聚类分析法在黄芩鉴别分类中的应用

Application of Cluster Analysis in Classification of Radix Scutellariae

对10个不同产地的黄芩样品进行了薄层色谱分析,从薄层色谱中提取反映样品间质量差异的数量化特征,全部数据用聚类分析的数学方法进行处理,准确地区分了中国药典规定的正品黄芩和4种非正品黄芩:甘肃黄芩、粘毛黄芩、滇黄芩、丽江黄苓。

Ten samples of Radix Scutellariae from different habitats were analyzed by thin layer chromatography. From the analysis numerical characteristic features were obtained that represent the quality difference of samples. All of the multivariate data were treated with mathematic method of cluster analysis. Scutellaria bai alensis included in Chinese Pharmacopoeia was clearly differentiated from the other four varieties of herbs(S. rehderiana, S. viseidula, S. amoena. S. likiangensis).
