Sample Preparation Using Supercritical Fluid Extraction,d. A major advantage is that by reducing the pressure within the system the supercritical fluid can be allowed to evaporate to give directly a concentrated extract..The application of supercritical fluid extraction (SFE) to medicinal herbs is described with particular reference to the plant feverfew.
