| 摘 要： | 目的]确定超声波提取三白草中总黄酮的最佳工艺条件。方法]以三白草为原料,采用超声波技术提取其中的总黄酮,通过单因素试验研究乙醇浓度、料液比、超声温度、超声时间对总黄酮提取率的影响,通过正交试验对总黄酮的提取工艺进行优化。结果]单因素试验结果表明,当乙醇浓度为60%,超声温度为55℃,超声时间为30min,料液比为1∶30时,黄酮提取率最高;正交试验结果表明,各因素对总黄酮提取率的影响依次为：超声温度〉料液比〉超声时间〉乙醇浓度,总黄酮的最佳提取工艺为：提取溶剂70%乙醇,料液比1∶25,超声温度65℃、超声时间30min,此条件下总黄酮的提取量为6.890mg/g。结论]该研究优化了超声波提取三白草中总黄酮的工艺参数。
