OBJECTIVETo study the chemical constituents of Daphne odora var. margirmta.
METHODThe compounds were isolated and purified by column chromatography of silica gel, ODS, Sephadex LH-20, and their structures were identified by UV, 1H-NMR, 13C-NMR, MS and CD spectroscopic methods.
RESULTTen compounds were elucidated as wikatrols B (1), kaempferol (2), daphnodorin B (3), daphnodorin D2 (4), daphnodorin A (5), daphnodorin C (6), daphnodorin D1 (7), daphnodorin I (8), daphnetin (9), daphnoretin (10).
CONCLUSIONCompounds 1,2,4 were obtained from this plant for the first time,and compound 1 was isolated firstly from the genus Daphne.

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.
