八种植物挥发油的抗氧化活性比较研究

Study on antioxidant activities of eight kinds of plant essential oil

目的:本实验研究了八种挥发油(石菖蒲、香薷、紫苏叶、陈皮、连翘、肉桂、松节油、小茴香)的抗氧化活性,并对其抗氧化活性进行比较,旨在为植物资源的挥发性成分的开发与利用提供科学依据。方法:采用DPPH自由基清除法对八种挥发油进行抗氧化性研究,比较其抗氧化活性。结果:挥发油具有抗氧化活性,且随着浓度的增加,抗氧化能力增强。八种挥发油与阳性对照VE的抗氧化活性比较:紫苏叶>石菖蒲>VE>香薷>陈皮>小茴香>肉桂>连翘>松节油。结论:本研究为植物挥发油在生产生活中的应用及植物资源的开发与利用提供科学依据。

Objective：To provide scientific basis to the development and utilization of essential oils from plants.The antioxidant activitity of Acorus gramineus oil,Elsholtzia stauntoni oil,Perilla Linn oil,Forsythia suspenseoil,Cinnamomum cassia oil,Presl Foeniculum vulgare oil,Pericarpium Citri Reticultae oil,Turpentine were determined and compared. Method：This work compares the antioxidant activity of eight aetheroleas by the DPPH radical-scavenging. Results：all 8 volatile oils have antioxidant activities and are all enhanced with the increace of the concentration. The descending order of antioxidant activity are：Perilla Linn, Acorus gramineus,VE,Elsholtzia stauntoni,Pericarpium Citri Reticultae,Foeniculum vulgare,Cinnamomum cassia Presl,Forsythia suspensa turpentine. Conclusion：This research provides scientific basis in developing and utilizing plants resources.
