Abstract
The chemical study of the essential oil extracted from leaves of Juniperus phoenicea growing in Morocco has been carried out. The main components of J. phoenicea oil were the monoterpene hydrocarbons α-pinene (45.5%) and ω-3-carene (13.0%). Our results show a number of differences in composition with respect to a previous study of the leaf oils of J. phoenicea (Greece and Spain).
