AB  - An ultra performance liquid chromatography-tandem mass spectrometric method 
      (UPLC-MS/MS) has been developed for the simultaneous determination of eight 
      pesticide residues from seed coating in fruits, vegetable and grain. The sample 
      was extracted by methanol-water (1:1, v/v) and determined by ultra performance 
      liquid chromatography-electrospray ionization tandem mass spectrometry in 
      positive mode (ESI+) and multiple reaction monitoring (MRM) mode. The UPLC 
      analyses were performed on an Acquity UPLC C18 column with gradient eluation. The 
      utility of the method was demonstrated by the analysis of crude extracts, with no 
      sample clean up, from soybean. The linear range was 1 - 200 microg/L. The 
      correlation coefficients (r) were under 0.997. The average recoveries of eight 
      pesticides in samples (from 0.006 to 1.2 mg/kg) ranged from 60% to 110%, and the 
      relative standard deviations (RSDs) were less than 10%. The results indicate that 
      the method is easier, faster, more sensitive, and suitable for the qualitative 
      and quantitative confirmation of pesticide residues from seed coating reagent in 
      fruit, vegetable and grain samples.
