肤炎宁霜的可见分光光度法测定

Visible Spectrometry Method of Fu Yan Ning Cream

基于肤炎宁在酸性介质中与三价铁离子形成棕黄色复合物，建立了５％肤炎宁霜可见分光光度测定法，用于本品含量及储存后的稳定性分析。方法回收率为１００．３％，相对标准偏差为０．１％。

The stability analytical method of Fu Yan Ning cream containing 5% Bufexamac has been established.The main principle is that bufexamac forms complex with Fe(3+) in acidic medium.The method was simple and accurate.The average recovery was 100.3% with coefficient variation of 0.1%.
