摘要

Abstract > Ternary deep eutectic solvent magnetic molecularly imprinted polymers grafted on silica were developed for the selective recognition and separation of theophylline, theobromine, (+)‐catechin hydrate, and caffeic acid from green tea through dispersive magnetic solid‐phase microextraction. A new ternary deep eutectic solvent was adopted as a functional monomer. The materials obtained were characterized by FTIR spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, NMR spectroscopy, and powder X‐ray diffraction. The practical recovery of the theophylline, theobromine, (+)‐catechin hydrate, and caffeic acid isolated with ternary deep eutectic solvent magnetic molecularly imprinted polymers in green tea were 91.82, 92.13, 89.96, and 90.73%, respectively, and the actual amounts extracted were 5.82, 4.32, 18.36, and 3.69?mg/g, respectively. The new method involving the novel material coupled with dispersive magnetic solid‐phase microextraction showed outstanding recognition, selectivity and excellent magnetism, providing a new perspective for the separation of bioactive compounds. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>摘要</标题> >嫁接在二氧化硅上的三元深共晶溶剂磁性分子印迹聚合物用于选择性识别和分离茶碱，大胆碱，（+） - 儿茶素水合物，以及来自绿茶的咖啡酸通过分散磁性固相微萃取。采用新的三元深共晶溶剂作为功能性单体。所得材料的特征在于通过FTIR光谱，场发射扫描电子显微镜，透射电子显微镜，NMR光谱和粉末X射线衍射。在绿茶中，用三元深共晶溶剂磁性分离的聚合物压印聚合物中茶碱，咔啉，（+） - 儿茶素水合物和咖啡酸的实际回收率为91.82,92.13,89.96和90.73％，分别提取的实际量分别为5.82,4.32,18.36和3.69Ωmg/ g。涉及与分散磁相微萃取的新型材料的新方法显示出突出的识别，选择性和优异的磁性，为生物活性化合物分离提供了一种新的视角。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" > 著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-35800/'>《Journal of separation science. 》</a> <b style="margin: 0 2px;">|</b><span>2018年第17期</span><b style="margin: 0 2px;">|</b> <span>共8页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Li Guizhen&option=202" target="_blank" rel="nofollow">Li Guizhen;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Row Kyung Ho&option=202" target="_blank" rel="nofollow">Row Kyung Ho;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Department of Chemistry and Chemical EngineeringInha UniversityIncheon Korea;</p> <p>Department of Chemistry and Chemical EngineeringInha UniversityIncheon Korea;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li> <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span> <a href="https://www.zhangqiaokeyan.com/clc/159.html" title="化学">化学 ;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=deep eutectic solvents&option=203" rel="nofollow">deep eutectic solvents;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=dispersive magnetic solid‐phase microextraction&option=203" rel="nofollow">dispersive magnetic solid‐phase microextraction;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=functional monomers&option=203" rel="nofollow">functional monomers;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=magnetic molecularly imprinted polymers&option=203" rel="nofollow">magnetic molecularly imprinted polymers;</a> </p> <div class="translation"> 机译：深度共晶溶剂;分散磁性相 - 微萃取;功能性单体;磁性分子印迹聚合物;
