Ultra performance liquid chromatography(UPLC) was used to determine the content of lignans of Schisandra fruits with different growth characteristics. The antioxidant activity of these samples was also studied. In order to screen the superior kinds of these samples,principal component analysis,cluster analysis and stepwise discrimination analysis were used to analyze the above data. Principal component analysis and cluster analysis results divided the origin samples into three categories. The correct rate for screening the superior kinds of Schisandra fruits via stepwise discrimination analysis is 90%.
