Abstract: In order to prepare a novel adsorption material selective to hesperidin(HES), a HES imprinted polymer(MIP) was prepared in methanol with HES as template molecule,acryl amide(AM) as functional monomer,ethylene glycol dimethacrylate(EDMA) as cross-linker.Its adsorption property and selectivity were evaluated by equilibrium adsorption experiment method.The mechanism in imprinting system and recognition progress were explored.The obtained results revealed appriapriate affinity and selectivity of HES-MIP to HES.In 0.04 mol / L HES methanol solution,the distribution coefficients KD of HES on MIP and corresponding NMIP are 10.17 and 2.973,respectively.The imprinting factor α is 3.421.Comprard to the analogues of Rutin and narigin,the corresponding selectivity factor β reached 2.446 and 1.446.The MIP was furthermore used in complex sample and analyzed by high efficiency liquid phase chromatography.The results were pleased which indicated a possibility of being separation and enrichment material.
