Ripe fruits of Coriander sativum L. were extracted by steam distillation and by supercritical fluid extraction (SFE), using CO2 in a two-stage separation system. An inexpensive thermal expansion procedure for supercritical fluid delivery has been developed. The identification of components was performed by gas chromatography–mass spectrometry (GC–MS). The percentage composition of the 40 identified compounds was compared with the composition of a commercial coriander oil extracted by hydrodistillation.
