Eleven triterpenoidal saponins having oleanolic acid or hederagenin as the aglycone and two flavonoidal glycosides were isolated from the leaves of Aralia elata SEEM. (Araliaceae). The structures of four new saponins (1,2,3,and 4) were established to be 3-O-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranosyl-hederagenin 28-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranosyl ester, 3-O-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranosyl-oleanolic acid 28-O-β-D-xylopyranosyl(1→6)-β-D-glucopyranosyl ester, 3-O-β-D-glucopyranosyl(1→3)-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranosyl-hederagenin 28-O-β-D-glucopyranosyl(1→6)-β-D-glucopyranosyl ester, and 3-O-β-D-glucopyranosyl(1→3)-α-L-rhamnopyranosyl(1→2)-α-L arabinopyranosyl-hederagenin, respectively, on the basis of spectroscopic and chemical evidence.
