Magnolia officlnalis e from dry skin, bark and branch skin of Magnolia officinalis Wils and Magnolia officinalis Rehd. Et wils. var. biloba Rehd. et Wils. Magnolol and honokiol are the main active ingredients, and they have a wide range of pharmacological effects. such as Antiinflammatory, antiarrhythmic, antiepileptic, antiplatelet, antibacterial inhibition and the role of muscle contraction, further more they can inhibit the oxidation products of nitrogen and the expression activity of tumor necrosis factor α. Extract the active ingredients of Chinese medicine in the traditional methods mainly are acid alkaline extraction method, water extraction, ethanol extraction, separation of polyamide extraction, alkaline extraction resin technology, and supercritical CO2 extraction, and Ethanol extraction method in which as a result of cheap, small pollution, and other characteristics suitable for industrial production have been widely used. In this paper, orthogonal experimental design as a tool and extract yield as a quality indicator, we obverse the extraction process of Magnolol and Honokio by extracting in alcohol, focusing on the concentration of ethanol, refluxing time, the number of extraction, solvent usage and other factors on the yield of extract, by their better extraction conditions for extracting time 120min, the concentration of 70% ethanol, 6 times the amount of solvent, extracting the number of 3 times the yield of extract up to %. And with range analysis, variance analysis of experimental data analysis, the relationship between the primary and secondary factors is that the ethanol concentration extract the number of solvent usage extraction time.. Ethanol concentration on the extract yield has the greatest impact, and the yield of extract is highest when Ethanol concentration is 70%. Followed by the extraction of the number, the greater the number of extraction, the higher yield of extract.. Followed by the amount of solvent, approving 6 times the amount of solvent is the best. The impact o f the smallest factor is the extraction time, with the extraction time, higher yield of extract, but after the extraction time 120min, and then to extend the extraction time, but lower yield of extract. So it can be considered to shorten the extraction time, thus reducing energy consumption, enhance economic efficiency. In this paper, the research not only provide a theoretical basis for industrial extraction of the active ingredient Honokiol the design process, but also for indepth study of the pharmacological activity Honokiol provide material basis for the active ingredients of herbs Honokiol extraction and further indepth study guide has a certain significance. key words: Honokiol, extraction process , orthogonal experiment method , ethanol extraction. xxxx 大學(xué)本科 畢業(yè)論文 第 V 頁 目 錄 第 1 章 緒論 …… …………………………………………………………………..………1 厚樸的研究概況 …………………………………………...……..… ..…… ...………1 形態(tài)及習(xí)性 …………………………………..……………..……… ...………...…1 性狀鑒 別 及顯微鑒別 ……………………………… ..….. ………… ...…………...2 主要成分 ……………………………….……………………..…………………... 3 藥理作用 …………………………….………………………..…………………...7 臨床研究 ……………………………….……………………..…………………...9 厚樸中厚樸醇與和厚樸酚提取方法 概況 …………..……………..…………….…1 0 堿提酸沉法 …………………………….……………………....……………...…1 1 溶劑提取法 ……… ………………………...……………………...……………..11 聚酰胺分離提取法 ……………………….………………..…………………….1 3 堿提樹脂工藝 …………………………….……..…………………..…………...1 3 超臨界 CO2 萃取 …………………………………...……………………………1 3 本論文研究目的、內(nèi)容及其意義 ……………………………………..……...……13 研究目的 ……………………..……………..……………………………………13 研究?jī)?nèi)容 ………………..………………………………………………..………1 3 研究意義 ………………………..………………………..……………..…..……14 第 2章 厚樸中的厚樸酚 與和厚樸酚提取工藝研究 ………………………...…..…....…15 實(shí)驗(yàn) 原理 …………………..……………………………………………...…………15 實(shí)驗(yàn)儀器、材料與試劑 …………………………………………………...…………15 實(shí)驗(yàn)材料 ………………..…………………………………. ……….……………15 主要試劑 ………………………..….…………………………….………………15 儀器設(shè)備 ……………………..…………………………………..………………15 實(shí)驗(yàn)內(nèi)容 ………………………..…………………………………………………...16 實(shí)驗(yàn)步驟 ………………………..…….………………………………………….16 鑒定 ……………………………..…….………………………………………….17 結(jié)果與討論 ………….……………..……. ………………………………………….1 8 xxxx 大學(xué)本科 畢業(yè)論文 第 VI 頁 實(shí)驗(yàn) 結(jié)果 …………………..………….………………………………………….1 8 結(jié)果 分析 …………………..………….………………………………………….1 8 討論 ………………………..………….………………………………………….2 2 提取過程中出現(xiàn)的問題 …..………….………………………………………….2 3 應(yīng)用前景 ………………..………….…………………………………………….23 結(jié)論 …………………………………… …………………………………………………..2 5 致謝 …………………………………………………………..………………………………………...
