Isolation and identification of chemical constituents from whole plant of Potentilla multicaulis Bunge.

Objective To study the chemical constituents of whole plant of Potentilla multicaulis Bunge.Methods The constituents of the 70% ethanol extract of the whole plant of Potentilla multicaulis Bunge.were isolated and purified by various chromatographic methods.The structures were confirmed on the basis of physico-chemical properties and spectroscopic data.Results Seven compounds were isolated and identified as gallic acid(1),oleanolic acid(2),quercetin(3),2-pyrrolidone(4),1H-azepine-2,4(3H,5H)-dione,dihydro-(5),β-sitosterol(6),β-daucosterol(7).Conclusions Compounds 4 and 5 are isolated from Potentilla for the first time;compouds 17 are isolated from this plant for the first time.
