摘要(Abstract)：

为提高艾草纤维的抗菌效果，应用超声波辅助提取技术从艾草中提取总黄酮，采用单因素实验考察提取时间、提取温度、料液比、乙醇体积分数等条件对艾草总黄酮提取率的影响，采用响应曲面分析法，研究艾草总黄酮的最佳提取工艺。结果表明：乙醇体积分数、料液比及提取温度对总黄酮提取率的影响较大，影响大小顺序为料液比>乙醇体积分数>提取温度，艾草总黄酮提取率随着料液比和提取温度的增加而增大，随着乙醇体积分数的增加先增大后降低；超声波辅助提取艾草总黄酮的最佳工艺条件为艾草粉碎100目、乙醇体积分数50%、提取温度80℃、提取时间20 min、料液比1∶40(g/mL)、提取次数3次，在此条件下艾草总黄酮的提取率可达167.02 mg/g。
