摘要: ]目的:建立头孢丙烯干混悬剂溶出度的测定方法。方法:以十八烷基硅烷键合硅胶为填充剂[Luna C18(2) 100A,4.6 mm×150 mm,5 μm];以磷酸二氢铵溶液(取磷酸二氢铵20.7 g,加水1 800 mL使溶解,用磷酸调节pH值至4.4)-乙腈(90∶10)为流动相;检测波长为280 nm,柱温为25 ℃,采用HPLC法测定头孢丙烯含量;以纯化水为溶出介质,桨法25 r·min-1,测定头孢丙烯的溶出,并对溶出测定方法学进行验证。结果:头孢丙烯干混悬剂溶出方法专属性、线性关系、精密度、回收率等良好。结论:本方法能准确的测定头孢丙烯干混悬剂的溶出度。

Abstract: Objective:To establish a method for the determination of the dissolution of Cefprozil for Suspension. Methods: Cefprozil content was detected by HPLC and on Kromasil C18 column with mobile phase of ammonium dihydrogen phosphate solution(Take 20.7 g of ammonium dihydrogen phosphate, add 1 800 mL of water to dissolve, adjust the pH to 4.4 with phosphoric acid)- Acetonitrile(90∶10) and detected at 280 nm, column temperature of 25 ℃. The dissolution of Cefprozil for Suspension was measured by slurry method 25RPM in water. Results: The dissolution of Cefprozil for Suspension was good on specificity, linearity, precision and recovery etc. Conclusion: The method can accurately determine the dissolution of Cefprozil for Suspension.
