Chemical profile of the volatile compounds from Marrubium cuneatum Banks & Sol

Marrubium cuneatum Banks & Sol. is a perennial plant belonging to the Iran-Turan phytogeographical region, which is distributed in a limited region in the Middle East (Lebanon, Syria, Palestine, Turkey, Iraq and Iran). The chemical composition of the essential oil of Marrubium cuneatum Banks & Sol. (Lamiaceae) from Turkey was characterized. Hydro-distilled essential oil was analysed simultaneously by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS), respectively. A total of 75 components representing 94.7% of the oil were determined; linaool (29.7%), caryophyllene oxide (9.8%), and β-caryophyllene (9.0%) were identified as the major compounds, to the best of our knowledge for the first time from Turkey.
