title: [A new identification and quautitation method for radix Salviae miltiorrhizae].
abstract: OBJECTIVE
  To develop an identitication and quantitation method for Radix Salviae Miltiorrhizae.
  
  
  METHODS
  The powder X-ray Diffraction Fourier Fingerprint Pattern technique was used for this purpose. The high performance liquid chromatography method was used to evaluate the quantity of Tanshinone II A in 9 samples and 1 drug reference substance. The relationship of diffraction peak intensity and content of Tanshinone II A was investigated.
  
  
  CONCLUSIONS
  The powder X-ray diffraction Fourier Fingerprint Pattern analysis technique can be used to identify Radix Salviae Miltiorrhizae and to evaluate the quantity of Tanshinone II A in the drug at the same time.
