Vegetable oils constitute an important part of the diet of humans. The objective of this research is to study the utilizing the seeds of Terminalia bellerica, Moringa peregrine, and tubers of Tiger nut to produce oils that can be utilized successfully as sources of edible oil for human consumption. Fatty acids compositions of oils were analyzed by (GLC), phenolic compounds of oils and meals were identified and determined using HPLC, minerals content of meals were analyzed by atomic absorption spectrophotometer. Also, amino acid content of meals determination by amino acid analyzer. Moringa peregrina seed had the highest oil content (50.09 %) followed by Terminalia bellerica seed (36.01%) and Tiger nut (19.33 %) respectively. Moringa peregrina recorded a higher increase instability compared to the stability of Terminalia and Tiger nut oil. Moringa peregrina seed oil had the highest percentage of oleic acid (76.91%) followed by Tiger nut tubers oil (69.53%), but Terminalia bellerica seed oil had the lowest percentage from it (27. 09 %). Moringa peregrina seed oil contained a higher amount of total tocopherols compared to other samples. The result indicates that Moringa peregrine and Terminalia bellerica, and Tiger nut oil could be a good source of edible oil.
