| 中文摘要: |
| 以接枝双键的凹凸棒土(TM)为载体,槲皮素为模板分子,采用表面印迹技术制备对槲皮素具有特异吸附性能的分子印迹聚合物(MIP)。利用光谱法选择实验条件及对化合物表征。采用静态法研究聚合物对槲皮素的结合性能与识别性能。结果表明,该分子印迹材料对槲皮素具有特异的识别特性,优良的亲和性,提高了传统聚合物的结合率。以该印迹聚合物为固相萃取材料,结合高效液相色谱法,对白菜中的槲皮素进行分离富集,方法回收率为84.0%-90.6%,相对标准偏差低于5.6%。 |
| 英文摘要: |
| A new type of molecularly imprinted polymer(MIP) with high selectivity to quercetin had been synthesized by surface molecular imprinting technology, using quercetin as template molecule and modified attapulgite as carrier．The optimum functional monomer , the structure of MIP ,the binding properties and recognition ability of MIP for quercetin were selected and characterized by spectroscopy and static method respectively. The results demonstrated that MIP had specific recognition selectivity and excellent binding affinity for quercetin ,morewhile improved binding rate of traditional MIPs. The MIP as solid phase extraction (SPE) materials coupled with HPLC was using for separation and enrichment of quercetin in cabbage .The recoveries of the development method was in range from 84.0% to 90.6%,and the RSD was less than 5.6%. |
