Abstract
Two new hopane-type saponins, succulentosides A and B, were isolated f rom Polycarpon succulentum (whole plant). Based on spectral analyses ( including 2D NMR, and FAB-mass spectroscopy), the structures of succul entosides A and B were characterized as 6 L-arabinopyranosyl]-beta-O-b eta-D-xylopyranosyl-16 beta-O-beta-D xylopyranosyl-22-hydroxyhopane, a nd 6 alpha-O-alpha-L-arabinopyranosyl-3 beta-O-beta-D-xylopyranosyl-16 beta-O-beta-D-xylopyranosyl-22-hydroxyhopane, respectively.
