title: [Rapid Identification of Fresh-cut and Sulphur Fumigation Processed Fritillaria thunbergii Bulb Slices Based on Near-infrared Spectroscopy].
abstract: OBJECTIVE
  A rapid identification model of the fresh-cut and sulphur fumigation processed Fritillaria thunbergii bulb slices was developed by near-infrared spectroscopy (NIR) with chemometrics method.
  
  
  METHODS
  186 batches of Fritillaria thunbergii bulb slices were collected from the two main producing areas Ningbo and Pan'an in Zhejiang Province, and the near-infrared spectrums were gathered to establish the qualitative identification model by discriminant analysis.
  
  
  RESULTS
  The identification model was developed by choosing the spectrum of 9,881.46-4,119.20 cm(-1) and "MSC + spectrum + Ns" to the original spectral preprocessing, and then was verified by prediction set, with 100% identify accuracy.
  
  
  CONCLUSIONS
  The rapid identification model of the fresh-cut and sulphur fumigation processed Fritillaria thunbergii bulb slices by NIR is feasible and efficient.
