Abstract: Essential oils refer to the active components from natural products. The selective extraction and separation of essential oils is of great importance. In this paper, the extraction and separation of essential oils using supercritical fluids was reviewed. The opitmal methods of extraction by using pure supercritical fluid, addtion of co-solvent and the combination of supercritical extraction with other separation technologies such as distillation, adsorption, molecular distillation, double retrograde vaporization, together with the application were also discussed.

摘要： 挥发油是天然产物中一类重要的活性成分。挥发油的选择性萃取与分离具有非常重要的意义。综述了天然产物中挥发油的超临界流体萃取与分离，介绍了单一超临界流体萃取工艺优化，加入夹带剂，超临界流体萃取与精馏、吸附、分子蒸馏、双逆向蒸发等技术联用，及其在挥发油成分选择性萃取与分离中的应用。
