英文摘要	The magnetic molecularly imprinted polymers (MMIPs) for resveratrol were prepared by using sur-face molecular imprinting technique with a super paramagnetic core–shell nanoparticle as a supporter. Rhapontigenin, which is the analogues of resveratrol, was selected as dummy template molecules to avoidthe leakage of trace amount of resveratrol. Acrylamide and ethylene glycol dimethacrylate were chosenas functional monomers and cross-linker, respectively. The obtained MMIPs were characterized by usingscanning electron microscopy, Fourier transform infrared spectrum, X-ray diffraction and vibrating sam-ple magnetometer. High performance liquid chromatography was used to analyze the target analytes.The resulting MMIPs exhibited high saturation magnetization of 53.14 emu g⁻¹leading to the fast sep-aration. The adsorption test showed that the MMIPs had high adsorption capacity for resveratrol andcontained homogeneous binding sites. The MMIPs were employed as adsorbent of solid phase extractionfor determination of resveratrol in real wine samples, and the recoveries of spiked samples ranged from79.3% to 90.6% with the limit of detection of 4.42 ng mL⁻¹. The prepared MMIPs could be employed toselectively pre-concentrate and determine resveratrol from wine samples.
