title: [Identification of Aaron's beard with clustering analysis by attenuation reflection-Fourier transform infrared spectrometry].
abstract: OBJECTIVE
  To establish a new method to discriminate Aaron's beard by Fourier transformation infrared spectrometry.
  
  
  METHODS
  Attenuation Reflection-Fourier transformation infrared spectrometry with clustering analysis was used to the identification of Aaron's beard.
  
  
  RESULTS
  There were obvious differences in Aaron's beard. The results are consistent with that of morphologic study.
  
  
  CONCLUSIONS
  This method is rapid, simple and economical, and can be used to the quality control.
