title: [Identification on Xanthium sibiricum from different habitats by FTIR fingerprint patterns].
abstract: OBJECTIVE
  To establish an FTIR method to identify Xanthium sibiricum from different habitats.
  
  
  METHODS
  FTIR spectra of Xanthium sibiricum from different habitats were analyzed,and the similarity of different fingerprint spectra and the chemical pattern recognition were calculated and analyzed according to the wave numbers of peaks.
  
  
  RESULTS
  Different FTIR spectra of 10 different habitats of Xanthium sibiricum were obtained,and the similarities were all above 0. 96.
  
  
  CONCLUSIONS
  This method can be used for identification on Xanthium sibiricum from different habitats. The results of similarity calculation and chemical pattern recognition further prove the feasibility of this method.
