TITLE:
摘要: 目的:建立测定风湿祛痛胶囊中盐酸小檗碱含量和溶出度的方法。方法:采用高效液相色谱法测定制剂中盐酸小檗碱的含量:色谱柱为Waters Xbridge C18,流动相为乙腈-0.05 mol/L磷酸二氢钠缓冲液(45 ∶ 55,V/V),流速为0.5 ml/min,检测波长为345 nm,柱温为30 ℃,进样量为10 μl。采用转篮法测定盐酸小檗碱的溶出度。结果:盐酸小檗碱检测质量浓度线性范围为1.06~74.2 μg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<1%;加样回收率为96.8%~100.6%(RSD=1.6%,n=9)。样品30 min的溶出度均>80%。结论:该方法操作简便、稳定、重复性好,可用于风湿祛痛胶囊中盐酸小檗碱含量和溶出度的测定。
ABSTRACT: OBJECTIVE:To establish a method for content and dissolution determination of berberine hydrochloride in Fengshi qutong capsule. METHODS:HPLC was conducted to determine the content of berberine hydrochloride in the preparation: the column was Waters Xbridge C18 with mobile phase of acetonitrile-0.05 mol/L sodium hydrogen (45 ∶ 55,V/V) at a flow rate of 0.5 ml/min, detection wavelength was 345 nm, column temperature was 30 ℃, and the injection volume was 10 μl. Rotating basket method was used to determine the dissolution of berberine hydrochloride. RESULTS:The linear range of berberine hydrochloride was 1.06-74.2 μg/ml(r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 1%; recovery was 96.8%-100.6% (RSD=1.6%,n=9). The dissolution of samples in 30 min was higher than 80%. CONCLUSIONS: The method is simple and stable with good reproducibility, and can be used for content and dissolution determination of berberine hydrochloride in Fengshi qutong capsule.
