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.
目的
研究多刺绿绒蒿挥发油的化学成分及其抗氧化活性。
方法
采用水蒸气蒸馏法提取挥发油，通过气相色谱-质谱联用（GC-MS）分析鉴定其成分。采用酶标仪通过测定二苯基苦味酰基自由基（DPPH）清除能力来评价挥发油对羟基自由基（OH）的清除活性。以二丁基羟基甲苯（BHT）作为阳性对照。
结果
鉴定出47种化合物，占挥发油总量的91.866%。挥发油对OH和DPPH自由基的清除能力强于BHT。
结论
多刺绿绒蒿挥发油的主要化学成分是正十六烷酸（27.653%）和6,10,14-三甲基-2-十五酮（16.330%）。且该挥发油表现出较强的抗氧化活性。
