Study on Identification Method of Banqiao Codonopsis Pilosulc with Near-Infrared Spectroscopy

Abstract:

In order to identify the Banqiao codonopsis pilosulc, a geographical indication products,diffuse reflectance spectroscopy of came from four different origins were collected by the Fourier near-infrared spectrometer. The spectroscopy was analyzed with Chemometrics method,and the spectroscopy was pretreated by the second derivative and vector normalized, first derivation and minus a straight line condition. The range of spectra was 7637.3-4165.8 cm-1. The Calibration models of Codonopsis pilosulc were established by the qualification testing, principal component analysis, and cluster analysis respectively, and each model was verified. The results show that the optimal model established by the qualification testing, principal component analysis and cluster analysis can effectively identify authentic Banqiao codonopsis pilosulc , and accuracy rate was 100%. In conclusion, Banqiao codonopsis pilosulc can be identified accurately and quickly by the near-infrared spectroscopy technique.
