柚皮素

The recognition capability and adsorption rate of MIP can be significantly enhanced by selective modification.Separation factor could be increased from 1.60 to 3.06 after modification when naringenin was chosen as competitive molecules, and the time needed for adsorption equilibrium could be reduced from 100 min to 60 min.Within a certain range, increasing template molecule concentration or diazomethane dosage, or adopting solvent which had weaker hydrogen bond action with template molecules could all improve the modification effect.

结果表明，选择性修饰能明显提高MIP的识别能力与吸附速度，以柚皮素为竞争分子，分离因子可从修饰前的1.60提高到修饰后的3.06，吸附平衡时间从修饰前的100 min降低至修饰后的60 min；在一定范围内提高模板分子浓度，增大重氮甲烷用量，采用形成氢键能力较弱的溶剂，均能提高修饰效果。
