摘　　要：就影响超临界CO2萃取效果的诸多因素,如预处理方式、萃取温度、压力、CO2流量、萃取时间、夹带剂、分离压力、温度分别作了系统讨论并整体优化,有助于更好的设计和实施超临界流体萃取实验,获得最佳的超临界流体萃取工艺。This paper systemtically discusses the relationship between the extraction efficiency and the factors such as pretreatment of extracted material, pressure and temperature of extractor or separator, flux of CO2, ex- traction time, entrainer, and so on. This is useful for better organizing SFE experiment and obtaining the optimal SFE parameters of extracted materials.
