Abstract

Objective To study the chemical constituents of Potentilla discolor.Methods Chemical constituents were isolated by repeated column chromatographies.The structures were elucidated on the basis of spectral data analysis.Results Sis compounds,pomolic acid(1),3-O-acetyl-pomolic acid(2),oleanolic acid(3),2α-hydroxyl betulinic acid(4),quercetin-3-O-β-D-glucoside(5),kaempferol-3-O-β-D-glucoside(6) were isolated from P.discolor.Conclusion All the compounds were isolated from the plant for the first time.
