Abstract
The constituents of the 80% ethanol extract of the whole plant of Potentilla discolor Bung.were isolated and purified by various chromatographic methods.The structures were confirmed on the basis of physic-chemical properties and spectroscopic data.Five compounds were isolated and identified as(6S,9R)-roseoside(1),caffeic acid(2),γ-linolenic acid(3),tetracosanoic acid(4),ethyl gallate(5).Compounds 1-5 have been isolated from this plant for the first time.
