AIM To investigate the chemical constituents of the rhizome of Anemone raddeana Regel, so as to find new active compounds. METHODS The ethanol extracts of the rhizome of Anemone raddeana were obtained by sil ica column, HPLC. The structures of the compounds were elucidated by means of ph ysico chemical method and spectral analysis (IR, FAB MS, 1HNMR, 13 CNMR, DEPT, 1H 1H COSY, HMQC, HMBC). RESULTS Nine compounds were isolated and identified as 27 hydroxyolean 12(13) en 28 oic acid 3 O α L rhamnopyranosyl (1→2) α L arabinopyra noside (1), eleutheroside K (2), Oleanolic acid 3 O α L rhamnop yranosyl (1→2) [β D glucopyranosyl (1→4)] α L arabinopyran oside (3), betulin (4), betulic acid (5), acetyloleamolic acid (6), evonymitol (7), oleamolic acid (8) and diosgenin (9). CONCLUSION Compound 1 is a new compound, named raddeanoside 12. Comp ounds 3～7 were isolated from this plant for the first time.
