| Abstract: | In order to identify and in-depth excavate the differences of chemical compositions in Premna fulva from different regions,inrared spectra of multi-region sampled individuals were detected using the fourier transform infrared spectroscopy.After that,chemometrics methods including principal component analysis,clustering analysis and principal component loading factors were utilitied to pretreat original spectra data.The results showed that:(1)in 3 dimensional scatter maps,among the different samples,the dist... |
