3-O-(O-alpha-L-rhamnopyranosyl-(1 --> 2)- O-[beta-D-xylopyranosyl-(1 --> 3)]-beta-D-glucopyranoside). The isolated saponins and their derivatives were examined for inhibitory activity on 12-O-tetradecanoylphorbol-13-acetate (TPA)-stimulated 32P-incorporation into phospholipids of HeLa cells as the primary screening test to find new antitumour-promoter compounds.
