چکیده

The chemical composition of laurel leaves and fruits essential oils (content of 0.917 and 0.747%, respectively) and laurel leaves extracts obtained at different pressures/temperatures by supercritical fluid extraction (SFE) were studied by GC-MS. The predominant compound in the essential oils and in CO2 extracts obtained at pressures/temperatures of 100 bar/40°C and 250 bar/40°C was 1,8-cineole, but at 100 bar/60°C, α−terpineol acetate was dominant. The extraction yield of SFE increases from 0.68 to 2.54% by increasing the density of CO2 (from 0.29 to 0.88 g/mL).
