| 摘 要： | 聚类分析又称集群分析,它是研究“物与类聚”的一种数理统计方法,聚类分析可将一些观察对象依据某些特征加以归类。已经在生物学和医学分类问题1]以及中药的鉴别与质量评价2]中获得广泛应用。祁俊生等3]利用因子分析和聚类分析探讨了微量元素含量与中药药性的相关性。梁逸曾

| Abstract: | The contents of As,Cd,Hg and Pb in 27 Chinese medicinal herbs were determined by ICP-MS with microwave assisted digestion.Cluster analysis was applied to study the distribution characteristics of As,Cd,Hg and Pb in different kinds of Chinese medical herbs from different sources.The result of cluster analysis showed that the contents of As,Cd,Hg and Pb from different sources were significantly different.It is helpful in the quality control and source identification of Chinese medicinal herbs. |
