Two New Saponins, Congmuyenosides A and B, from the Leaves of Aralia elata Collected in Heilongjiang, China.

Abstract

Two new triterpenoidal saponins, congmuyenosides A and B, were isolated from the leaves of Aralia elata collected in Heilongjiang Province, China, and established as 3-O-[beta-D-glucopyranosyl(1-->2)][beta-D-glucopyranosyl-(1-->3)]- beta-D-glucopyranosyl hederagenin and 3-O-[beta-D-glucopyranosyl(1-->2))] [beta-D-glucopyranosyl(1-->3)-beta-D-glucopyranosyl(1-->3 )]-beta-D-glucopyranosyl hederagenin, respectively, on the basis of chemical and spectral evidence.
