Abstract:Objective To establishan HPLC method for simultaneous determinationofberberine hydrochloride,epiberberine, coptisine hydrochloride and palmatine hydrochloride in Huanglian Capsules.Methods CAPCELL PAK C18 chromatographic column ( 250mm×4.6mm , 5μm )was used. The mobile phase was acetonitrile -0.05mol/L potassium dihydrogen phosphate solution (45:55),isocratic elution,flow rate 1.0mL/min ,detection wavelength 345nm ,column temperature 30qC ,injection volume:10 (20 μL .ResultsBerberinehydrochloride,epiberberine hydrohloride,coptisinehydrochlorideandpalmatinehydrochloridehadgoodlinear relationship with the peak area in the linear ranges of 3.9041-23.4480μg/mL ,0.3644 -2.1888 μg/mL, 0.6711-4.0304μg/ mLand 0.8502-5.1064μg/mL ,respectively. The average recoveries were 99.61% 98.39% ,98.84 % , 99.04% ,and the RSDs were 0.19 % ,1.21 % ,0.78 % , 0.53% ( n=6 ),respectively. Conclusion The method is efficient,accurate and sensitive, andcanbeusedforthesimultaneousdetermiationofberberinehydrochloride,epiberberine,coptisinehydrochlorideandpalmatine hydrochloride inHuanglian Capsules,which providesascientific basis forbetercontrolofthequalityofHuanglian Capsules.
