Classification of Astragalus Membranaceus (Fisch.) Bge.Var.Mongholicus(Bge.)Hsiao from Different Areas Based on Chemometric Methods with R Software

摘要

Astragalus membranaceus (Fisch.) Bge.var.mongholicus(Bge.)Hsiao(AMB) is a common Chinese herbal medicine which is widely distributed in China. To evaluate the quality of AMB from different habitats, samples from 7 different areas in China were determined by UPLC/MS. The chemical data were dealed with several chemometric methods such as hierarchical clustering, PCA, SPCA and PLSDA using R software. The results show that these chemometric methods can fully reflect the chemical composition of different areas of AMB, especially PLS has efficient discrimination ability of classification, which makes it possible to control the quality.
