用GC-MS方法分析薰衣草的化学成分

Study on the Chemical Components of Essential Oil Extracted in Various Ways from the Lavender by GC-MS

利用GC-MS技术分析用水中蒸馏和水上蒸馏提取的薰衣草挥发油的化学成分,共鉴定出20种化合物,其中主要的相同的化合物有6种,分别占相对百分含量的63.03%和75.57%,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。

The compare the main chemical components of both essentiai oils obtained by distilling on water and in water was analyzed and identified by GC-MS. The main components and contents of essentiai 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. That may be the main reason of the distinctness between essential oils of the total antioxidative capacity.
