  • To established the HPLC method for simultaneously determination of quercitin and quercitrin in Polygonum hydropiper Linn. Methods A VertiSep GES C18 (250 mm ×4.6 mm,5.0 μm)column was adopted with a mobile phase of acetonitrile-0.1% formic acid water(19:81) at the flow rate of 1 ml/min and the column temperature was set at 30℃.The detection wavelength was 350 nm. Results The linear range of quercitin and quercitrin was 4.827~80.455 μg／ml(r=0.999 9, n=5) and 2.934~48.900 μg/ml (r=0.999 7, n=5), respectively, and the average recovery(n=9) was 97.98%,98.29%, RSD was 1.91%,1.84% respectively. Conclusions The method was accurate, simple, reproducible, and could be used to determine the contents of quercitin and quercitrin in Polygonum hydropiper Linn.
