Seven new oleanane-type and four new ursane-type triterpene saponins, named araliasaponins I-XI were isolated from the roots of Aralia decaisneana, together with four known triterpene saponins. On the basis of the chemical and spectroscopic evidence, the structures of these new saponins were elucidated as follows: 3-O-β-D-xylopyranosyl-(1 → 3)-β-D-glucopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 2)]-α-L-arabinopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl ester, 3-O-β-D-glucopyranosyl-(1 → 3)-α-L-arabinopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranosyl ester, 3-O-β-D-glucopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 2)]-α-L-arabinopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranosyl ester, 3-O-β-D-glucopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 2)-β-D-glucopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl ester, 3-O-β-D-glucopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 2)]-β-D-galactopyranosyl oleanolic acid, 3-O-β-D-glucopyranosyl(1 → 3)-[β-D-xylopyranosyl-(1 → 2)]-β-D-galactopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl ester, 3-O-β-D-glucopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 2)]-β-D-galactopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl(1 → 6)-β-D-glucopyranosyl ester, 3-O-β-D-glucopyranosyl-(1 → 3)-β-D-xylopyranosyl-(1 → 2)-α-L-arabinopyranosyl ursolic acid 28-O-β-D-glucopyranosyl ester, 3-O-β-D-glucopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 2)]-α-L-arabinopyranosyl ursolic acid, 3-O-β-D-glucopyranosyl-(1 → 3)-α-L-arabinopyranosyl ursolic acid 28- O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranosyl ester and 3-O-β-D-glucopyranosyl-(1 → 3)-(β-D-xylopyranosyl-(1 → 2)]-β-D-glucopyranosyl ursolic acid 28-O-β-D-glucopyranosyl ester.
