Comparision of Bupleurum scorzoneri folium Willd.grouping from different habitats Based on Pattern Recognition with R software

摘要

Bupleurum scorzoneri folium Willd.(BSFW) is a traditional Chinese medicine which is widely distributed in China.To evaluate the quality of BSFW from different habitats,samples from 5 different areas in China were determined by UPLC/MS.The chemical data were dealed with hierarchical clustering,PCA,SPCA,PLSDA and SPLSDA using R software.The results show that these pattern recognition methods can fully reflect the chemical composition of different areas of BSFW,which make it possible to control the quality.
