过去几十年来，多变量数据分析的应用已成为一种流行的方法，主要是因为它可以提供其他方式无法获得的信息。信息包括分类、查找相似性、查找关系、查找主成分的物理意义等。收集了53味中药材11种香豆素类物质，采用高效液相色谱法进行测定。通过主成分分析（PCA）和聚类分析对结果进行研究。结果表明，样品可以合理聚类，符合我国不同地区蛇床子果实香豆素含量规律和分布的差异。 (C) 2001 Elsevier Science B.V. 保留所有权利。
Application of multivariate data analysis has become a popular method in the last decades, mainly because it can provide information not otherwise accessible. The information includes classification, searching similarities, finding relationships, finding physical significance to principal components, etc. Fifty three Chinese medicinal herbs of eleven kinds of coumarins were collected and determined by HPLC. The results were studied by principal component analysis (PCA) and cluster analysis. It was showed that the samples could be clustered reasonably into different groups, which correspond with variation of regularity and distribution of coumarin of Cnidium monnieri fruits in different regions of China.
