As of recent, solvent extraction using different solvents has been found to be the most efficient method of extraction. Previously, in solvent (Soxhlet) extraction, a narrow spectrum of solvents had been put to use in extraction, with hexane being the most popular and widely used choice solvent. Hence, the use of various extraction solvents in this research work is to show that hexane could be replaced with other solvents. Additionally, Solvents were combined in different combination ratios to show that oil yield could be improved by solvent combinations as opposed to using only single solvents. From the results obtained, it was ascertained that solvent combinations actually improved oil yields since the highest oil yields were obtained from the combination of Petroleum ether (100ml), Hexane (50ml) and methanol (50ml), having 50.667% and 51.33% with the combination of Hexane (100ml) and Methanol (100ml) as opposed to when only petroleum ether was used yielding 40.667%. Therefore, the results obtained from the investigation suggests that solvent combination could prove as an adequate replacement and alternative to the use of single solvents in solvent extraction. © IAEME Publication.
