摘要
目的:建立不经分离同时测定地塞米松磷酸钠及干扰组分尼泊金乙酯含量的测定方法。方法:以蒸馏水为空白,采用褶合光谱法。结果:平均回收率为1008%,9939%;RSD为100%,061%。结论:本法方便准确,适用于紫外吸收有干扰的多组分制剂的常规分析。
OBJECTIVE: To simultaneous
determine the main-component dexamethasone sodium phosphate and the
interfering-component ethylparaben in compound dexamethasone sodium phosphate eye drops
without separation. METHODS: A convolution spectrometry method has been applied.
RESULTS: The average recoveris and relative standard deviation were
100.8%,10%;9939%,061%,respectively. CONCLUSION: This method is convenient,accuracy and
suitable for routine analysis of multicomponent preparation which has interference in ultraviolet
spectrum.
