Chemical Composition, Organic and Mineral Contents of Leaves of<i>Tetraclinis articulata</i>(Vahl) Masters. From the Tensift- Al Haouz, Marrakech region (Morocco)

Abstract

Abstract The chemical composition of essential oils obtained by steam- distillation of the leaves of Tetraclinis articulata were studied by GC-FID and GC-MS. The samples were collected from Tensift Al Houz region from Marrakech (Morocco). Monoterpenes hydrocarbons constituted the main chemical groups in the oil from leaves of T. articulata contained higher amounts of α-pinene (41.2 %) and bornyl acetate (20.6 - 36.4 %). 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 this specie. The composition of organics (lipids, total nitrogen, protein and fats) of this specie is also reported.
