Two new triterpenoid saponins from Sarcandra glabra.
Two new triterpenoid saponins, named sarcandroside A and B, have been isolated from Sarcandra glabra (Thunb) Nakai. Their structures have been established as 3beta,19alpha,20beta-trihydroxyurs-11,13 (18)-diene-28,20beta-lactone-3-O-beta-D-glucopyranosyl (1 --> 3)-[alpha-L-rhamnopyranosyl(1 --> 2)]-beta-D-xylopyranoside (1) and 3-O-beta-D-glucopyranosyl (1 --> 3)-[alpha-L-rhamnopyranosyl(1 --> 2)]-beta-D-xylopyranosyl-pomolic acid 28-O-beta-D-glucopyranosyl ester (2) by means of spectral and chemical methods.
