title: [Content comparison of diterpenoid pigments in different processed products of Gardenia jasminoides].
abstract: OBJECTIVE
  To compare the contents of diterpenoid pigments in the different processed products of Gardenia jasminoides.
  
  
  METHODS
  The separation of Crocin 1, Crocin 2, Crocin 3, Crocetin were determined simultaneously by HPLC on a kromasil C18 column at 35 degrees C with the m methanol-acetonitrile-0.3% formic acid anhydrous in gradient elution as the mobile phrase. The detection wavelength was set at 440 nm and the flow rate was 1.0 mL x min(-1).
  
  
  RESULTS
  The obtained linearity of the four components was better over 0.9995 and the average recoveries were 97.77%, 100.05% , 98.40%, 101.02%, respectively.
  
  
  CONCLUSIONS
  The method is simple, accurate with good reproducibility. The results showed that the remarkable variation regulations appear among the different processed products.
