摘要： 为探讨采用超临界CO2萃取技术萃取大蒜精油的工艺条件及分析其组成 ；研究了超临界CO2萃取大蒜精油时，萃取压力、萃取温度、CO2流量和萃取时间对大蒜精油萃取率的影响，并采用气-质联用方法（GC-MS）分析了大蒜精油的组成。结果表明: 最佳萃取条件为萃取压力30Mpa、萃取温度45℃、CO2流量10kg/h、萃取时间80min；GC-MS分析确定了大蒜中24种化学成分,其中含量较高的为含硫化合物。

Abstract: To discussion the extraction technology of garlic essential oil by supercritical fluid and to analysis the compositions of garlic essential oil ,the effect of extraction pressure, temperature, flow rate and time on essential oil yield were studied. Moreover , the components of essential oil were also analysised by GC-MS. The results were as follows: the optimum extraction pressure, temperature ,CO2 flow rate, extraction time for the extraction were 30Mpa, 45℃,10kg/h and 80min, respectively.24 components which most of them were surfur-containing compounds were found in garlic by GC-MS method .
