| Abstract: | Near infrared spectroscopy(NIRS) was used in the identification and rapid classification of donglingcao tablets from different manufacturers.NIRS technology was employed to collect near infrared spectra of donglingcao tablets.Different chemometrics methods and clustering analysis for principal components were used to discriminate donglingcao tablets.The correct classification rate was 100%,and it could be concluded that the composition and production process of donglingcao tablets were different.The results... |
