Abstract
In this study, we investigated the effect of environmental conditions on the composition in fatty acid and the yield of argan oil of seeds from seven locations following an increase of aridity gradient; Essaouira, Tamanar, Imouzzer, Admine, Ait Baha, Merght and Bouizakarne. Indeed, the analysis of the composition of argan oil showed that the saturated fatty acids varied in the same way in the fruits of the studied plants. Therefore, oleic acid increased with altitude and linoleic acid decreased with aridity. Moreover, no significant differences were found on oil yield of the studied areas. Furthermore, we compared the antioxidant activity of alimentary and cosmetic oil. The results showed that alimentary oil had the highest antioxidant capacity compared to cosmetic oil.
