Objective: To establish an method for determination of tetrahydropalmatine in Xueshan Jinluohan Zhitong Balm. Method: The tetrahydropalmatine in Xueshan Jinluohan Zhitong Balm was determined by HPLC. CAPCELL PAK C18(4.6 mm×250 mm 5 μm)column was used. The modbile phase was acetonitrile-0.1% phosphoric acid (adjusted pH to 6.0 with triethyplamine) (38∶62) with the flow rate of 1.0 mL·min-1.The column temperature was 30 ℃ and UV detection wavelength was at 280 nm. Result: The tetrahydropalmatine were linear at the range of 0.010 84-0.130 08 μg
respectively. The average recovery was 97.74% and RSD was 1.75%(n=9). Conclusion: The established method is accurate
reliable and specific. The quality of Xueshan Jinluohan Zhitong Balm can be controlled by the method.
