Principal Component Analysis and Cluster Analysis of Trace Elements in Radix Scutellariae on Chinese traditional medicine

ZHANG Yifan(Department of Pharmacy,Shanghai Institute of Health Science,Shanghai 201318,China)  
Objective: To study the contents and distribution of trace elements of Radix Scutellariae on Chinese Traditional Medicine gathered from different habitats of Shandong provinces.Methods: Trace elements of Radix Scutellariae of chinese herbal medicin have been cluster analyzed by using the principal component analysis method and the statistic software SPSS.Results: 3 principal components are obtained,and the contributing rate of every one among the 3 main constituent is over 91.785%.Based on these principal components,Germplasms are clustered into 3 group based on these principal components and the sum of squares level.Conclusion: The results provide scientific basis for research and identification of Radix Scutellariae.
