The essential oil of dried leaves of Moroccan and Tunisian Juniperus phoenicea (Cupressaceae) was isolated by direct hydrodistillation (Clevenger-type apparatus) and analyzed using GC (FID) and GC-MS. Forty five compounds in Moroccan oil (72 % of the oil) and thirty one compounds in Tunisian oil (99 % of the oil) were identified. The most abundant compounds in J. phoenicea oils were Opinene (35.46, 38.20 %) and ð-3-carene (7.6, 11.69 %) respectively. Essential oil of Tunisian juniper is characterized by a high percentage of ô-3-carene and limonene with respectively 11.69 %, 10.29 % in comparison to 7.6 % and 1.1 % for the Moroccan juniper. The sesquiterpenes fraction is more abundant in Tunisian juniper with a significant percent of ß-selinene (7.32 %), followed by ß-caryophyllene (4.76 %) and Ot-cubebene (4.15 %).
