title: [The powder X-ray diffraction analysis with Fourier spectrum of Chinese material medica Cortex Cinnamomi].
abstract: OBJECTIVE
  To develop a method for the identification of Chinese medicinal materials in diffraction space.
  
  
  METHODS
  Using powder X-ray diffraction analysis to obtain the Fourier spectrum of 10 samples of Cortex Cinnamomi.
  
  
  RESULTS
  The analysis shows that each of the 10 samples has its own Fourier pattern topology and characteristic peaks which are connected with its chemical composition.
  
  
  CONCLUSIONS
  Cortex Cinnamomi can be identified successfully according to its topology and characteristic peaks.
