AB  - Herein, an electrospun composite from poly(vinyl alcohol) (PVA) and Stevia 
      extract as a cross-linked nanofibrous was prepared with incorporating Fe-metal 
      organic framework@Au nanoparticles (MIL-88A@AuNPs). The final composite was 
      characterized, and then used as an efficient sorbent in pipette-tip micro 
      solid-phase extraction (PT-microSPE) of eight selected pesticides in food samples 
      followed by HPLC-UV analysis. Under the opted conditions, the linearity was in 
      the range of 1.0-1000.0 ng mL(-1) for atrazine and ametryn, 3.0-1500.0 ng mL(-1) 
      for tribenuron-methyl, metribuzin, profenofos and chlorpyrifos, 5.0 to 
      1500.0 ng mL(-1) for phosalone, and 5.0-2000.0 ng mL(-1) for malation with 
      coefficient of determination (r(2)) >/= 0.9943. The LODs (based on S/N = 3) ranged 
      from 0.3 to 1.5 ng m L(-1). The relative standard deviations (RSDs) were between 
      5.2% and 6.6% (intra-day, n = 5) and 5.9%-7.4% (inter-day, n = 3) for three 
      consecutive days. Ultimately, the capability of the method in various food 
      samples was appraised with good recoveries (79.3 to 97.6%).
