dc.description.abstracttThe extraction of oil from Juniperus communis needles was investigated using supercritical CO2. Theextraction was carried out varying the pressure in the range of 10–30 MPa, the temperature within308–328 K, with a solvent flow rate fixed at 0.42 kg h−1, and a mean particle diameter equal to 0.5 mm orless than 0.315 mm. The operating parameters have been optimized using the response surface method-ology where a second order polynomial expression was used to express the oil recovery, and the resultswere satisfactory. The maximum oil recovery relative to the initial mass was 6.55 wt%. It was obtainedfor an extraction under 328 K, 30 MPa and a particle diameter less than 0.315 mm. Selected samples ofextracts were analyzed using gas chromatography–mass spectrometry (GC/MS) and the results showthat the most concentrated compounds were germacrene D and 1-octadecene.ar
