin, its derivatives, and several other compounds, the observed mutagenicity may be explained in part by possible synergistic interaction between the compounds present in the extract. These studies show that mutagenic activity of T. catappa in the Ames test can only be observed when measured at high concentrations. However, considering the mutagenic effects observed for T. catappa, this plant should be used cautiously for medicinal purposes. PMID:24734110

    2014-01-01

    Background This study was performed to understand the possible therapeutic activity of Terminalia paniculata ethanolic extract (TPEE) on non alcoholic fatty liver in rats fed with high fat diet. Methods Thirty six SD rats were divided into 6 groups (n = 6): Normal control (NC), high fat diet (HFD), remaining four groups were fed on HFD along with different doses of TPEE (100,150 and 200 mg/kg b.wt) or orlistat, for ten weeks. Liver tissue was homogenized and analyzed for lipid profiles, activities of superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) content. Further, the expression levels of FAS and AMPK-1α were also studied in addition to histopathology examination of liver tissue in all the groups. Results HFD significantly increased hepatic liver total cholesterol (TC), triglycerides (TG), free fatty acids (FFA) and MDA but decreased the activities of SOD and CAT which were subsequently reversed by supplementation with TPEE in a dose-dependent manner. In addition, TPEE administration significantly down regulated hepatic mRNA expression of FAS but up regulated AMPK-1α compared to HFD alone fed group. Furthermore, western blot analysis of FAS has clearly demonstrated decreased expression of FAS in HFD + TPEE (200 mg/kg b.wt) treated group when compared to HFD group at protein level. Conclusions Our biochemical studies on hepatic lipid profiles and antioxidant enzyme activities supported by histological and expression studies suggest a potential therapeutic role for TPEE in regulating obesity through FAS.

    The thirty known species of Oragua are distributed from southern Mexico to Argentina. Seventeen species are recorded from Brazil, but only O. elegantula Young, 1977, O. insipida Young, 1977, and O. jurua Young, 1977 are recorded from Amazonas State. Oragua partitula (Jacobi, 1905) is herein firstly recorded from Brazil, ocurring in Amazonas State. The aim of the study was to describe eight new species of Oragua, to provide a key to males of the species of the genus that are recorded from Amazonas State and to study in detail the female terminalia of these new species. Also, the female of O. jurua Young, 1977 is herein described for the first time. Oragua alerochae sp. nov. has the external color pattern similar to O. bifasciata Cavichioli, 2000, however, the head is darker, the forewings are paler and the stripes are thinner, aedeagus is much more curved with long apical processes, and apex of paraphyses rami are curved. Oragua aurantimaculata sp. nov. is similar externally to O. elegantula and Oragua jau sp. nov. as they share the body brown with three orange maculae on crown and orange maculae on forewings, but it has the aedeagus with shaft enlarged medially with a pair of apical processes curved anteriorly and connective more slender. Oragua bella sp. nov. is dark with orange spots, aedeagus with basal elongated processes extending to the apex of the pygofer, with the basal portion enlarged and narrowing toward the apex. Oragua copiosa sp. nov. is dark with small pale dots all over the body, paraphyses rami are slender and their apices expanded, and styles with hooked apex, extending posteriorly beyond the connective apex. Oragua gracilenta sp. nov. has the external color similar to O. galerula, but it can be distinguished by the brown ground color, absence of two maculae near median line just before posterior margin on pronotum and apex of rami of paraphyses bifurcate and not truncate. Oragua jau sp. nov. has the external color similar to O. elegantula, but

    Wild edible fruits contribute significantly to the nutritional security of mankind across the globe. However, detailed analyses of health promoting bioactive compounds and antioxidants are lacking, especially in Himalayan wild edible fruits. Bioactive compounds and antioxidant potential of 10 wild edible fruits reveal that Terminalia chebula, Phyllanthus emblica and Myrica esculenta are the richest source of total phenolics; Pyaracantha crenulata, Terminalia chebula and Berberis asiatica for flavonoids; Phyllanthus emblica, Morus alba and Ficus palmata for ascorbic acid, anthocyanins, and Morus alba for β-carotene. Phenolic compounds, i.e. Gallic acid, catechin, chlorogenic acid, caffeic acid and p-coumaric acid varied among species and found the maximum in Terminalia chebula and Phyllanthus emblica. Antioxidant activity showed the significant relation with total phenolics, flavonoids and phenolic compounds. Results indicated that these species should be promoted as a natural source of antioxidant/nutraceuticals so that these antioxidants can be used for supplementing dietary foods of mountain people.

    2006-01-01

    Background Carbon tetrachloride (CCl4) is a well-known hepatotoxin and exposure to this chemical is known to induce oxidative stress and causes liver injury by the formation of free radicals. Acute and chronic renal damage are also very common pathophysiologic disturbances caused by CCl4. The present study has been conducted to evaluate the protective role of the aqueous extract of the bark of Termnalia arjuna (TA), an important Indian medicinal plant widely used in the preparation of ayurvedic formulations, on CCl4 induced oxidative stress and resultant dysfunction in the livers and kidneys of mice. Methods Animals were pretreated with the aqueous extract of TA (50 mg/kg body weight) for one week and then challenged with CCl4 (1 ml/kg body weight) in liquid paraffin (1:1, v/v) for 2 days. Serum marker enzymes, namely, glutamate pyruvate transaminase (GPT) and alkaline phosphatase (ALP) were estimated in the sera of all study groups. Antioxidant status in both the liver and kidney tissues were estimated by determining the activities of the antioxidative enzymes, superoxide dismutase (SOD), catalase (CAT) and glutathione-S-transferase (GST); as well as by determining the levels of thiobarbutaric acid reactive substances (TBARS) and reduced glutathione (GSH). In addition, free radical scavenging activity of the extract was determined from its DPPH radical quenching ability. Results Results showed that CCl4 caused a marked rise in serum levels of GPT and ALP. TBARS level was also increased significantly whereas GSH, SOD, CAT and GST levels were decreased in the liver and kidney tissue homogenates of CCl4 treated mice. Aqueous extract of TA successfully prevented the alterations of these effects in the experimental animals. Data also showed that the extract possessed strong free radical scavenging activity comparable to that of vitamin C. Conclusion Our study demonstrated that the aqueous extract of the bark of TA could protect the liver and kidney tissues against CCl4-induced oxidative stress probably by increasing antioxidative defense activities.

    Herbal remedies have a long history of use for gum and tooth problems such as dental caries. The present microbiological study was carried out to evaluate the antimicrobial efficacy of three medicinal plants (Terminalia chebula Retz., Clitoria ternatea Linn., and Wedelia chinensis (Osbeck.) Merr.) on three pathogenic microorganisms in the oral cavity (Streptococcus mutans, Lactobacillus casei, and Staphylococcus aureus). Aqueous extract concentrations (5%, 10%, 25%, and 50%) were prepared from the fruits of Terminalia chebula, flowers of Clitoria ternatea, and leaves of Wedelia chinensis. The antimicrobial efficacy of the aqueous extract concentrations of each plant was tested using agar well diffusion method and the size of the inhibition zone was measured in millimeters. The results obtained showed that the diameter of zone of inhibition increased with increase in concentration of extract and the antimicrobial efficacy of the aqueous extracts of the three plants was observed in the increasing order - Wedelia chinensis < Clitoria ternatea < Terminalia chebula. It can be concluded that the tested extracts of all the three plants were effective against dental caries causing bacteria. PMID:23723653

    Ethanolic extracts and some fractions from 10 Indian medicinal plants, known for antibacterial activity, were investigated for their ability to inhibit clinical isolates of beta-lactamase producing methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive S. aureus (MSSA). Synergistic interaction of plant extracts with certain antibiotics was also evaluated. The MRSA test strains were found to be multi-drug resistant and also exhibited high level of resistance to common beta-lactam antibiotics. These strains produced beta-lactamases, which hydrolyze one or other beta-lactam antibiotics, tested. The extract of the plants from Camellia sinensis (leaves), Delonix regia (flowers), Holarrhena antidysenterica (bark), Lawsonia inermis (leaves), Punica granatum (rind), Terminalia chebula (fruits) and Terminalia belerica (fruits) showed a broad-spectrum of antibacterial activity with an inhibition zone size of 11 mm to 27 mm, against all the test bacteria. The extracts from the leaves of Ocimum sanctum showed better activity against the three MRSA strains. On the other hand, extracts from Allium sativum (bulb) and Citrus sinensis (rind) exhibited little or no activity, against MRSA strains. The antibacterial potency of crude extracts was determined in terms of minimum inhibitory concentration (MIC) by the tube dilution method. MIC values, of the plant extracts, ranged from 1.3 to 8.2 mg/ml, against the test bacteria. Further, the extracts from Punica granatum and Delonix regia were fractionated in benzene, acetone and methanol. Antibacterial activity was observed in acetone as well as in the methanol fractions. In vitro synergistic interaction of crude extracts from Camellia sinensis, Lawsonia inermis, Punica granatum, Terminalia chebula and Terminalia belerica was detected with tetracycline. Moreover, the extract from Camellia sinensis also showed synergism with ampicillin.TLC of the above extracts revealed the presence of major phytocompounds, like

  5. Thai ethnomedicinal plants as resistant modifying agents for combating Acinetobacter baumannii infections

    PubMed Central

    2012-01-01

    Abstracts Background Acinetobacter baumannii is well-recognized as an important nosocomial pathogen, however, due to their intrinsic resistance to several antibiotics, treatment options are limited. Synergistic effects between antibiotics and medicinal plants, particularly their active components, have intensively been studied as alternative approaches. Methods Fifty-one ethanol extracts obtained from 44 different selected medicinal plant species were tested for resistance modifying agents (RMAs) of novobiocin against A. baumannii using growth inhibition assay. Results At 250 μg/ml, Holarrhena antidysenterica, Punica granatum, Quisqualis indica, Terminalia bellirica, Terminalia chebula, and Terminalia sp. that possessed low intrinsic antibacterial activity significantly enhanced the activity of novobiocin at 1 μg/ml (1/8xminimum inhibitory concentration) against this pathogen. Holarrhena antidysenterica at 7.8 μg/ml demonstrated remarkable resistant modifying ability against A. baumannii in combination with novobiocin. The phytochemical study revealed that constituents of this medicinal plant contain alkaloids, condensed tannins, and triterpenoids. Conclusion The use of Holarrhena antidysenterica in combination with novobiocin provides an effective alternative treatment for multidrug resistant A. baumannii infections. PMID:22536985

    Background The herb formulation Deva-5 is used in traditional medicine to treat acute infectious diseases. Deva-5 is composed of five herbs: Gentiana decumbens L., Momordica cochinchinensis L., Hypecoum erectum L., Polygonum bistorta L., and Terminalia chebula Retz. Deva-5 and its five components were investigated for in vitro antiviral activity against avian influenza A virus subtype H3N8. Methods The water extracts of the herbal parts of G. decumbens, H. erectum and P. bistorta, the seeds of T. chebula and M. cochinchinensis and Deva-5 were prepared by boiling and clarified by low-speed centrifugation and filtration. To assess the antiviral properties, avian influenza virus isolate A/Teal/Tunka/7/2010(H3N8) was incubated at 37°C for 30 min in the presence and absence of the extracts of five plants and DEVA-5 in various concentrations. Subsequently, the concentration of infectious virus in each sample was determined by plaque assays. Neutralisation indexes and 90% plaque reduction concentrations were estimated for each extract, and the significance of the data was evaluated using statistical methods. Results The extracts of G. decumbens, H. erectum, P. bistorta and Deva-5 demonstrated no significant toxicity at concentrations up to 2%, whereas extracts of T. chebula and M. cochinchinensis were well-tolerated by Madin-Darby canine kidney cells at concentrations up to 1%. The extracts of H. erectum, M. cochinchinensis and T. chebula reduced the titre of A/Teal/Tunka/7/2010 (H3N8) by approximately five-fold (p ≤ 0.05). The other three extracts did not significantly reduce the infectivity of the virus. The plaque reduction neutralisation tests revealed that none of the extracts tested were able to inhibit formation of plaques by 90%. However, three extracts, H. erectum, T. chebula and M. cochinchinensis, were able to inhibit formation of plaques by more than 50% at low dilutions from 1:3 to 1:14. The T. chebula extract had a concentration-dependent inhibitory

    Dental caries is a widely prevalent infectious disease afflicting the humans worldwide. Each year oral infections such as dental caries, periodontal diseases and oral candidiasis significantly adds to the economic burden of the world. Though there are standard management techniques for these diseases; they do have side effects and are not cost effective. Ayurveda is a traditional Indian system of medicine that is being practiced in the Indian peninsula since ages. Among the various herbal medicines in ayurveda, triphala occupies a royal position due to its wide beneficial systemic actions. Triphala is a mixture of fruits of Terminalia bellirica, Terminalia chebula and Emblica officinalis. The antimicrobial actions of triphala are well documented in the literature. However availability of review articles regarding triphala as an antimicrobial against oral infections is limited. Need was felt to review this aspect of triphala. The present article reviews the use of triphala and its constituents in the prevention and control of dental caries and other common oral infections. Thorough review of the literature indicated that triphala can be effectively used to manage dental caries, gingival and periodontal diseases. Further it can also be utilized as a root canal irrigant and against oral candida species.

    The aqueous extract of Jwarhar mahakashay Ayurvedic preparation (from the roots of Hemidesmus indicus R. Br., Rubia cordifolia L., Cissampelos pareira L.; fruits of Terminalia chebula Retz., Emblica officinalis Gaertn., Terminalia bellirica Roxb., Vitis vinifera L., Grewia asiatica L., Salvadora persica L. and granules of Saccharum officinarum L.) has been used as a traditional antipyretic. Experimental studies confirmed its antipyretic–analgesic effect with very low ulcerogenicity and toxicity. Flavonoids, glycosides and tannins were later found to be present in the extract. Detailed chemical investigations were undertaken after hydrolysis of extract using spectroscopic and chromatography methods to determine its active chemical constituent. UV-Visible spectroscopy showed absorbance maxima at 220 and 276 nm, while fourier transform infra-red investigations indicated an end carboxylic O–H structure at 2940 cm−1 suggesting the presence of glycoside-linked flavonoids. Thin layer chromatography and high performance liquid chromatography also confirmed the possibility of at least one major and two minor compounds in this abstract. Detailed examination using gas chromatography-mass spectrometry led to the identification of the principal component as 2-(1-oxopropyl)-benzoic acid, which is quite similar to the active compound found in the standard drug Aspirin (2-acetyl-oxybenzoic acid).

    The role of plant extracts and Ayurvedic polyherbal preparations in treating various ailments has been acknowledged since time immemorial. Studies based on the effect of these extracts in treatment of different diseases have also been well documented. Indian medicinal literature also emphasizes the synergistic effect of polyherbal drugs in restoring and rejuvenating immune system. This review focuses on the immunomodulatory potential of the polyherbal preparation, Triphala and its three constituents, Terminalia bellerica, Terminalia chebula and Emblica officinalis. The role of Triphala and its extract has been emphasized in stimulating neutrophil function. Under stress condition such as noise, Triphala significantly prevents elevation of IL-4 levels as well as corrects decreased IL-2 and IFN-γ levels. Under the condition of inflammatory stress its immunosuppressive activity is attributed to its inhibitory action on complement system, humoral immunity, cell mediated immunity and mitogen-induced T-lymphocyte proliferation. The aqueous and alcoholic extracts of the individual constituents reportedly enhance especially the macrophage activation due to their free radical scavenging activity and the ability to neutralize reactive oxygen species. This study thus concludes the use of Triphala and its three individual constituents as potential immunostimulants and/or immunosuppressants further suggests them to be a better alternative for allopathic immunomodulators.

    The development of anthelmintic resistance has made the search for alternatives to control gastrointestinal nematodes of small ruminants imperative. Among these alternatives are several medicinal plants traditionally used as anthelmintics. This present work evaluated the efficacy of ethyl acetate, acetone, and methanol dried leaf and seed extracts of five medicinal plants were tested in vitro ovicidal and larvicidal activities on Haemonchus contortus. The in vitro assay was based on egg hatch assay (EHA) and larval development assay (LDA), all plant extracts were evaluated at five concentrations 50, 25, 12.5, 6.25 and 3.13 mg/ml. The leaf and seed ethyl acetate, acetone and methanol of Annona squamosa, Eclipta prostrata, Solanum torvum, Terminalia chebula, and Catharanthus roseus extracts were showed complete inhibition (100%) at the maximum concentration tested (50 mg/ml). The overall findings of the present study have shown that our experimental plant extracts contain possible anthelmintic compounds. PMID:20980034

    Penta-O-galloyl-β-D-glucose (PGG) occurrs in high concentrations in medicinal herbs such as Rhus chinensis, Paeonia suffruticosa, Acer truncatum and Terminalia chebula, which demonstrate anti-inflammatory activity. We investigated the effect of PGG on stimulated and non-stimulated neutrophils in processes which included reactive oxygen species generation (ROS), metalloproteinase-9 and interleukin-8 secretion (IL-8), β₂ integrin (CD11b) and L-selectin (CD62L) expression and apoptosis. In concentrations of 5 μM-20 μM, PGG demonstrated statistically significant inhibition of ROS generation, IL-8 secretion and β₂ integrin expression in stimulated neutrophils. The inhibition of L-selectin expression by PGG resulted in prevention in neutrophils' endothelial attachment. The result obtained may explain the anti-inflammatory activity of this compound and underline the contribution of PGG in the activity of PGG rich plant extracts.

    Context: Sodium hypochlorite is the most commonly used irrigant but it has disadvantage like high cytotoxicity. So there is a need to find an alternative to 5.25% Sodium hypochlorite against microorganism Enterococcus faecalis and Candida albicans. Literature has shown that these 5 extracts namely Terminalia chebula, Myristica frangrans, Aloe barbadensis, Curcuma longa and Azadaricta indica has good properties which can be used as a potential endodontic irrigant. Aims: To evaluate the antimicrobial efficacy of various herbal extracts namely Curcuma longa (CL), Azadiracta indica (AI), Aloe barbadensis (AV), Myristica fragrans (MF) and Terminalia chebula (TC) as endodontic irrigant against Enterococcus faecalis and Candida albicans using real-time quantitative polymerase chain reaction (qPCR). Materials and Methods: Eighty-four teeth were extracted and suspended with Enterococcus faecalis and Candida albicans. A preliminary study was first performed to determine the minimum inhibitory concentration of extracts. The irrigating groups were divided into five herbal groups and 2 control groups. After irrigating the teeth the remaining microbial load was determined using qPCR. Statistical Analysis Used: Statistical analysis was performed using Oneway Anova/Kruskal-Wallis test with post-hoc Tukey's HSD and was statistically significant (P < 0.05). Results: It was shown that Neem was highly efficient to 5.25% NaOCl in reducing Enterococcus faecalis and Candida albicans within the root canals when compared with other extracts. Conclusions: Neem leaf extract has a significant antimicrobial efficacy against Enterococcus faecalis and Candida albicans compared to 5.25% sodium hypochlorite. PMID:23716972

    Background: Nepal is very rich in biodiversity, and no extensive effort has yet been carried out to screen plants that are used by traditional healers against parasitic diseases. The aim of this study was to evaluate the in vitro antileishmanial and antimalarial activity of crude methanolic or ethanolic extracts of 29 plant species that are currently used by local people of Nepal for treating different ailments. Methods: Crude extracts of leaves, twigs, aerial parts, and/or roots of the selected plants were evaluated for in vitro inhibitory activity against intracellular amastigotes of Leishmania infantum and against erythrocytic stages of Plasmodium falciparum. To determine the selectivity index (SI), cytotoxicity was assessed on MRC-5 cells in parallel. Results: Three plant species, namely Phragmites vallatoria and Ampelocissus tomentosa, for which no antiprotozoal activity has previously been reported, and Terminalia chebula revealed antiprotozoal activity. The extract of A. tomentosa exhibited moderate activity against L. infantum with an inhibitory concentration 50% (IC50) of 13.2 ± 4.3 µg/ml and SI >3, while T. chebula exhibited fairly good antiplasmodial activity with IC50 values of 4.5 ± 2.4 µg/ml and SI values >5. Conclusion: In countries like Nepal, where the current health system is unable to combat the burden of endemic parasitic diseases, evaluation of local plants as a potential source of the drug can help in expanding the treatment options. The extent of untapped resources available in these countries provides an opportunity for future bioprospecting. PMID:27757268

Vent. were collected from different regions of Western Ghats and exposed to different doses of gamma radiation using Co-60 source. The effect of irradiation was examined on germination, growth and vigor parameters. Decrease in the germination and growth attributes with increased dose was observed in A. hirsutus, G. xanthochymus and S. asoca and thus indicating sensitivity of these plants to radiation. In contrast, enhancement in the germination (percentage), vigor and generation of leaves was observed for P. marsupium, T. chebula, H. integrifolia and O. indicum. These plants were classified as radiation tolerant because of the ability of their seedlings to successfully establish under radiation stress. R. minor and A. lindleyana were able to maintain viability up to 100 Gy dose, however, any further increase in the dose found to have negative effect. PMID:24631785

    The harvest of non-timber forest products (NTFPs), together with other sources of anthropogenic disturbance, impact plant populations greatly. Despite this, conservation research on NTFPs typically focuses on harvest alone, ignoring possible confounding effects of other anthropogenic and ecological factors. Disentangling anthropogenic disturbances is critical in regions such as India’s Western Ghats, a biodiversity hotspot with high human density. Identifying strategies that permit both use and conservation of resources is essential to preserving biodiversity while meeting local needs. We assessed the effects of NTFP harvesting (fruit harvest from canopy and lopping of branches for fruit) in combination with other common anthropogenic disturbances (cattle grazing, fire frequency and distance from village), in order to identify which stressors have greater effects on recruitment of three tropical dry forest fruit tree species. Specifically, we assessed the structure of 54 populations of Phyllanthus emblica, P. indofischeri and Terminalia chebula spread across the Nilgiri Biosphere Reserve, Western Ghats to ask: (1) How are populations recruiting? and (2) What anthropogenic disturbance and environmental factors, specifically forest type and elevation, are the most important predictors of recruitment status? We combined participatory research with an information-theoretic model-averaging approach to determine which factors most affect population structure and recruitment status. Our models illustrate that for T. chebula, high fire frequency and high fruit harvest intensity decreased the proportion of saplings, while lopping branches or stems to obtain fruit increased it. For Phyllanthus spp, recruitment was significantly lower in plots with more frequent fire. Indices of recruitment of both species were significantly higher for plots in more open-canopy environments of savanna woodlands than in dry forests.

