艾蒿提取液纯化及在驱虫防蚊功能性纺织品上的应用-纺织工程专业论文xWord文件下载.docx

1、8min。采用浸轧工艺对织物进行驱蚊整理。通过考察整理前后织物接枝增重率、白度变化、电镜分析、红外光谱对织物进行分析，表明艾蒿驱避剂已经整理到织物上。对整理后的织物进行驱蚊效果测试，经过驱蚊整理后的织物具有良好的驱蚊效果，并且水洗十五次后仍具备一定的驱蚊效果。研究证明，艾蒿提取液中含有具备驱蚊效果的各种天然物质，可以作为天然的驱蚊剂。采用艾蒿提取液作为驱蚊剂，分别制备环糊精包合物整理液和艾蒿提取液乳液II整理液，对织物进行驱蚊整理后，织物都具备良好的驱蚊效果，可根据实际需要选取合适的驱蚊整理液制备方法。关键词：艾蒿艾蒿乳液 工艺条件 环糊精整理液 驱蚊织物作者：化丹丹指导老师：蒋耀兴Resea

2、rch on corrosion resistance and thermal shock resistance of Carbon-silicon fiberAbstractArtemisia argyi extract and purification, and its application on anti-mosquito functional textilesArtemisia argyi L, a kind of natural Asteraceae herbs, is widely distributed in China. Due to its plentiful chemic

3、al compositions with physiological activity, it have great potential value in food and drug fields. To prepare Artemisia argyi solution, ethanol extraction method was used, and the solution mainly contained flavonoids, eudesmane, terpineol and trace elements. Current researches have proven that eude

4、smane and terpineol both have amazing aversion activities to mosquitoes. Meanwhile, the fragrant smell also could keep mosquitoes away. whats more, they exbited harmless to human body and environment. This project studied the synthesis of mosquito repellent regulated by Artemisia argyi L, and based

5、on that ,the fabrication of functional textiles which have anti-mosquito effect was also exploited.In the present study, we firstly prepared the Artemisia argyi L solution by using natural pharmaceutical ethanol extraction method. In order to improve its concentration for further applications, the r

6、otary evaporator was used, and the presence of main active compositons we also confirmed by Liquid Chromatograph Mass Spectrometer（LCMS）.Then,using Artemisia argyi L extraction as the raw materials, two different preparation methods were employed to fabricate mosquito repellents.1. cyclodextrin-Arte

7、misia argyi L inclusion complexes was fabricated by using cyclodextrin as the host molecules. FTIR result showed that the strong chemical bonds were formed between them. Meanwhile, scanning electron microscope proved they were stable microparticels.2. Artemisia argyi L emulsion were made by phase-in

8、version method. we also analyzed the technology parameters influencing the size and its distribution of emulsion particles and tested their microstructures by scanning electron microscope. The procedures were just as follows, Artemisia argyi L solution（18%） was blended into emulsifier（3%） and stirre

9、d for 8 min, the HLB values of solutions were then adjusted to 8min.Finally, the functional textiles were made by dip-padding treatment. Compared with the textiles prior to treatment, the functional textiles had binded with mosquito repellents, evidenced by whiteness, mass, FTIR and SEM images. The

10、mosquito test result showed4that it could effectively repel against mosquitoes, and still had some repellent effect after 15 washing.In summory, Artemisia argyi L extraction contained natural compositions with aversion activities to mosquitoes, implying their great potential in fabricating mosquito

11、repellents. we then prepared cyclodextrin -Artemisia argyi L inclusion complexes and Artemisia argyi L emulsion using two simple but effective methods. After the dip-padding treatment, the functional textiles with mosquito repellents exhibited amazing aversion effect, which expanded the application

18、用中药，最早的艾叶药用作用记载于名医别录， 两千多年前孟子就说过：“七年之病，求三年之艾”。长期以来，艾蒿的生物活性得到了开发和广泛应用1。我国端午节民间有挂艾叶、饮艾酒及食用艾饼的习俗。艾草的茎、叶均含有挥发性芳精油，揉揉后就有香气，艾蒿香精喷洒在办公、体息、娱乐、餐厅等场所，具有驱蚊、杀菌、净化空气等作用。我国农村夏季常将干燥的艾叶或茎杆点燃，驱蚊效果不错。夏季人们会受到蚊子侵扰，严重影响人们的睡眠，蚊子对人体皮肤叮咬，让人们感到疼痒难耐，人的身心健康饱受威胁。目前，很多化学合成物质可以达到驱避蚊虫或驱杀蚊虫的作用，但大多为WHO禁用药物。并且由于合成驱避剂长期以来大量使 用，已造成蚊虫抗

19、药性不断提高， 不但驱蚊效果逐年下降，而且会引起神经系统症状以及皮肤损伤，近年来经常见因合成驱避剂的滥用对儿童及孕妇造成各类不良后果的报道，所以越来越多的科技工作者把注意力转移到天然植物基驱避剂上。许多植物本身带有对蚊虫具有驱避作用的气味，并且含有大量具有杀蚊、驱蚊活性的化合物， 利用这些植物制备的精油或提取液作为蚊虫驱避剂，无毒或毒性低，对人类无害，适宜开发各类驱蚊产品。1933 年Campbell 等报道了植物提取物对蚊子幼虫的毒杀效果， 发现植物碱如烟碱、假木贼碱和羽扁豆碱等能够杀死几种库蚊的幼虫3。杨频研究了留兰香油、薄荷油、香茅油、芸香科植物、菊科植物的精油对蚊虫的熏蒸毒杀作用， 结

20、果表明这五种植物精油对蚊虫具有良好的驱杀作用2。ThomasT.G等研究了药薯植物精油对四种蚊虫幼虫的毒杀效果，发现其对三带喙库蚊、埃及伊蚊、斯氏按蚊、致乏库蚊具有优异的驱杀作用。本研究利用天然植物艾蒿作为天然驱避剂，对比分析了几种不同方法制备的艾蒿提取液，结合相关仪器对提取液中主要物质进行了分析，确定其中含有驱避效果的几种有效成分。将制备的艾蒿提取液分别制备成艾蒿乳液和艾蒿环糊精包合物溶液作为驱蚊整理液，利用浸渍法、浸轧法对织物进行驱蚊整理。对经过整理的织物进行驱蚊效果测试，证明了驱蚊整理后的之后具有良好的驱蚊效果。1.2 艾蒿概况1.2.1 艾蒿的国内外开发利用现状艾蒿在我国已有五千多年的

21、历史，历代文献中有关艾蒿的药用或食用记载很多，这说明前人对艾蒿的开发利用颇为广泛4。现在国内市场上已开发出艾叶系列保健食品。艾叶保健茶是以艾嫩叶为原料，加工制成的茶叶，富含其艾叶中药成分， 具有良好的保健作用，是很好的保健茶5。我国河南省南阳国草科技开发公司以艾叶为主要原料，科学配以多种名贵中草药，运用高科技手段和现代工艺研制成了一种不含尼古丁的保健型绿色特殊香烟替代品，以达到对呼吸系统的保健作用，通过吸烟的方式，对吸食者的呼吸系统进行艾条熏灸，可强化免疫功能4。艾蒿精油香气浓郁透发，对人体无毒副作用，国内已有厂家生产出以艾为主，配以其他驱蚊药制成的蚊香，用于驱蚊及空气消毒，防治传染病流行效果很好。目前国外市场对艾蒿的开发利用比较而言，韩国和日本对于艾蒿的开发研究利用较多
