The structures of 1 and 2 were determined as 3-O-alpha-L-rhamnopyranosyl-(1----2)-O-beta-D-glucopyranosyl- (1----2)-alpha-L-arabinopyranosyl oleanolic acid 28-O-alpha-L-rhamnopyranosyl-(1----4)-O-beta-D-glucopyranosyl-(1----6)-b eta-D- glucopyranoside and 3-O-alpha-L-rhamnopyranosyl-(1----2)-O-beta-D-glucopyranosyl-(1----2)-al pha-L- arabinopyranosyl 27-hydroxyoleanolic acid 28-O-alpha-L-rhamnopyranosyl-(1----4)-O-beta-D-glucopyranosyl-(1----6)-b eta-D- glucopyranoside, respectively.