    Forested wetlands dominated by Terminalia carolinensis are endemic to Micronesia but common only on the island of Kosrae, Federated States of Micronesia. On Kosrae, these forests occur on Nansepsep, Inkosr, and Sonahnpil soil types, which differ in degree of flooding and soil saturation. We compared forest structure, growth, nutrition, and regeneration on two sites each on Nansepsep and Inkosr soils and one site on the much less common Sonahnpil soil type. Terminalia tree sizes were similar on all three soil types, but forests differed in total basal area, species of smaller trees, and total plant species diversity. Terminalia regeneration was found only on the Inkosr soil type, which had the highest water table levels. Other Terminalia species are relatively light demanding, and T. carolinensis exhibited similar characteristics. It is therefore likely that Terminalia requires periodic, but perhaps naturally rare, stand-replacing disturbances (e.g., typhoons) in order to maintain its dominanace, except on the wettest sites, where competition from other species is reduced. Terminalia swamps in the Nansepsep soil type appeared to be at the greatest risk of conversion to other uses, but swamps on all three types may face reater pressure as Kosrae's population increases and the island's infrastrucure becomes more developed.

    Rheumatoid arthritis is a chronic degenerative autoimmune disease characterized by persistent inflammation of synovial membranes, which leads to cartilage destruction and bone erosion. To date, there are no effective therapies to slow the progress of this degenerative condition. Here, we evaluate the anti-arthritic effect of chebulanin, an abundant anti-inflammatory agent isolated from Terminalia chebula, in collagen induced arthritis in DBA/1 mice by intragastric administration. Arthritic severity was scored by performing histopathological evaluation of the joints and measuring the expression of inflammatory cytokines and relative enzymes by immunohistochemical staining. In parallel, bone destruction and erosion were confirmed by micro-CT. Our data revealed that chebulanin significantly improved the severity of arthritis. Specifically, the histopathological characteristics of the tissues were improved and expression of TNF-α, IL-6, MMP-3 and COX-2 in the paws and joints of the treated mice decreased in a dose-dependent manner compared with control mice. Furthermore, micro-CT analysis revealed that chebulanin induced a dose-dependent reduction in cartilage destruction and bone erosion. Taken together, our findings suggest that chebulanin suppresses the expression of inflammatory mediators and prevents cartilage destruction and bone erosion in mice. Therefore, chebulanin is a strong therapeutic alternative for the treatment of RA. PMID:26402786

    The antiamoebic effect of a crude drug formulation against Entamoeba histolytica was studied. In the traditional system of medicine in India, the formulation has been prescribed for intestinal disorders. It comprises of five medicinal herbs, namely, Boerhavia diffusa, Berberis aristata, Tinospora cordifolia, Terminalia chebula and Zingiber officinale. The dried and pulverized plants were extracted in ethanol together and individually. In vitro amoebicidal activity was studied to determine the minimal inhibitory concentration (MIC) values of all the constituent extracts as well as the whole formulation. The formulation had a MIC of 1000 micrograms/ml as compared with 10 micrograms/ml for metronidazole. In experimental caecal amoebiasis in rats the formulation had a curative rate of 89% with the average degree of infection (ADI) reduced to 0.4 in a group dosed with 500 mg/kg per day as compared with ADI of 3.8 for the sham-treated control group of rats. Metronidazole had a cure rate of 89% (ADI = 0.4) at a dose of 100 mg/kg per day and cured the infection completely (ADI = 0) when the dosage was doubled to 200 mg/kg per day. There were varying degrees of inhibition of the following enzyme activities of crude extracts of axenically cultured amoebae: DNase, RNase, aldolase, alkaline phosphatase, acid phosphatase, alpha-amylase and protease.

    Reported case was a 63-year-old female with end-stage osteoarthritis (OA) (Sandhigata Vata) of the left knee joint accompanied by exostoses. Radiology (X-ray) report confirmed it as a Kellgren-Lawrence grade III or less with exostoses. At the beginning, the Knee Society Rating System scores of pain, movement and stability were poor, and function score was fair. Srilankan traditional and Ayurveda medicine treatment was given in three regimens for 70 days. After 70 days, external treatment of oleation and 2 capsules of Shallaki (Boswellia serrata Triana and Planch) and two tablets of Jeewya (comprised of Emblica officinalis Gaertn., Tinospora cordifolia [Willd.] Millers. and Terminalia chebula Retz.), twice daily were continued over 5 months. Visual analogue scale for pain, knee scores in the Knee Society online rating system and a Ayurveda clinical assessment criteria was used to evaluate the effects of treatments in weekly basis. After treatment for 70 days, the Knee Society Rating System scores of pain, movement and stability were also improved up to good level and function score was improved up to excellent level. During the follow-up period, joint symptoms and signs and the knee scores were unchanged. In conclusion, this OA patient's quality of life was improved by the combined treatment of Sri Lankan traditional medicine and Ayurveda. PMID:26195904

    Drug discovery from complex mixture like Chinese herbs is a challenge and extensive false positives make the obtainment of specific bioactive compounds difficult. In the present study, a novel sample preparation method was proposed to rapidly reveal the specific bioactive compounds from complex mixtures using α-glucosidase as a case. Firstly, aqueous and methanol extracts of 500 traditional Chinese medicines were carried out with the aim of finding new sources of α-glucosidase inhibitors. As a result, the extracts of fruit of Terminalia chebula (FTC), flowers of Rosa rugosa (FRR) and Eugenia caryophyllata (FEC) as well as husk of Punica granatum (HPG) showed high inhibition on α-glucosidase. On-line liquid chromatography-diode array detection-tandem mass spectrometry and biochemical detection (HPLC-DAD-MS/MS-BCD) was performed to rapidly screen and characterize α-glucosidase inhibitors in these four extracts. After tentative identification, most of compounds with inhibitory activity in the investigated crude extracts were found to be tannins commonly recognized as non-specific enzyme inhibitors in vitro. Subsequently, the four extracts were treated with gelatin to improve specificity of the on-line system. Finally, two compounds with specific α-glucosidase inhibition were identified as corilagin and ellagic acid. The developed method could discover specific α-glucosidase inhibitors in complex mixtures such as plant extracts, which could also be used for discovery of specific inhibitors of other enzymes.

    Advanced glycation end-products (AGEs) are formed during normal aging, and at an accelerated rate in metabolic syndrome patients. Nonalcoholic steatohepatitis (NASH) can be caused by the AGEs in plasma, while glyceraldehyde-derived AGEs (glycer-AGEs) are significantly higher in the serum of NASH patients. In this study, we investigated the molecular mechanisms of chebulic acid, isolated from Terminalia chebula Retz., in the inhibition of glycer-AGEs induced production of reactive oxygen species (ROS) and collagen accumulation using the LX-2 cell line. Chebulic acid significantly inhibited the induction of ROS and accumulation of collagen proteins by glycer-AGEs. ERK phosphorylation and total nuclear factor E2-related factor 2 (Nrf2) protein expression were induced by chebulic acid in a dose-dependent manner. Chebulic acid was also found to induce translocation of Nrf2 into the nucleus, which was attenuated by inhibition of ERK phosphorylation through treatment with PD98059. Following translocation of Nrf2, chebulic acid induced the protein expressions of catalytic subunit of γ-glutamylcysteine synthetase and glutathione synthesis. Collagen accumulation was also significantly reduced by chebulic acid treatment. The observed effects of chebulic acid were all inhibited by PD98059 treatment. Taken together, these results suggest that chebulic acid prevents the glycer-AGEs-induced ROS formation of LX-2 cells and collagen accumulation by ERK-phosphorylation-mediated Nrf2 nuclear translocation, which causes upregulation of antioxidant protein production.

    The exposure to ultraviolet radiations (UVR) is the key source of skin sunburn; it may produce harmful entities, reactive oxygen species (ROS), leading to aging. The skin can be treated and protected from the injurious effects of ROS by using various pharmaceutical formulations, such as cream. Cream can be loaded with antioxidants to quench ROS leading to photo-protective effects. Moreover, modern medicines depend on ethnobotanicals for protection or treatment of human diseases. This review article summarizes various in vivo antioxidant studies on herbal creams loaded with phyto-extracts. These formulations may serve as cosmeceuticals to protect skin against injurious effects of UVR. The botanicals studied for dermatologic use in cream form include Acacia nilotica, Benincasa hispida, Calendula officinalis, Camellia sinensis, Camellia sinensis, Nelumbo nucifera, Capparis decidua, Castanea sativa, Coffea arabica, Crocus sativus, Emblica officinalis Gaertn, Foeniculum vulgare, Hippophae rhamnoides, Lithospermum erythrorhizon, Malus domestica, Matricaria chamomilla L., Moringa oleifera, Morus alba, Ocimum basilicum, Oryza sativa, Polygonum minus, Punica granatum, Silybum marianum, Tagetes erecta Linn., Terminalia chebula, Trigonella foenum-graecum, and Vitis vinifera. The observed anti-aging effects of cream formulations could be an outcome of a coordinating action of multiple constituents. Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed. PMID:26448818

Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed. PMID:26448818

  13. Traditional medicinal plants used for the treatment of diabetes in rural and urban areas of Dhaka, Bangladesh – an ethnobotanical survey

    PubMed Central

    2013-01-01

    Background The usage of medicinal plants is traditionally rooted in Bangladesh and still an essential part of public healthcare. Recently, a dramatically increasing prevalence brought diabetes mellitus and its therapy to the focus of public health interests in Bangladesh. We conducted an ethnobotanical survey to identify the traditional medicinal plants being used to treat diabetes in Bangladesh and to critically assess their anti-diabetic potentials with focus on evidence-based criteria. Methods In an ethnobotanical survey in defined rural and urban areas 63 randomly chosen individuals (health professionals, diabetic patients), identified to use traditional medicinal plants to treat diabetes, were interviewed in a structured manner about their administration or use of plants for treating diabetes. Results In total 37 medicinal plants belonging to 25 families were reported as being used for the treatment of diabetes in Bangladesh. The most frequently mentioned plants were Coccinia indica, Azadirachta indica, Trigonella foenum-graecum, Syzygium cumini, Terminalia chebula, Ficus racemosa, Momordica charantia, Swietenia mahagoni. Conclusion Traditional medicinal plants are commonly used in Bangladesh to treat diabetes. The available data regarding the anti-diabetic activity of the detected plants is not sufficient to adequately evaluate or recommend their use. Clinical intervention studies are required to provide evidence for a safe and effective use of the identified plants in the treatment of diabetes. PMID:23800215

    In India, since ancient times Tri-phalā (meaning "three fruits" in Sanskrit) has been considered to be a combination of the following fruits: -Harītakī (Terminalia chebula, Retz.), Āmalaka (Embelica officinalis Gaertn), and Vibhītaka (Terminalia belerica Roxb.). These plants are also listed in the Ayurvedic Pharmacopoeia of India. Harītakī and Āmalaka have also been used for medicinal purposes since ancient times in Japan under the Japanese names of (see text) (Kariroku) and (see text) (Annmaroku), respectively. Both have been carefully preserved as treasured drugs in the nationally important Shosoin treasure storehouse. This study attempts to clarify the description of Tri-phalā in the Nāvanītaka, which is the second part of the Bower Manuscript (Bower Ms.), and examines the reasons why these plants were combined. This paper begins with a summary description of Tri-phalā in the context of traditional Asian medicine, followed by the delineation of drug selection principles in Ayurveda. Tri-phalā formulas in the Nāvanītaka are then examined. The Carakasamhitā (CS) treats Tri-phalā as a purifier and tonic (rasāyana), describing it as a formula for rejuvenation and longevity. On the other hand, the Susrutasamhitd (SS) regards Tri-phalā as having the efficacy of balancing kapha (phlegm) and pitta (bile), and also as being a medicine to promote excretion and enhance digestive functions for better nutritional intake. It is described to have an effect of curing diseases by keeping the tridhāu (theree element) valance. Tri-phalā is thus used as an ingredient of laxatives for diseases that result from kapha imbalance and tonic. The Aşţāngahŗdayasamhitā (AHS) considers Tri-phalā to have a particular superiority among cure-all medicines with the power to dispel illness. It controls kapha and overcomes blood diseases. Tri-phalā formulas found in the Nāvanītaka were prescribed for the treatment of abdominal tumors induced by vāyu (wind) disorder

    2013-01-01

    Background Egyptians recognized the healing power of herbs and used them in their medicinal formulations. Nowadays, “Attarin” drug shops and the public use mainly the Unani medicinal system for treatment of their health problems including improvement of memory and old age related diseases. Numerous medicinal plants have been described in old literature of Arabic traditional medicine for treatment of Alzheimer’s disease (AD) (or to strengthen memory). Methods In this study, some of these plants were evaluated against three different preliminary bioassays related to AD to explore the possible way of their bio-interaction. Twenty three selected plants were extracted with methanol and screened in vitro against acetylcholinesterase (AChE) and cycloxygenase-1 (COX-1) enzymes. In addition, anti-oxidant activity using DPPH was determined. Results Of the tested plant extracts; Adhatoda vasica and Peganum harmala showed inhibitory effect on AChE at IC50 294 μg/ml and 68 μg/ml respectively. Moreover, A. vasica interacted reversibly with the enzyme while P. harmala showed irreversible inhibition. Ferula assafoetida (IC50 3.2 μg/ml), Syzygium aromaticum (34.9 μg/ml) and Zingiber officinalis (33.6 μg/ml) showed activity against COX-1 enzyme. Potent radical scavenging activity was demonstrated by three plant extracts Terminalia chebula (EC50 2.2 μg/ml), T. arjuna (3.1 μg/ml) and Emblica officinalis (6.3 μg/ml). Conclusion Interestingly, differential results have been obtained which indicate the variability of the mode of actions for the selected plants. Additionally, the reversible interaction of A. vasica against AChE and the potent activity of F. assafoetida against COX-1 make them effective, new and promising agents for treatment of AD in the future, either as total extracts or their single bioactive constituents.

Both the formulations responded significantly in both the wound models tested. The results were also comparable to that of the standard drug nitrofurazone used as a standard drug for comparison in this present investigation. The results were also comparable in terms of wound contracting ability, epithelization period, tensile strength and regeneration of tissues at the wound area. Thus, this investigation con fi rms the use of the Himax ointment and lotion containing Terminalia arjuna extract as a wound-healing agent as known from folklore medicine.

    In this study, we determined the genetic diversity of 126 isolates representing both Lasiodiplodia theobromae and Lasiodiplodia pseudotheobromae, collected from Theobroma cacao and Terminalia spp. in Cameroon, using simple sequence repeat (SSR) markers. SSR alleles showed clear genetic distinction between L. theobromae and L. pseudotheobromae, supporting their earlier separation as sister species. Both L. theobromae and L. pseudotheobromae populations from Cameroon had high levels of gene diversity, moderate degrees of genotypic diversity, and high levels of gene flow between isolates from T. cacao and Terminalia spp. There was no evidence for geographic substructure in these populations across the region studied, and the SSR alleles were randomly associated in both species, suggesting outcrossing.

    Single photon emission computed tomography (SPECT) allows studies of physiological or pathological processes. Red blood cells labeled with technetium-99m ( 99mTc-RBC) are used as a radiopharmaceutical in several evaluations. The radiolabeling efficiency and bioavailability of radiopharmaceuticals can be altered by natural/synthetic drugs and may induce pitfalls in the analysis of the nuclear medicine imaging. The labeling with 99mTc requires a reducing agent and stannous chloride (SnCl 2) is widely utilized. However, SnCl 2 presents a citotoxic and/or genotoxic potential in Escherichia coli ( E. coli) strains. The aim of this work was to evaluate the influence of aqueous extracts of Baccharis genistelloides (BG), Terminalia chebula (TC), Maytenus ilicifolia (MI), Cassia angustifolia (CA) and Equisetum arvense (EA) on (i) radiolabeling of blood constituents, (ii) bioavailability of sodium pertechnetate(Na 99mTcO 4) radiopharmaceutical, (iii) survival of E. coli. In vitro labeling of RBC was performed with blood ( Wistar rats) incubated with each extract, SnCl 2 and Na 99mTcO 4. Plasma (P) and blood cells (BC) were isolated, another aliquots precipitated and soluble (SF) and insoluble (IF) fractions isolated and counted. In the bioavailability of Na 99mTcO 4, Wistar rats were treated (7 days) with aqueous extract or with 0.9%NaCl, the radiopharmaceutical was administered, the animals sacrificed, the organs isolated, weighted and radioactivity counted. To evaluate the effect on the bacterial survival, E. coli was treated with: (a) SnCl 2; (b) 0.9% NaCl; (c) vegetal extract; or (d) SnCl 2 and vegetal extract. Radiolabeling efficiency showed a significantly decrease (ANOVA/Tukey post-test, p<0.05) after treatment with BG, TC, MI and CA extracts. The bioavailability results showed that the uptake of Na 99mTcO 4 was altered significantly (unpaired t-student test, p<0.05) in blood, lungs (CA/TC extracts), bone, heart, ovary (EA /TC), spleen, kidney (TC) , pancreas, thyroid

    The Shannoni complex consists of a group of sand fly species included in the subgenus Psathyromyia (Psathyromyia) Barretto, 1962, in which the females have banana-shaped spermathecae and the males have terminalia with digitiform parameres. The species included in the complex present morphological similarity, mainly among the females, and the males contribute most clearly to species differentiation. We describe a newspecies in the Shannoni complex, Psathyromyia baratai sp. n., on the basis of morphological and morphometric characters, a species which due to its great morphological similarity with Psathyromyia abonnenci, Psathyromyia limai, and Psathyromyia shannoni has been erroneously identified with one or other of them for >60 yr.

    Arjunolic acid, the major extractable constituent of the heavy wood of textit{Terminalia Arjuna}, has the potential to be used as a rigid and functional molecular framework for the construction of nanosized supramolecular architectures and nanomaterials. The nanosized triterpenoid, arjunolic acid, showed efficient gelation of various organic solvents at low concentrations. The low molecular mass gelator molecules self-assembled in the solvents to form fibers of nanometer diameters. The movement of the solvent molecules was hindered inside the fibrous network leading to the formation of a gel.

