薰衣草挥发油的抗氧化活性测定和成分比较

利用水中蒸馏和水上蒸馏提取薰衣草挥发油,采用试剂盒法对其抗氧化活性进行测定,应用GC-MS技术测定其化学成分,结果表明水中蒸馏所的薰衣草挥发油的抗氧化能力比水上蒸馏所的薰衣草挥发油的抗氧化能力强,共鉴定出20种化合物,其中主要的且相同的化合物有6种,分别占相对百分含量的63.03%和75.57%,芳樟醇的含量分别占相对百分含量的43.46%和27.06%,这可能是导致不同方法提取的薰衣草挥发油抗氧化能力不同的主要原因。

Study on the antioxidant activity and the chemical components of essential oil obtained from the lavender

The chemical components of essential oils obtained by distilling on water and in water was Analyzed and identified by GC-MS. Mean while the antioxidant was also determinated by the test kit method .The main components and contents of essential oils abstracted in two ways from lavender have large distinctive. This experiment identified twenty components in all, in which six compounds exist in both ways and their relative percentage is 63.03%, 75.57% respectively. The content of the main components, Linalool, is 43.46%, 27.06% respectively. That may be the main reason of the distinctness between essential oils of the total antioxidative capacity.
