| Abstract: | Aspirin,phenacetin and caffeine in aspirin compound tablets were determined simultaneously by using improved multiwavelength linear regression spectrophotometry.The average recovery of these components in synthetic samples were 100.31%,99.87% and 100.77% and relative standard deviations of 0.35%, 0.25% and 1.37% respectively (n=10).The results of determination for four batches of actual samples agreed with those by standard method.This method is simple and rapid,and promises well to be adopted as an official assay method for determination of aspirin compound tablets |
