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.
