ABSTRACT
Objective To establish a method for the determination of berberine hydrochloride and phellodendrine in Lishukang Capsules by HPLC. Methods Waters Symmetry C18 column (4.6 mm× 250 mm, 5μm) was used, the mobile phase was acetonitrile-0.1%phosphoric acid (0.1 g sodidum dodecyl sulfonate in 100 mL water), with the flow rate of 1 mL/min by gradient elution. The detection wavelength was set at 284 nm. Results Berberine hydrochloride showed good linear relationship (r 2=0.999 1) in the range of 403.4-10 084.7 μg, the average recovery rate was 99.8%(RSD=1.7%). Phellodendrine showed good linear relationship (r 2=0.999 2) in the range of 169.137 6-4228.44 μg, the average recovery rate was 95.5%(RSD=3.2%). Conclusion The method is specific, accurate and convenient to be used for the quality control of Lishukang Capsules.
