OBJECTIVE: To investigate the chemical constituents of Potentilla chinensis. METHOD: Silica gel column chromatography and Sephadex LH - 20 gel column chromatography were employed for the isolation and purfication. The structures were identified on the basis of spectral data and chemical evidence. RESULT: Six compounds were isolated and identified as follows: 3-hydroxy-11-ursen-28, 13-olide, 11, 12-dehydroursolic acid lactone (1), 3-O-acetyl pomolic acid (2), betulinic acid (3), 3-oxo-12-ursen-28-oic acid (4), ursolic acid (5), oleanic acid (6). CONCLOUSION: All these compounds were isolated from P. chinensis for the first time, compound 1, 2, 4 were isolated from this genus for the first time.
