Abstract:
Phytochemical studies of the the herb Sarcopyramis bodinieri var. delicate (Melastomataceae) have been carried out. The compounds were separated by repeated D101 macroporous adsorption resin column combined with Sephadex LH-20, ODS, and silica gel chromatgrophy. The structures were identified on the basis of extensive spectroscopic data analysis, and by comparison of their spectral data with those reported. Eight flavonoid compounds isolated from the ethyl acetate extract was identified as isorhamnetin (1), quercetin (2), isorhamnetin-3-O-beta-D-glucopyranoside (3), quercetin-3-O-beta-D-glucopyranoside (4), isorhamnetin-3-O-(6"-acetyl)-beta-D-glucopyranoside (5), isorhamnetin-3-O-(2"-acetyl)-beta-D-glucopyranoside (6), quercetin-3-O-(6"-acetyl)-beta-D-glucopyranoside (7), and quercetin- 3-O-(6"-O-E-p-coumaroyl)-beta-D-glucopyranoside (8). All of the compounds were separated from the genus of Sarcopyramis for the first time.
