Abstract
Two new 27-hydroxyoleanolic acid-type triterpenoid saponins, raddeanoside Ra (1) and raddeanoside Rb (2), were isolated from the rhizome of Anemone raddeana Regel. The structures of the two compounds were elucidated to be 27-hydroxyoleanolic acid 3-O-beta-D: -glucopyranosyl-(1 --> 4)-alpha-L: -arabinopyranoside (1) and 27-hydroxyoleanolic acid 3-O-alpha-L: -arabinopyranosyl-(1 --> 3)-alpha-L: -rhamnopyranosyl-(1 --> 2)-alpha- L: -arabinopyranoside (2) on the basis of chemical and spectral evidence.