    Herbs have been used for medicinal purposes for centuries and known to possess antioxidant properties that may help to reduce the risk of chronic diseases, cardiovascular disease, and cancer. We screen aqueous extracts from 20 medicinal plants in Thailand that were believed to possess anti-tumor activity, help immune-stimulating property and maintain blood stasis. The antioxidant activities were investigated in two bioassays. Firstly, we demonstrated inhibition of Heinz bodies induction caused by oxidants under in vitro condition. The percentages of Heinz body inhibition activity in plant extracts from Terminalia citrina, Cassia timoriensis, and Derris elliptica were the highest followed by Anamirta cocculus, and Oroxylum indicum respectively. In addition, we investigated total antioxidant activity in plant extracts by improved ABTS radical cation decolorization assay. The total antioxidant activity of the extract from Terminalia citrina was also the highest activity followed by Ficus pubigera, Derris elliptica, Anamirta cocculus, Caesalpinia sappan, and Oroxylum indicum respectively. Our results suggest medicinal Thai plants as valuable sources of antioxidants, which may have a potential anti-carcinogenic activity. PMID:16435991

    Drosophilidae comprises more than 4,000 described species worldwide. Despite the huge number of papers published on the genus Drosophila Fallén, 1823, large parts of the family are still poorly known. The drosophiline genus Cladochaeta Coquillet, 1900 has more than 100 Neotropical and several southern Nearctic described species, but there is quite a large number of undescribed species. The Brazilian fauna of the genus was studied and 12 new species are herein described-Cladochaeta armatopsis nov. sp., C. balbiae nov. sp., C. paraitinga nov. sp., C. asapha nov. sp., C.chauliodactyla nov. sp., C. conicophallus nov. sp., C. dicrophallus nov. sp., C.grimaldii nov. sp., C. atlantica nov. sp., C. periotoi nov. sp., C. phallotrixa nov. sp. and C. stigmata nov. sp. We set the first record of C. arthrostyla Grimaldi & Nguyen, 1999 for northeastern Brazil a species otherwise known from Costa Rica, and the first record of C. bomplandi (Malloch, 1934) for the state of Minas Gerais, a species known for northeastern Argentina and southern Brazil. The descriptions include photographs for each species and detailed illustrations of the male terminalia in different views. A synopsis on the taxonomy and natural history of the genus is provided, as well as comments about the relationships of species in the genus, a discussion on problems of male terminalia sclerite homology and the problem of association between males and females.

This study assessed the survivability of Listeria monocytogenes and other food spoilage microbes (enterobacteriacea, molds and yeasts) in vacuum packaged soft cheese treated independently with Carica papaya (Vcpc), Terminalia cattapa (Vtcc) crude extracts, nisin (Vnc), and the combination of these three treatments (V+3) stored at 15 degrees C and 28 degrees C for a three week storage period. Vacuum packaging did not suppress Listeria monocytogenes, and there were no significant differences in the L. monocytogenes counts throughout the storage weeks (P > 0.05). The enterobacteriacea counts were suppressed to undetectable levels at 15 degrees C storage temperature by the third week of storage in all treatments except the Vnc and V+3. Molds and yeasts were undetectable in all treatments throughout the storage weeks. Significant differences occurred in the microbial count at the two storage temperatures and storage weeks (P < 0.05). It can therefore be concluded from this work that Vacuum packaging and addition of crude extracts (Carica papaya, Terminalia cattapa) in soft cheese storage can suppress enterobacteriacea, molds and yeasts. Food technologists developing industrialized 'wara should consider including these extracts and vacuum packaging in their production. Therefore, their use in extension of the shelf-life of soft cheese is recommended. PMID:23678645

    Several plant species are traditionally used in Brazil to treat various inflammatory diseases. Tumor necrosis factor- (TNF-) α and chemokine (C-C motif) ligand 2 (CCL2) are key inflammatory mediators in diseases like rheumatoid arthritis and atherosclerosis, respectively; nevertheless, only a few extracts have been assayed against these targets. We herein report the effect of 19 plant extracts on TNF-α and CCL2 release by lipopolysaccharide- (LPS-) stimulated THP-1 cells, a human monocytic leukemia cell line, along with their radical scavenging activity on DPPH. The extracts of Caryocar brasiliense, Casearia sylvestris, Coccoloba cereifera, and Terminalia glabrescens inhibited TNF-α production in a concentration-dependent manner. Fractionation of these extracts potentiated the anti-TNF-α effect, which was shown to concentrate in polar fractions, mainly composed by polyphenols. Significant CCL2 inhibition was elicited by Lippia sidoides and Terminalia glabrescens extracts, whose fractionation resulted in highly active low polar fractions. All assayed extracts showed strong radical scavenging activity, but antioxidant activity did not correlate with inhibition of TNF-α or CCL2 production. Our results allowed identifying extracts with selective capacity to block cytokine production; therefore, further purification of these extracts may yield molecules that could be useful in the treatment of chronic inflammatory diseases.

    All the species of Coenosia Meigen (Diptera, Muscidae) described by Fritz van Emden from the British Museum (Natural History) Ruwenzori Expedition of 1934-1935 (Emden 1940), supplemented by species from the Entomological Expedition to Abyssinia of 1926-1927 (Emden 1941), were studied, a total of 51 species. All types are deposited in the Natural History Museum, London, UK. For each species, a diagnosis is given and photographs of the 10 holotypes and of their labels are presented. Dissections and illustrations of the male terminalia were made when paratypes or identified specimens were available; all terminalia are described for the first time. One new synonym is proposed: C. kilembana (Emden, 1940) as a junior synonym of C. rebmanni Speiser, 1924; and three subspecies had their status revised and were elevated to species rank: C. brunneigena Emden, 1940, previously a subspecies of C. heterocnemis Emden, 1940; and C. albisquama (Emden, 1940) and C. argentescens (Emden, 1940), both previously subspecies of C. niveifrons (Stein, 1913).

    A wide variety of herbal remedies are used in traditional African medicine to treat inflammatory disorders, including some autoimmune diseases. Thirty-four extracts from 13 South African plant species traditionally used for the treatment of inflammation were investigated for their ability to control a microbial trigger for ankylosing spondylitis (Klebsiella pneumoniae). Twenty-six of the extracts (76.5%) inhibited the growth of K. pneumoniae. Methanol and water extracts of Ballota africana, Carpobrotus edulis leaves, Kigellia africana, Lippia javanica, Pelargonium fasiculata, Syzygium cordatum (including bark), Terminalia pruinoides and Terminalia sericea were effective K. pneumoniae inhibitors, with MIC values <1000 µg/ml. The roots of Tulbaghia violaceae and bark from Warburgia salutaris also demonstrated efficacy. The most potent extracts were examined by RP-HPLC and UV-Vis spectroscopy for the presence of resveratrol. Methanolic extracts of B. africana, C. edulis leaves, L. javanica, T. pruinoides and T. sericea, as well as aqueous B. africana, T. pruinoides and T. sericea extracts, displayed peaks with retention times and UV-Vis spectra consistent with the presence of resveratrol. Resveratrol was generally a minor component, indicating that resveratrol was not solely responsible for the anti-Klebsiella growth inhibitory properties. Plant extracts with K. pneumoniae inhibitory activity were either non-toxic, or of low toxicity in the Artemia (brine shrimp) nauplii bioassay. Their low toxicity and antibiotic bioactivity against K. pneumoniae indicate their potential for both preventing the onset of ankylosing spondylitis and minimising its symptoms once the disease is established.

    A wide variety of herbal remedies are used in traditional African medicine to treat rheumatoid arthritis (RA) and inflammation. Thirty-four extracts from 13 South African plant species with a history of ethnobotanical usage in the treatment of inflammation were investigated for their ability to control two microbial triggers for RA (Proteus mirabilis and Proteus vulgaris). Twenty-nine of the extracts (85.3 %) inhibited the growth of P. mirabilis and 23 of them tested (67.7 %) inhibited the growth of P. vulgaris. Methanol and water extracts of Carpobrotus edulis, Lippia javanica, Pelargonium viridflorum, Ptaeroxylon obliquum, Syzygium cordatum leaf and bark, Terminalia pruinoides, Terminalia sericea, Warburgia salutaris bark and an aqueous extract of W. salutaris leaf were effective Proteus inhibitors, with MIC values <2,000 μg/ml. The most potent extracts were examined by Reverse phase high performance liquid chromatography and UV-Vis spectroscopy for the presence of resveratrol. Only extracts from T. pruinoides and T. sericea contained resveratrol, indicating that it was not responsible for the anti-Proteus properties reported here. All extracts with Proteus inhibitory activity were also either non-toxic, or of low toxicity in the Artemia nauplii bioassay. The low toxicity of these extracts and their inhibitory bioactivity against Proteus spp. indicate their potential for blocking the onset of rheumatoid arthritis. PMID:23877712

    A total of 418 healers have been interviewed in Guinea, a coastal country of West Africa, ranging between 7 degrees 30 and 12 degrees 30 of northern latitude and 8 degrees and 15 degrees of western longitude. Plant species used by the local inhabitants to treat infectious diseases were identified using ethnobotanical, ethnographic and taxonomic methods. During these investigations, 218 plants were registered, of which the following were the most frequently used: Erythrina senegalensis, Bridelia ferruginea, Crossopteryx febrifuga, Ximenia americana, Annona senegalensis, Cochlospermum tinctorium, Cochlospermum planchonii, Lantana camara, Costus afer, Psidium guajava, Terminalia glaucescens, Uapaca somon and Swartzia madagascariensis. Most plants, and especially the leaves, were essentially used as a decoction. In order to assess antibacterial activity, 190 recipes were prepared and biologically tested, among which six showed activity (minimal inhibitory concentration<125 microg/ml) against Bacillus cereus, Mycobacterium fortuitum, Staphylococcus aureus, or Candida albicans, i.e., Entada africana, Chlorophora regia, Erythrina senegalensis, Harrisonia abyssinica, Uvaria tomentosa, and a mixture of six plants consisting of Swartzia madagascariensis, Isoberlinia doka, Annona senegalensis, Gardenia ternifolia, Terminalia glaucescens and Erythrina senegalensis.

    Ethanol extract of Terminalia pallida Brandis. (EETP) was evaluated for its anti-ulcer activity against various models of ulcers, such as drug-induced ulcers, histamine-induced ulcers and ethanol-induced ulcers in Swiss albino rats. The EETP at the doses of 250 and 500 mg/kg per os (p.o.) exhibited significant protection against ulcers produced by indomethacin, histamine and the effect was comparable to that of the reference drug famotidine (30 mg/kg b.w) orally. The extract also afforded significant protection against ethanol-induced gastric ulceration. Meanwhile, EETP significantly lowered the elevated lipid peroxide level (thiobarbituric acid reactive substances (TBARS)) and restored the altered glutathione level in ethanol-induced gastric ulceration. The present investigation revealed that the EETP exhibited significant anti-ulcer activity by enhancing antioxidant potential of the gastric mucosa, thereby reducing mucosal damage.

    Medicinal plants play an important role in health care. The use of medicinal plants for treatment is growing in view of cost and non-compliance of modern medicine as in case of non-communicable diseases. Plants such as Boswellia, ovalifoliolata, Cycas beddomei, Pimpinella tirupatiensis, Pterocarpus santalinus, Shorea thumbuggaia, Syzygium alternifolium, Terminalia pallida are endemic to Tirumala hills of seshachalam range falling under the Eastern Ghats of India. These plants species have medicinal properties such as anti-tumorogenic, anti-microbial, purgative, hypoglycemic, abortificient, analgesic, anti-septic, anti-pyretic and anti-inflammatory. We created a database named DEPTH in an attempt to communicate data of these plants to the scientific community. DEPTH contains data on scientific name, vernacular name, family name, morphological description, economic importance, known medicinal compounds and medicinal importance.

    Restoration of a highly degraded forest, which had lost its natural capacity for regeneration, was attempted in the Nanmangalam Reserve Forest in Eastern Ghats of India. In field experiment, 12 native tree species were planted. The restoration included inoculation with a consortium of 5 native plant growth-promoting bacteria (PGPB), with the addition of small amounts of compost and a chemical fertilizer (NPK). The experimental fields were maintained for 1080 days. The growth and biomass varied depending on the plant species. All native plants responded well to the supplementation with the native PGPB. The plants such as Pongamia pinnata, Tamarindus indica, Gmelina arborea, Wrightia tinctoria, Syzygium cumini, Albizia lebbeck, Terminalia bellirica, and Azadirachta indica performed well in the native soil. This study demonstrated, by using native trees and PGPB, a possibility to restore the degraded forest. PMID:27195310

Different extraction solvents (acetone, methanol, ethanol, and water) were used and extracts were examined against Bacillus cereus, Serratia sp., Rhodotorula mucilaginosa, Aspergillus flavus, and Penicillium citrinum isolated from juices. Extracts from the medicinal herb and spices have significant activity. B. cereus was the most sensitive and R. mucilaginosa was the most resistant among the microorganisms tested. Ethanolic and methanolic extract of C. asiatica displayed maximum diameter of inhibition zone against bacteria and yeast and percentage mycelial inhibition against moulds. This study confirmed the potential of selected extracts of spices as effective natural food preservative in juices. PMID:26880927

    Philornis Meinert is a very interesting Muscidae (Diptera) genus whose larvae are associated with a wide range of bird species. The existing description of Philornis seguyi Garcia (1952), which was reported in Argentina, so far involves only the female. During the 2000-2002 breeding seasons, we collected Philornis flies from six bird species in Buenos Aires province, Argentina. All the flies were identified as P. seguyi. Based on this material, we describe the larva, puparium, adult male, and male and female terminalia. All the host associations presented here--Mimus saturninus (Mimidae), Troglodytes aedon (Troglodytidae), Pitangus sulfuratus (Tyrannidae), Pyrocephalus rubinus (Tyrannidae), Satrapa icterophrys (Tyrannidae) and Molothrus bonariensis (Icteridae) in nests of M. saturninus and Troglodytes aedon--are new for P. seguyi.

    A taxonomic revision based on the study of the external morphology and the terminalia of Phygopoda Thomson, 1864 and Pseudophygopoda Tavakilian & Peñaherrera-Leiva, 2007 is presented. The genera and their species are redescribed. Five synonymies are proposed: Panamapoda Clarke, 2014 and Paraphygopoda Clarke, 2014 = Pseudophygopoda Tavakilian & Peñaherrera-Leiva, 2007; Paraphygopoda viridimicans (Fisher, 1952); Paraphygopoda nappae Clarke, 2014; and Paraphygopoda longipennis (Zajciw, 1963) = Pseudophygopoda albitarsis (Klug, 1825).

    Abstract New genus Neoethilla gen. n., is described to include two New World nominal species formerly recognized as valid species in Winthemia Robineau-Desvoidy: Exorista ignobilis van der Wulp and Winthemia antennalis Coquillett. Winthemia antennalis is proposed as a junior synonym of Exorista ignobilis syn. n. Neoethilla ignobilis comb. n. is removed from the Winthemiini and placed in the tribe Ethillini (Exoristinae) based on a study of the external features of adults, male terminalia, female reproductive system, and egg morphology. The small tribe Ethillini, not hitherto known from the New World, currently comprises fourteen genera worldwide. The phylogeny and systematics of the Ethillini and their relationships with related tribes are discussed and documented by descriptions and illustrations of relevant character states. PMID:23378795

    Two new, brachypterous species of Limnellia are described from specimens collected in the Venezuelan Andes: L. vounitis (Trujillo: Bocon, La Cristalina (Andes; 09°14.7'N, 70°19.1'W; 2500 m)) and L. flavifrontis (Mérida: Mérida, Sierra Nevada National Park (Laguna Negra; 8°47.1'N; 70°48.4'W; 3300 m)). To facilitate identification of these unusual species, we have included a diagnosis of the tribe Scatellini and of the genus Limnellia and have also provided an annotated key to the South American genera of this tribe. The descriptions are supplemented with illustrations, photographs, and scanning electron micrographs of external structures and structures of the male terminalia. PMID:27470858

    The 55 known species of Coniceromyia are herein revised. Three new species from the Atlantic Forest in Brazil are described-C. apioneura, sp.nov., C. neofusca, sp.nov. and C. tanycrossa, sp.nov.-and fourteen species are redescribed. Most of the species have foreleg, wing, hind femur, and male terminalia illustrated. Characters previously unnoticed are described for the first time. Coniceromyia cubensis Brues, previously accepted as a synonym of C. latimana (Malloch), has its status reinstated. Taxonomic problems in the genus are addressed, including the condition of the damaged holotypes of C. boliviana Borgmeier and C. vespertilio Schmitz, and our inability to associate males with the female holotypes of C. arizonensis Borgmeier, C. fusca Borgmeier and C. grenadensis (Brues). The holotypes of Coniceromyia angularis Borgmeier & Prado and Coniceromyia laticosta Prado are considered to be lost. PMID:27394322

    We aimed to evaluate therapeutic potential of arjunolic acid (AA), in Terminalia Arjuna bark, on Ehrlich Ascites carcinoma (EAC) in-vivo and in-vitro. EAC was induced in fifty female Swiss albino mice. Two doses of AA was used 100 and 250mg/kg. Arjunulic acid reduced tumor volume and cells count. AA decreased EAC cells viability and increased cell toxicity. Moreover, AA reduced TNF-α, IL-1β, TGF-β, TGF-β type I receptor and latency-associated peptide levels associated with elevated IL-10 in-vivo and in-vitro. In conclusion, AA produced antitumor activity against EAC by increasing cytotoxicity and apoptosis and partially blocking the TGF-βR1 and affecting inflammatory cytokine levels. PMID:27470335

    In the present investigation, comparison of antimicrobial activities of different spices, Curcuma longa, Zingiber officinale, and Mentha arvensis, and medicinal herbs, such as Withania somnifera, Rauvolfia serpentina, Emblica officinalis, Terminalia arjuna, and Centella asiatica, was evaluated. Different extraction solvents (acetone, methanol, ethanol, and water) were used and extracts were examined against Bacillus cereus, Serratia sp., Rhodotorula mucilaginosa, Aspergillus flavus, and Penicillium citrinum isolated from juices. Extracts from the medicinal herb and spices have significant activity. B. cereus was the most sensitive and R. mucilaginosa was the most resistant among the microorganisms tested. Ethanolic and methanolic extract of C. asiatica displayed maximum diameter of inhibition zone against bacteria and yeast and percentage mycelial inhibition against moulds. This study confirmed the potential of selected extracts of spices as effective natural food preservative in juices. PMID:26880927

    Restoration of a highly degraded forest, which had lost its natural capacity for regeneration, was attempted in the Nanmangalam Reserve Forest in Eastern Ghats of India. In field experiment, 12 native tree species were planted. The restoration included inoculation with a consortium of 5 native plant growth-promoting bacteria (PGPB), with the addition of small amounts of compost and a chemical fertilizer (NPK). The experimental fields were maintained for 1080 days. The growth and biomass varied depending on the plant species. All native plants responded well to the supplementation with the native PGPB. The plants such as Pongamia pinnata, Tamarindus indica, Gmelina arborea, Wrightia tinctoria, Syzygium cumini, Albizia lebbeck, Terminalia bellirica, and Azadirachta indica performed well in the native soil. This study demonstrated, by using native trees and PGPB, a possibility to restore the degraded forest. PMID:27195310

    To determine antioxidant phenolics and flavonoids in commonly consumed Indian foods we chemically analysed 85 food-stuffs comprising of cereals, pulses, nuts, oilseeds, vegetables, fruits and beverages. Total phenolics were measured biochemically and flavonoids were measured as a sum of quercetin, kaempferol, luteolin and pelargonidin. High flavonoid content (> 100 mg/100 gm) was present in tea, coffee, apple, guava, terminalia bark, fenugreek seeds, mustard seeds, cinnamon, red chili powder, cloves and turmeric. Medium levels (50-100 mg) were found in Indian gooseberry, omum, cumin, cardamom, betel leaf and brandy. Small but significant amounts were also present in food-items of large consumption such as kidney beans, soyabeans, grapes, ginger, coriander powder, bajra and brinjal. PMID:11229280

    Comprehensive management of sexually transmitted infections (STIs) using vaginal or rectal microbicide-based intervention is one of the strategies for prevention of HIV infection. Herbal products have been used for treating STIs traditionally. Herein, we present in vitro activity of 10 plant extracts and their 34 fractions against three sexually transmitted/reproductive tract pathogens - Neisseria gonorrhoeae, Haemophilus ducreyi and Candida albicans. The plant parts were selected; the extracts/fractions were prepared and screened by disc diffusion method. The minimum inhibitory and minimum cidal concentrations were determined. The qualitative phytochemical analysis of selected extracts/fractions showing activity was performed. Of the extracts/fractions tested, three inhibited C. albicans, ten inhibited N. gonorrhoeae and five inhibited H. ducreyi growth. Our study demonstrated that Terminalia paniculata Roth. extracts/fractions inhibited growth of all three organisms. The ethyl acetate fraction of Syzygium cumini Linn. and Bridelia retusa (L.) Spreng. extracts was found to inhibit N. gonorrhoeae at lowest concentrations. PMID:25427632

