摘要
用三波长分光光度法,不经分离可同时测定复方头孢氨苄胶囊中头孢氧苄和甲氧苄啶的含量。本法取样少,操作简迅,结果准确。两者的回收率分别为.100.28%和99.94%,变异系数为0.65%和0.49%。
Cephalexin(CEX)and trimethoprim(TMP)in compound cephalexincapsules were determined simultaneously using tri-wavelength UV spectrophoto-metry,without separation.The recoveries and cv values of CEX and TMP were100.28%,99.94% and 0.65%,0.49% respectively.The method is simple,rapidand accurate.
