摘要

Abstract > A novel mixing approach was utilized with a highly sensitive chemiluminescence (CL) method to determine the total phenolic content (TPC) in honey samples using an acidic potassium permanganate–formaldehyde system. The mixing approach was based on exploiting the mixing efficiency of nanodroplets generated in a microfluidic platform. Careful optimization of the instrument setup and various experimental conditions were employed to obtain excellent sensitivity. The mixing efficiency of the droplets was compared with the CL signal intensity obtained using the common serpentine chip design, with both approaches using at a total flow rate of 15?μl?min ?1 ; the results showed that the nanodroplets provided 600% higher CL signal intensity at this low flow rate. Using the optimum conditions, calibration equations, limits of detection (LOD) and limits of quantification (LOQ) for gallic acid (GA), caffeic acid (CA), kaempferol (KAM), quercetin (QRC) and catechin (CAT) were obtained. The LOD ranged from 6.2?ppb for CA to 11.0?ppb for QRC. Finally, the method was applied for the determination of TPC in several local and commercial honey samples. </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> >一种新的混合方法，用于高敏感的化学发光（CL）方法来确定总数酚类含量（TPC）在蜂蜜样品中使用酸性高锰酸钾 - 甲醛系统。混合方法是基于利用在微流体平台中产生的纳米玻璃的混合效率。仔细优化仪器设置和各种实验条件以获得优异的敏感性。将液滴的混合效率与使用常见的蛇形芯片设计获得的CL信号强度进行比较，两种方法以15≤μL的总流速，两种方法结果表明，纳米电池以这种低流速提供600％的CL信号强度。使用最佳条件，校准方程，检测限制（LOD），并获得了无碱，咖啡酸（Ca），kaempferol（kam），槲皮素（QRC）和儿茶素（猫）的量化（LoQ）的限制（LOQ）的限制。 LOD从6.2？PPB用于CA至11.0？PPB用于QRC。最后，将该方法应用于几种局部和商业蜂蜜样品中TPC的测定。 </ 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-26441/'>《Luminescence: The journal of biological and chemical luminescence》</a> <b style="margin: 0 2px;">|</b><span>2018年第5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=Al Lawati Haider A.
