AB  - An improved quick, easy, cheap, effective, rugged, and safe (QuEChERS) method 
      combined with ultrapressure liquid chromatography tandem mass spectrometric 
      method (UPLC-MS/MS) was developed to simultaneously determine 25 pesticides in 
      Zizania latifolia. The samples were extracted with methanol(MeOH) and 0.1% formic 
      acid (80:20, v/v) and cleaned with C(18) absorbent and primary-secondary amine 
      (PSA). LC separation was performed on a BEH C(18) UPLC column under the condition 
      of gradient elution with the mobile phase consisted of 0.5% formic acid (10 mM 
      ammonium acetate)/MeOH. External standard calibration method with matrix-matched 
      was used for quantification, and good linearity was obtained over a concentration 
      range of 0.5-100 mug/l, with correlation coefficients greater than 0.9901. The 
      limit of detection (LOD) and the limit of quantitation (LOQ) of the 25 pesticides 
      were in the range of 0.2-1.0 microg/kg and 0.5-3.3 microg/kg, respectively. The 
      recoveries ranged from 72% to 118%, and the relative standard deviations (RSDs) 
      were less than 20%. Thus, the proposed method is suitable for the simultaneous 
      determination of 25 pesticides in Z. latifolia.
