title: [Mass spectrometric analysis of quinazoline alkaloid and limonin from Fructus Evodiae].
abstract: OBJECTIVE
  To study Mass spectrometry of quinazoline alkaloid and limonin from Fructus Evodiae by an electrospray ionization (ESI) tandem mass spectrometry.
  
  
  METHODS
  The ESI source was set at the positive ionization mode, and the MS1 and MS2 spectra of quinazoline alkaloid and limonin were acquired.
  
  
  RESULTS
  The main fragments of quinazoline alkaloid and limonin from Fructus Evodiae were analyzed.
  
  
  CONCLUSIONS
  The profiles of fragments will be usefull to set quality criteria and to study chemical composition of Fructus Evodiae.
