This study investigated oil extraction from rice bran a by-product of gotten different sources (Afikpo, Abakaliki, and Emene). The was extracted particle sizes (150 µm, 300 420 µm) the using three solvents namely chloroform, petroleum ether, n-hexane at constant time 120 minutes via soxhlet extractor. physiochemical properties were boiling point, saponification values refractive index 77 <sup>o</sup>C, 185.130, 1.334, respectively. Also acid value, surface tension, iodine relative density found to 15.040 g, 6.966×10<sup>2 </sup>N/M, 99.480, 0.779, obtained result based on source revealed that maximum yield 35.05 g achieved Abakaliki chloroform solvent size mm, whereas Emene Afikpo gave 32.62 14.18 oil, respectively same size. Again, highest volume in terms used n-hexane, descending order. physicochemical investigated, showed (RBO) above Nigeria confirms RBO be good quality can utilized many food industries after refining form additives/or industrial purposes as well generation energy.