    The aim of this study was to evaluate if fluoride pollution found in 1996 in Cubatão, SP, Brazil, using the vegetation as biomarker, changed in the last ten years. Leaves of Terminalia cattappa located at the industrial area around the industries of fertilizers and in the urban area of the city were collected in 1996 and 2006. They were dried, powdered and fluoride water soluble extracted was analyzes with specific electrode. The fluoride concentration in the leaves around fertilizer industries was 12 times greater than that found in the urban area, either in 1996 or 2006, respectively. The data suggest that in the last ten years the environmental pollution by fluoride in Cubatão has not improved. PMID:20069189

    Background The cave fauna of the Brazil is poorly documented, and among the insects those live or frequent caves and their adjacent environments phlebotomine sand flies call for special attention because several species are vectors of pathogens among vertebrates hosts. A new species of sand fly from Minas Gerais is described based in females and males collected in a cave of the municipality of Lassance. Results The morphological characters of the new species permit to include in the Evandromyia genus, cortelezzii complex. This complex consists of three species: Evandromyia corumbaensis (Galati, Nunes, Oshiro & Rego, 1989), Evandromyia cortelezzii (Brethes, 1923) and Evandromyia sallesi (Galvao & Coutinho, 1940). Conclusions The new species can be separate from the others of the cortelezzii complex through morphological characters of the male terminalia and female spermathecae. PMID:21827682

    Phasmatodea, more commonly known as stick insects, have been poorly studied at the molecular level for several key traits, such as components of the sensory system and regulators of reproduction and development, impeding a deeper understanding of their functional biology. Here, we employ de novo transcriptome analysis to identify genes with primary functions related to female odour reception, digestion, and male sexual traits in the New Zealand common stick insect Clitarchus hookeri (White). The female olfactory gene repertoire revealed ten odorant binding proteins with three recently duplicated, 12 chemosensory proteins, 16 odorant receptors, and 17 ionotropic receptors. The majority of these olfactory genes were over-expressed in female antennae and have the inferred function of odorant reception. Others that were predominantly expressed in male terminalia (n = 3) and female midgut (n = 1) suggest they have a role in sexual reproduction and digestion, respectively. Over-represented transcripts in the midgut were enriched with digestive enzyme gene families. Clitarchus hookeri is likely to harbour nine members of an endogenous cellulase family (glycoside hydrolase family 9), two of which appear to be specific to the C. hookeri lineage. All of these cellulase sequences fall into four main phasmid clades and show gene duplication events occurred early in the diversification of Phasmatodea. In addition, C. hookeri genome is likely to express γ-proteobacteria pectinase transcripts that have recently been shown to be the result of horizontal transfer. We also predicted 711 male terminalia-enriched transcripts that are candidate accessory gland proteins, 28 of which were annotated to have molecular functions of peptidase activity and peptidase inhibitor activity, two groups being widely reported to regulate female reproduction through proteolytic cascades. Our study has yielded new insights into the genetic basis of odour detection, nutrient digestion, and male sexual

Of the nine genera, Setacera Cresson, Cirrula Cresson, Dimecoenia Cresson, Paracoenia Cresson and Ephydra Fallén are mostly temperate in distribution, primarily in the Northern Hemisphere. The other four genera, which are exclusively Neotropical, include two, Austrocoenia and Notiocoenia, that were treated previously in the tribe Scatellini, and two recently described genera: Paraephydra (type species: Paraephydra freitasi (Oliveira)) and Neoephydra (type species: Neoephydra araucaria Mathis). New species described herein are: Neoephydra neotropica (Chile), N. dasycephala (Argentina and Peru), N. mallonota (Argentina, Bolivia, and Chile), N. shewelli (Argentina, Bolivia, and Chile), N. inca (Argentina, Bolivia, Peru), N. penai (Chile) and N. trichina (Argentina and Chile). New synonyms are (cited in their original combinations): Ephydra densepilosa Hendel = E. ciligena Rondani, Dimecoenia grumanni Oliveira = E. ciligena Rondani, D. coltaensis Cresson = D. zurcheri Hendel, D. carrerai Oliveira = D. zurcheri Hendel, D. lopesi = E. ciligena Rondani, D. travassosi Mello and Oliveira = E. prionoptera Thomson. A neotype is designated for E. caesia Wulp, and the following lectotype designations have also been made to better stabilize nomenclature (here cited in their original combination): Ephydra chilensis Macquart, Ephydra densepilosa Hendel, Ephydra pravoneura Hendel, Ephydra prionoptera Thomson, and Dimecoenia zurcheri Hendel. Dimecoenia venteli Oliveira is listed as a species inquirenda, as the type series includes only female specimens that we cannot presently recognize. Although the genera and subgenera are fairly easily distinguished, the included species are frequently difficult to separate, and we have generally relied on characters of the male terminalia to determine a species identity.

    The purpose of this study was to evaluate the antibacterial, antifungal and antioxidant activities of medicinal plants. The antibacterial activity of methanolic extracts of three medicinal plants (Swertia chirata, Terminalia bellerica and Zanthoxylum armatum) were tested against Gentamicin (standard drug) on eleven gram positive and seventeen gram negative bacteria by agar well method. It was revealed that seven-gram negative and six gram positive bacterial species were inhibited by these plant extracts. Minimum inhibitory concentrations (MIC) of the extracts were determined by broth micro-dilution method. The significant MIC value of Swertia chirata was 20mg/ml against Serratia marcesens, Zanthoxylum armatum was 10 mg/ml against Aeromonas hydrophila and Terminali bellerica was 20mg/ml against Acinetobacter baumanii as well as Serratia marcesens. Antifungal screening was done for methanolic extracts of these plants by agar well method with the 6 saprophytic, 5 dermatophytic and 6 yeasts. In this case Griseofulvin was used as a standard. All saprophytes and dermatophytes were showed resistance by these plants extracts except Microsporum canis, which was inhibited by Z. armatum and S. chirata extracts. The significant MIC value of Zanthoxylum armatum was 10mg/ml against Microsporum canis and Swertia chirata was 10mg/ml against Candida tropicalis. The anti-oxidant study was performed by DPPH free radical scavenging assay using ascorbic acid as a reference standard. Significant antioxidant activities were observed by Swertia chirata and Zanthoxylum armatum at concentration 200μg/ml was 70% DPPH scavenging activity (EC50=937.5μg/ml) while Terminalia bellerica showed 55.6% DPPH scavenging activity (EC50=100μg/ml). This study has shown that these plants could provide potent antibacterial compounds and may possible preventive agents in ROS related ailments.

    This study demonstrates the potentials of Geographic Information System (GIS) as a management tool for avenue trees (Street trees) populations in small communities (using Idi-Ishin community, Ibadan, Nigeria as a case study). GIS is a decision support system which integrate data or set of data from different sources, bringing them under the same referencing system in a computer system. An Ikonos Imagery (1m Spatial Resolution) of the study area was digitized to produce a digital map using ArcGIS 10.1 version. The avenue trees species ≥ 5cm diameter at breast height (DBH) was selected for enumeration. These trees were then measured and tagged. The Height, Girth and Geographic location (X &Y coordinate) of the trees were measured with Haga altimeter, Girthing tape and Hand held Global Positioning System (GPS) respectively. The species and families of the trees enumerated were also identified. Data were analysed for basal area (BA) and volume (V). A total number of 43 avenue trees were assessed in Idi-Ishin Community. Roystonea regia accounted for the majority of the avenue trees (25.58%), followed by Polyanthia longiflora (23.26%), Gliricida seprium (20.93%), Eucalyptus toreliana (13.95%), Delunix regea (6.98%). However Terminalia catapa, Terminalia radii, Azadrachita indica and Newbodia levis had the same abundance of 2.33%. It was also observed that the benefits derived from these avenue trees includes; Carbon sequestration, Beautification, Wind break and shade. A spatial relational database was created for the assessed avenue trees using ArcCatalog of ArcGIS 10.1 version. Based on the findings from the study (which serves as baseline information for the management of the avenue trees in the study area), it was therefore recommended that subsequent assessment should be carried out at 3-5 year interval in other to ensure proper and continuous monitoring and updating of the data.

    The Nearctic fauna of the genus Callomyia Meigen is revised and a phylogeny of the world species, based on morphological characters, is presented. Although morphological data are used primarily to delimit species, molecular sequence data (DNA barcodes) are used where possible, to help determine species boundaries and associate sexes. Species descriptions, diagnoses, and distribution maps are presented, along with illustrations of habitus, male terminalia, and additional important diagnostic characters. A key to the Nearctic species is provided. Ten species are recorded from the Nearctic Region including three new species: C. argentea Cumming sp. nov., C. arnaudi Cumming sp. nov., C. bertae Kessel, C. browni Cumming sp. nov., C. calla Kessel, C. corvina Kessel, C. gilloglyorum Kessel, C. proxima Johnson, C. velutina Johnson, and C. venusta Snow. The female of C. velutina is described, and three new synonyms are proposed: C. cleta Kessel is a junior synonym of C. calla syn. nov.; C. clara Kessel is a junior synonym of C. corvina syn. nov.; and C. liardia Kessel & Buegler is a junior synonym of C. proxima syn. nov. Phylogenetic relationships within the genus are reconstructed. The genus is monophyletic based primarily on the setulose R1 wing vein, female antennal size and three larval characters. The Nearctic species do not form a monophyletic group with respect to the Old World species. PMID:27395101

    The eco-friendly approach for the green synthesis of silver nanoparticles (SNP) using Terminalia bellirica (T. bellirica) fruit extract is reported herein. Initially formation of SNP was noticed through visual color change from yellow to reddish brown and further analyzed by surface plasmonic resonance (SPR) band at 429 nm using UV-Vis spectroscopy. Identification of different polyphenols present in T. bellirica extract was done using High Pressure Liquid Chromatography (HPLC). Aqueous T. bellirica extract contains high amount of gallic acid which is major secondary metabolite responsible for the reduction and stabilization process. It was established by analyses of extracts before and after reduction using HPLC. Formation of spherical SNP was characterized by Transmission Electron Microscopy (TEM) analysis. X-ray Diffraction (XRD) study revealed crystalline nature of SNP. Presence of different functional groups on the surface of SNP was evidenced by Fourier Transform Infrared Spectroscopy (FTIR) study. A plausible mechanism of reduction and stabilization processes involved in the synthesis of stable SNP was also explained based on HPLC and FTIR data. In addition, the synthesized SNP was tested for antibacterial and antioxidant activities. SNP showed good antimicrobial activity against both gram positive (S. aureus) and gram negative (E. coli) bacteria. It also showed good antioxidant activity compared to ascorbic acid as standard antioxidant by using standard DPPH method.

    Objectives: Screening of the medicinal plants and determination of minimum inhibitory concentration (MIC) against Vibrio cholerae and Vibrio parahaemolyticus. Materials and Methods: A simple in vitro screening assay was employed for the standard strain of Vibrio cholerae, 12 isolates of Vibrio cholerae non-O1, and Vibrio parahaemolyticus. Aqueous and organic solvent extracts of different parts of the plants were investigated by using the disk diffusion method. Extracts from 16 medicinal plants were selected on account of the reported traditional uses for the treatment of cholera and gastrointestinal diseases, and they were assayed for vibriocidal activities. Results: The different extracts differed significantly in their vibriocidal properties with respect to different solvents. The MIC values of the plant extracts against test bacteria were found to be in the range of 2.5-20 mg/ml. Conclusions: The results indicated that Lawsonia inermis, Saraca indica, Syzygium cumini, Terminalia belerica, Allium sativum, and Datura stramonium served as broad-spectrum vibriocidal agents.

    Abstract European species of the Mycetophila ruficollis group are compared on the basis of morphology and sequences of mitochondrial cytochrome oxidase subunit one (COI) and the ITS2 region of nuclear ribosomal DNA. The study represents the first evaluation of morphology-based species delimitation of closely related fungus gnat species by applying molecular information. Detailed descriptions and illustrations of the male terminalia are presented along with a key for the identification of all nine European species of the group. Phylogenetic analyses of molecular data generally supported the morphological species discrimination. The barcoding region of COI superseded ITS2 rDNA in resolving species. In the COI barcoding region interspecific differences ranged from 2.9 to 10.6% and the intraspecific distance from 0.08 to 0.8%. Only COI data distinguished between the similar and closely related Mycetophila ichneumonea and Mycetophila uninotata of which the latter was observed to include cryptic species. The host range of some species is suggested to be narrower than previously considered and to depend on the forest type. Presented evidence indicates the importance of analysing sequence data of morphologically very similar mycetophages reared from identified host fungi for elucidating species delimitation as well as their geographic and host ranges. New country records, viz. Estonia for Mycetophila evanida, Georgia for Mycetophila ichneumonea, Mycetophila idonea and Mycetophila ruficollis, and Norway for Mycetophila strobli, widen the known distribution ranges of these species.

    The generation of organic-inorganic hybrid materials from renewable resources and their utilization in basic and applied areas has been at the forefront of research in recent years for sustainable development. Herein, a novel organic-inorganic trihybrid material was synthesized by in situ generation of palladium nanoparticles (PdNPs) in a hybrid gel matrix based on renewable chemicals. Constituents of the hybrid gel included a pentacyclic triterpenoid arjunolic acid extractable from Terminalia arjuna and the leaf extract of Chrysophyllum cainito rich in flavonoids. We took advantage of the presence of flavonoid molecules in this hybrid gel to generate an advanced trihybrid gel through in situ reduction of doped Pd(II) salts to stable PdNPs. The xerogel of this trihybrid material was used as a recyclable heterogeneous catalyst for C-C coupling and reduction reactions in aqueous media. We also demonstrated that the in situ generated PdNPs containing trihybrid material was a more efficient catalyst than the trihybrid material generated with presynthesized PdNPs. PMID:27511441

    A polyherbal formulation consisting of different proportions of Commiphora mukul (Hook ex Stocks) Eng., Salacia reticulata Wight, Terminalia arjuna (Roxb.) Wight & Arn, and Curcuma longa Linn extracts was tested for free-radical scavenging and anti-lipid peroxidative effects on serum and platelets in vitro. The most active formulation (GSTC3) was evaluated for its hypolipidemic potential on a high-fat, high-cholesterol diet (HFD) fed to male Wistar rats for a period of 45 days. At a dose of 100 mg/kg body weight, GSTC3 decreased serum total cholesterol, low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), triglycerides, and phospholipids similar to standard atorvastatin while maintaining high-density lipoprotein (HDL) at normal levels. Significantly lower levels of thiobarbituric acid-reactive substances (TBARS) were observed in both the liver and sera of rats treated with GSTC3. Although the phospholipid levels in liver remained unchanged, lower values of LDL, VLDL, and atherogenic index of plasma as well as higher HMG-CoA/ mevalonate ratios suggested a significant hypolipidemic effect for GSTC3, possibly by partial inhibition of HMG-CoA reductase activity. The histopathological analysis of liver tissue did not reveal lipid accumulation or indicate tissue damage. Overall, the results of this study suggest the hypolipidemic and anti-atherogenic efficacy of a nontoxic herbal formulation. PMID:26349606

    Aim: The aim of this study was to understand traditional knowledge of tick ecology and remedies for tick-borne diseases (TBDs) among the Maasai people in northern Tanzania. Materials and Methods: Semi-structured interviews were conducted among specific groups likely to be knowledgeable about tick ecology and TBDs in livestock among the Maasai people. Results: A total of 25 plant species belonging to 18 families were used to treat 8 different TBDs of livestock. Most of the plant species used were of Fabaceae and Burseraceae families. Aloe volkensii, Cissus grandifolia, and Terminalia brownii were the most commonly used plant species. The major plant growth form used was trees, while stems and bark were the main plant parts used. Most treatments were taken orally. Conclusion: Maasai people have substantial knowledge on tick ecology exemplified by their ability to differentiate between different tick species and the range of remedies for each of the TBDs. Because traditional ethnoveterinary remedies are frequently utilized, their effectiveness should be further investigated. PMID:27065643

    Objective: To investigate the aphrodisiac potential of polyherbal formulations prepared from different parts of Tribulus terrestris, Curculigo orchioides, Allium tuberosum, Cucurbita pepo, Elephant creeper, Mucuna pruriens, and Terminalia catappa in Albino rats in specified ratio as suspension. Materials and Methods: The different concentrations of prepared polyherbal formulations i.e. 150, 300, and 600 mg/kg and sildenafil citrate as standard (5 mg/kg) and vehicle (control) were administered orally to rats (n = 6 animals per group) for 3 weeks. Mating behavior parameters in male rats was monitored in first week and third week week of treatment pairing with receptive females. After termination of drug treatment, the mating performance, hormonal analysis, sperm count, and testes-body weight ratio were also evaluated. Results: The polyherbal formulation showed a significant increase in mating behavior as well as mating performance, serum hormonal levels, sperm count, and testes-body weight ratio with dose-dependent relationship as compared to vehicle control. But the dose of 600 mg/kg of polyherbal formulation assumes closer resemblance of above parameters with the standard used. Conclusion: The results of the study strongly suggest that the polyherbal formulations have a good aphrodisiac activity on rats in the above experimental models, which may be an alternative weapon for various sexual dysfunctions in future.

    Fifty-seven Thai herbs and spices were examined for their retroviral reverse transcriptase inhibitory activity. All herbs and spices were extracted with hot-water and methanol. Reverse transcriptase inhibitory activity of the extracts was determined by using Moloney Murine Leukemia Virus reverse transcriptase (M-MuLV-RT) reacted with 3H-dTTP and radioactivity measured with a scintillation counter. Eighty-one per cent (46/57) of hot-water extracts and 54% (31/57) of methanol extracts showed inhibitory activities. At a concentration of 125 micrograms/ml, 13% (6/46) of hot-water extracts, namely Eugenia caryophyllus Bullock et Harrison, Phyllanthus urinaria Linn., Terminalia belerica Roxb., Nelumbo nucifera Gaertn., Psidium guajava Linn. and Lawsonia inermis Linn., had a relative inhibitory ratio (IR) over 50%. They showed ratios of 100%, 91%, 75%, 74%, 61% and 60%, respectively. For methanol extracts, only 10% (3/31) had IR values over 50%. They were T. belerica, E. caryophyllus and N. nucifera which exhibited IR values of 83%, 54% and 54%, respectively. PMID:7524165

    The purpose of this study was to evaluate the physical and mechanical properties of particleboard made with pruning wastes from Ipê (Tabebuia serratifolia) and Chapéu-de-Sol (Terminalia catappa) trees. Particleboards were prepared with both wood species, using all the material produced by grinding the pruning wastes. The particleboards had dimensions of 45 × 45 cm, a thickness of approximately 11.5 mm and an average density of 664 kg/m3. A urea-formaldehyde adhesive was used in the proportion of 12% of the dry particle mass. The particleboards were pressed at a temperature of 130°C for 10 mins. The physical and mechanical properties analyzed were density, moisture content, thickness swelling, percentage of lignin and cellulose, modulus of resilience, modulus of elasticity and tensile strength parallel to the grain, accordingly to the standards NBR 14810 and CS 236-66 (1968). The particleboards were considered to be of medium density. The particle size significantly affected the static bending strength and tensile strength parallel to the grain. Ipê presented better results, demonstrating a potential for the production and use of particleboard made from this species. PMID:23836102

    2015-01-01

    Abstract The monotypic leucochrysine genus Nuvol was previously known from three specimens of Nuvol umbrosus Navás, collected in the Atlantic Forest region of Brazil. For many years these specimens have been missing, and the genus has remained without a modern description. Here, the species is redescribed based on two newly discovered specimens (females) from the Amazonian region. The female terminalia are relatively simple, except for the subgenitale, which is enlarged, folded into two sections, and heavily sclerotized. Unique aspects of the wing venation and the unusual pattern of banding on the wings support the retention of Nuvol as a valid genus within the Leucochrysini. There are differences between the Amazonian specimens studied here and the earlier descriptions based on specimens from the Atlantic Forest. These differences may indicate the presence of two distinct, geographically separated species within the genus. However, largely because we do not know the sexes of the earlier specimens, we are treating the differences discovered in the two female specimens as expressions of intraspecific variation.

