An overview of the studies carried out in our laboratories on supercritical fluid extraction (SFE) of volatile oils from seven aromatic plants: pennyroyal (<em>Mentha pulegium </em>L.), fennel seeds (<em>Foeniculum vulgare </em>Mill.), coriander (<em>Coriandrum sativum </em>L.), savory (<em>Satureja fruticosa Béguinot</em>), winter savory (<em>Satureja montana </em>L.), cotton lavender (<em>Santolina chamaecyparisus</em>) and thyme (<em>Thymus vulgaris</em>), is presented.
