AB  - A novel method was established for the determination of six plant growth 
      regulators (PGRs), 2,4-dichlorophenoxy acetic (2,4-D), 4-chlorophenoxy-acetic 
      acid (CAP), 4-(3-indolyl)-butyric acid (BAA), forchlorfenuron (CPPU), abscisic 
      acid (ABA) and trans-zeatin (ZT) in strawberry using liquid 
      chromatography-quadrupole-time of flight mass spectrometry (LC-Q TOF MS). The 
      Quick, Easy, Cheap, Effective, Rugged and Safe method (QuEChERS) has been 
      validated for the extraction. In this QuEChERS method, the sample was extracted 
      by acetonitrile and cleaned up with C18 adsorbent. The extract was measured 
      directly by LC-Q TOF MS with electrospray ionization in negative mode. The 
      compounds were separated on an Eclipse XDB-C8 column (150 mm x 4.6 mm, 5 microm) 
      with acetonitrile-5 mmol/L ammonium acetate-0. 1% formic acid as mobile phase 
      under gradient elution. The confirmatory analysis was carried out by determining 
      the accurate masses of all compounds and fragment ions upon Target MS/MS. The 
      limits of detection (LODs) were between 1 microg/kg and 5 microg/kg. The linear 
      range was 0.005-1.0 mg/L for each analyte. The recoveries ranged from 87% to 107% 
      with the relative standard deviations (RSDs) less than 10% (n = 6). The method 
      was proved to be simple and accurate.
