Abstract
The chemical composition of the essential oil of Juniperus phoenicea from Algeria was investigated for the first time. The volatile oil was isolated by hydrodistillation in yield 0.80% and was analyzed by GC/FID and GC/MS techniques. One hundred and three constituents, representing 96.0% of the oil was identified, twenty-three being reported for the first time in J. phoenicea oil. The oil was characterized by the presence of high amounts of monoterpene hydrocarbons (62.2%) and by a lower percentage of oxygenated sesquiterpenes (8.8%), of which α-pinene (40.2%), α-phellandrene (14.7%) and elemol (3.9%) were the main compounds. Also the oil was characterized by the presence of three diterpenes constituents; manoyl oxide, abietadiene and cis-totarol amounting to 0.3%. A comparison with the composition of the oils of J. phoenicea (subspecies and varieties) of other countries reported in literature is discussed briefly.
