Abstract
The chemical composition of the essential oil of Juniperus oxycedrus. from Algeria was studied for the first time. The oil was obtained from the leaves of the plant by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) techniques. The yield of essential oil is 0.1%, based on dry weight. Eighty-nine components representing 82.3% of the total oil were identified. The results show that oxygenated monoterpene (41.0%) composes the major part of oil and the main components are trans.-pinocarveol (7.0%), cis.-verbenol (6.3%), and manoyl oxide (6.0%). A comparison with oils from J. oxycedrus. complex (subspecies and varieties) of other countries reported in literature is discussed briefly.
