摘要：
In this work essential oil was extracted from Algerian Rosemary leaves by the supercritical CO2 extraction. The effects of the key parameters such as pressure and temperature on the yield of extraction were examined. The obtained yield were in the range of 0.95-3.52 g of dry oil / g of rosemary, and the best value was obtained at a pressure of 22 MPa and temperature of 40 degrees C. The model of shrinking-core was used to analyse the experimental results of the extraction, this model contains one adjustable parameter, effective diffusivity De, the experimental results were successfully fitted.
