Abstract:Objective: To establish an HPLC method for determination of tetrahydropalmatine in Fufang Zaoren Capsules. Method : Diamonsil C18 column (4. 6 mm × 150 mm, 5 μm)was used. The mobile phase was methanol-0. 1% phosphoric acid solution (55:45 ). The flow rate was 1.0 mL . min-1. The detection wavelength was 280 nm. Results : Tetrahydropalmatine had a good linear relationship between 0. 060 4 -0. 544 0 μg, average recovery was 99.44%, RSD was 2.00%. Conclusion: This method was rapid, simple, and accu- rate, can be used for the determination of tetrahydropalmatine.
Keywords:Fufang Zaoren Capsules  Tetrahydropalmatine  HPLC
