保加利亚产大马士革玫瑰精油的化学成分及其抗氧化活性研究

Chemical Components and Antioxidant Activities of Rose Otto Essential Oil

为研究大马士革玫瑰精油的化学成分及其抗氧化活性,采取气相色谱与质谱联用的方法对保加利亚产大马士革玫瑰精油的化学成分进行了分析,并以总抗氧化活性和羟自由基清除能力为指标,考察其体外抗氧化活性。结果表明,从保加利亚产大马士革玫瑰精油中检测到主要化学组分为香茅醇(45.97%)、香叶醇(22.8%)、正十九烷(14.89%)、正二十一烷(3.74%)等。抗氧化活性测试表明,在实验质量浓度范围内,无论是总抗氧化能力,还是革除羟自由基的能力,保加利亚产大马士革玫瑰精油均表现出良好的抗氧化活性,且一定程度上优于阳性对照药(食品级二丁基羟基甲苯)。

In order to identify the chemical components of rose otto essential oil,GC-MS was used to analyze its chemical components.The antioxidant activity of rose essential oil in vitro was investigated with total antioxidant activity and hydroxyl radical scavenging ability as indicators.The experimental data showed that the main chemical components of rose otto essential oil are citronellol(45.97%),geraniol(22.8%),n-decadecane(14.89%),n-decane(3.74%),etc.The results of antioxidant activity test showed that in the concentration range of the test,both the total antioxidant capacity and the hydroxyl radical scavenging capacity,rose otto essential oil from Bulgaria showed good antioxidant activity,and was better than BHT to a certain extent.
