Distribution mapping and chemical composition of Tetraclinis articulata (Vahl.) masters in the Site of Biological and Ecological Interest of Kharouba (Central Plateau,Morocco)

The main object of this work is to elaborate a distribution mapping of the tetraclinis stands in the sbei of kharouba and explore the opportunities of its valorization to ensure its sustainable and rational exploitation. the results of tetraclinis articulata mapping using the supervised classification of high resolution multispectral satellite image showed that this specie is spread out over the great majority of the sbei kharouba's territory. the study of gas chromatography (gc) and gas chromatography-mass spectrometry (gc/ms) of essential oils (eos) allowed us to identify 5 major components from the sawdust of tetraclinis articulata and 5 major components from the leaves. these components are highly sought after in the international market and are used in various fields: agri-food sector,cosmetic industry and pharmacology. © 2017 university of mohammed premier,oujda morocco.
