Abstract: The study is used by the co-precipitation method to make some uniform particle size and have good Fe3O4 magnetic nanoparticles and their surface modified with oleic acid; oleic acid as the carrier of Fe3O4, quercetin as template molecule, prepared by the microwave assisted molecular imprinted polymer magnetic nanospheres; In raspberry ethyl acetate extract fingerprints for the assessment index, with orthogonal design best preparation; Characterization of equilibrium adsorption constant Kd and maximum adsorption capacity Qmax by Scatchard model.The results show that: This study explores the preparation of MIPs polymerization time by ten times, prepared by the Fe3O4 nanometer level, greatly increase the MIPs of the specific surface area, thereby increase the amount of adsorption (Kd = 0.7322 mg/L, Qmax = 18.92 μmol/g). Successfully extract raspberry flavonoids active ingredients from ethyl acetate which can be used for rapid and large parts of ethyl acetate enrichment raspberry flavonoids.
Template and target information: quercetin, raspberry flavonoids
