SFE of rosemary oil: Assessment of the influence of process variables and extract characterization

The effects of temperature and solvent density on the characteristics of the extracts obtained from supercritical fluid extraction (SFE) of the volatile compounds from Brazilian rosemary ( Rosamarinus officianalis L., Labiatae) using carbon dioxide (CO 2 ) as solvent were investigated. The experiments were performed in a semi‐batch laboratory scale home‐made unit at two temperatures, viz . 310.15 and 320.15 K, over the pressure range of 100‐160...
