| 摘 要： | 采用超临界CO2流体萃取法(SFE-CO2)和水蒸气蒸馏法(SD)从川桂叶中提取挥发油,利用气相色谱-质谱联用技术,分析了挥发油的化学组成,并进行了比较.结果表明:两种方法所得挥发油存在较大差别,超临界CO2流体萃取得到挥发油的产率为1.6%,主要成分是香豆素(32.5%),芳樟醇(19.9%),棕榈酸(10.4%),而水蒸气蒸馏法得到挥发油的产率为0.9%,主要成分是芳樟醇(69.0%)、丁香烯(4.6%)、氧化丁香烯(2.7%).

| Abstract: | Volatile oil was extracted from Cinnamomum wilsonii leaves by supercritical CO2 fluid extraction(SFE-CO2) and steam distillation(SD).The chemical components of volatile oil were analyzed by GC-MS and therefore,compared carefully.The experimental results show that there are differences between the volatile oils obtained by these two different ways.The yield of the volatile oil obtained by SFE-CO2 was 1.6%,and the main chemical components are Coumarin(32.5%),Linalool(19.9%),and Palmitic acid(10.4%),while the yield of the volatile oil obtained by SD was 0.9%,and the main components are Linalool(69.0%),Caryophyllene(4.6%),and Caryophyllene oxide(2.7%). |