    We describe the rheological, dielectric and elastic properties of a nematic liquid crystal gel created using an anthrylidene derivative of arjunolic acid, a chiral triterpenoid, obtained from the extracts of the wood of Terminalia arjuna. In this novel gel, having the electron-donor and acceptor components as minority constituents, the gelation and strengthening of charge-transfer complex (CTC) formation are seen to be occurring concomitantly. In addition to being mechanically strong with a large storage modulus, the gel with the maximized CTC exhibits Frank bend elastic constant values that approach nanonewton levels. The highlight of the study is the observation of 4–5 orders of magnitude increase in electrical conductivity for this gel, a value that is higher than even in the CT complexes of 2-d ordered columnar structures. A further important advantage of the present system over the columnar complex is that the high conductivity is seen for ac probing also, and owing to the nematic nature can be switched between its anisotropic limits. Some of these features are ascribed to a specific molecular packing architecture, which reduces the trapping of the charge carriers.

    A review of Pycnoglypta Thomson, 1858, including a redefinition of the genus, is given. Lectotype of Omalium luridum Gyllenhal, 1813 is designated. The seven species of the genus are placed into three species groups, including the new monotypic baicalica group. Dropephylla sibirica (Mäklin 1878) comb. nov. is transferred from the genus Pycnoglypta and redescribed; consequently, the Dropephylla sibirica species group, which had been diagnosed before by Gusarov within the genus Pycnoglypta, is reestablished in place of the Dropephylla puella species group erected by Jászay & Hlaváč based on erroneous identification of the nominate species. A new synonymy is established: Dropephylla linearis (Zetterstedt 1828) = D. puella (J. Sahlberg 1880) syn. nov. (=Phyllodrepa puella J. Sahlberg 1880). A key to all species of Pycnoglypta and all Siberian and Far Eastern Dropephylla species is provided. Both male and female genitalia and terminalia as well as other main morphological structures are figured anew; distributional data are provided and mapped for all the species discussed.

    Though arjunic acid, a triterpene isolated from Terminalia arjuna, was known to have antioxidant, antiinflammatory, and cytotoxic effects, its underlying antitumor mechanism still remains unclear so far. Thus, in the present study, the molecular antitumor mechanism of arjunic acid was examined in A549 and H460 non-small cell lung cancer (NSCLC) cells. Arjunic acid exerted cytotoxicity by 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyl tetrazolium bromide (MTT) assay and significantly increased sub-G1 population in A549 and H460 cells by cell cycle analysis. Consistently, arjunic acid cleaved poly (ADP-ribose) polymerase (PARP), activated Bax, and phosphorylation of c-Jun N-terminal kinases (JNK), and also attenuated the expression of pro-caspase-3 and Bcl-2 in A549 and H460 cells. Furthermore, arjunic acid upregulated the expression of endoplasmic reticulum (ER) stress proteins such as IRE1 α, ATF4, p-eIF2α, and C/EBP homologous protein (CHOP) in A549 and H460 cells. Conversely, CHOP depletion attenuated the increase of sub-G1 population by arjunic acid, and also JNK inhibitor SP600125 blocked the cytotoxicity and upregulation of IRE1 α and CHOP induced by arjunic acid in A549 and H460 cells. Overall, our findings suggest that arjunic acid induces apoptosis in NSCLC cells via JNK mediated ER stress pathway as a potent chemotherapeutic agent for NSCLC. PMID:26787261

    A new stick insect of the genus Orthomeria Kirby, 1904 (Phasmatodea, Aschiphasmatidae) is described from the Philippines. Orthomeria (Orthomeria) kangi sp. n. is readily distinguished from all other congeners by the distinctive blood red colouration of the costal region of the hind wings. Major features of the external morphology of adults, eggs, and first-instar nymphs are illustrated. Locomotory attachment pads are of the smooth type with irregular microgrooves on the contact surface. An unusual condition of male terminalia is the absence of tergal thorn pads on segment 10. The male clasping organs are represented by an elongated vomer terminating in a prominent spine, and by incurved cerci featuring a bilobed apex equipped with a sharp blade-like ridge. Intraspecific variation in body colouration and hind wing length occurs in females. The new species lives at 400-650 m elevation in the surroundings of the Sablang and Tuba regions, in the Benguet Province of Luzon island. Host plants include Ficus spp. (Moraceae), and Pipturus spp. and Leucosyke spp. (Urticaceae). Observations on the mating and defensive behaviour are presented. Orthomeria (Orthomeria) catadromus (Westwood, 1859) is recognised as a junior synonym of Orthomeria (Orthomeria) pandora (Westwood, 1859), syn. n. A lectotype is designated for both species. Finally, an updated identification key to the species of the subgenus Orthomeria is provided. PMID:27006604

    Present study was carried out regarding enzymatic assay for 5'-nucleotidase enzymes present in snake venom Naja naja karachiensis and to evaluate twenty eight medicinal plants as their antidotes. Elevated enzymatic activities i.e., 119, 183, 262 and 335 U/mL were observed in 10, 20, 30 and 40 µg of crude venom, respectively, in dose dependent manner. Among various plant extracts only two (Bauhinia vaiiegate L. and Citms linion (L.) Burm. f.) were found 94% effective at 160 µg to neutralize 112 U/mL activities (p 0.5) while reference standard was proved 93.2% useful at 80 pg to halt 111 U/mL activities. Cedrus deodara G. Don, Enicostemna hyssopifolium (Willd.) Verdoom, Terminalia arjuma Wight & Am. and Zingiber officinalis Rosc. (at 160 µg) were found ≥90% effective (0.5 ≥ p ≥ 0.1) while Citrulus colocynthis, Fogonia cretica L., Rhazya stticta Dcne and Stenolobiun stans (L.) D. Don (at 320 µg) were proved 90% effective (0.05 ≥ p ≥ 0.02). The remaining plant extracts were observed abortive (p ≥ 0.001) in neutralization of 5'-nucleotidases enzymatic actions. This study emphasizes further characterization of active plant extracts to further explore the antivenom influences of these herbal remedies against deleterious effects produced by 5'-nucleotidase enzymes after snake bite envenomation.

    HS-SPME was optimised using blank plant sample for analysis of organochlorine pesticides (OCPs) of varying polarities in selected medicinal plants obtained from northern part of Botswana, where OCPs such as DDT and endosulfan have been historically applied to control disease carrying vectors (mosquitos and tsetse fly). The optimised SPME parameters were used to isolate analytes from root samples of five medicinal plants obtained from Maun and Kasane, Botswana. The final analytes determination was done with a gas chromatograph equipped with GC-ECD and analyte was confirmed using electron ionisation mass spectrometer (GC-MS). Dieldrin was the only pesticide detected and confirmed with MS in the Terminalia sericea sample obtained from Kasane. The method was validated and the analyte recoveries ranged from 69.58 ± 7.20 to 113 ± 15.44%, with RSDs ranging from 1.19 to 17.97%. The method indicated good linearity (R2 > 0.9900) in the range of 2 to 100 ng g−1. The method also proved to be sensitive with low limits of detection (LODs) ranging from 0.48 ± 0.16 to 1.50 ± 0.50 ng g−1. It can be concluded that SPME was successfully utilized as a sampling and extraction tool for pesticides of diverse polarities in root samples of medicinal plants. PMID:27725893

    The bee subgenus Chilicola (Heteroediscelis) Toro & Moldenke, 1979 (Hymenoptera, Colletidae, Xeromelissinae) is revised. The subgenus is considered endemic to Chile and occurs across a broad range of habitats. Eight new species are described: Chilicola (Heteroediscelis) charizard Monckton, sp. n., Chilicola (Heteroediscelis) curvapeligrosa Monckton, sp. n., Chilicola (Heteroediscelis) guanicoe Monckton, sp. n., Chilicola (Heteroediscelis) katherinae Monckton, sp. n., Chilicola (Heteroediscelis) lickana Monckton, sp. n., Chilicola (Heteroediscelis) mayu Monckton, sp. n., Chilicola (Heteroediscelis) packeri Monckton, sp. n., and Chilicola (Heteroediscelis) randolphi Monckton, sp. n. One of the existing species, Chilicola (Heteroediscelis) valparaiso Toro & Moldenke, 1979, syn. n., is treated as a junior synonym of Chilicola (Heteroediscelis) mantagua Toro & Moldenke, 1979, and the nine remaining valid species are redescribed. Thoroughly illustrated keys to species for males and females are provided, along with habitus images, images of male terminalia, distribution maps for each species, and a map of relevant Chilean biogeographic regions. Results of phylogenetic analyses are presented, based upon 74 morphological characters and on CO1 barcode sequences, analyzed both separately and as a combined dataset. Monophyly of the subgenus is supported, and groupings within the subgenus are discussed in light of a biogeographic analysis of their species distributions (spatial analysis of vicariance), whereby divergence between taxa is found to occur primarily via north-south disjunctions.

    A facile rapid green eco-friendly method to synthesize gold nanoparticles (Au NPs) of tunable size using aqueous Terminalia arjuna fruit extracts has been demonstrated herein. Formation of Au NPs was confirmed by Surface Plasmon Resonance (SPR) study at 528 nm using UV-visible spectrophotometer. The time of reduction, size and morphological variations of Au NPs were studied with varying quantities of T. arjuna fruit aqueous extracts. Synthesized Au NPs were characterized using UV-visible spectroscopy, Fourier transformed infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), transmission electron microscopy (TEM) and Energy dispersive X-ray spectroscopy (EDAX). Polyphenols responsible for reduction of Au3+ to Au0 were identified using High Performance Liquid Chromatography (HPLC) as ascorbic acid, gallic acid and pyrogallol. The oxidized forms of polyphenols formed coordination with surface of Au NPs which protected their further growth and aggregation. We also propose a plausible mechanism how to tune size and shape of Au NPs by varying the quantity of extracts. Thus obtained Au NPs were stable for more than four months.

    The polyphenolic fractions of fruits: Terminalia catappa, Carissa carandas, Ziziphus nummularia; spice oilseeds: thymol, mustard, fenugreek and poppy seeds; and herb: green and black teas were analyzed for their total phenolics, flavonoids and antimicrobial potential. All fractions from fruits, except anthocyanin of C. carandas, displayed substantial antibacterial activity in accordance to their phenolic contents, the difference in activity being quite significant (p < 0.05), highest for T. catappa (minimum inhibitory concentration, MIC: 7.8-1000 microg/mL) and lowest for C. carandas (MIC: 62.5-1000 microg/mL). With few exceptions, both green and black teas' fractions inhibited the tested strains, however, green tea fractions (MIC: 15.63-125 microg/mL) were more active than black (MIC: 31.25-1000 microg/mL) and neutral were more active than their corresponding acidic fractions. Oil fractions of all oilseeds were found to be more active than their polyphenolic fractions, their antibacterial action decreased in the order thymol > mustard > fenugreek > poppy seeds (p < 0.05). Though the fruits used for the study are underutilized and have been emphasized for processed products, they may potentially be important to fight against pathogenic bacteria in view of their MICs. The teas and oilseeds, though a small part of total food intake, are more functional and active against the tested bacterial species and may find potential applications in therapeutics and food preservation.

    Abstract Species of the shore-fly genus Gymnoclasiopa Hendel from the New World are revised, including Gymnoclasiopa grecorum sp. n. (Alaska. Juneau: Gastineau Channel, Thane Road (S Juneau; 58°16.9'N, 134°22.4'W)) and Gymnoclasiopa matanuska sp. n. (Alaska. Matanuska-Susitna: Palmer (Matanuska River; 61°36.5'N, 149°04.1'W)). We also clarify the status of previously described species, including those now discovered to have Holarctic distributions and/or for which sexual dimorphism was not appreciated and the species was described twice, including Gymnoclasiopa montana (Cresson) as a syn. n. of Gymnoclasiopa bohemanni (Becker). Two species, Gymnoclasiopa bella (Mathis), comb. n., and Gymnoclasiopa chiapas (Mathis), comb. n., are transferred from Ditrichophora to Gymnoclasiopa, and Gymnoclasiopa cana Cresson stat. rev. and Ditrichophora canifrons Cresson, stat. rev. are returned to Ditrichophora, the genus in which Cresson originally described them. A neotype is designated for Gymnoclasiopa tacoma to stabilize the nomenclature of this species. The two excluded species, Ditrichophora cana and Ditrichophora canifrons, are diagnosed and distributional data are also provided. For all known New World species of Gymnoclasiopa, structures of the male terminalia are described for the first time and are fully illustrated. Detailed locality data and distribution maps are also included. To provide context and also to facilitate identification, diagnoses are included for the tribe Discocerinini and genus in addition to a key to the genera and species occurring in the New World.

    Goniglossum Rondani, hitherto a monobasic genus, is reinstated from synonymy under Carpomya Costa. A second species, Goniglossum liat n. sp., is described nearly two centuries after the description of the first species and 160 years after the description of Goniglossum. G. liat is described from Israel (also known from Turkey) and compared with G. wiedemanni (Meigen), an essentially European species, which is the type-species of Goniglossum and the only other known congener. The two species differ in details of the mesonotal and pleural color pattern (e.g., tip of scutellum with three small black spots in G. wiedemanni, whereas with one large spot in G. liat), structure of the male and female terminalia (e.g., the aculeus of G. wiedemanni is distinctly narrower apically than that of G. liat, and its tip has significantly fewer teeth), and host plant associations (Bryonia alba L. and B. dioica Jacq. are hosts of G. wiedemanni, whereas Bryonia cretica L. and B. syriaca Boiss. are hosts of G. liat). Myiopardalis Bezzi is also reinstated from synonymy under Carpomya. C. tica Norrbom, originally described in Carpomya, is transferred to Norrbomella, new genus, as its type and only included species.

    Respiratory ailments are major human killers, especially in developing countries. Tuberculosis (TB) is an infectious disease causing a threat to human healthcare. Many South African plants are used in the traditional treatment of TB and related symptoms, but there has not been a sufficient focus on evaluating their antimicrobial properties. The aim of this study was to evaluate the antimicrobial properties of plants used traditionally to treat TB and related symptoms against microorganisms (Klebsiella pneumoniae, Staphylococcus aureus, and Mycobacterium aurum A+) associated with respiratory infections using the microdilution assay. Ten plants were selected based on a survey of available literature of medicinal plants used in South Africa for the treatment of TB and related symptoms. The petroleum ether, dichloromethane, 80% ethanol, and water extracts of the selected plants were evaluated for antibacterial activity. Out of 68 extracts tested from different parts of the 10 plant species, 17 showed good antimicrobial activities against at least one or more of the microbial strains tested, with minimum inhibitory concentration ranging from 0.195 to 12.5 mg/mL. The good antimicrobial properties of Abrus precatorius, Terminalia phanerophlebia, Indigofera arrecta, and Pentanisia prunelloides authenticate their traditional use in the treatment of respiratory diseases. Thus, further pharmacological and phytochemical analysis is required. PMID:23533527

    Abstract The genus Reichardtiolus Kryzhanovskij, 1959 is revised herein. It now contains five species: R. duriculus (Reitter, 1904) from middle Asia (with a doubtful female specimen from western China that is here tentatively assigned to this species), R. pavlovskii Kryzhanovskij, 1959 from Turkmenistan, R. sphingis (Peyerimhoff, 1936), comb. n. (transferred from Saprinus Erichson, 1834) from Egypt and Jordan, R. perses sp. n. from Iran and R. aldhaferi sp. n. from Saudi Arabia. Except for R. pavlovskii, which is a rather distinct species known only from two females, the remaining species are allopatric, very similar externally and are best separated from each other by their male terminalia. R. pavlovskii is kept in Reichardtiolus only tentatively, pending the examination of more specimens, and especially its male genitalia. R. duriculus and R. pavlovskii are re-described, while R. perses sp. n., R. aldhaferi sp. n. and R. sphingis comb. n. are provided with diagnostic descriptions because of their overall similarity with R. duriculus. Morphological differences of all species are illustrated using SEM micrographs. Male genitalia of R. duriculus, R. sphingis comb. n., R. perses sp. n. and R. aldhaferi sp. n. are illustrated and a key to the species is given. R. duriculus is newly recorded from Tajikistan.

    Terminalia arjuna (T. arjuna) bark extract is used to reduce Cu(2+)→Cu(0) under microwave irradiation. The formation of copper nanoparticles (CuNPs) is monitored by recording the UV-Vis absorption spectra for surface plasmon resonance (SPR) peak, ~535 nm. The intensity of SPR increased linearly with increasing temperature of the reaction mixture. The formation mechanism of CuNPs is supported by the observed marginal decrease in pH and an increase in solution potential (E) of the reaction mixture. X-ray diffraction (XRD) pattern of the CuNPs agrees with the reported data for Cu metal and the crystallite size is ~23 nm. Fourier transform infrared spectroscopy (FT-IR) and solid-state (13)C NMR shows the presence of plant residues on the CuNPs, i.e., in situ bio-capping is possible by this method. Thermo gravimetric (TG) analysis shows the thermal degradation of plant residue and the conversion of Cu to CuO. Field emission electron microscopic (FESEM) image shows uniform spherical particles obtained here. Elemental analysis by energy dispersive X-ray (EDX) analysis confirms the presence of Cu alone, as expected. The in vitro antimicrobial activity is found to be effective for CuNPs dried at RT when compared to CuNPs dried at 70 °C. In addition, CuNPs shows very good antioxidant property.

    Avai'o'vuna Swamp, a small coastal wetland in Vava'u, Kingdom of Tonga, produced a 4500-year pollen and sediment record. Results are: (1) a mid-Holocene sea level highstand is confirmed for Tonga between about 4500 and 2600 14C yr B.P.; marine clay contains pollen from mangroves ( Rhizophora mangle), coastal forest trees ( Barringtonia asiatica and Cocos nucifera), and rainforest trees ( Alphitonia, Rhus, Hedycarya and Calophyllum). (2) Microscopic charcoal first appeared at 2600 14C yr B.P., coincident with the arrival of Polynesians. (3) Cocos, Pandanus, Excoecaria, Macaranga, and Elaeocarpaceae pollen reflects the establishment of a mixed coastal-lowland rainforest in the last 2500 years. (4) The loss of Hedycarya, Elaeocarpus, Calophyllum, and Guettarda and the reduction of Terminalia and taxa in the Papilionaceae family by about 1000 years ago may be due to habitat destruction and the loss of dispersal capabilities of some species through the extinction of the two largest pigeons in Tonga.

