Gas chromatography/mass spectrometry in aroma chemistry: a comparison of essential oils and flavours extracted by classical and supercritical techniques

Abstract

Gas chromatography/mass spectrometry has been used as an analytical method for the determination of the composition of the essential oils of lavender, basil, clove and ginger extracted by means of a supercritical fluid extraction plant. These data, compared with those obtained analysing the same essential oils extracted by means of more classical techniques, i.e. steam distillation and liquid extraction, prove the effectiveness of supercritical fluid extraction in aroma chemistry. © 1997 John Wiley & Sons, Ltd.
