主 题：Tradition Chinese Medicine Micro NIR 170 spectrometer Radir codonopsis
摘 要：At present,Tradition Chinese Medicine(TCM)industry in China is in the stage from the empirical development to industrial *** infrared(NIR)spectroscopy has been widely used in the quality control of TCM s modernization with its characteristics incuding rapidness,nondestruction,simplicity,economy,and so *** this study,as one type of a portable micro NIR spectrometer,Micro NIR 1700 was used to establish the qualitative models for identification of geographical region and authenticity of Radix codonopsis based on discriminant analysis(DA)*** of the DA models had better predictive ability with 100%*** addition,a method for rapid quantitative analysis of polysaccharide in Radix codonopsis was also developed based on Micro NIR 1700 spectrometer with partial last-squares(PLS)*** the PLS calibration model,the *** of samples were pretreated with different preprocessing methods and the spectral region was selected with different variable selection methods as *** performance of the final PLS model was evaluated according to correlation cofficient of calibration(Rc),correlation coefficient of prediction(Rp),root mean squared error of cross validation(RMSECV),and root mean squared of prediction(RMSEP).The values of Re,Rp,RMSECV,and RMSEP were 0.9775,0.9602,2.496,and 2.734 g/mL,*** work demonstrated that micro infrared spectrometer could be more convenient and rapid for quality control of Radix codonopsis,and the presented models would be a u1seful reference for quality control of other simi lar raw materials of TCM.
