Abstract

Essential oils obtained from Origanum glandulosum Desf. using supercritical carbon dioxide, micro wavedistillation, hydrodistillation and solvent ethanol were analyzed with GC/MS. The extraction with pressurized CO2 was performed at 15°C and 67 bar. The major valuable component extracted was thymol (63.8, 75.3, 55.6 and 82.4%), respectively, wile The p-cymene and γ-tepinene were revealed only in CO2 extract, microwavedistillation and hydrodistillation (13.7, 6.0 and 12.5%) and (6.8, 8.4 and 11.2%), respectively.
