中文摘要: 为确定豆腐柴多酚的最佳提取工艺条件，在单因素试验基础上，采用三因素三水平的响应面试验优化设计方法，研究乙醇体积分数、超声温度、提取时间对多酚提取率的影响，得到最佳提取工艺条件为液料比40 mL/g、乙醇体积分数52%、超声温度74℃、提取时间33min，在此条件下豆腐柴多酚提取率为（42.43±1.38）mg/g。
Abstract:In order to achieve the optimum extraction conditions of total polyphenol from Premna microphylla Turcz by response surface methodology.On the basis of single factor tests，the response surface of three factorsand three levels test optimization design method was used to study ethanol concentration，ultrasonic temperature，extraction time these factors'impact on polyphenol yield.The optimum extraction conditions were：liquid to material ratio 40 mL/g，ethanol concentration 52%，ultrasonic temperature 74℃，extraction time 33 min.Under these conditions，the yield of extracted polyphenol could be up to（42.43±1.38）mg/g.
