摘要(Abstract):
目的制定和胃胶囊中延胡索乙素的含量测定方法,以更好的控制产品质量。方法采用HPLC进行测定,色谱柱为Hypersil BDS C18(5μm,4.6 mm×150 mm);流动相为甲醇-0.1%磷酸(用三乙胺调节pH至6.0)(60∶40);检测波长为280nm。结果和胃胶囊中延胡索乙素的线性范围为0.104~0.728μg,r=0.9997,平均回收率为98.95%。结论该方法操作简单、重现性好、专属性高,可作为和胃胶囊含量测定的指标。
Objective To establish the determination method of Tetrahydropalmatine in Hewei Jiaonang.Method The HPLC method for Tetrahydropalmatine was used.Column:Hypersil BDS-C_(18)(5 μm,4.6 mm×150 mm),mobile phase:methanol:0.1% H_3PO_4(60∶40).It was detected at 280 nm.Result The linear range of Tetrahydropalmatine was 0.104~0.728 μg,r=0.9997,The mean recovery was 98.95%.Conclusion This method is simple and accurate with good reproducibility.The method could be applied to determine Tetrahydropalmatine in Hewei Jiaonang.
