Supercritical fluids have high selectivity thanks to the fact that their solvating power can be varied either physically or chemically. Supercritical carbon dioxide (SC CO2) in combination with silica gel can successfully be applied to fractionate essential oils. By modifying the elution strength of SC CO2 through its density, several essential oils were fractionated, and it was possible to separate compounds of very similar polarity into different fractions. In particular, the essential oils of Mentha × piperita L., Tagetes × lucida L. and Matricaria × chamomilla L. were processed.

Abstract

Supercritical fluids have high selectivity thanks to the fact that their solvating power can be varied either physically or chemically. Supercritical carbon dioxide (SC CO2) in combination with silica gel can successfully be applied to fractionate essential oils. By modifying the elution strength of SC CO2 through its density, several essential oils were fractionated, and it was possible to separate compounds of very similar polarity into different fractions. In particular, the essential oils of Mentha × piperita L., Tagetes × lucida L. and Matricaria × chamomilla L. were processed.
