| 摘 要： | 通过正交试验,讨论了超临界CO2萃取大活(Angelica dahurica Benth. et Hook)籽挥发油过程中萃取压力、温度、时间对萃取率的影响,同时将试验结果与水蒸汽蒸馏法所得结果进行了比较,并采用气质联用(GC-MS)方法对比分析了超临界油与水蒸汽挥发油的成分.结果表明:超临界萃取压力的变化对萃取率的影响最大,萃取温度次之,而萃取时间最小.从GC-MS分析结果看,超临界CO2萃取大活挥发油的萃取率较水蒸汽蒸馏法高,最佳萃取条件为:萃取压力30MPa,萃取温度45℃,时间2h,挥发油收率为2.78%.

| Abstract: | An experiment was conducted to extract essential oil from the seeds of Angelica dahurica Benth.et Hook by supercritical carbon dioxide fluid extraction technology.The effects of extraction pressure,extraction temperature,and extraction time on extraction rate of essential oil were discussed by orthogonal experiment.The extraction rate of essential oil by supercritical fluid extraction was compared with that by water vapor distillation,and the components of essential oil were also compared by gas chromatogra... |
