AB  - A method by using a modified QuEChERS (quick, easy, cheap, effective, rugged and 
      safe) and gas chromatography-triple quadrupole tandem mass spectrometry 
      (GC-MS/MS) was established to analyze 88 pesticide residues in cranberry plant 
      extract. The sample was extracted with acetone-hexane (1: 1, v/v) containing 1% 
      acetic acid, then cleaned-up by ethylenediamine-N-propyl silyl (PSA) and graphite 
      carbon (GCB). The extract was determined by GC-MS/MS in multi-reaction monitoring 
      (MRM) mode, and external standard method was applied to quantified the 
      pesticides. All the 88 pesticides showed good linearity in the range of 0. 001 - 
      0. 2 mg/L, and the limits of quantification (LOQs, S/N > or = 10) were all less 
      than 31. 5 microg/kg. The average recoveries of all the pesticides were in the 
      range of 71. 4% to 116. 6% at three spiked levels of 5, 25 and 50 microg/kg in 
      cranberry plant extract, with the relative standard deviations (RSDs) of 2. 4% - 
      16. 9%. The results demonstrated that this method is simple, rapid and suitable 
      for the determination of 88 pesticide residues in cranberry plant extract. The 
      analytical sensitivity and accuracy can meet the requirements of multiple 
      pesticide residue analysis.
