Two new triterpenoid saponins, named hupehensis saponin F and G, were isolated from the water soluble part of Anemone hupehensis Lemoine. By chemical and spectroscopic evidence, their structures were elucidated as 3-O-beta-D-ribopyranosyl(1-->3)-alpha-L-rhamnopyranosyl(1--> 2)-alpha-L-arabinopyranosyl hederagennin-28-O-alpha-rhamnopyranosyl(1--> 4)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl(1--> 3)-alpha-L-rhamnopyranosyl(1-->4)-beta-glucopyranosyl(1--> 6)-beta-D-glucopyranoside and 3-O-beta-D-ribopyranosyl(1-->3)-alpha-L-rhamnopyranosyl(1--> 2)-alpha-L-arabinopyranosyl hederagenin-28-O-beta-glucopyranosyl(1-->3)-alpha-rhamnopyranosyl( 1--> 4)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl(1--> 3)-alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl(1--> 6)-beta-D-glucopyranoside, respectively.
