Abstract:
Phytochemical investigation was carried out on the seeds of Vigna umbellata. The 70% ethanol extract of the seeds of V. umbellata was subjected to silica gel, Sephadex LH-20, ODS column chromatographies and preparative HPLC. The structures of the isolated compounds were elucidated on the basis of NMR and ESI-MS spectroscopic data Eight compounds were obtained and identified as carboxyatractyligenin (1), 2beta-O-beta-D-glucopyranosyl-15alpha-hydroxy-kaur-16-ene-18,19-dicarboxylic acid (2), 2beta-O-(beta-D-glucopyranosyl) atractyligenin (3), 3R-O-[beta-L-arabinopyranosyl-(1-6) -beta-D-glucopyranosyl] oct-1-ene-3-ol (4), (6S, 7E, 9R) -roseoside (5), liriodendrin (6), resveratrol (7) and maltol (8). Compounds 1-7 were isolated from Vigna genus for the first time, and compound 8 was isolated from V. umbellata for the first time.
