Selective extraction of antimicrobial agents from by supercritical fluid carbon dioxide: phytochemical profile.

The goals of this study were to determine the phytochemical profile of and to evaluate the ability of supercritical fluids (ScFCO) to selectively extract the metabolites responsible for the bioactivity. This species has simple aromatic compounds and lignan monomers, as well as glycerides containing epoxidized saturated fatty acids. Regarding the extraction by ScFCO, the extracts showed a higher antimicrobial activity against human pathogenic strains, with respect to the ethanolic extracts obtained from plant residues after extraction by ScFCO.
