Supercritical Fluid Extraction of Essential Oils - Results of Joint Research

Popis výsledku v původním jazyce

Peppermint, thyme, and sage herbs and yarrow flowers were extracted with supercritical and liquid carbon dioxide at the pressure 9-13 MPa and the temperature 25-60 oC., Two extraction periods were clearly distinguished. Almost pure essential oil was extracted in the first, fast period. The extraction was then retarded, and waxes and water prevailed over the essential oil in the extract collected in the second period that was controlled by essential oil-matrix interaction. To demonstrate how the interaction affects the extraction of essential oils from seeds, thermodynamic modelling of limonene+vegetable oil+CO2 equilibrium was applied. Compared to hydrodistillation, the extracts contain less monoterpenes due to the low efficiency of their collection incooled trap, but the yield of diterpene manool was, compared to hydrodistillation, more than twofold. The extraction of sage essential oil carried out at 9-13 MPa and 25-50 oC was most efficient at 13 MPa and 50 oC.
