title: [The application of infrared spectra and clustering analysis in the discrimination of geographical origin of Flos Chrysanthemi].
abstract: OBJECTIVE
  To identify the origin of Flos Chrysanthemi.
  
  
  METHODS
  FTIR (Fourier transform infrared spectroscopy) and SIMCA (sofe independent modeling of class analogy).
  
  
  RESULTS
  The correctness of every classification was higher than 60%.
  
  
  CONCLUSIONS
  This approach was proved to be a reliable and practicable method for the discrimination of geographical origin of Chrysanthemum.
