    ABSTRACT: Two new triterpenoid saponins, biondianosides F and G, together with 13 known compounds, were isolated from the ethanolic extract of the roots of Biondiachinensis Schltr. (Asclepiadaceae). Their structures were characterized as 3-O-beta-D-glucopyranosyl-2alpha,3beta-dihydroxyurs-12-en-28-oic acid-beta-D-glucopyranosyl-(1-->2)-[beta-D-glucopyranosyl-(1-->6)]-beta-D-glucopyranosyl ester (biondianoside F) and 3-O-beta-D-glucopyranosyl-2alpha,3beta,23-trihydroxyolean-12-en-28-oic acid-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl ester (biondianoside G) by spectral and chemical evidence.
