摘要
Five new oleanolic acid glycosides, tarasaponins III-VII, were isolated from the dried root-bark of Aralia elata together with stipuleanoside R(2), in addition to eight saponins previously reported. They were characterized as oleanolic acid 3-O-[beta-D-xylopyranosyl(1 --> 2)][beta-D-glucopyranosyl(1 --> 3)]-alpha-L-arabinopyranoside, beta-D-glucopyranosyl oleanolate 3-O-[beta-D-glucopyranosyl(1 --> 2)][alpha-L-arabinofuranosyl(1 --> 4)]-beta-D-glucuronopyranoside, beta-D-glucopyranosyl oleanolate 3-O-[beta-D-xylopyranosyl(1 --> 2)][beta-D-glucopyranosyl(1 --> 3)]-beta-D-glucuronopyranoside, beta-D-glucopyranosyl oleanolate 3-O-[beta-D-xylopyranosyl(1 --> 2)][beta-D-galactopyranosyl(1 --> 3)]-beta-D-glucuronopyranoside, beta-D-glucopyranosyl oleanolate 3-O-[beta-D-xylopyranosyl(1 --> 2)][beta-D-glucopyranosyl(1 --> 3)-alpha-L-arabinopyranoside, respectively.
