Abstract: Objective To establish a HPLC method for determination of silybin contents in Gan'an capsule. Methods Angilent Zorbax SB C18(4.6 mm×250 mm, 5 μm) column was used with 1% acetic acid:methanol=50:50 as the mobile phase. The flow rate was 1.0 ml/min, and the temperature was at 30℃.The detection wavelength was 287 nm.Determination of silybin contents in Gan'an capsule of 10 batches of preparations. Results The silybin calibration curve was at the range of 10.28~123.36 μg/ml(r=1)with average recovery of 97.00%(RSD=0.68%).10 batches of preparations silybin contents in Gan'an capsule was 11.11~16.65 mg/granule. Conclusion The method was simple accurate and reproducible which could be used for the quality control of Gan'an capsule.
