To establish a method for chelidonine and chelerythrine in Chelidonium majus . The determination was performed by HPLC using Hypersil ODS 2 (4.6 mm ×200 mm, 5μm).The experimental conditions were as follows:acetonitrile-0.01 mol/L KH2 PO4 water (38∶62, pH=3) as the mobile phase, flow rate:1.0 mL/min, detection wavelength:282 nm, column temperature:35 ℃, the injection volume:20 μL.Results indicated that there was a good linear relationship between the injection volume and area of bond when the injec-tion volume was in the range of 0.25 mg to 1.50 mg.The average results of injection volume recovery was 98.72%,97.34% (n=6),and the RSD was 0.65%,0.86%.This method was sensitive and accurate , with a good repeatability .
