摘要两面针为芸香科花椒属植物，在我国主要分布于福建、广东、广西、云南等地，是民间常用的一种植物药，其根、根皮及茎皮入药，主治风湿性关节痛、牙病、胃痛、咽喉肿痛、毒蛇咬伤等症。现代研究证明其具有抗肿瘤、镇痛等作用。但是为了让两面针尽可能发挥其药用价值，需要将其保存完好，什么样的贮存条件才能保障其活性成分最大限度地保留，是本文亟待解决的问题。本文在指出氯化两面针碱、宗多糖以及总黄酮的测定和制备方法基础上，对烘干前后两面针样品重要变化进行了分析，发现烘干后的样品比未烘干的样品重量增加较少，总灰分、总部黄酮、氯化两面针碱、多糖这四种物质在不同的包装情况下含量都会发生变化，密封和真空状态下的变化较不包装要小，同时低温环境下的变化比室温下的变化要小，这是因为密封活着真空包装会隔绝空气中的氧气和水分，希望本文的研究可以为两面针的贮存提供一定的参考指导作用。关键词：两面针；贮存技术；；氯化两面针碱；总黄酮；多糖AbstractBothsidesoftheneedleforRutaceaeZanthoxylum,mainlydistributedinChina'sFujian,Guangdong,Guangxi,Yunnanandotherplaces,isakindofcommonfolkmedicinalplants,root,rootbarkandstembarkusedfortreatingrheumaticjointpain,dentaldisease,stomachpain,sorethroat,snakebitedisease.Modernresearchhasprovedthatithasanti-tumor,analgesicandothereffects.ButinordertomaximizethemedicinalvalueofZanthoxylumnitidum,weneedtopreserveitwell,andwhatstorageconditionscanensurethatitsactivecomponentscanbemaximallypreserved,whichistheurgentproblemtobesolvedinthispaper.Thispaperpointsoutthatinthebasisofpreparationmethodanddeterminationofnitidinechloride,polysaccharidesandtotalflavonoids,onbothsidesoftheneedlesamplesbeforeandafterdryingimportantchangeswereanalyzed,foundthatafterdryingsamplesincreasedbylessthanthesampleweightwithoutdrying,totalash,theheadquartersofnitidinechloride,flavonoids,polysaccharidesofthefourinthepackagingmaterialunderdifferentcontentwillchange,andthechangeofsealingundervacuumpackagingisnotsmall,butchangesinlowtemperatureenvironmentthanthechangeofroomtemperatureshouldbesmall,thisisbecausethesealedvacuumpackagingwillisolatealiveoxygenandmoistureintheair,Ihopethisstudycanbestoredbothsidesoftheneedletoprovidereference.Keywords:twosidedneedles;storagetechnology;;chlorinoflavin;totalflavone;polysaccharide目录毕业设计（论文）.........................................................................................................................................1摘要.............................................................................................................................................................2Abstract...........................................................................................................................................................31前言.............................................................................................................................................................61.1两面针...............................................................................................................................................61.2两面针化学成分...............................................................................................................................61.2.1生物碱成分............................................................................................................................61.2.2其他活性成分..................................................................................................................
