Two unusual oleanane saponins from Anemone anhuiensis.
From the rhizomes of Anemone anhuiensis (Ranunculaceae), two new triterpene saponins, anhuienosides A (1) and B (2), were isolated. These compounds are glycosylated at C-23 and their structures were elucidated as hederagenin 23-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranoside (1) and 23-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl hederagenin 28-O-alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl ester (2) on the basis of chemical and spectral evidence.
