Physico-chemical properties of four Nigerian seeds namely: Poga oleosa, Ricinus communis L. (Castor seed oil), Butyrospernum parkii (shea butter), and Hevea brasilensis (rubber) seeds were extracted for its oils with six solvents: chloroform, ethanol, hexane, carbon tetrachloride, pet-ether and water were investigated using standard techniques. The oils were characterized for the following parameters: saponification value, unsaponifiable matter, iodine value, acid value, peroxide value, ester value, viscosity, refractive index, specific gravity, pH and moisture content. The results obtained for the tested parameters suggest that the oils investigated in this study have potential industrial applications such as in the manufacture of paints, soaps and hair products.
