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.
