Identification of Panax japonicus var.major from Different Origins Using UV Spectra Fingerprint Combined with Partial Least Squares Discriminant Analysis
摘要
Abstract
To establish a rapid method for the identification of Panax japonicus var.major( Araliaceae) from different geographical origins and provide the basis for quality evaluation,UV spectra combined with partial least squares discriminant analysis( PLS-DA) method was used to distinguish P.japonicus var. major samples from different cultivation regions.Then the difference of P.japonicus var.major in UV spectra was analyzed, and the absorbance was investigated by PLS-DA.The results indicated that the ab-sorption wavelength of the UV fingerprint of P.japonicus var.major samples from different regions was similar, and the peak intensity was different, which could effectively distinguish the P.japonicus var. major samples from different geographical origins.The PLS-DA method successfully separated the samples from Nujiang,Yuxi,Dali and Wenshan.Moreover,samples collected from Dali and Wenshan were similar, while the remaining samples were far from each other.关键词
