| 摘 要： | 目的:提取野生大叶三七柄梗中的挥发油,分析其挥发油中的组分,探讨其挥发油的生物活性,为开发利用这一资源提供科学依据。方法:用水蒸气蒸馏法从大叶三七柄梗中提取挥发油,用气相色谱-质谱联用技术对其挥发油组分进行分离和结构确定,对大叶三七柄梗挥发油进行抗氧化和抗菌实验研究。结果:从大叶三七柄梗挥发油中鉴定出43个组分,占全油的96.12%,大叶三七柄梗挥发油有明显地抗氧化活性和抗菌活性。结论:大叶三七柄梗挥发油中含量较高的组分是2,6-二特丁基苯酚(20.99%),新植二烯(15.06%),降姥鲛-2-酮(6.60%),斯巴醇(4.26%),α-紫罗兰酮(4.02%)等。大叶三七柄梗挥发油对·OH有明显的清除作用,大叶三七柄梗挥发油对实验菌株均有明显的抑制和灭活作用特别是对大肠埃希菌CMCC44113和白色假丝酵母菌CMCC850216株的作用表现得更为显著。
