Supercritical Carbon Dioxie; An Efficient Solvent for Herbal Extraction

Journal of Medicinal Plants, 2017
Supercritical fluid extraction (SFE) is an alternative to liquid extraction using solvents. Supercritical fluids can have solvating powers similar to organic solvents, but with higher diffusivities, lower viscosity, and lower surface tension.
