AB  - The determination of trace plant growth regulators (PGRs) residues in water and 
      food samples make it crucial to develop novel sample pretreatment methods for the 
      enrichment of PGRs. Herein, a novel magnetic hyper cross-linked polymer 
      (M-CTT-9OH-HCP) was constructed and served as a magnetic adsorbent for the 
      efficient extraction of some PGRs from water, watermelon, tomatoes, and milk 
      samples for the first time. Combined with high performance liquid 
      chromatography-fluorescence detection (HPLC-FLD), the established method 
      presented a good linearity (0.03-60.0 ng g(-1) (ng mL(-1)), (r) >/= 0.9973), 
      satisfactory accuracy with method recoveries (83.0%-119%) and acceptable 
      precision with the intra-day and inter-day variations (expressed as the relative 
      standard deviations (RSDs) </= 9.8%). The limits of detection (LODs) and limits of 
      quantitation (LOQs) were in the range of 0.01-1.50 and 0.03-5.00 ng g(-1)/ ng 
      mL(-1). The results show that the established method is sensitive and efficient 
      for the determination of PGRs in real samples.