    Abstract A new stick insect of the genus Orthomeria Kirby, 1904 (Phasmatodea, Aschiphasmatidae) is described from the Philippines. Orthomeria (Orthomeria) kangi sp. n. is readily distinguished from all other congeners by the distinctive blood red colouration of the costal region of the hind wings. Major features of the external morphology of adults, eggs, and first-instar nymphs are illustrated. Locomotory attachment pads are of the smooth type with irregular microgrooves on the contact surface. An unusual condition of male terminalia is the absence of tergal thorn pads on segment 10. The male clasping organs are represented by an elongated vomer terminating in a prominent spine, and by incurved cerci featuring a bilobed apex equipped with a sharp blade-like ridge. Intraspecific variation in body colouration and hind wing length occurs in females. The new species lives at 400-650 m elevation in the surroundings of the Sablang and Tuba regions, in the Benguet Province of Luzon island. Host plants include Ficus spp. (Moraceae), and Pipturus spp. and Leucosyke spp. (Urticaceae). Observations on the mating and defensive behaviour are presented. Orthomeria (Orthomeria) catadromus (Westwood, 1859) is recognised as a junior synonym of Orthomeria (Orthomeria) pandora (Westwood, 1859), syn. n. A lectotype is designated for both species. Finally, an updated identification key to the species of the subgenus Orthomeria is provided. PMID:27006604

    Using compressed air, we excavated individual trees and shrubs and mapped their coarse root systems on a three-dimensional grid system up to 1.5 m depth. We excavated four woody savanna species at three sites spanning a climate gradient on the Kalahari Transect in southern Africa. Overall, species was more important than site in determining both large-scale and small-scale root system structure. The species excavated fell into two groups that coexisted across the climate gradient. Acacia mellifera and Terminalia sericea had straight roots in a laterally-extensive and relatively shallow system. Boscia albitrunca and Ochna pulchra had sinuous roots that were mostly concentrated beneath the canopy and were more prevalent in deep than near-surface soil layers, departing from the conventional model of decreasing root abundance with depth. The shallow-rooted species had small taproots, though it is unlikely that they reached the water table. Deep- and shallow-rootedness appear to correlate with other characteristics such as growth form (tree or shrub) and drought deciduousness. Acacia mellifera Boscia albitrunca

    In an ethnopharmacological survey, extracts of the six East African medicinal plants Entada abyssinica (stem bark), Terminalia spinosa (young branches), Harrisonia abyssinica (roots), Ximenia caffra (roots), Azadirachta indica (stem bark and leaves), and Spilanthes mauritiana (roots and flowers) were tested against 105 strains of bacteria from seven genera (Staphylococcus, Enterococcus, Pseudomonas, Escherichia, Klebsiella, Salmonella, Mycobacterium). The minimum inhibitory concentration reached by 50% (MIC50%) and 90% (MIC90) of the strains for the extracts of E. abyssinica, T. spinosa, X. caffra, and A. indica (stem bark) ranged from 0.13-8 mg/ml and from 0.5 to > 8 mg/ml, respectively. Their minimum bactericidal concentration by 50% (MBC50%) and MBC90% were all between 0.5 and > 8 mg/ml. H. abyssinica, A. indica (leaves), and S. mauritiana (roots and flowers) had MIC and MBC values > or = 8 mg/ml. Mycobacteria were not inhibited at extract concentrations of 0.5-2 mg/ml. It is concluded that plant extracts with low MIC and MBC values may serve as sources for compounds with therapeutic potency. PMID:9533435

    The trapping of lipid-laden macrophages in the arterial intima is a critical but reversible step in atherogenesis. However, information about possible treatments for this condition is lacking. Here, we hypothesized that combining the polyphenol-rich fractions (PHC) of commonly consumed spices (Allium sativum L (Liliaceae), Zingiber officinale R (Zingiberaceae), Curcuma longa L (Zingiberaceae)) and herbs (Terminalia arjuna (R) W & A (Combretaceae) and Cyperus rotundus L (Cyperaceae)) prevents foam cell formation and atherogenesis. Using an in vitro foam cell formation assay, we found that PHC significantly inhibited lipid-laden macrophage foam cell formation compared to the depleted polyphenol fraction of PHC (F-PHC). We further observed that PHC attenuated the LDL and LPS induced CD36, p-FAK and PPAR-γ protein expression in macrophages and increased their migration. NK-κB-DNA interaction, TNF-α, ROS generation, and MMP9 and MMP2 protein expression were suppressed in PHC-treated macrophages. The anti-atherosclerotic activity of PHC was investigated in a high fat- and cholesterol-fed rabbit model. The inhibition of foam cell deposition within the aortic intima and atheroma formation confirmed the atheroprotective activity of PHC. Therefore, we conclude that the armoury of polyphenols in PHC attenuates the CD36 signalling cascade-mediated foam cell formation, enhances the migration of these cells and prevents atherogenesis.

The eco-friendly synthesized NPs were characterized by UV-Vis-DRS, ATR-FT-IR, PL, XRD, Raman, SEM with EDX and TEM analysis. The synthesized NPs were investigation for dye sensitized solar cell applications. UV-Vis-Diffused Reflectance Spectra clearly showed that the expected TiO2 inter band absorption below 306 nm, incorporation of gold shows surface plasma resonant (SPR) near 555 nm and platinum incorporated TiO2 NPs shows absorbance at 460 nm. The energy conversion efficiency for Au doped TiO2 NPs when compared to pure and Pt doped TiO2 NPs. In addition to that, Au noble metal present TiO2 matrix and an improve open-circuit voltage (Voc) of DSSC. Synthesized NPs was evaluated into antibacterial and antifungal activities by disk diffusion method. It is observed that NPs have not shown any activities in all tested bacterial and fungal strains. In this eco-friendly synthesis method to provide non toxic and environmental friendly nanomaterials can be used for solar energy device application.

    Bombylisoma Rondani is a genus of bee flies belonging to the subfamily Bombyliinae (Hull, 1973). It is easily identified by the following characters: Head usually as broad as thorax; hind-margin of eyes indented; wings often small, narrowed at base with at least alula reduced; hind femora often without macrochaetae; body usually more elongate even narrow conical or cylindrical, macrochaetae usually weak often hair-like especially those posterior to the wings; cell r5 open, pulvilli well-developed; male terminalia with gonocoxite without prominent crest; parameral sheath, bearing paired horn-like outgrowths (Greathead & Evenhuis, 2001). Bombylisoma includes two known species from the Oriental Region: B. ghorpadei Kapoor & Agarwal, 1979 and B. resplendens Brunetti, 1909 (Evenhuis & Greathead, 2015). No species has previously been reported from China. Recently, one specimen of Bombylisoma collected from Yunnan was found in the Bernice Pauahi Bishop Museum. In the present paper this species, B. resplendens Brunetti, is redescribed and this represents the first record of the genus from China. A key to the genera of the Bombyliinae from China is presented. PMID:27470722

    Nonstructural protein 1 (NS1) of the highly pathogenic avian influenza virus (H5N1) contains a conserved RNA binding domain (RBD) that inhibits antiviral functions of host-innate immune response. Dimerization of NS1 forms a central groove and binds to double stranded (ds) RNA. This region might serve as a potential drug target. In this study, three dimensional structure model of NS1 RBD protein was constructed and virtual screening was performed to identify lead compounds that bound within and around the central groove. The virtual screening showed that 5 compounds bound within the central groove with binding energy ranging between -16.05 and -17.36 Kcal/mol. Two commercially available compounds, estradiol and veratridine, were selected for using in an in vitro screening assay. The results showed that neither of the compounds could inhibit the association between dsRNA and NS1 RBD protein. In addition, 34 herbal extracts were examined for their inhibitory effects. Five of them were able to inhibit association between NS1 RBD and dsRNA in electrophoresis mobility shift assay. Four herbs, Terminalia belirica, Salacia chinensis, Zingiber montanum and Peltophorum pterocarpum, could reduce > 50% of infectivity of H5N1 in a cell-based assay, and it is worth further studying their potential use as source of antiviral drugs.

    Abstract The bee subgenus Chilicola (Heteroediscelis) Toro & Moldenke, 1979 (Hymenoptera, Colletidae, Xeromelissinae) is revised. The subgenus is considered endemic to Chile and occurs across a broad range of habitats. Eight new species are described: Chilicola (Heteroediscelis) charizard Monckton, sp. n., Chilicola (Heteroediscelis) curvapeligrosa Monckton, sp. n., Chilicola (Heteroediscelis) guanicoe Monckton, sp. n., Chilicola (Heteroediscelis) katherinae Monckton, sp. n., Chilicola (Heteroediscelis) lickana Monckton, sp. n., Chilicola (Heteroediscelis) mayu Monckton, sp. n., Chilicola (Heteroediscelis) packeri Monckton, sp. n., and Chilicola (Heteroediscelis) randolphi Monckton, sp. n. One of the existing species, Chilicola (Heteroediscelis) valparaiso Toro & Moldenke, 1979, syn. n., is treated as a junior synonym of Chilicola (Heteroediscelis) mantagua Toro & Moldenke, 1979, and the nine remaining valid species are redescribed. Thoroughly illustrated keys to species for males and females are provided, along with habitus images, images of male terminalia, distribution maps for each species, and a map of relevant Chilean biogeographic regions. Results of phylogenetic analyses are presented, based upon 74 morphological characters and on CO1 barcode sequences, analyzed both separately and as a combined dataset. Monophyly of the subgenus is supported, and groupings within the subgenus are discussed in light of a biogeographic analysis of their species distributions (spatial analysis of vicariance), whereby divergence between taxa is found to occur primarily via north-south disjunctions.

    A new genus and species of stick insect is described and figured from Mount Halcon, on the Philippine island of Mindoro. Conlephasma enigma gen. et sp. n. is a stout, flightless, and apparently ground-dwelling species with vivid integumental colors. When disturbed, specimens spray a defensive secretion from the prothoracic exocrine glands. The systematic position of Conlephasma within Euphasmatodea is unclear. The elongated galealobulus and the trichome area located laterally in the galea, represent unusual apomorphic characters of the maxilla that could indicate affinities with Necrosciinae or Pseudophasmatinae. All tibiae exhibit the anareolate condition. Euplantulae are of two types: those of tarsomeres I-IV feature a nubby microstructure, whilst the one on the ventral side of the pretarsus is smooth. Males are characterized by the presence of a well-developed vomer on the tenth abdominal segment. A distinctive and apomorphic trait of female terminalia is represented by the elongated tenth abdominal tergum. Conlephasma can represent an interesting taxon for studies on the evolution of the stick and leaf insects.

    Amyloid-beta peptide (Aβ) is implicated in the pathogenesis of Alzheimer's disease (AD), a neurodegenerative disorder. This study was designed to determine the effect of four medicinal plants used to treat neurodegenerative diseases on Aβ-induced cell death. Cytotoxicity of the ethanol extracts of the plants was determined against SH-SY5Y (human neuroblastoma) cells which were untreated, as well as toxically induced with Aβ, using the MTT and neutral red uptake assays. Cell viability was reduced to 16% when exposed to 20 µM Aβ25-35 for 72 h. The methanol extract of the roots of Ziziphus mucronata Willd., Lannea schweinfurthii (Engl.) Engl. and Terminalia sericea Burch. ex DC., were the least toxic to the SH-SY5Ycells at the highest concentration tested (100 µg/ml). All four plants tested were observed to reduce the effects of Aβ-induced neuronal cell death, indicating that they may contain compounds which may be relevant in the prevention of AD progression.

    The objective of this study as to determine the anti-atherogenic effect of cardiproa poly herbal cardiotonic which primarily contains the standardized extracts of Terminalia arjuna, Ocimum sanctum, Boerhaavia diffusa, Emblica officinalis and withania somnifera. For this purpose, 24 adult wistar albino rats were equally divided into 4 groups. Group I acted as control, Group 2 received individually cholesterol 100mg/kg dissolved in vegetable oil (4mg/ml) orally daily for 30 days. Group 3 received cardiPro 25 mg/kg body weight individually orally dissolved in distilled water daily for 30 days in combination with cholesterol as in group2, wile group 4 instead received Cardipro @ 50mg/kg body weight along with cholesterol. It was found that plasma total lipid, cholesterol, low density lipids, very low density lipids, triglycerides as well as aortic cholesterol contents were higher in cholesterol fed rats in comparison to health controls. Treatment with Cardipro significant; reduced the levels of these blood lipid profiles suggesting anti-atherogenic action of cardipro in rats. This was further strengthened b histopathological examination of Aorta in which the cholesterol fed rats treated with Cardipro @ 50% mg/kg body weight revealed only occasional presence of fat in the medial coat and intact elastic fibres in contrest to marked elevations and depressions I the tunica intima associated muscles of medical coat and disruption of elastic fibres in only cholesterol fed rats.

    Present study was carried out regarding enzymatic assay for 5'-nucleotidase enzymes present in snake venom Naja naja karachiensis and to evaluate twenty eight medicinal plants as their antidotes. Elevated enzymatic activities i.e., 119, 183, 262 and 335 U/mL were observed in 10, 20, 30 and 40 µg of crude venom, respectively, in dose dependent manner. Among various plant extracts only two (Bauhinia vaiiegate L. and Citms linion (L.) Burm. f.) were found 94% effective at 160 µg to neutralize 112 U/mL activities (p 0.5) while reference standard was proved 93.2% useful at 80 pg to halt 111 U/mL activities. Cedrus deodara G. Don, Enicostemna hyssopifolium (Willd.) Verdoom, Terminalia arjuma Wight & Am. and Zingiber officinalis Rosc. (at 160 µg) were found ≥90% effective (0.5 ≥ p ≥ 0.1) while Citrulus colocynthis, Fogonia cretica L., Rhazya stticta Dcne and Stenolobiun stans (L.) D. Don (at 320 µg) were proved 90% effective (0.05 ≥ p ≥ 0.02). The remaining plant extracts were observed abortive (p ≥ 0.001) in neutralization of 5'-nucleotidases enzymatic actions. This study emphasizes further characterization of active plant extracts to further explore the antivenom influences of these herbal remedies against deleterious effects produced by 5'-nucleotidase enzymes after snake bite envenomation.

    Azadirachta indica, Emblica officinalis, Syzygium cumini and Terminalia bellirica are common in Indian system of traditional medicine for the prevention of diabetes and its complications. The aim of the present study was to comprehensively and comparatively investigate the antiglycation potential of these plant extracts at multiple stages and their possible protective effect against glycated albumin mediated toxicity to erythrocytes. Antiglycation activities of these plant extracts was measured by co-incubation of plant extract with bovine serum albumin-fructose glycation model. The multistage glycation markers- fructosamines (early stage), protein carbonyls (intermediate stage) and AGEs (late stage) are investigated along with measurement of thiols and β aggregation of albumin using amyloid-specific dyes-Congo red and Th T. Protection of erythrocytes from glycated albumin induced toxicity by these plant extracts was assessed by measuring erythrocytes hemolysis, lipid peroxidation, reduced glutathione and intracellular antioxidant capacity. Total phenolics, reducing power and antioxidant activities of the plant extracts were also measured. In vitro glycation assays showed that plant extracts exerted site specific inhibitory effects at multiple stages, with T. bellirica showing maximum attenuation. In erythrocytes, along with the retardation of glycated albumin induced hemolysis and lipid-peroxidation, T. bellirica considerably maintained cellular antioxidant potential. Significant positive correlations were observed between erythrocyte protection parameters with total phenolics. These plant extracts especially T. bellirica prevents glycation induced albumin modifications and subsequent toxicity to erythrocytes which might offer additional protection against diabetic vascular complications.

    Goniglossum Rondani, hitherto a monobasic genus, is reinstated from synonymy under Carpomya Costa. A second species, Goniglossum liat n. sp., is described nearly two centuries after the description of the first species and 160 years after the description of Goniglossum. G. liat is described from Israel (also known from Turkey) and compared with G. wiedemanni (Meigen), an essentially European species, which is the type-species of Goniglossum and the only other known congener. The two species differ in details of the mesonotal and pleural color pattern (e.g., tip of scutellum with three small black spots in G. wiedemanni, whereas with one large spot in G. liat), structure of the male and female terminalia (e.g., the aculeus of G. wiedemanni is distinctly narrower apically than that of G. liat, and its tip has significantly fewer teeth), and host plant associations (Bryonia alba L. and B. dioica Jacq. are hosts of G. wiedemanni, whereas Bryonia cretica L. and B. syriaca Boiss. are hosts of G. liat). Myiopardalis Bezzi is also reinstated from synonymy under Carpomya. C. tica Norrbom, originally described in Carpomya, is transferred to Norrbomella, new genus, as its type and only included species.

    Recently dyes derived from natural sources have emerged as important alternatives to synthetic dyes. A study was initiated in the year 2000 at the RRL (CSIR), Jorhat to extract dyes from parts of five different plant species indigenous to northeastern India. The colour components responsible for dyeing were isolated and their chemical constituents were established based on chemical and spectroscopic investigations. The principal colour components from the species Morinda angustifolia Roxb., Rubia cordifolia Linn. and Tectona grandis Linn. were found to contain mainly anthraquinone moieties in their molecules. Those from the species Mimusops elengi Linn. and Terminalia arjuna (Roxb.) Wight & Arn. contained flavonoid moieties in their molecules. The absorption of dye (%) on fibres increased with increasing concentrations of dye in the dye-bath. Maximum absorption of dyes on fibres was obtained at 3% concentration of dyes obtained from R. cordfolia (35.350%), M. angustifolia (31.580%) and T. grandis (25.888%) and at 4% concentration of the dyes from M. elengi (31.917%) and T. arjuna (12.246%). The K/S values were found to increase with the increase in concentration of mordants. The colour co-ordinates of dyed samples were found to lie in the yellow-red quadrant of the colour space diagram. The dyes obtained from the native plants may be alternative sources to synthetic dyes for the dyeing of natural silk and cotton. PMID:15474939

    A bioreductive capacity of a plant, Terminalia arjuna leaf extract, was utilized for preparation of selenium nanoparticles. The leaf extract worked as good capping as well as stabilizing agent and facilitated the formation of stable colloidal nanoparticles. Resulting nanoparticles were characterized using UV-Vis spectrophotometer, transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDAX), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction analysis (XRD), respectively. The colloidal solution showed the absorption maximum at 390 nm while TEM and selected area electron diffraction (SAED) indicated the formation of polydispersed, crystalline selenium nanoparticles of size raging from 10 to 80 nm. FT-IR analysis suggested the involvement of O-H, N-H, C=O, and C-O functional group of the leaf extract in particle formation while EDAX analysis indicated the presence of selenium in synthesized nanoparticles. The effect of nanoparticles on human lymphocytes treated with arsenite, As(III), has been studied. Studies on cell viability using MTT assay and DNA damage using comet assay revealed that synthesized selenium nanoparticles showed protective effect against As(III)-induced cell death and DNA damage. Chronic ingestion of arsenic infested groundwater, and prevalence of arsenicosis is a serious public health issue. The synthesized benign nanoselenium can be a promising agent to check the chronic toxicity caused due to arsenic exposure.

    An intensive search for the larval habitats of Lutzomyia longipalpis (Lutz & Neiva) was conducted from November 1992 to October 1993 at a small rural community in Colombia where American visceral leishmaniasis is endemic. Emergence traps constructed from polyvinyl chloride pipes were used to sample a variety of soil microhabitats that included edge areas of covered pigpens, cattle corrals, the base of trees, and leaf litter at sites within 40 m of a house, rocks in fields located between 50 and 500 m from houses, and sites within a patch of secondary forest (rocks, base of palm trees, and leaf litter). The teneral status of the sand flies captured in the emergence traps was confirmed by laboratory studies that determined the rate of terminalia rotation in male L. longipalpis and the rate of cuticular growth layer formation of the thoracic phragma in both sexes of this species. A total of 58 teneral sand flies was captured during the study period (49 wk). Fifteen specimens were L. longipalpis; of these 11 (5 sand flies per square meter) were captured near pigpens, 3 (1.4 sand flies per square meter) were captured near rock resting sites, and 1 (1.6 sand flies per square meter) was collected at the base of a tree. The remainder of the sand flies were either L. trinidadensis (Newstead) or L. cayennensis (Flock & Abonnenc). Our results indicate that L. longipalpis larvae were dispersed widely in sites near houses, rather than concentrated in a few optimal microhabitats.

    The antiatherogenic effect of a herbal formulation, Caps HT2, was evaluated as antioxidant, anticoagulant, platelet antiaggregatory, lipoprotein lipase releasing, anti-inflammatory and hypolipidaemic activity in rats. The formulation contained the methanolic extracts of selected parts of plants, Commiphora mukul, Allium sativum, Plumbago indica, Semecarpus anacardium, Hemidesmus indicus, Terminalia arjuna, Tinospora cordifolia, Withania somnifera and Ocimum sanctum. The formulation, Caps HT2 was found to scavenge superoxide and hydroxyl radicals; the IC50 required being 55.0 and 610.0 microg/ml respectively. The lipid peroxidation was found inhibited (50%) by 48.5 microg/ml of Caps HT2. The intravenous administration of the formulation (5 mg/kg) delayed the plasma recalcification time in rabbits and enhanced the release of lipoprotein lipase enzyme significantly (p < 0.001). The formulation also inhibited ADP induced platelet aggregation in vitro, which was comparable to commercial heparin. The anti-inflammatory action of the formulation was significant (p < 0.001) with acute and chronic inflammations induced by carrageenan and formalin respectively in rats. The hypolipidaemic effect of Caps HT2 was significant (p < 0.001) with the administration of the formulation, in diet-induced hyperlipidaemia of rats for a period of 30 days. Oral administration of the formulation, Caps HT2 (100, 200, 300 and 400 mg/kg) significantly raised HDL cholesterol levels. The atherogenic index and the reduction in body weight were significant indicating the effectiveness against hyperlipidaemia and obesity. All these results revealed the therapeutic potential of Caps HT2 against vascular intimal damage and atherogenesis leading to various types of cardiovascular problems. PMID:13678230

    The silkworm is the larva or caterpillar of the domesticated silkmoth, Bombyx mori and being a primary producer of silk is an economically important insect. These days the silk is emerging as a resource for solving a broad range of biological problems. The silk (Abresham) is popularly known as Abresham muqriz (muqriz means cut) in Unani medicine. Its cocoons are extensively used as an ingredient of various Unani formulations like Khameer-E- Abresham Sada, Khameere Abresham Hakeem Arshad Wala, Khameere Abresham Ood Mastagi Wala etc. and are used to treat many cardiac and nervous disorders. The hypolipidemic activity of this drug, along with Nepata Hindostana (Badranjboya) and Terminalia Arjuna (Arjan) has been documented. But action of extract of Bombyx mori cocoons as a single drug is not documented. That's why; it was decided to study its effect on hyperlipidemia and atherosclerosis. The Male New Zealand White rabbits all of 1.5kgs were selected for the study. After stabilization period (2 weeks) the rabbits were divided into 3 groups (Group I - Control, Group II Lesion Control and Group III treated with extract of Bombyx mori silk cocoon). Hyperlipidemia and atherosclerosis were induced with 1% cholesterol diet. After induction of hyperlipidemia and atherosclerosis for twelve weeks, Group III rabbits were treated with Bombyx mori for 6 weeks (45 days). A significant decrease in hyperlipidemia was seen within 4 weeks of treatment. Histopathologically, the atherosclerotic plaques showed reduction in size. The third group showed a significant increase in the body weight and also an increase in the HDL cholesterol levels. The study concludes that extract of Bombyx mori cocoons has a significant effect on hypercholesterolemia and atherosclerosis probably because of its antioxidant and hypolipidemic effect.

