Abstract

Two new 27-hydroxy-oleanolic acid type triterpenoid saponins, raddeanoside 20 (1) and raddeanoside 21(2) were isolated from the rhizome of Anemone raddeana Regel. The structures of the two compounds were elucidated as 27-hydroxy-oleanolic acid 3-O-alpha-L-rhamnopyranosyl(1-->2) [beta-D-glucopyranosyl (1-->4)]-alpha-L-arabinopyranoside (1) and 3-O-alpha-L-rhamnopyranosyl (1-->2)-alpha-L-arabinopyranosyl-27-hydroxy-oleanolic acid 28-O-alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl (1-->6)-beta-D-glucopyranoside (2) on the basis of chemical and spectral evidence.
