A D-galactose-binding lectin agglutinating human erythrocytes has been purified from the seeds of the Indian coral tree (Erythrina variegata (Linn.) var. orientalis (Linn.) Merrill] by affinity chromatography on acid-treated Sepharose-6B gel. It has a higher reactivity for O-group erythrocytes. The lectin is a glycoprotein having a ...

Phytochemical analysis of the root bark of Bauhinia variegata Linn yielded a new flavanone, (2S)-5,7-dimethoxy-3',4'-methylenedioxyflavanone (1) and a new dihydrodibenzoxepin, 5,6-dihydro-1,7-dihydroxy-3,4-dimethoxy-2-methyldibenz [b,f]oxepin (2) together with three known flavonoids (3-5). The structures of the new compounds were determined on the basis of ...
Bauhinia variegata Linn. (Leguminosae) is commonly known as 'Kachnar' in Hindi. It is distributed almost throught India. Its powdered bark is traditionally used for tonic, astrain, ulcers. It is also useful in skin diseases. The roots are used as antidote to snake poison. The present article deals with the isolation and structural elucidation of a novel ...
Objectives:To evaluate the ethanolic and aqueous extracts of Bauhinia variegata Linn. for in vitro antioxidant and antihyperlipidemic activity.Materials and Methods:Ethanolic and aqueous extracts of the stem bark and root of B. variegata Linn. were prepared and assessed for in vitro antioxidant activity by various ...
A flavanone has been isolated first time from the stem of Bauhinia variegata, and its structure was identified by colour reactions and spectral analysis. In a search for novel anticancer compounds from medicinal plants, the isolated flavanone was tested for cytotoxic activity against 57 human tumour lines, representing leukaemia, non-small cell lung, colon, central nervous ...
The amino acids of the chymotrypsin inhibitor (ECI) from the Erythrina variegata seeds have been sequenced. The sequence was solved by analysis of peptides derived from the protein by enzymatic digestions with trypsin and Staphylococcus aureus V8 proteinase, as well as by chemical cleavage with o-iodosobenzoic acid. The ECI consists of 179 amino acid residues with a ...
A new flavone glycoside m.f. C(30)H(36)O(15) m.p. 252-253 degrees C, [M]+ 636 (EIMS) was isolated from the acetone soluble fraction of the concentrated 95% ethanolic extract of the seeds of Bauhinia variegata (Linn). It was identified as 5-hydroxy7,3',4',5'-tetra-methoxyflavone 5-O-beta-D-xylopyranosyl-(1-->2)-alpha-L-rhamnopyranoside (1) by various ...
Three isolectins were isolated from seeds of Erythrina variegata (Linn.) var. Orientalis by ion-exchange chromatography, followed by affinity chromatography on lactose-Sepharose 4B and acid-treated Sepharose 4B columns. The purified isolectins (EVLI, EVLII and EVLIII) are all specific for galactopyranosides and N-acetylgalactosamine, and their affinities ...
The nephroprotective activity of the ethanolic extract of Bauhinia variegata (Linn.) whole stem against cisplatin-induced nephropathy was investigated by an in vivo method in rats. Acute nephrotoxicity was induced by i.p. injection of cisplatin (7 mg/kg of body weight (b.w.)). Administration of ethanol extract at dose levels of 400 and 200 mg/kg (b.w.) to ...
A new triterpene saponin, named as 23-hydroxy-3alpha-[O-alpha-L-1C4-rhamnopyranosyl-(1"-->4')-O-alpha-L-4C1-arabinopyranosyl-oxy]olean-12-en-28-oic acid O-alpha-L-1C4-rhamnopyranosyl-(1""'-->4"")-O-beta-D-4C1-glucopyranosyl-(1""-->6"')-O-beta-D-4C1-glucopyranosyl ester (9), was isolated from the leaves of Bauhinia variegata Linn. In addition, six ...

We transplanted Nuphar variegata with submersed leaves only into natural lake sediments in pH-, [CO(2)]-, depth-, and temperature-controlled greenhouse tanks to test the hypotheses that more fertile sediment, lower free [CO(2)], and shallower depth would all stimulate the development of floating leaves. Sediment higher in porewater [NH(4)(+)] favored floating leaf development. ...
The alkaloidal components of eight Erythrina plants (Leguminosae), E. arborescence Roxb., E. orientalis (L.) Murr, E. crysta-galli Linn, E. crysta-galli (L.) cv. Maruba Deiko H. Murata, E. x bidwilli Lindl, E. poeppigiana (Walp) O. F. Cook, E. glauca Willd, and E. variegata L. were examined. As a result of this study, five new oxo-erythrinan alkaloids, ...
The structural requirements for the interaction of asparagine-linked oligosaccharide moieties of glycoproteins with Erythrina variegata agglutinin (EVA) were investigated by means of affinity chromatography on an EVA-Sepharose column. Some of the branched poly-N-acetyllactosamine-type oligosaccharides obtained from human erythrocyte band 3 glycoprotein were found to show high ...
The Kunitz-type trypsin inhibitors, ETIa and ETIb, and chymotrypsin inhibitor ECI were isolated from the seeds of Erythrina variegata. The proteins were extracted from a defatted meal of seeds with 10 mM phosphate buffer, pH 7.2, containing 0.15 M NaCl, and purified by DEAE-cellulose and Q-Sepharose column chromatographies. The stoichiometry of trypsin inhibitors with trypsin ...
Objective:To investigate the effect of the methanolic extract of Erythrina variegata (Linn.) var Orientalis (Fabaceae) seeds (MEEV) in reducing the cholesterol levels and as well as antioxidant in experimentally induced hyperlipidemic rats.Materials and Methods:Doses of 200 and 400 mg/kg of the extract were evaluated for its effect on lipid profile, ...
