title: [Identification study of different Flos Trollii by IR].
abstract: OBJECTIVE
  To establish a method to identify different Flos Trollii with IR spectra and to provide a new technique for their science estimation and quality identification.
  
  
  METHODS
  Their IR spectra were obtained by the method of intuitionistic analysis-selecting point to normalization.
  
  
  RESULTS
  Differences on the shape, the position, the height and the relative intensity of absorption peaks were shown in IR spectra of the ten samples.
  
  
  CONCLUSIONS
  Different Flos Trollii can be identified using IR spectra obtained by the method of intuitionistic analysis-selecting point to normalization. This new method can be used to study the identification features of the influence factors of Traditional Chinese Medicine quality.
