| 摘 要： | 目的:分析柱果绿绒蒿挥发油的化学成分并进行抗氧化活性研究.方法:采用水蒸气蒸馏法获得挥发油,运用气相色谱-质谱联用进行成分分析,同时运用紫外分光光度计测定其对羟基自由基的清除能力,用酶标仪测定其对1,1-二苯基-2-三硝基苯肼(DPPH)自由基的清除能力,并与2,6--二叔丁基-4-甲基苯酚(BHT)比较.结果:从柱果绿绒蒿的挥发油中鉴定了47个化合物,占其总量的91.866％；挥发油对羟基自由基和DPPH自由基的清除能力均强于BHT.结论:柱果绿绒蒿挥发油的化学成分复杂,主要为十六烷酸(27.653％)和6,10,14-三甲基-2-十五烷酮(16.330％)；其清除自由基的能力显示出良好的抗氧化活性.

| Abstract: | Objective: To study the chemical components of essential oils from Meconopsis oliverana and their antioxidant activity. Method: The essential oil was extracted by steam distillation, and GC-MS analysis was used to identify its constituents. The OH free radical scavenging activity of the essential oils was evaluated with an enzyme mark instrument by assay of the ability of DPPH free radical scavenging. BHT was used as positive control. Result: Forty-seven compounds, account for 91.866% of the essential oils, were identified. The ability of scavenging OH and DPPH radicals of the essential oils is stronger than that of BHT. Conclusion: The main chemical constituents of the essential oils from M. oliverana are n-hexadecanoic acid (27.653%) and 6,10,14-trimethyl-2-pentadecanone(16.330%). And the essential oils showed strong antioxidant activity. |
