ABSTRACT
Sargentodoxae Caulis was prepared from the stems of Sargentodoxa cuneata. Twenty compounds from the the stems of S. cuneata collected in Huangshan Mountain, Anhui province, were isolated and purified by column chromatography on macroporous resin (HPD100), silica gel, Sephadex LH-20 and semi-preparative HPLC. Their structures were elucidated on the basis of physico-chemical properties and spectral data analyses as (7R,8S)-3,3 '-5-trimethoxy-4,9-dihydroxy-4',7-expoxy-5',8-lignan-7'-en-9'-oic acid 4-O-beta-D-glucopyranoside(1), 1-O-(vanillic acid) -6-O-vanilloyl-beta-D-glucopyranoside(2), 4-hydroxyphenylethyl-6-O-coumaroyl-beta-D-glucopyranoside(3), citrusin B(4), cinnamoside(5), (-) -isolariciresinol 4'-O-beta-D-glucopyranoside (6), (-) -isolariciresinol 4-O-beta-D-glucopyranoside (7), 1-O-(vanillic acid) -6-(3", 5"-dimethoxy-galloyl) -beta-D-glucopyranoside (8), 4-hydroxyphenyl-ethyl-6-O-(E) -caffeoyl-beta-D-glucopyranoside (9), (-)-syringaresinol 4'-O-beta-D-glucopyranoside (10), (-)-syringaresinol di-O-beta-D-glucopyranoside (11), aegineoside (12), calceolarioside B (13), 4-hydroxy-3-methoxy-acetophenone-4-O-alpha-L-rhamnopyranosyl-(1 --> 6)-beta-D-glucopyranoside (14), 4-hydroxy-3-methoxy-acetophenone-4-O-beta-D-apiofuranosyl-(1 --> 6) -beta-D-glucopyranoside (15), (-) -epicatechin (16), salidroside (17), 3,4-dihydroxy-phenyl ethyl-beta-D-glucopyranoside (18), chlorogenic acid (19) and protocatechuic acid (20).
