摘要
目的:探索康复灵栓中儿茶的含量测定方法。方法:用迪马钻石ODS C18色谱柱,以0.04mol·L^-1枸橼酸溶液-Ⅳ,Ⅳ二甲基甲酰胺-四氢呋喃(45:8:2)为流动相,检测波长为280nm。结果:儿茶素在0.1487~1.487μg范围内,表儿茶素在0.1081~1.081μg范围内线性关系良好(r=1.000),平均回收率为97.4%(n=6)。结论:用HPLC测定法检测康复灵栓中儿茶含量方法简便,准确可靠。
Objective: An HPLC method for the determination of Catechu in Kangfuling Suppositories was established. Method: A Diamonsil ODS C18 column was used, with the mobile phase of a mixture of 0.04 mol·L^-1 Citric acid, Dimethylformamide and Tetrahydrofuran (45 : 8 : 2 ). The detection wavelength was 280 nm. Results:The calibration curves of Catechin and Epicatechin was linear in the range of 0. 148 7 - 1. 487μg,0. 108 1 - 1.08 1μg ( r = 1. 000), respectively. The average recovery was 97.4%. Conclusion : The method was proved to be specific and reliable.
