Abstract:
OBJECTIVE:To establish a method for simultaneous determination of pulchinenoside B4,caffeic acid,baicalin, palmatine hydrochloride and berberine hydrochloride in Baipuhuang tablets. METHODS:HPLC method was adopted. The determi-nation of Agela Technologies Venusil XBP C18(L)with mobile phase consisted of acetonitrile-0.05 mol/L monopotassium phosphate (gradient elution)at the flow rate of 0.8 mL/min. The detection wavelengths were set at 203 nm(pulchinenoside B4)and 323 nm (caffeic acid,baicalin,palmatine hydrochloride,berberine hydrochloride). The column temperature was set at 30 ℃,and the sam-ple size was 10 μL. RESULTS:The linear ranges were 0.08141-8.141μg for pulchinenoside B4(r=0.9998),0.01871-1.871 μg for caffeic acid (r=0.9994),0.03733-3.733 μg for baicalin (r=0.9992),0.02885-2.885 μg for palmatine hydrochloride (r=0.9996) and 0.02758-2.758 μg for berberine hydrochloride (r=0.9997). The limits of quantitation were 0.009,0.006,0.008, 0.011,0.013 ng,respectively. The limits of detection were 0.030,0.020,0.025,0.034,0.036 ng,respectively. RSDs of preci-sion,stability and reproducibility tests were all lower than 2.0%. The average recoveries were 97.39%-102.34%(RSD=1.81%,n=6),96.77%-98.92%(RSD=0.85%,n=6),97.38%-103.72%(RSD=2.46%,n=6),96.73%-102.01%(RSD=2.22%,n=6)and 96.47%-101.07%(RSD=1.61%,n=6),respectively. CONCLUSIONS:The method is simple,accurate and reproducibility,and can be used for simultaneous determination of pulchinenoside B4,caffeic acid,baicalin,palmatine hydrochloride and berberine hy-drochloride in Baipuhuang tablet.
