Abstract: Employing resveratrol as template molecule, acrylamide as functional monomer and ethyleneglycol dimethacrylate as cross-linkers, a core-shell resveratrol imprinted microspheres was prepared based on the surface of SiO2 with a surface imprinting technique. The molecularly imprinted microsphere was characterized by infrared spectroscopy and scanning electron microscopy, and the results showed that the surface grafting of molecularly imprinted polymer-shell particle on SiO2 was successful and the particles were evenly distributed. High performance liquid chromatography was also used to investigate the imprinted microsphere adsorption performance, and the results showed that the imprinted microsphere exhibited good recognition performance. The maximum adsorption capacities were Q(max1) = 9.087 mg/g and Q(max2) = 13.80 mg/g by the model of Scatchard analysis. The imprinted micospheres was applied to separate resveratrol from the extraction of rhizoma polygoni cuspidate successfully
