OBJECTIVETo study the chemical constituents in the stems of Kadsura oblongifolia.

METHODThe chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.

RESULTSeven compounds named kaempferol-3-O-alpha-L-arabinofuranoside (1), kaempferol-3-O-alpha-D-arabinopyranoside (2), quercetin-3-O-alpha-D-arabinopyranoside (3), quercetin-3-O-alpha- L-arabinofuranoside (4), quercetin-3-O-beta-D-glucopyranoside (5), quercetin (6), kaempferol (7) were isolated and identified.

CONCLUSIONCompounds 1-7 were obtained from this plant for the first time. Compounds 1-4 were isolated from Schisandraceae family for the first time.
