Pharmaceutical Journal of Chinese People's Liberation Army(2014)
Abstract
目的:用HPLC法同时测定复方氯已定含漱液中葡萄糖酸氯已定和甲硝唑的含量。方法采用Agela Tech-nologies C18(250 mm×4.6 mm,5μm)为色谱柱;以乙腈:磷酸-三乙胺缓冲液(pH为3.2,15:85)为流动相;检测波长为280 nm,流速1.0 ml·min-1。结果甲硝唑、葡萄糖酸氯已定回收率分别为97.05%、98.41%,RSD分别为0.59%、1.89%( n =9)。结论本方法快捷、简便、灵敏,可作为该制剂质量控制的有效方法。
