- W2348338209 abstract "Objective To establish an HPLC method for the determination of quercetin and kaempferol in Polygonum perfoliatum L.Methods HPLC was used to quantitative analysis. The Kromasil C 18 column(5μm,250×4.6mm) was used,and mobile phase was composed of methanol-0.4%H 3 PO 4 /Water(60:40). Detection wavelength was at 360 nm at 30℃. Results The quercetin and kaempferol's average recovery were 99.6% and 100.8%,respectively. Linear range of methods was 0.158 9~3.178μg and 0.006 99~0.279 6μg, respectively.Conclusion The result is accurate and the reproducibility is good. The method can be used for quality control of Polygonum perfoliatum L." @default.
