Abstract:
OBJECTIVETo study the flavonoids in the leaves of Apocynum ventum.
METHODCompounds were separated by repeated polyacrylamide column chromatgraphy combined with Sephadex LH-20 column chromatgraphy, their structures were confirmed by the analysis of spectral data and physicochemical properties.
RESULTSix compounds were isolated from A. ventum. They were elucidated as quercetin (1), kaempferol (2), kaempferol-3-O-(6"-O-acetyl)-beta-D-glucopyranoside (3), quercetin-3-O-(6"-O-acetyl )-beta-D-glucopyranoside (4), quercetin-3-O-(6"-O-acetyl)-beta-D-galactopyranoside (5), kaempferol-7-O-alpha-L-rhamnopyranoside (6).
CONCLUSIONCompound 5 and 6 were isolated from the genus Apocynum for the first time.
