I摘要为了研究枸杞多糖在枸杞中的提取分离更好的方法和提取得率含量最高的方法，本文以单因素试验的基础上，设计正交试验，对枸杞中多糖提取法的工艺条件进行优化并对获得的优化参数进行了放大验证，确定热浸提法最佳工艺提取条件是料液比为1:15，浸提温度为95℃，浸提时间为3小时，得到枸杞多糖的得率为2.56%。该提取工艺条件，是一种提取成本低、枸杞多糖得率较高的方法，结果令人满意。关键词：枸杞多糖，提取分离，含量测定IIAbstractInordertostudytheextractionandseparationofChinesewolfberrypolysaccharidesinlyciumbettermethodandobtainedthehighestrateofcontent,inthispaper,onthebasisofsinglefactorexperiment,orthogonalexperimentdesign,intheChinesewolfberrypolysaccharideextractionprocessconditionswereoptimized,andtoobtaintheoptimizedparametersfortheamplification,ishotextractionoptimumextractionconditionsweredeterminedandsolid-liquidratiois1:15,leachingtemperatureis95,leachingtimeis3hours,theyieldofLBPis2.56℃%,thepolysaccharidecontentofLBPwas43.35%.Itisamethodwithlowextractioncostandhighyieldoflyciumbarbarumpolysaccharide.Keywords：lyciumbarbarumpolysaccharide,Extractionandseparation,ContentdeterminationIII目录摘要......................................................ⅡAbstract..................................................Ⅲ1绪论......................................................11.1研究背景..........................................................11.2枸杞多糖的简介....................................................21.3多糖的提取分离方法................................................21.3.1多糖的提取方法..............................................21.3.2多糖的分离方法..............................................32实验部分..................................................62.1实验材料与仪器....................................................62.1.1实验材料....................................................62.1.2实验试剂....................................................62.1.3实验仪器....................................................62.2热水浸提枸杞多糖......................................