    Context Ischemic-reperfusion injury is accompanied by a decreased contractility of the myocardium. Positive-inotropic agents have proven useful for treating this condition but may exert serious side-effects. Objective In this study, aqueous preparations from Abelmoschus esculentus L. Moench (Malvaceae), Annona muricata L. (Annonaceae), Bixa orellana L. (Bixaceae), Cecropia peltata L. (Moraceae), Erythrina fusca Lour. (Fabaceae), Psidium guajava L. (Myrtaceae) and Terminalia catappa L. (Combretaceae) were evaluated for their ability to improve the decreased contractility of isolated guinea pig atria after hypoxic stress. Materials and methods Guinea pig atria isolated in Ringer-Locke buffer gassed with 100% O2 at 30 °C were exposed for 5 min to hypoxia, then allowed to recover in oxygenated buffer alone or containing a single plant extract (0.001-1 mg/mL). The contractility (g/s) and beating frequency (beats/min), as well as troponin C contents of the bathing solution (ng/mL), were determined and expressed as means ± SDs. Results The extracts of A. muricata, B. orellana, C. peltata and T. catappa caused an increase in the contractility compared to untreated atria of 340 ± 102%, 151 ± 13%, 141 ± 14% and 238 ± 44%, respectively. However, the latter two preparations increased the troponin C contents of the bathing solution to 36 ± 11 and 69 ± 33, compared to the value of 11 ± 3 ng/mL found with untreated atria. Conclusions Preparations from A. muricata and B. orellana may possess positive-inotropic properties which may improve the contractility of the post-hypoxic myocardium. Studies to assess their usefulness in ischemic-reperfusion injury are warranted.

    The majority of the plant materials used in herbal medicine is procured from the markets in the form of dried or powdered plant parts. It is essential to use authentic plant materials to derive the benefits of herbal medicine. However, establishing the identity of these plant materials by conventional taxonomy is extremely difficult. Here we report a case study in which the species identification of the market samples of Sida cordifolia was done by DNA barcoding. As a prelude to species identification by DNA barcoding, 13 species of Sida were collected, and a reference DNA barcode library was developed using rbcL, matK, psbA-trnH and ITS2 markers. Based on the intra-species and inter-species divergence observed, psbA-trnH and ITS2 were found to be the best two-marker combination for species identification of the market samples. The study showed that none of the market samples belonged to the authentic species, S. cordifolia. Seventy-six per cent of the market samples belonged to other species of Sida. The predominant one was Sida acuta (36%) followed by S. spinosa (20%), S. alnifolia (12%), S. scabrida (4%) and S. ravii (4%). Such substitutions may not only fail to give the expected therapeutic effect, but may also give undesirable effects as in case of S. acuta which contains a 6-fold higher amount of ephedrine compared to the roots of S. cordifolia. The remaining 24% of the samples were from other genera such as Abutilon sp. (8%), Ixonanthes sp., Terminalia sp., Fagonia sp., and Tephrosia sp. (4% each). This observation is in contrast to the belief that medicinal plants are generally substituted or adulterated with closely related species. The current study strongly suggests that the raw drug market samples of herbal medicines need to be properly authenticated before use, and DNA barcoding has been found to be suitable for this purpose.

    Human African trypanosomiasis is a neglected tropical disease with complex clinical presentation, diagnosis, and difficult treatment. The available drugs for the treatment of trypanosomiasis are old, expensive, and less effective, associated with severe adverse reactions and face the problem of drug resistance. This situation underlines the urgent need for the development of new, effective, cheap, and safe drugs for the treatment of trypanosomiasis. The search for new antitrypanosomal agents in this study is based on ethnomedicine. In vitro antitrypanosomal activity of 36 plant extracts from 10 plant species from Nigerian ethnomedicine was evaluated against bloodstream forms of Trypanosoma brucei rhodesiense STIB 900. Cytotoxic activity was determined against mammalian L6 cells. Alamar blue assay was used to measure the endpoint of both antitrypanosomal and toxicity assays. The ethyl acetate extract of leaves of Ocimum gratissimum Linn. (Labiatae) showed the highest antitrypanosomal activity (IC(50) of 2.08 ± 0.01 μg/ml) and a high selective index of 29. Furthermore, the hexane, ethyl acetate, or methanol extracts of Trema orientalis (L.) Blume (Ulmaceae), Pericopsis laxiflora (Benth. ex Baker) Meeuwen, Jatropha curcas Linn. (Euphorbiaceae), Terminalia catappa Linn. (Combretaceae), and Vitex doniana Sweet (Verbenaceae) displayed remarkable antitrypanosomal activity (IC(50) 2.1-17.2 μg/ml) with high selectivity indices (20-80) for trypanosomes. The antitrypanosomal activity of T. catappa and T. orientalis against T. brucei rhodesiense (STIB 900) is being reported for the first time in Nigerian ethnomedicine, and these plants could be a potential source of antitrypanosomal agents.

    The use of medicinal plants for the treatment of diseases including malaria is commonplace in Ghanaian traditional medicine, though the therapeutic claims for most plants remain unvalidated. Antiplasmodial activity of the aqueous extracts and successively obtained petroleum ether, ethyl acetate and methanol fractions of the whole Phyllanthus fraternus plant, the leaves of Tectona grandis, Terminalia ivorensis and Bambusa vulgaris, and roots of Senna siamea were studied against Plasmodium falciparum chloroquine-sensitive 3D7 and chloroquine-resistant W2 strains. The aqueous extracts were assessed against human umbilical vein endothelial cells (HUVECs) for cytotoxicity, and the organic solvent fractions against human O(+) erythrocytes for haemolytic effect. Both extracts and fractions demonstrated antiplasmodial activity to varied extents. The aqueous extract of T. ivorensis was the most active (3D7, IC50 0.64 ± 0.14; and W2, IC50 10.52 ± 3.55 μg/mL), and together with P. fraternus displayed cytotoxicity (CC50 6.25 ± 0.40 and 31.11 ± 3.31 μg/mL, respectively). The aqueous extracts were generally selective for 3D7 strain of P. falciparum (selectivity indexes (SIs) ≥3.48) but only that of S. siamea was selective for the W2 strain (SI > 2.1). The organic solvent fractions also displayed antiplasmodial activity with the methanol fractions of P. fraternus and T. grandis, and the fractions of B. vulgaris showing activity with IC50 below 1 μg/mL against P. falciparum 3D7 strain; some fractions showed haemolytic effect but with low to high selectivity indexes (SI ≥ 4). The results while justifying the traditional use of the plant materials in the treatment of malaria, however, suggest their cautious use. PMID:27174028

    Eleven fossil woods belonging to seven families are described from a petrified wood forest of Mizoram. This fossil assemblage is derived from sediments belonging to the Tipam Group considered to be Late Miocene-Early Pliocene in age. The modern counterparts of the identified taxa are: Gluta L., Mangifera L. (Anacardiaceae), Bursera Jacq. ex L. (Burseraceae), Terminalia L. (Combretaceae), Shorea Roxb. (Dipterocarpaceae), Cynometra Linn., Dalbergia L. f., Millettia Wight et Arn.-Pongamia Vent, Ormosia Jacks. (Fabaceae), Artocarpus Forst. (Moraceae) and Madhuca Gmelin. (Sapotaceae). The genus Dalbergia is described for the first time from India. The modern environmental tolerances of the above taxa indicate the existence of a tropical warm and humid climate in Mizoram during the depositional period. The reconstructed climate data using Coexistence Approach (CoA) based on palaeoflora database of Mosbrugger and Utescher, along with other published data sets indicates an MAT (mean annual temperature) of 26.1-27.7 °C, a mean temperature of the warmest month (WMT) of 25.4-28.1 °C, a mean temperature of the coldest month (CMT) of 25.6-26 °C, and a mean annual precipitation (MAP) of 3180-3263 mm. These climatic interpretations are congruent with the data obtained from the anatomical features of all the fossil taxa. As all the fossil taxa possess diffuse porous wood, they further indicate a tropical climate with little seasonality. The majority of the taxa in the fossil assemblage generally have large vessels and simple perforation plates which indicate high precipitation. The present study provides vital evidence of floral exchange or migration between India and southeast Asia.

    In this study we estimated the extent of exudativory in Nycticebus bengalensis and examined whether exudates can be considered as fallback foods. This study was carried out in Trishna Wildlife Sanctuary, northeastern India, in winter (December-February) and summer (March and April). We estimated time-activity budget using instantaneous sampling and used continuous focal animal sampling to record all instances and durations of feeding, over a total of 177 hr. Feeding accounted for 22.3+/-2.2% of the activity budget, with no seasonal difference. Bengal slow lorises fed on exudates, nectar, fruit, bark, invertebrates and avian eggs. In addition to scraping they also obtained exudates by gouging holes into the bark of trees. In winter, lorises almost exclusively fed on exudates (94.3% of winter feeding time). In summer, exudates (67.3%) and nectar from one species (22.3%) dominated the diet. This study identifies the Bengal slow loris as the most exudativorous loris. Exudates rather than being a staple fallback food, seem to be a preferred, patchily distributed and common food in the diet of the Bengal slow loris. Exudativory in this species is characterized by high selectivity among species and seasonal variation, which may be related to variations in productivity of exudates and their chemical composition. An understanding of these factors is necessary for predicting the response of this species to human disturbance such as logging. This study also underscores the importance of protecting some of the common species such as Terminalia belerica on which the loris feeds during periods of scarcity.

    Ju/'hoan hunters from Nyae Nyae, near Tsumkwe in Namibia, demonstrate the manufacture of three fixative pastes made from plant extracts, and poison made from grubs and plant extracts. Ammocharis coranica and Terminalia sericea produce simple glue. Ozoroa schinzii latex mixed with carbonized Aristeda adscensionis grass is a compound adhesive. Composite poison is made from Chrysomelid grub viscera mixed with salivary extracts of Acacia mellifera inner bark and the tuber sap of Asparagus exuvialis. In order to document potential variability in the chaîne opératoire, and to eliminate inherent biases associated with unique observations, we studied manufacturing processes in three separate Nyae Nyae villages. Although there are methodological similarities in the Nyae Nyae area, we observed a few differences in contemporary traditions of poison manufacture.

    Ju/’hoan hunters from Nyae Nyae, near Tsumkwe in Namibia, demonstrate the manufacture of three fixative pastes made from plant extracts, and poison made from grubs and plant extracts. Ammocharis coranica and Terminalia sericea produce simple glue. Ozoroa schinzii latex mixed with carbonized Aristeda adscensionis grass is a compound adhesive. Composite poison is made from Chrysomelid grub viscera mixed with salivary extracts of Acacia mellifera inner bark and the tuber sap of Asparagus exuvialis. In order to document potential variability in the chaîne opératoire, and to eliminate inherent biases associated with unique observations, we studied manufacturing processes in three separate Nyae Nyae villages. Although there are methodological similarities in the Nyae Nyae area, we observed a few differences in contemporary traditions of poison manufacture. For example, some hunters make powder from Asparagus exuvialis tuber sap by boiling, reducing, hardening and grinding it, while others simply use heated sap.

    Green nanoparticle synthesis was achieved using environmentally acceptable plant extracts reducing and capping agents. The present study was based on assessments to the anticancer activities to determine the effect of synthesized silver nanoparticles (AgNPs) from three medicinal plants on human liver (HepG2) and prostate (PC3) cancer cell lines. The synthesis of AgNPs using Plumbago zeylanica (Pz), Semecarpus anacardium (Sa) and Terminalia arjuna (Ta) plant extracts in the reaction mixture was monitored by UV-visible spectroscopy. FTIR results clearly illustrated that the plant extracts containing prominent peaks of functional groups and biomolecules viz., tannins, phenols, flavonoids and triterpenoids those act as capping agents and involved in the stabilization of the synthesised silver nanoparticles. Synthesized AgNPs were spherical and cuboid in shape which is determined by SEM. Average size of the AgNPs were between 80-98, 60-95 and 34-70 nm for PzAgNPs, SaAgNPs and TaAgNPs, respectively. Further, the synthesized AgNPs were characterized by XRD, EDX, DLS and Zeta potential analysis. Moreover, the synthesized AgNPs exhibited a dose-dependent cytotoxicity against human liver and prostate cancer cell lines. The inhibitory concentration (IC50) values of HepG2, PC3 and Vero cells were found to be 70.97, 58.61, 96.41; 10.04, 42.77, 83.86; and 28.42, 41.78, 69.48 μg/ml for PzAgNPs, SaAgNPs and TaAgNPs at 48 h incubation. An induction of apoptosis was confirmed by DNA fragmentation, Hoechst, Rhodamine and AO/EtBr staining. The present results strongly suggested that the AgNPs synthesized using P. zeylanica, S. anacardium and T. arjuna extracts showed potential anticancer activity of HepG2 and PC3 cell lines.

    Background Traditional remedies are an integral part of Colombian culture. Here we present the results of a three-year study of ethnopharmacology and folk-medicine use among the population of the Atlantic Coast of Colombia, specifically in department of Bolívar. We collected information related to different herbal medicinal uses of the local flora in the treatment of the most common human diseases and health disorders in the area, and determined the relative importance of the species surveyed. Methods Data on the use of medicinal plants were collected using structured interviews and through observations and conversations with local communities. A total of 1225 participants were interviewed. Results Approximately 30 uses were reported for plants in traditional medicine. The plant species with the highest fidelity level (Fl) were Crescentia cujete L. (flu), Eucalyptus globulus Labill. (flu and cough), Euphorbia tithymaloides L. (inflammation), Gliricidia_sepium_(Jacq.) Kunth (pruritic ailments), Heliotropium indicum L. (intestinal parasites) Malachra alceifolia Jacq. (inflammation), Matricaria chamomilla L. (colic) Mentha sativa L. (nervousness), Momordica charantia L. (intestinal parasites), Origanum vulgare L. (earache), Plantago major L. (inflammation) and Terminalia catappa L. (inflammation). The most frequent ailments reported were skin affections, inflammation of the respiratory tract, and gastro-intestinal disorders. The majority of the remedies were prepared from freshly collected plant material from the wild and from a single species only. The preparation of remedies included boiling infusions, extraction of fresh or dry whole plants, leaves, flowers, roots, fruits, and seeds. The parts of the plants most frequently used were the leaves. In this study were identified 39 plant species, which belong to 26 families. There was a high degree of consensus from informants on the medical indications of the different species. Conclusions This study presents new

Out of 37 unifloral samples found 25 were contributed by Apis cerana indica, seven by A. dorsata and the remaining five by A. florea. Out of 14 multifloral samples five were contributed by A. cerana indica, five by A. dorsata and the remaining four by A. florea. Principal component analysis confirmed the palynological classification of the unifloral honey samples. Eighty-two bee-plant taxa belonging to forty four families were recovered. The predominant nectariferous taxa of the spring season were Acanthus ilicifolius, Avicennia marina, Bruguiera gymnorrhiza, Cocos nucifera, Eucalyptus globulus, Phoenix paludosa, Pongamia pinnata, Prosopis juliflora, Sonneratia apetala and Syzygium cumini. In the summer the predominant nectariferous taxa were Borassus flabellifer, C. nucifera, E. globulus, Syzygium cumini, Terminalia arjuna, Aegiceras corniculatum, P. paludosa and Sonneratia apetala while those of the winter were Brassica nigra, Coriandrum sativum, Zizyphus jujuba, Alstonia scholaris, E. globulus and Bruguiera gymnorrhiza. Very low (<0.09) HDE/P for 98% of the samples and absence of toxic palynotaxa assure that these honeys are suitable for human consumption. Quite extended honey flow period with spring and summer as best forage seasons for the honeybees and occurrence of 82% of these honeys with APC Group II, III and IV justify the sustainability of the present study area for establishing moderate to large-scale apicultural entrepreneurship.

    In the context of multiple forest management, multipurpose tree species which provide both timber and non-timber forest products (NTFP), present particular challenges as the potential of conflicting use for either product may be high. One key aspect is that the magnitude of conflict of use can be location specific, thus adding complexity to policy development. This paper focuses on the extent to which the potential for conflict of use in multipurpose tree species varies across the Amazonian lowland forests shared by Peru, Bolivia, Colombia, Ecuador and Venezuela, emphasizing the economic dimension of conflict. Based on a review of the current normative and regulatory aspects of timber and NTFP extraction in the five countries, the paper also briefly discusses the opportunities and constraints for harmonization of timber and NTFP management of multipurpose species across the region. It was found that about half of the 336 timber species reviewed across the five countries also have non-timber uses. Eleven timber species are multipurpose in all five countries: Calophyllum brasiliense, Cedrela odorata, Ceiba pentandra, Clarisia racemosa, Ficus insipida, Jacaranda copaia, Schefflera morototoni, Simarouba amara and Terminalia amazonia. Seven other multipurpose species occurred only in either Venezuela (Tabebuia impetiginosa, Spondias mombin, Pentaclethra macroloba, Copaifera officinalis, Chlorophora tinctoria, Carapa guianensis) or Ecuador (Tabebuia chrysantha).

    Background: Terminalia macroptera Guill. et Perr. (Combretaceae), Sida alba L. (Malvaceae), Prosopis africana Guill et Perr. Taub. (Mimosaceae), Bridelia ferruginea Benth. (Euphorbiaceae), and Vetiveria nigritana Stapf. (Asteraceae) are traditionally used in Togolese folk medicine to treat several diseases including microbial infections. Objective: This study aimed to investigate the antimicrobial, antioxidant, and hemolytic properties of the crude extracts of the above-mentioned plants. Materials and Methods: The antimicrobial and the antioxidant activities were assayed using the NCCLS microdilution method and the DPPH free radical scavenging, respectively. Human A+ red blood cells were used to perform the hemolytic assay. Phenolics were further quantified in the extracts using spectrophotometric methods. Results: Minimal inhibitory concentrations in the range of 230-1800 μg/ml were recorded in the NCCLS broth microdilution for both bacterial and fungal strains with methanol extracts. The DPPH radical scavenging assay yielded interesting antioxidant activities of the extracts of P. africana and T. macroptera (IC50 values of 0.003 ± 0.00 μg/ml and 0.05 ± 0.03 μg/ml, respectively). These activities were positively correlated with the total phenolic contents and negatively correlated with the proanthocyanidin content of the extracts. The hemolytic assay revealed that great hemolysis occurred with the methanol extracts of T. macroptera, S. longepedunculata, and B. ferruginea. Conclusion: These results support in part the use of the selected plants in the treatment of microbial infections. In addition, the plant showed an interesting antioxidant activity that could be useful in the management of oxidative stress. PMID:22518084

    Context Ischemic-reperfusion injury is accompanied by a decreased contractility of the myocardium. Positive-inotropic agents have proven useful for treating this condition but may exert serious side-effects. Objective In this study, aqueous preparations from Abelmoschus esculentus L. Moench (Malvaceae), Annona muricata L. (Annonaceae), Bixa orellana L. (Bixaceae), Cecropia peltata L. (Moraceae), Erythrina fusca Lour. (Fabaceae), Psidium guajava L. (Myrtaceae) and Terminalia catappa L. (Combretaceae) were evaluated for their ability to improve the decreased contractility of isolated guinea pig atria after hypoxic stress. Materials and methods Guinea pig atria isolated in Ringer-Locke buffer gassed with 100% O2 at 30 °C were exposed for 5 min to hypoxia, then allowed to recover in oxygenated buffer alone or containing a single plant extract (0.001-1 mg/mL). The contractility (g/s) and beating frequency (beats/min), as well as troponin C contents of the bathing solution (ng/mL), were determined and expressed as means ± SDs. Results The extracts of A. muricata, B. orellana, C. peltata and T. catappa caused an increase in the contractility compared to untreated atria of 340 ± 102%, 151 ± 13%, 141 ± 14% and 238 ± 44%, respectively. However, the latter two preparations increased the troponin C contents of the bathing solution to 36 ± 11 and 69 ± 33, compared to the value of 11 ± 3 ng/mL found with untreated atria. Conclusions Preparations from A. muricata and B. orellana may possess positive-inotropic properties which may improve the contractility of the post-hypoxic myocardium. Studies to assess their usefulness in ischemic-reperfusion injury are warranted. PMID:26730936

    The majority of the plant materials used in herbal medicine is procured from the markets in the form of dried or powdered plant parts. It is essential to use authentic plant materials to derive the benefits of herbal medicine. However, establishing the identity of these plant materials by conventional taxonomy is extremely difficult. Here we report a case study in which the species identification of the market samples of Sida cordifolia was done by DNA barcoding. As a prelude to species identification by DNA barcoding, 13 species of Sida were collected, and a reference DNA barcode library was developed using rbcL, matK, psbA-trnH and ITS2 markers. Based on the intra-species and inter-species divergence observed, psbA-trnH and ITS2 were found to be the best two-marker combination for species identification of the market samples. The study showed that none of the market samples belonged to the authentic species, S. cordifolia. Seventy-six per cent of the market samples belonged to other species of Sida. The predominant one was Sida acuta (36%) followed by S. spinosa (20%), S. alnifolia (12%), S. scabrida (4%) and S. ravii (4%). Such substitutions may not only fail to give the expected therapeutic effect, but may also give undesirable effects as in case of S. acuta which contains a 6-fold higher amount of ephedrine compared to the roots of S. cordifolia. The remaining 24% of the samples were from other genera such as Abutilon sp. (8%), Ixonanthes sp., Terminalia sp., Fagonia sp., and Tephrosia sp. (4% each). This observation is in contrast to the belief that medicinal plants are generally substituted or adulterated with closely related species. The current study strongly suggests that the raw drug market samples of herbal medicines need to be properly authenticated before use, and DNA barcoding has been found to be suitable for this purpose.

