title: [Content comparison of main chemical compositions in Gardenia jasminoids roasted with ginger juice].
abstract: OBJECTIVE
  To compare the contents of the main chemical compositions in Gardenia jasminoids before and after being roasted with ginger juice.
  
  
  METHODS
  Four diterpenoid pigments constituents (C-1, C-2, C-3, crocetin) were determined simultaneously by UPLC on an Agilent Poroshell 120 EC-C18 column at 35 degrees C with the methanol-0.5% formic acid anhydrous in gradient elution as the mobile phrase. The detection wavelength was set at 440 nm and the flow rate was 0.4 mL x min(-1). Two iridoids constituents (G-1, G-2) were determined simultaneously by HPLC on an Agilent TC-C18(2) column at 35 degrees C with acetonitrile-0.5% formic acid anhydrous (18:82) as the mobile phrase. The detection wavelength was set at 238 nm and the flow rate was 1.0 mL x min(-1).
  
  
  RESULTS
  After being processed with ginger juice, the contents of the diterpenoid pigments constituents decreased slightly and the contents of the iridoids constituents increased slightly.
  
  
  CONCLUSIONS
  The contents of the main chemical compositions in G. jasminoids roasted with ginger juice increased slightly with some regularity, but there were no significant differences.
