摘要
A new triterpenoid saponin, anemoside A, was isolated from Anemone rivularis Buch. Ham. ex DC. Its structure was elucidated as 3 O [β D ribopyranosyl(1→3) α L rhamnopyranosyl(1→2) α L arabinopyranosyl] oleanolic acid 28 O α L rhamnopyranosyl(1→4) β D glucopyranoside by means of chemical methods and 1H NMR, 13 C NMR, DEPT, MS spectral analyses.
