Abstract

AIM:To study the flavones from Potentilla discolor Bunge.METHODS:Extracted with 70% ethyl alcohol,the constituents were isolated by Chromatography of silica gel,Sephadex LH-20 and ODS and their structures were identified on the basis of the physical properties and spectral analysis.RESULTS:Nine flavanoids were isolated from Potentilla discolor Bunge and identified as quercetin(1),kaempferol(2),quercetin-3-O-α-L-rhamnpyranoside(3),quercetin-3-O-β-D-glucopyranoside(4),quercetin-3-O-α-D-arabinfuranoside(5),rutin(6),quercetin-3-O-β-D-glucuronide(7),kaempferol-3-O-β-D-glucuronide(8),quercetin3-O-β-D-galactoside-7-O-β-D-glucoside(9).CONCLUSION:Compounds 4-7 were obtained from this plant for the first time and compounds 8 and 9 were isolated from this genus for the first time.
