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- α- L- rhamnopyranosyl (1 → 2 )- β- D-xylopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl (1→6)-β-D-glucopyranosyl ester (1) and 3-O-β-D-xylopyranosyl oleanolic acid 28 - O-α-L -rhamnopyranosyl (1→4) - β -D-glucopyranosyl (1 → 6) -β-D-glucopyranosyl ester (2), respectively.
