Abstract
The chemical compositions of essential oils from heartwood of the root and stem of Juniperus foetidissima Willd. collected in the vicinity of Eskisehir, Turkey were analyzed by GC/MS. The yield of stem and root heartwood oils were 3.2% and 2.7%, respectively. The main components were found to be cedrol (13–15%), widdrol (9–12%), 8,14- cedranoxide (7–8%), 14-hydroxy-(E)-caryophyllene (5–9%), cis-thujopsene (10–11%) and α-cedrene (6–8%).
