    Abstract Three ingredients in simulated Zengxiao Lianhuang Tablets were determined simultaneously by means of artificial neural network based on error back-propagation(BP).The mean recoveries and the relative standard deviation of sulfadiazine,sulfamethoxazole and trimethoprim were 101.0%,0.66%;99.4%,1.1%;100.4%,1.2% respectively.The effect of the network structure and network parameter on the analytical result was discussed. ......
