The oil of Simmondsia chinensis (Link) CK Schneid (Simmondsiaceae) has been traditionally used in ethnomedicine because of its unique chemical constituents. This study aims to analyze the components of Egyptian Jojoba Oil (JO) and assess the differences between the Egyptian JO and that found in other parts of the world. The fatty acids and sterols profiles will also be determined by Gas Chromatography (GC). Jojoba seeds were subjected to hot extraction by solvent (hexane) followed by cold pressing extraction. Our results showed that the fatty acid Behenic acid methyl ester (C22:0) and Cis-13, 16 Docosadienoic acid methyl ester (C22:2) were in higher percentages within the Egyptian oil compared to JO found in other parts of the world. On the other hand, Egyptian oil was found to have lower percentage of the fatty acids; Eliadic acid, YLinolenic acid, Cis-8,11,14 Eieosatrienoic acid, and Lingocernic acid. Heneicosaoic acid was in much higher percentages within the Egyptian oil and the Egyptian JO does not contain Arachidic, Arachidonic Caprylic, Capric, lauric, Tridecanoic, Myristicor Palmitoleic acid. This study reports novel results clarifying the components of JO cultivated in Egypt under different environmental conditions to our knowledge such results have not been report befor
