Study of Flavonoids from Potentilla discolor

Hong Lin

Abstract

Objective: To study the chemical constituents of flavonoids from Potentilla discolor.Method: Column chromatography and spectral analysis were used to isolate and identify the constituents.Result: The nBuOH fraction from P.discolor was separated and purified.Seven compounds were obtained and identified as: isorhamnetin(1),quercetin(2),kaempferol(3),kaempferol-3-O-β-D-galactoside(4),kaempferol-3-O-β-Dglucuronide(5),kaempferol-3-O-α-L-arabinoside(6) and mauritianin(7).Conclusion: Compound 3 is isolated from the plant for the first time,Compounds 1,4,6 and 7 are isolated from this genus for the first time.
