摘要：

Four new triterpene saponins, asteryunnanosides A, B, C and D, have been isolated from Aster yunnanensis and their structures deduced as 2 alpha,3 beta,23-trihydroxyolean-12-en-28-oic acid-28-O-alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranoside, 2 alpha, 3 beta,23-trihydroxyolean-12-en-28-oic acid-28-O-beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranoside, 2 alpha,3 beta-dihydroxyolean-12-en-28-oic acid-28-O-alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranoside and 2 alpha,3 beta-dihydroxyolean-12-en-28-oic acid-28-O-beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranoside, respectively, by means of spectral and chemical data.
