| Abstract: | Four components of Qutongpian were determined by UV spectrophotometry with BP network of Levenberg - Marquardt optimization algorithm. Caffeine and phenobarbitial that are the lower content components in Qutongpian were determined by the combination of the absorbance substraction technique. The mean recoveries and RSD of aminopyrin, phenacetin, caffeine and phenobarbitial were 99.3% , 1.2%; 100.0%, 1.1%; 100.3%, 1.5%; 100.1%, 1.3% respectively. |
