Single factor experiments were implemented to investigate the effects of ethanol concentration, solidliquid ratio, ultrasonic working time, ultrasonic power, respectively, on the extraction rate of total Flavonoids from Caulis clematidis Aemandi. Othogonal test was used to optimize the results showed that: At room temperature,the optimal experiment conditions was the concentration of ethanol is 90%,the solidliquid ratio is 1:30 (g/mL),ultrasonic working time 8 min, ultrasonic power 200 W. The experiment was repeated three times under the optimal conditions ,average extraction rate was %.Comparing with traditional methods, this method significantly shortens the working time of ultrasonic, and improving the extraction study provides the experiment basis for mercial process. Keywoods： Ultrasonic。與傳統(tǒng)方法相比，該方法明顯縮短了提取時(shí)間，提高了黃酮的提取率。結(jié)果表明在室溫條件下，最優(yōu)工藝條件為： 乙醇濃度 90%，料液比 1:30 g/mL，超聲波工作時(shí)間 8 min，超聲波功率 200 W。本聲明的法律結(jié)果由本人獨(dú)自承擔(dān)。除文中已經(jīng)注明引用的內(nèi)容外，論文中不包含其他個(gè)人已經(jīng)發(fā)表或撰寫過的研究成果，也不包含為獲得湖北民族學(xué)院或其它教育機(jī)構(gòu)的學(xué)位或證書而使用過的材料。 學(xué)號(hào)： 071140208 湖北民族學(xué)院本科畢業(yè)論文 超聲輔助提取川木通總黃酮的工藝研究 院 系： 生物科學(xué)與技術(shù)學(xué)院 姓 名： 周 茜 專 業(yè)： 生物工程 指導(dǎo)教師： 劉曉鵬 中國(guó)恩施 二〇一五年五月 : 071140121 BACHELOR’S THESIS OF HUBEI UNITroloxRSITY FOR NATIONALITIES Ultrasonic assisted extraction of total Flavonoids from Caulis clematidis armandi Major: Biological engineering StuName: Qian Zhou Mentor: Xiaopeng Liu Eenshi china May 6th, 2020 鄭重聲明 本人鄭重聲明所呈交的學(xué)位論文《 超聲輔助提取川木通總黃 酮的工藝研究 》是我在導(dǎo)師 劉曉鵬 的指導(dǎo)下獨(dú)立進(jìn)行研究工作所取得的研究成果。對(duì)本文的研究做出重要貢獻(xiàn)的個(gè)人和集體，均已在文中以明確的方式進(jìn)行了說明。 作者簽名： 年 月 日 I
