Abstract: The basic principle and computing method of the partial least squares method (PLS) applied to a multicompoent analysis were discussed.The optimum experimental condition of simultaneous UV-spectrophotometric determination of the contents of acetaminophen, aspirin and caffeine in acetaminophen compound tablets and the application of PLSin simultaneous multicomponent determination were studied.The average recovery ratio of the three components are 99.88±0.33%, 99.99± 0.14% and 99.92±1.24% (confidence 95%), respectively.No information has ever been available in the literature for the application of PLSto the pharmaceutical analysis.

Key words: Partial least squares method (PLS), Simultaneous determination of multicomponent by spectrophotometry, Acetaminophen compound tablets, Aspirin, Caffeine
