Objective:To determine the content of psoralen in Gongyanping Tablet.Methods:A RP-HPLC method was developed.The chromatographic column was Diamonsil-C18.The mobile phase was methanol-water(50∶50).The flow rate was 1.0mL·min-1
and the detection wavelength was 246 nm.Results: The average recovery for psoralen was 99.9%.precision of the method was 2.0%(RSD
n=6).Conclusion:The method can be used for quantitative determination of psoralen in Gongyanping tablets.
