Jatropha curcas Linn oil was extracted using Hexane : isopropanol mixture in a ratio of 3:2 as a solvent employing the Soxhlet extraction method. The solvent extraction of Jatropha seed kernels gave a yield of 50 g oil / 100 g Jatropha seed kernels. The physical and chemical properties of Jatropha curcas seed oil were evaluated and the results showed that it consists of 50 % (dry w/w) crude oil whose density was 0.9174g/cm3, moisture level of 0.02%, acid value (3.25 mgKOH/g), iodine value (100.62 mgKOH/g), saponification value (195.13mgKOH/g), flash Point (I55°C), Pour point (15°C), sulphur content (0.02%), distillation point (342°C), viscosity at 40°C (33.36 cSt), viscosity at 82°C=11.09 cSt, colour is yellowish (1.0). It is obvious that the properties of Jatropha oil will be comparable to those of the standard diesel oil upon further transesterified to biodiesel.
