吸收比-系数倍率法及其应用——水杨酸钠、安替比林和咖啡因的同时测定

Absorbance Ratio coefficient Multiplication Method and Its Application ——Simultaneous Determination of Sodium Salicylate, Antipyrine and Caffeine

用吸收比－系数倍率法同时测定撒痛风注射液中水杨酸钠、安替比林和咖啡因三组分的含量。它们的回收率分别为１００．７％～１０２．１％、９５．９３％～１０４．５％和９７．５７％～１０１．７％。

In this paper,the simultaneous dertermination of sodium salicylate,antipyrine and caffeine by UV absorbance ratio coefficient multiplication method was suggested.Their recoveries are 100.7%￣102.1%,95.93%￣104.5% and 97.57%￣101.7% respectively.
