Abstract: OBJECTIVE Without any separation, simultaneous determination of four main components in the compound children's phenobarbital tablet. METHODS Based on convolution spectrometry with the excellent cacu-lation method-PLS method used convolution spectrometry of computer information process technology. RESULTS Components of compound children's phenobarbital tablet are aspirin, phenacetin, caffine and phenobarbital. Their average recoveries and RSD were 99.75,0.92%;100.47,0.56%;99.82,1.12%;100.08,0.86%. CONCLUSION The method is used for qualitative control of compound children's phenobarbital tablet.
