摘要:
为筛选具有较强持效性和驱蚊效果的核桃叶片提取物,利用超声辅助水蒸气蒸馏法提取‘温185’‘山核桃’‘美国东部黑核桃’和‘实生核桃’叶片挥发油,以核桃叶片挥发油提取率为指标,在单因素试验的基础上进行正交试验,得出核桃叶片挥发油的最佳提取条件,并结合驱蚊试验,以驱蚊率为指标,筛选4种核桃叶片提取物的最佳驱蚊含量水平。结果表明,超声辅助水蒸气蒸馏法提取‘美国东部黑核桃’叶片挥发油的最佳提取条件为提取时间8 h,超声时间10 min,固液比1∶10 (g·mL-1);在此条件下,核桃叶片挥发油的提取率为0.475%。以无水乙醇为溶剂将4种核桃叶片挥发油提取物溶液稀释为10%、20%、30%、40%并测定其溶液的驱蚊率,‘美国东部黑核桃’叶片挥发油提取溶液在30%含量水平下驱蚊时间可达20 min,此时驱蚊率为85.18%,驱蚊效果最佳。‘美国东部黑核桃’叶片挥发油提取物溶液具有良好的驱蚊效果,具有开发为植物源驱避剂的潜力,可进一步推广应用。
