Abstract:
OBJECTIVETo investigate the chemical constituents of Potentilla chinensis.
METHODSilica 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.
RESULTSix 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.
