摘　　要：神香草是新疆特有的芳香植物,神香草精油用途广泛,经济价值极高。研究了先用微波处理,再用亚临界萃取技术提取神香草精油的工艺。结果表明:以1,1,1,2-四氟乙烷为萃取剂,在480 W的微波强度下处理2 min,再选择1.5∶1(mL/g)的液料比、0.4 MPa的萃取压力,在45℃下萃取60 min,神香草精油得率可达3.232%,呈淡黄色,香味清新自然。Hyssopus officinalis is unique aromatic plant in Xinjiang,hyssopus oil is widely used,high economic value. Hyssopus officinalis was managed by microwave processing,then extracted by subcritical extraction technology. The results showed that the essential oil yield got to 3.232 % in light yellow and fresh perfume,extracted by the 1,1,1,2-tetrafluoroethane and dealed 2 min inmicrowave intensity of 480 W,then extracted 60 min at45 ℃ with liquid material ratio of 1.5∶1（mL/g）and extraction pressure 0.4 MPa.
