摘要
采用差谱法测定复方甲硝唑片中两组分的含量，甲硝唑和维生素Ｂ６的平均回收率分别为９９．９％和９９．７％。ＲＳＤ分别为０．１４％和０．４３％。方法简便，结果准确。
The analytical principle and method of the absorbance subtraction for two constituents in compound metronidazole tablets were introduced.The average recoveries of metronidazole and vitamin B 6 were 99.9% ( RSD 0.14%) and 99.7% ( RSD 0.43%) respectively.This method is simple and accurate.
