摘要：

Four new triterpenoid saponins, named hookerosides A-D, were isolated from Pterocephalus hookeri. Based on chemical and spectral evidence, their structures were determined as 3-O-beta-D-glucopyranosyl(1 --> 4)-beta-D-xylopyranosyl(1 --> 3)-alpha-L-rhamnopyranosyl(1 --> 2)-beta-D-Xylopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranoside, 3-O-beta-D-xylopyranosyl(1 --> 4)-beta-D-glucopyranosyl(1 --> 4)-beta-D-xylopyranosyl(1 --> 3)-alpha-L-rhamnopyranosyl(1 --> 2)-beta-D-xylopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl(1 --> 6)-beta-D-glucopyranoside, 3-O-alpha-L-rhamnopyranosyl(1 --> 2)-beta-D-xylopyranosyl(1 -->4)-beta-D-glucopyranosyl(1 --> 4)-beta-D-xylopyranosyl(1 --> 3)-alpha-L-rhamnopyranosyl(1 --> 2)-beta-D-Xylopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl(1 --> 6)-beta-glucopyranoside and oleanolic acid 3-O-alpha-L-rhamnopyranosyl(1 --> 2)-beta-D-xylopyranosyl(1 --> 4)-beta-D-glucopyranosyl(1 --> 4)-beta-D-xylopyranosyl(1 --> 3)-alpha-L-rhamnopyranosyl(1 --> 2)-beta-D-xylopyranoside, respectively.
