摘要
Ten compounds were obtained from the 90% ethanol extract of whole plant of Potentilla discolor Bunge.On the basis of physicochemical properties and spectral data,these compounds are identified as follows: oleanolic acid(Ⅰ),kaempferol-7-O-α-L-rhamnoside(Ⅱ),quercetin-7-O-α-L-rhamnoside(Ⅲ),2α,3α-dihydroxyolean-12-ene-28-acid(Ⅳ),brevifolin(Ⅴ),ellagic acid-3,3′-dimethyl ether-4-O-β-D-glucopyranoside(Ⅵ),ellagic acid-3-methyl ether-4′-O-α-rhamnopyranoside(Ⅶ),2α-hydroxy-betulinic acid(Ⅷ),sitosterol(Ⅸ) and daucosterol(Ⅹ).In which,compound Ⅱ,Ⅲ and Ⅴ are isolated from genus Potentilla L.for the first time,and compound Ⅳ is isolated from P.discolor for the first time.
