[Studies on triterpenoids from Potentilla chinensis].
OBJECTIVE
To investigate the chemical constituents of Potentilla chinensis.


METHODS
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.


RESULTS
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.
