Chemical constituents from Vigna umbellate
摘要
Abstract
AIM To study the chemical constituents from Vigna umbellata Ohwi et Ohashi.METHODS The ethyl acetate fraction of 80％ ethanol extract from V.umbellata was isolated and purified by silica,Sephadex LH-20 and ODS column,then the structures of obtained compounds were identified by spectral data and physicochemical properties.RESULTS Twelve compounds were isolated and elucidated as (+) catechin (1),(-) epicatechin (2),3-furanmethanol-β-D-glucopyranoside (3),myricetin-3-O-β-D-glucopyranoside (4),quercetin7-O-β-D-glucopyranoside (5),(+) catechin-3-O-β-D-glucopyranoside (6),(+) catechin-5-O-β-D-glucopyranoside (7),quercetin-3 '-O-α-L-rhamnoside (8),(±) dihydroquercetin (9),quercetin (10),ethyl gallate (11),propanediol (12).CONCLUSION All the compounds are isolated from V.umbellata for the first time,and compounds 4,8,9,11,12 are first obtained from genus Vigna.关键词
