Objective:To establish an HPLC method for the determination of tetrahydropalmatine in Xiaoheling capsule.Method:The HPLC separation was performed on C18 column(4.6 mm × 150 mm
5 μm) with mobile phase consisted of acetonitrile-2% acetic acid solution(ajusted pH to 5.0 using triethylamine)(25∶ 75);The detective wavelength was set at 280 nm with a flow rate of 1 mL.min-1and the column temperature was set at 30 ℃.Result: Corydalis was linear in the range of 44.68-357.44 mg.L-1 with coefficient 0.999 9.Average recovery was 101.10% with RSD 2.42%(n = 5).Conclusion: The method was simple
rapid and accurate
and applicable for the quality control of Xiaoheling capsule.
