AB  - This study was aimed to the establishment of an analytical method for the 
      determination of three exogenous plant hormone residues in bean sprout by high 
      performance liquid chromatography-quadrupole-time of flight mass spectrometry 
      (HPLC-Q-TOF-MS). The target compounds were gibberellins, 6-benzylaminopurine and 
      parachlorophenoxyacetic acid. The QuEChERS (quick, easy, cheap, effective, 
      rugged, and safe) method was used for sample preparation. The analytes were 
      extracted with a solution containing 1% (v/v, if not specified) acetic, 50% 
      ethanol, 49% acetonitrile, and cleaned-up by dispersive solid-phase extraction 
      with diatomite dispersant, then degreased by hexane. The three target compounds 
      were separated on an Eclipse Plus C18 column (100 mm x 3.0 mm, 1.8 microm) with 
      mobile phases A (water containing 0.1% formic acid) and B (methanol) by gradient 
      elution within 15 min, and detected under negative electrospray ionization (ESI) 
      mode. The quantitative analysis was carried out by extracting the peak area with 
      accurate mass. The confirmatory analysis of the target compounds was performed 
      with the qualitative fragments. The results showed that the limits of 
      quantification (LOQs, S/N = 10) for the three target compounds were from 5.0 
      microg/kg to 10 microg/kg. The respective mean recoveries were found to be in the 
      range of 79.1%-96.1%, and the RSDs were 5.7%-10.4%. It was applicable to the 
      analysis of the three exogenous plant hormones in bean sprout samples. This 
      method is simple, fast and efficient.
