A novel prosapogenin (3) was obtained on the alkaline hydrolysis of 1 and its structure defined as 3-O-[beta-D-glucopyranosyl (1-->4)-beta-D-glucopyranosyl(1-->3)-alpha-L-rhamnopyranosy (1-->2)-beta-D-xylopyranosyl]hederagenin. The structures of compounds 1-3 were established by spectral and chemical methods.en10.1021/np960193xinfo:eu-repo/semantics/closedAccessArticle594415418WOS:A1996UR601000178699185Q1N/A
