| Abstract:Objective To establish a HPLC method for tetrahydropalmatine in Lianlian capsule. Method The determination method of Lianlian capsule was carried out by HPLC, which quantitative index was represented with tetrahydropalmatine. Result The calibration curves was linear in the rage of 7.908~158.06 μg/ml for tetrahydropalmatine. The average recovery was 96.18 %(RSD 1.2%).Conclusion The method was exclusive, accurate and reliable, which could be used for improvement of quality control in Lianlian capsule. |
