摘　　要：用乘子罚函数法处理多波长分光光度数据同时测定复方阿斯匹林片中三组分的含量 ,模拟样品中阿斯匹林、非那西丁、咖啡因的平均回收率分别为 10 0 .4 %、99.78%、10 0 .6% ,相对标准偏差分别为 0 .4 5%、0 .56%、1.17%。对 4个批号实际样品的测定结果与标准方法的测定结果吻合。Aspirin,phenacetin and caffeine in aspirin compound tablets were determined simultaneously by spectrophotometry and multiplier punitive function method.The average recoveries of these components in synthetic samples are 100.4%,99.78% and 100.6% with relative standard deviations for them are 0.45%,0.56% and 1.17%,respectively(n=10).The results of determination for four batches of actual samples are agreed with those by standard method.This method is simple,rapid,and promising well to be adopted as an official assay method for determination of aspirin compound tablets.
