Objective To develop a high performance liquid chromatograph method for determination of gentiopicrin in Fuzhengpingxiao capsule which could be used as a quality control indicator. Methods The separation was performed by 1100 series high performance liquid chromatograph, on an Agilent Zorbax XDB-C₈ column (4.6 mm×150 mm, 5 μm),using the methanol-water (19:81) as the mobile phase, and the analysis was detected by UV spectrometry at 275 nm with flowing rate at 1 ml/min, the column tempreture was 25 ℃. Results He correlation coefficient of the calibration curve was better than 1 in the range 4.88~97.60 μg/ml and the calibration curve was Y=23.82X－7.170. The relative standard deviation(RSD) of day to day precision was less than 3% and within-day precision was less than 2%. The lowest limit of quantification was 0.244 μg/ml.The sample recovery of Fuzhengpingxiao capsule was 99.39%. Conclusions This quantitative assay with better specificity, higher sensibility and could be used to determinate gentiopicrin in Fuzhengpingxiao capsule.
