AB  - A method for the determination of 55 fungicides in siraitia grosvenoriis by 
      QuEChERS and high performance liquid chromatography-tandem mass spectrometry 
      (HPLC-MS/MS) was established. The samples were extracted with acetonitrile 
      containing 1%(v/v) acetic acid, then dehydrated by anhydrous magnesium sulfate 
      and purified by anhydrous sodium sulfate, N-propyl ethylenediamine (PSA) and C18. 
      Then, 95% (v/v) acetonitrile aqueous solution (organic phase) and water (aqueous 
      phase), both containing 0.005 mol/L ammonium formate and 0.01% (v/v) formic acid, 
      were used as mobile phases with gradient elution. The compounds were tested by 
      positive electrospray ion source (ESI(+)) and dynamic multiple reaction 
      monitoring (DMRM) mode. Fifty-five fungicides were quantified by external 
      standard method considering matrix effects. The correlation coefficients (R(2)) 
      were greater than 0.99, which indicated that the linear dependence of the 55 
      fungicides were good in the range of 1.0-100.0 mug/kg. The LODs (S/N>3) and LOQs 
      (S/N>10) of all the fungicides were 1.0 mug/kg and 10.0 mug/kg, respectively. The 
      recoveries were in the range of 76.96%-118.45% and the relative standard 
      deviations (RSDs) ranged from 3.44% to 19.63% (n=6). This method has the 
      advantages of rapidity, accuracy and sensitivity for the high-throughput 
      detection of fungicides residues in siraitia grosvenoriis.
