Abstract: Four new saponins were isolated from the leaves of Oplopanax elatus Nakai.The structures of the four saponins, tentatively named compounds A(1), B(2), C(3) and D (4) were elucidated to be 28-O-a-L-rhamnopyranosyl (1-4)-β-D-glu-copyranosyl (1-6)-β-D-glucopyranosyl esters of betulinic acid 3-O-β-D-glucopyra-noside (1) .oleanolic acid 3-O-β-D-glucopyranoside (2), 3a, 23-dihydroxyolean-12-ene-28-Oic acid (= 3-epi-hederagenin) (3), 3β-hydroxyolean-12-ene-23-al-28-oic acid (=gypsogenin) (4), respetively.
