title: [X-ray diffraction Fourier pattern analysis of natural caculus bovis].
abstract: OBJECTIVE
  To set up a method for analyzing and distinguishing all the chemical components in natural Caoulus Bovis.
  
  
  METHODS
  Powder X-ray diffraction analyses was used to analyze four samples of natural Caculus Bovis, and the X-ray diffraction Fourier pattern was obtained for distinguishing natural Caculus Bovis.
  
  
  CONCLUSIONS
  The method can be used for distinguishing animal medicinal materials.
