文摘Two new oleanane triterpene saponins, named as anhuienside C (1) and D (2), were isolated from the rhizomes of Anemone anhuiensis (Ranunculaceae). The structures of the new compounds were elucidated as 3-O-alpha-L-rhamnopyranosyl (1-->2)-beta-D-xylopyranosyl oleanolic acid 28-O-beta-D-glucopyranosyl (1-->6)-beta-D-glucopyranosyl ester (1) and 3-O-beta-D-xylopyranosyl oleanolic acid 28-O-alpha-L-rhamnopyranosyl (1-->4)-beta-D-glucopyranosyl (1-->6)-beta-D-glucopyranosyl ester (2), respectively.