Although there are methodological similarities in the Nyae Nyae area, we observed a few differences in contemporary traditions of poison manufacture.

The Ju/'hoan hunting kit provides insights for archaeologists, but we must exercise caution when looking for continuity between prehistoric and historical technical systems. Some traditions have been lost to modern hunters, while others are new. We should also expect variability in the Stone Age because of geographically restricted resources. Simple glue, compound adhesive, and poison recipes identified in the Stone Age have no modern equivalents. By about 60,000 years ago at Diepkloof, simple glue was used for hafting tools, but at similarly-aged Sibudu there are recipes that combine red ochre powder with plant and/or animal ingredients. At Border Cave, novel poisons and compound adhesives were used in the Early Later Stone Age. It is possible that the complexity that we record in the manufacture of fixative pastes and poison used by Ju/'hoan hunters represents a hafting system both similar to and different from that observed at the Stone Age sites of Diepkloof

    Mastitis (inflammation of mammary gland) is a most devastating disease condition in terms of economic losses occurring throughout the world. The etiological agents may vary from place to place depending on climate; animal species and animal husbandry and include wide variety of gram positive and gram negative bacteria; and fungi. They may be either contagious viz. Staphylococcus aureus; Streptococcus agalactiae or environmental viz. S. dysgalactiae, S. uberis, Corynebacterium bovis and Coagulase negative Staphylococcus. Conventional diagnostic tests viz. California Mastitis Test (CMT); R-mastitest and Mast-O-test methods are applied under field conditions; whereas somatic cell count and Bulk Tank Somatic Cell Count (BTSCC) are useful for early mastitis detection and detection of sub clinical or chronic mastitis respectively. In vitro culture based diagnosis require further study as they can detect only viable cells. The advent of Polymerase Chain Reaction (PCR) technology along with its various versions like multiplex and real time PCR has improved the rapidity and sensitivity of diagnosis. Circulating micro RNA (miRNA) based diagnosis; immune assay and proteomics based detection along with biochips and biosensors prove to be asset to diagnosticians for advanced diagnosis of this economically important condition. Improvement of milking hygiene; implementation of post-milking teat disinfection; regular control of the milking equipments; implementation of milking order; Improvement of bedding material are the general measures to prevent new cases of mastitis. The use of antibiotics (intramammary infusions; bacteriocins) and herbs (Terminalia spp.) are important for prophylaxis and therapeutics. Vaccines viz. cell based; Recombinant (staphylococcal enterotoxin type C mutant) or chimeric (pauA); live (S. uberis 0140J stain based) and bacterial surface extract based; DNA-based and DNA-protein based have greatly aided in management of bovine mastitis.

    Savanna ecosystems cover a large fraction of the terrestrial landscape with a shifting mosaic of vegetation that is poorly understood. Vegetation dynamics in savannas are believed to be triggered by variation in climate forcing with potential local and regional scale feedbacks on climate and with nonlinear behavior, such as self-organization. Recent debate has brought attention to uncertainty regarding the role of savannas in global carbon and water cycles, identifying the need for data that can address the coupled water and carbon dynamics of these sensitive ecosystems. We report results from a 30-day field campaign conducted in southern Africa near Ghanzi, Botswana along the Kalahari Transect. This water-limited site is ideal for studies of soil and plant water relations because high spatial and temporal variability in rainfall has direct effects on vegetation function, extent, and composition. We characterized the functional response of tree/grass/bare soil mosaics during a prolonged drydown following a large rain event (85 mm) at the end of the 2002 wet season. Net radiation, sensible, latent and soil heat fluxes, carbon dioxide exchange, soil moisture, soil temperature, and vegetation temperatures were measured at two sites, one dominated by woody vegetation (Acacia and Terminalia) and the other composed of native grasses, shrubs, and bare soil. We characterized the vegetation structure within the footprints of both towers with measurements of leaf area, fractional vegetation cover, and profiles of aboveground and belowground biomass. Additionally, leaf-level gas exchange measurements were conducted on dominant species. Soil moisture decayed from a peak of 0.28 after the storm to 0.05, measured 5 cm below the soil surface. The drydown resulted in a continual increase in the daytime Bowen ratio, a decrease of leaf-level evapotranspiration, and reduced net ecosystem exchange of CO2. Biophysical differences between C3 trees and C4 grasses were evident from vapor

The advent of Polymerase Chain Reaction (PCR) technology along with its various versions like multiplex and real time PCR has improved the rapidity and sensitivity of diagnosis. Circulating micro RNA (miRNA) based diagnosis; immune assay and proteomics based detection along with biochips and biosensors prove to be asset to diagnosticians for advanced diagnosis of this economically important condition. Improvement of milking hygiene; implementation of post-milking teat disinfection; regular control of the milking equipments; implementation of milking order; Improvement of bedding material are the general measures to prevent new cases of mastitis. The use of antibiotics (intramammary infusions; bacteriocins) and herbs (Terminalia spp.) are important for prophylaxis and therapeutics. Vaccines viz. cell based; Recombinant (staphylococcal enterotoxin type C mutant) or chimeric (pauA); live (S. uberis 0140J stain based) and bacterial surface extract based; DNA-based and DNA-protein based have greatly aided in management of bovine mastitis.

    Mwingi District lies within the Kenyan Arid and Semiarid lands (ASALs) in Eastern Province. Although some ethnobotanical surveys have been undertaken in some arid and semiarid areas of Kenya, limited studies have documented priority medicinal plants as well as local people's awareness of conservation needs of these plants. This study sought to establish the priority traditional medicinal plants used for human, livestock healthcare, and those used for protecting stored grains against pest infestation in Mwingi district. Further, the status of knowledge among the local people on the threat and conservation status of important medicinal species was documented. This study identified 18 species which were regarded as priority traditional medicinal plants for human health. In terms of priority, 8 were classified as moderate, 6 high, while 4 were ranked highest priority species. These four species are Albizia amara (Roxb.) Boiv. (Mimosacaeae), Aloe secundiflora (Engl. (Aloaceae), Acalypha fruticosa Forssk. (Euphorbiaceae) and Salvadora persica L. (Salvadoraceae). In regard to medicinal plants used for ethnoveterinary purposes, eleven species were identified while seven species were reported as being important for obtaining natural products or concoctions used for stored grain preservation especially against weevils. The data obtained revealed that there were new records of priority medicinal plants which had not been documented as priority species in the past. Results on conservation status of these plants showed that more than 80% of the respondents were unaware that wild medicinal plants were declining, and, consequently, few of them have any domesticated species. Some of the species that have been conserved on farm or deliberately allowed to persist when wild habitats are converted into agricultural lands include: Croton megalocarpus Hutch., Aloe secundiflora, Azadirachta indica A. Juss., Warburgia ugandensis Sprague, Ricinus communis L. and Terminalia brownie Fresen

    India is one of the growing economy in the world and energy is a critical input to sustain the growth of development. Country aims at security and efficiency of energy. Though fossil fuel will continue to play a dominant role in energy scenario but country is committed to global environmental well being thus stressing on environment friendly technologies. Concerns of energy security in this changing climatic situation have led to increasing support for the development of new renewable source of energy. Government though is determined to facilitate bio-energy and many projects have been established but initial after-affects more specifically on the domestic fuelwood are evident. Even the biomass power generating units are facing biomass crisis and accordingly the prices are going up. The CDM projects are supporting the viability of these units resultantly the Indian basket has a large number of biomass projects (144 out of total 506 with 28 per cent CERs). The use for fuelwood as a primary source of energy for domestic purpose by the poor people (approx. 80 per cent) and establishment of bio-energy plants may lead to deforestation to a great extent and only solution to this dilemma is to shift the wood harvest from the natural forests to energy plantations. However, there is conspicuous lack of knowledge with regards to the fuelwood characteristics of fast growing tree species for their selection for energy plantations. The calorific value of the species is important criteria for selection for fuel but it is affected by the proportions of biochemical constituents present in them. The aim of the present work was to study the biomass production, calorific value and chemical composition of different short rotation tree species. The study was done from the perspective of using the fast growing tree species for energy production at short rotation and the study concluded that short rotation tree species like Gmelina arborea, Eucalyptus tereticornis, Pongamia pinnata,Terminalia

    Groundwater recharge estimations in semi-arid areas are challenging, especially in developing countries such as large parts of Sub-Saharan Africa, where data is generally scarce. Due to high heterogeneity in soil characteristics, vegetation and land use as well as spatially and temporally highly variable rainfall, precise site studies are necessary in order to characterize processes and quantify groundwater recharge rates. The stable isotope deuterium, 2H has been shown to be particularly suitable for such investigations. In this study, a field experiment using deuterium as an artificial tracer (2H2O, 70% deuterated water) was conducted to characterize movement of water during and after a synthetic rain event. The study was carried out in the framework of the project SASSCAL (Southern African Science Service Centre for Climate Change and Adaptive Land Management) in the Niipele catchment of the Cuvelai-Etosha Basin in Namibia at two locations differing in both soil and vegetation type: A forest site dominated by terminalia sericea, baikiaea plurijuga, burkea africana and acacia erioloba with deep pure sand soil and a shrub-/woodland site characterized by smaller burkea africana, borchemia discolor and acacia erioloba on a dark loamy sand soil underlain by a thick layer of calcrete. At both locations, soils were first saturated to trigger typical rainy season conditions and avoid immediate evaporation of the deuterated water. Subsequently, 500 ml of 2H2O was applied homogenously over a 0.25 m2 test plot at 25 cm depth. Finally, a 10 mm artificial rain event was applied onto the plot. Soil samples were collected every 10 cm to a maximum depth of 2.5 m with an Eijkelkamp hand auger after 1, 2, and 5 (respective 10) days. From these, soil water is extracted in the laboratory and subsequently analyzed for deuterium concentrations using a Picarro L2120-i cavity-ringdown (CRD) water vapor analyzer after vaporization. Additionally, grain size distribution, water content

    Background Cardiovascular disorders (CVDs) are the leading cause of disease burden worldwide. Apart from available synthetic drugs used in CVDs, there are many herbal formulations including POL-10 (containing 10 herbs), which have been shown to be effective in animal studies but POL-10 was found to cause tachycardia in rodents as its side effect. This study was designed to modify the composition of POL-10 for better efficacy and/or safety profile in CVDs. Methods To assess the antidyslipidemic, antihypertensive and endothelial modulatory properties of two herbal formulations, (ZPTO and ZTO) containing Z: Zingiber officinalis, P: Piper nigrum, T: Terminalia belerica and O: Orchis mascula, different animal models including, tyloxapol and high fat diet-induced dyslipidemia and spontaneously hypertensive rats (SHR) were used. Effect on endothelial function was studied using isolated tissue bath set up coupled with PowerLab data acquisition system. The antioxidant activity was carried out using DPPH radical-scavenging assay. Results Based on preliminary screening of the ingredients of POL-10 in tyloxapol-induced hyperlipidemic rats, ZPTO and ZTO containing four active ingredients namely; Z, P, T and O were identified for further studies and comparison. In tyloxapol-induced hyperlipidemic rats, both ZPTO and ZTO caused significant reduction in serum triglyceride (TG) and total cholesterol (TC). In high fat diet-fed rats, ZPTO decreased TC, low-density lipoproteins cholesterol (LDL-C) and atherogenic index (AI). ZTO also showed similar effects to those of ZPTO with additional merits being more effective in reducing AI, body weight and more importantly raising high-density lipoproteins. In SHR, both formulations markedly reduced systolic blood pressure, AI and TG levels, ZTO being more potent in reversing endothelial dysfunction while was devoid of cardiac stimulatory effect. In addition, ZTO also reduced LDL-C and improved glucose levels in SHR. In DPPH radical

    Abstract The New World species of the subgenera Allotrichoma Becker and Neotrichoma (new subgenus) are revised, including a phylogenetic analysis of the species groups and subgenera within the genus Allotrichoma. For phylogenetic perspective and to document the monophyly of the genus Allotrichoma and its included subgenera and species groups, we also provide a cladistic analysis of genera within the tribe Hecamedini. The ingroup included seven exemplar congeners from within Allotrichoma. Outgroup sampling included exemplars of other genera within Hecamedini and from the putative sister group, Lipochaetini, and to root the analysis, we used an exemplar of the tribe Discocerinini. Analyses with successive weighting and implied weighting recovered a monophyletic Allotrichoma and indicated clades within the genus. Eight new species are described (type locality in parenthesis): Allotrichoma bifurcatum (Utah. Utah: Lake Shore (40°06.9'N, 111°41.8'W; 1370 m)), Allotrichoma dynatum (Oregon. Benton: Finley National Wildlife Refuge (44°24.6'N, 123°19.5'W)), Allotrichoma occidentale (Oregon. Lake: Lakeview (44 km E; Drake Creek; 42°11'N, 119°59.3'W)), Allotrichoma robustum (California. Kern: Kern River (35°16.1'N, 119°18.4'W)), Allotrichoma sabroskyi (New Mexico. Sandoval: La Cueva (Junction of Highways 126 and 4; 35°52'N, 106°38.4'W; 2342 m)), Allotrichoma wallowa (Oregon Baker: Goose Creek (35 km E Baker City; 44°49.2'N, 117°27.79'W; 825 m)), Allotrichoma baliops (Florida.

    The global burden of bacterial infections is very high and has been exacerbated by increasing resistance to multiple antibiotics. Antibiotic resistance leads to failed treatment of infections, which can ultimately lead to death. To overcome antibiotic resistance, it is necessary to identify new antibacterial agents. In this study, a total of 662 plant extracts (diverse parts) from 222 plant species (82 families, 177 genera) were screened for antibacterial activity using the agar cup plate method. The aqueous and methanolic extracts were prepared from diverse plant parts and screened against eight bacterial (two Gram-positive and six Gram-negative) species, most of which are involved in common infections with multiple antibiotic resistance. The methanolic extracts of several plants were shown to have zones of inhibition ≥ 12 mm against both Gram-positive and Gram-negative bacteria. The minimum inhibitory concentration was calculated only with methanolic extracts of selected plants, those showed zone of inhibition ≥ 12 mm against both Gram-positive and Gram-negative bacteria. Several extracts had minimum inhibitory concentration ≤ 1 mg/mL. Specifically Adhatoda vasica, Ageratum conyzoides, Alangium salvifolium, Alpinia galanga, Andrographis paniculata, Anogeissus latifolia, Annona squamosa, A. reticulate, Azadirachta indica, Buchanania lanzan, Cassia fistula, Celastrus paniculatus, Centella asiatica, Clausena excavate, Cleome viscosa, Cleistanthus collinus, Clerodendrum indicum, Croton roxburghii, Diospyros melanoxylon, Eleutherine bulbosa, Erycibe paniculata, Eryngium foetidum, Garcinia cowa, Helicteres isora, Hemidesmus indicus, Holarrhena antidysenterica, Lannea coromandelica, Millettia extensa, Mimusops elengi, Nyctanthes arbor-tristis, Oroxylum indicum, Paederia foetida, Pterospermum acerifolium, Punica granatum, Semecarpus anacardium, Spondias pinnata, Terminalia alata and Vitex negundo were shown to have significant antimicrobial activity.

    identify additional six sub-classes based on the dominant species in each class: Colophospermum mopane woodland, Colophospermum mopane shrubland, Cataphractes alexandri woodland, Acacia nebrownii shrubland, mixed Combretum species woodland and Terminalia prunioides woodland. Second, we used quantitative methods to relate satellite-based vegetation indices to the biometric properties measured on the ground. We found a correlation among measured height, diameter and canopy cover of woody vegetation and used this to improve the correlation between cover and Normalized Difference Vegetation Index (NDVI). We showed that the Soil Adjusted Total Vegetation Index (SATVI) and Normalized Difference Water Index (NDWI) were related to both greenness and density at a site. In order to measure grass biomass in the field, we calibrated Disc Pasture Mater by clipping, weighing and drying grass in 1m^2 plots, in the dry and wet seasons, with resulting R^2 of 0.87 and 0.83, respectively. MODIS-derived leaf area index (LAI) data was best correlated with dry grass biomass. We used these correlations to produce detailed maps of each vegetation parameter for the whole park. These maps will provide a baseline to employ historical imagery to better understand the effects of the park's management and changing grazing pressure on vegetation structure.

    This study was designed to investigate the role of a traditional buzui recipe in anti-inebriation treatment. Buzui consists of Fructus Schisandrae Chinensis, Fructus Chebulae, Fructus Mume, Fructus Crataegi, Endothelium Corneum Gigeriae Galli, and Excrementum Bombycis. The buzui mixture was delivered by gavage, and ethanol was delivered subsequent to the final treatment. The effects of buzui on the righting reflex, inebriation rates, and the survival curve are depicted. Blood alcohol concentrations, alanine aminotransferase (ALT) levels, aspartate aminotransferase (AST) levels, and alkaline phosphatase (ALP) levels were recorded. The activities of alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH), and superoxide dismutase (SOD), as well as malonaldehyde (MDA) levels, were also measured. Our results demonstrated that a traditional buzui recipe showed significant effects on promoting wakefulness and the prevention of acute alcohol intoxication, accelerating the metabolism of alcohol in the liver and reducing the oxidative damage caused by acute alcoholism.

    Effects of 15 kinds of herbal drugs, vegetables and chemicals on lex-dependent sfi-SOS response were determined by micropersistent and/or pulse models induced by 4-Nitroquinoline-N-oxide (4NQO) and Mitomycin C (MMC) in Escherichia coli(E. coli) PQ37 and PQ35, respectively. Results showed the water extract of Rhizoma Polygonati (RP), Fructus Chebulae (FC), Radix Polygoni Multiflori (RPM), Fructus Ligustri Lucidi (FLL), Bulbus Fritillariae Thunbergii (BFT), shell of water chestnut with a pedicle, Chinese chives juice, and solutions of 5-Fluorouracil, Tannic acid and garlicin could inhibit SOS responses with a dose-response relationship and suggested the inhibitory effects took place both inside and outside E. coli cells. Water extract of FC, FLL, BFT, shell of water chestnut with a pedicle, Chinese chives juice and solution of 5-Fluorouracil and Tannic acid could intracellularly inhibit SOS responses induced by MMC in E. coli PQ35, and acetone extract of Grifola Frondosa (GF) could extracellularly inhibit SOS responses in E. coli PQ37 and intracellularly in PQ35 induced by 4NQO or MMC. Water extract of raw hawthorn. Radix Angelicae Duhuricae (RAD), Radix Ophiopogonis (RO), and 5-Fluorodeoxyuridine could extracellularly inhibit SOS responses induced by 4NQO in E coli PQ37. The possible mechanisms of intracellular inhibition and antidamage repair were discussed in the paper.
