Flowers and leaves of pennyroyal (Mentha pulegium L.) were extracted using supercritical CO 2 followed by a two-stage fractional separation technique. Using a ยฏow apparatus with an extraction vessel (1 l) and two separators (0.27 l), the best conditions of extraction (P 100 bar and T 508C) and of se

Ripe fruits of Coriander sativum L. were extracted by steam distillation and by supercritical ยฏuid extraction (SFE), using CO 2 in a two-stage separation system. An inexpensive thermal expansion procedure for supercritical ยฏuid delivery has been developed. The identiยฎcation of components was perform
## Abstract Rosemary oil was extracted by both steam and hydrodistillations then analysed by gas chromatography and gas chromatographyโmass spectrometry. The effect of time of extraction enabled us to follow the evolution of the yield and oil composition obtained by both processes. Copyright ยฉ 2003
