PG  - 27-32
AB  - A high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/ MS) 
      method was established for the determination of inabenfide in fruits, vegetables, 
      tea, honey, cereals and animal-derived foods. The food samples were extracted 
      with acetonitrile, then purified by dispersion solid phase extraction using 
      primary secondary amine (PSA) and C18 as solid phase. The residue was determined 
      and confirmed by HPLC-MS/MS and quantified by external standard method. The mass 
      spectrometric detection was operated with electrospray in positive ionization 
      mode and inabenfide was identified in multiple reaction monitoring (MRM) mode. 
      The interference of matrix was reduced by the matrix-matched calibration standard 
      curves. The linear range of the method was 1 - 100 microg/kg, with the 
      correlation coefficients (r2) of 0.998 - 0.999. The recoveries of inabenfide 
      spiked in food samples were 85.2% - 112.4% at the spiked levels of 5, 10, 50 
      microg/kg. The relative standard deviations (RSDs) were less than 8.5%. The 
      limits of detection (LODs) were 0.08 - 1.64 microg/kg, and the limits of 
      quantification (LOQs) were 0.30 - 5.48 microg/kg. The results showed that the 
      proposed method is sensitive and accurate for the determination of inabenfide in 
      foodstuffs.
