摘要: 通过超高效液相色谱法,对不同生长特征的五味子样品中5种主要的木脂素成分:五味子醇甲、五味子醇乙、五味子酯甲、五味子甲素和五味子乙素进行测定,同时考察其抗氧化活性。 对所得到的5种木脂素成分的含量及抗氧化数据进行聚类分析和主成分分析,并且通过逐步判别分析建立判别函数,从而筛选五味子优良品种。 主成分分析和聚类结果基本一致,均将样品分为3大类,逐步判别分析的正确率高达90%。

Abstract: 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%.

Key words: Schisandra fruits, ultra performance liquid chromatography, lignans, Pattern recognition
