摘要：

Seven new saponins, all glycosides of hederagenin (3 beta,23-dihydroxyolean-12-en-28-oic acid), were isolated from the stem of Pometia eximia along with hederagenin and two known saponins. Their structures were established as 28-O-beta-D-apiosyl(1 --> 2)-beta-D-glucopyranosyl-, 3-O-alpha-L-arabinofuranosyl(1 --> 3)[alpha-L-rhamnopyranosyl (1 --> 2)] -beta-D-xylopyranosyl-, 3-O-beta-D-apiosyl(1 --> 3)[alpha-L-rhamnopyranosyl-(1 --> 2)]-beta-D-glucopyranosyl-, 3-O-alpha-L-arabinofuranosyl(1 --> 3)[alpha-L-rhamnopyranosyl-(1 --> 2)]-beta-L-arabinopyranosyl-, 3-O-beta-D-xylopyranosyl(1 --> 3)[alpha-L-rhamnopyranosyl(1 --> 2)]-alpha-L-arabinopyranosyl-, 3-O-beta-D-xylopyranosyl-(1 --> 3)[alpha-L-rhamnopyranosyl(1 --> 2)]-beta-D-glucopyranosyl-, 3-O-beta-D-galactopyranosyl(1 --> 3)[alpha-L-rhamnopyranosyl(1 --> 2)]-beta-D-glucopyranosyl-hederagenins.
