AB  - A gallic acid-affinity molecularly imprinted polymer (G-MIP) was first used as an 
      adsorbent for selective identification and capture of luteolin (LTL) in herbal 
      medicine samples. The G-MIP was prepared by using LTL as the template, gallic 
      acid (GA) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as 
      the crosslinking agent, and 2,2'-azobis(2-methylpropionitrie) (AIBN) as the 
      initiator. The properties of G-MIP were characterized by FT-IR, transmission 
      electron microscope, scanning electron microscope, dynamic light scattering, 
      specific surface area, and X-ray photoelectron spectrum. The adsorption 
      conditions were optimized, and the adsorption equilibrium model and adsorption 
      kinetics model of the adsorbent were investigated under the best experimental 
      conditions. The saturated adsorption capacity is 1.24 mg g(-1), which is not only 
      higher than the adsorption capacity of 4-carboxyphenylboronic acid-affinity MIP 
      adsorbent but also superior to those of many reported adsorbents for enriching of 
      LTL. The LTL was quantified by HPLC. The linear range is 0.05-100 mg L(-1), the 
      detection limit is 0.020 mg L(-1). This method was successfully applied in the 
      selective recognition of LTL in herbal medicines with recoveries of 93.9-114.2%, 
      and the relative standards deviations (RSDs) are 0.4-5.6%. Thus, this work 
      provides a potential possibility and practical platform for the determination of 
      LTL in complex matrices.
