Abstract
Seven new oleanane-type saponins, named araliasaponins XII-XVIII, were isolated from the roots of Aralia chinensis, together with 14 known triterpene saponins. On the basis of the chemical and spectroscopic evidence, the structures of these new saponins were elucidated as follows: 3-O-beta-D-glucopyranosyl(1-->3)-[beta-D -glucopyranosyl(1-->2)]-alpha-L-arabinopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl ester, 3-O-beta-D-glucopyranosyl(1-->3)-[beta-D-xylopyranosyl (1-->2)]-alpha-L-arabinopyranosyl oleanolic acid 28-O-alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl (1-->6)-beta-D-glucopyranosyl ester, 3-O-beta-D -glucopyranosyl(1-->3)-[beta-D-galactopyranosyl(1-->2)] -beta-D-glucopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl ester, 3-O-beta-D-glucopyranosyl(1-->3)-[beta-D -xylopyranosyl(1-->2)]-beta-D-glucopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl (1-->6)-beta-D-glucopyranosyl ester, 3-O-beta-D -glucopyranosyl(1-->3)-[beta-D-galactopyranosyl (1-->2)]-beta-D-galactopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl ester, 3-O-alpha-L -arabinofuranosyl(1-->4)-[beta-D-glucopyranosyl (1-->2)]-beta-D-glucuronopyranosyl oleanolic acid dimethyl ester and 3-O-alpha-L-arabinofuranosyl (1-->4)-[beta-D-glucopyranosyl(1-->2)]-beta-D -glucuronopyranosyl oleanolic acid 28-O-beta-D -glucopyranosyl(1-->6)-beta-D-glucopyranosyl methyl ester, respectively.Entities:
