title: [Identification on Chinese materia medica Radix Rehmanniae preparata by X-ray diffraction Fourier pattern method].
abstract: OBJECTIVE
  To develop a new identification and analysis method of Chinese medicinal materia Radix Rehmanniae Preparata.
  
  
  METHODS
  Powder X-ray Diffraction Fourier Pattern.
  
  
  RESULTS
  Experiments and analysis were carried out on five samples. The standard X-ray diffraction Fourier Pattern and characteristic diffraction peaks of Radix Rehmanniae Preparata were obtained.
  
  
  CONCLUSIONS
  This method can be used for identification on Chinese medicinal materia Radix Rehmanniae Preparata.
