  ABSTRACT
  The Phoenician juniper, Juniperus phoenicea L. (Cupressales Cupressaceae) fits between steppe formations at low altitudes (coastal dunes) and forest formations. Our work consists in contributing to the study of the phytochemical screening of the essential oils of J. phoenicea collected from two sites: the first in inland Mountains (continental), Djebel Mekther Wilaya of Naama, and the second in coastal area, Stedia Wilaya Mostaganem, in western Algeria. The essential oils of the aerial part of the dried plant, obtained by hydro distillation, revealed significant yields of 0.329% and 0.283%, respectively, Djebel Mekther and Stedia. The results of the GC/MS chromatographic analysis of the two essential oils possess a large chemical variation with 64 constituents representing more than 72.5% for the Stedia sample and 77.3% for the sample of Djebel Mekther, were identified. A comparison was made between essential oil components of J. phoenicea in our two regions and 14 samples from the literature. The Principal Component Analysis (PCA) reveals a significant chemical variability making it possible to define three types of chemical profiles of J. phoenicea and we have a significant dissimilarity between the samples of Djebel Mekther all the other regions.
