摘要
目的:不经分离直接测定中胃康胶囊中盐酸小檗碱的含量。方法:用TU-1901双光束紫外可见分光光度计采集吸收度信息,并通过数据转换将信息转到褶合光谱程序中,并由该程序单组分定量分析系统计算盐酸小檗碱的含量。结果:盐酸小檗碱的平均回收率和RSD分别为100.00％,0.03％。结论:本方法结果可靠、快速准确,可有效控制本品的质量。
OBJECTIVE: To determine berberine hydrochoride in Zhongweikan capsules without separation. METHODS: The absorption data was measured by the UV - VIS spectrophotometer, the convolution spectrometry method was used to calculate the concentration of berberine hydrochoride after absorption data transformation. RESULTS : The average recovery and RSD of berberine hydrocholoride were as follows; 100. 00% 0. 03% . CONCLUSION : Convolution spectrometry is reliable, accurate and suitable for the determination of the drug contents in hospital preparations.
