摘要
从湖南樟树花、嫩叶以及根皮三个部位中提取挥发油,通过GC/MS分析鉴定了其中含量占95%以上的40个化合物。采用ABTS+和LPO两种方法研究了三种精油的体外抗氧化能力,结果显示三种精油均表现较强的清除自由基和脂质过氧化物能力,三种精油清除能力均为根皮>嫩叶>樟花。
In this paper, the phytochemieal components of the essential oils of flowers, young leaves and root-bark from Cinnamomum camphora（ L. ） presl in Hunan, China, were examined by GC/MS,which resulted in the identification of 40 compounds representing 95% of the essential oils. The antioxidant potency of three essential oils were investigated by employing two established in vitro systems ,such as ABTS^＋ and Lipid Peroxides（LPO）. All the three essential oils significantly showed trapping of free radicals, and thereby inhibition of lipid peroxidation. Interestingly, the orders of scavenging activity of different essential oils both were found to be： root-bark 〉 young leaves 〉 flowers.
