title: [Analysis on chemical constituents of Gardenia jasminoides by UHPLC-Q-TOFMS].
abstract: OBJECTIVE
  To analyze the chemical constituents of Gardenia jasminoides by UHPLC-Q-TOFMS.
  
  
  METHODS
  A ACQUITY UPLC HSS T3 (100 mm x 2.1 mm, 1.8 microm) column was used. The mobile phase consisted of water containing 0.1% methane acid and acetonitrile was used in gradient elution. The flow rate was 0.4 mL/min. TOFMS was applied for qualitative analysis under negative ion mode.
  
  
  RESULTS
  Under optimized condition, 18 major constituents in Gardenia jasminoides were identified by quadrupole-time of flight mass spectrometry and structure-relevant fragment ions.
  
  
  CONCLUSIONS
  A simple and reliable method using UHPLC-Q-TOFMS is established and can be used to identify the chemical constituents of Gardenia jasminoides.
