| Abstract: | OBJECTIVE: Determination of tetrahydropalmatine in Rhizoma Corydalis. METHODS: A non-aqueous capillary electrophoresis method was set up.The effect of organic solvent and the concentration of acetic acid in buffer separation was studied. RESULTS: The method was linear in range of 540g/ml of tetrahydropalmatine and good precision was also obtained.The content of tetrahydropalmatine in Rhizoma Corydalis was determined with no pre-treatment. CONCLUSION: The established method was accurate,rapid and simple. |
