Warra AA, Umar RA, Atiku FA, Nasiru A and Gafar MK

Oil extracts from the seed of some selected indigenous cultivars were exploited for physical and phytochemical characteristics and they revealed the following; Oil yields Adansonia digitata seed oil ( 27.37%), Jatropha curcas L seed oil ( 42.19%), Lagenaria siceraria (calabash gourd) seed oil (44.83 %), Luffa cylindrical seed oil (29.03%), Ricinus communis L.(Bean) oil (42.30%), Ricinus communis L.(Wild) seed oil (46.20%), Sesamum indicum L. ( Brown) seed oil (41.67%) . Their colours were Greenish yellow, Lighter green, Light yellow, Greenish light brown, Light brown, Pale amber and Brownish yellow respectively. The following phytoconstituents were found in varying limits; Tannins. Saponins Flavonoids, Alkaloids, Steroids and Terpenoids. The properties exhibited by the seed oils justify their applications in food, soaps, detergents and perfume industries.
