     Heavy metal contents and essential oils were estimated in three medicinal and aromatic plants of cupressaceaes (Juniperus thurifera L. var. Africana, Juniperus phoenicea L. and Juniperus oxycedrus L.), frequently used by both infants and adults.

     Samples were collected from different areas in the Atlas Mountains, Tensift Al Haouz of Marrakech (Morocco). The results obtained shown that J. thurifera and J. phoenicea present a high yield of leaf essential oils (1,21 and 0,51%) respectively. Heavy metal contents in the collected samples, i.e. Ca, K, Mg, Mn, Cu, S, Si, Al and Zn, were found at different levels. The highest mean levels of Ca, K, Mg and Si were found in the three species studied.
