摘要
目的建立HPLC法测定黄连上清胶囊中盐酸小檗碱的含量。方法高效液相色谱法,分析色谱柱LanboYWG—C18(150mm*4.6mm,5um),流动相为乙腈-0.1%磷酸溶液(58:42)(每100ml中加入十二烷基磺酸钠0.1g),检测波长为246nm。结果测得盐酸小檗碱在0.257~1.285mg/ml内呈线性.平均回收率为99.4%,RSD=0.93%.结论:该法操作简便,准确。
Objective: To establish a method for the determination of berberine hydrochloride in huanglian shangqing capsules . Methods: High performance liquid chromatography; station phase: LanboYWG-C1 ( 150mm*4.6mm, 5um)colunm; mobile phase: acetonitrile-0.1%phosphate acid (58: 42) (0.1g sodium dodecyl sulfate in 100ml 0.1%phosphate acid ), detecting wavelength : 246nm .Result: The linger range of psoralen concentration was 0.257 - 1.285 mg/ml ; the average recovery of the assay was 99.4%, and RSD =0.93%. Conclusion : This method is simple and convenient. It can be used to control the quality of huanglian shangqing capsules.
