Two new oleanolic acid‐type triterpenoid saponins, raddeanosides R 22 and R 23 ( 1 and 2 , resp.), together with four known saponins were isolated from the rhizome of Anemone raddeana Regel. The structures of the new compounds were elucidated as oleanolic acid 3‐ O ‐ β ‐ D ‐glucopyranosyl(1→2)[ β ‐ D ‐glucopyranosyl(1→4)]‐ α ‐ L ‐arabinopyranoside ( 1 ) and oleanolic acid 3‐ O ‐ α ‐ L ‐arabinopyranosyl(1→3)‐ α ‐ L ‐rhamnopyranosyl(1→2)[ β ‐ D ‐glucopyranosyl(1→4)]‐ α ‐ L ‐arabinopyranoside ( 2 ). The four known compounds were identified as oleanolic acid 3‐ O ‐ α ‐ L ‐arabinopyranoside ( 3 ), oleanolic acid 3‐ O ‐ β ‐ D ‐glucopyranosyl(1→4)‐ α ‐ L ‐arabinopyranoside ( 4 ), hederasaponin B ( 5 ), and hederacholchiside E ( 6 ) on the basis of chemical and spectral evidences. Compound 4 is reported for the first time from the Anemone genus, while the other three known compounds have been already found in this plant.
