This study investigated the effect of different extraction solvents on physico-chemical and fatty acid compositions of conophor nut oil (Tetracarpidiumconophorum). Solvent extraction was done using Soxhlet and physico-chemical properties and fatty acid profiles of the oils were carried out using standard procedure. The oil yields of conophor nut oil ranged from 43.77% (ethanol) to 46.72% (n-hexane). The physico-chemical properties values such as iodine num-ber; refractive index; saponification value; acid value; peroxide value; viscosity at 25°C and colour were 23.46-28.31 g I2/100g; 1.52-1.66; 190.90-199.16 mg KOH/g; 2.41-2.62 mg NaOH/g; 3.47 to 4.28 meq O2/g; 11.43-13.98 mPa.; light yellow to deep yellow, respectively. The fatty acid compositions of the oil showed that saturated and unsaturated components ranged from 5.18-7.81% and 83.1-93.13%, respectively. Some of the saturated components of conophor nut oil include palmitic; cerotic; melissic; valeric and tridecyclic while its unsaturated components are oleic; isooleic; petroselinic; linolenic; alpha-linolenic and eicosatrienoic. In conclusion, the results showed that different solvents used in extraction of the conophor nut oil affected some physico-chemical properties of the oil. Similarly, fatty acid compositions were also affected. The properties investigated showed that the oil can find its usage food formulation and chemical industries.
