CO2 is efficient, inexpensive and is a “tunable” solvent. The ability to “tune” the extraction process can not be overstated – especially with a system that will separate constituents during an extraction. You can target specific compounds, like terpenes (terpenoids) through different parameters. CO2 is also a sanitizing agent ...

Liquid–liquid extraction - Wikipedia

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

The BD extraction protocol and that of its associated variants (BDHCl) are probably most efficient due to the approach of the protocol: an initial monophasic ternary solvent extraction that disrupts lipid–cell associations and solubilizes polar lipids, followed by a biphasic system whereby non‐lipids are partitioned out of the extraction phase.
