Abstract:
Objective: A capillary electrophoresis for the determination of berberine hydrochloride and palmatine hydrochloride in Ruyijinhuang Powder(Rhizoma Curcumae Longae, Radix et Rhizome Rhei, Cortex Phellodendri, Rhizoma Atractylodis, etc.) was established. Methods: The berberine hydrochloride and palmatine hydrochloride were determined using benzoic acid as an internal standard its detection wavelength was at 230nm. The optimized condition was achieved with a fused\|silica capillary 100?m?56.5cm, 10mmol?L -1 phosphate buffer(pH=4.80) containing 30% acetonitrile, a constant voltage of 20kv and temperature at 30℃. Results: Calibration curve was constructed in the range of 5?g?mL -1 ～100?g?mL -1 for berberine hydrochloride and palmatine hydrochloride, respectively. The regression equations were Y=0.02964X -0.00771 ( r =0.9998) and Y =0.01092 X -0.02939 ( r =0.9997) for berberine hydrochloride and palmatine hydrochloride, respectively. The average recovery was 98.7% and 102.1%( n =5), respectively. Conclusion: This method is sample, quick and sensitive.
