ABSTRACT
The extraction from natural sources is the most widely studied application of supercritical fluids (SCFs), and several hundred scientific papers on the topic have been published and reviewed [1-9]. Indeed, supercritical fluid extraction (SFE) has immediate advantages over traditional extraction techniques; it is a flexible process due to the possibility of continuous modulation of the solvent power/selectivity of the SCF, and it allows the elimination of polluting organic solvents and of the expensive postprocessing of the extracts for solvent elimination.
