Composition of N – Alkanes and Polynuclear Aromatic Hydrocarbons in Jatropha curcas Seed Oil from Different Locations

Abstract:

The hydrocarbon content of Jatropha curcas seed oil obtained from Oleh Community in Delta State, NIFOR farm in Edo State and Ikabigbo in Edo State represented as samples X, Y and Z respectively were investigated using Gas Chromatography with flame ionization detector. The predominant alkanes found in the oil samples are n-Eicosane (C₂₀H₄₂) and n-Docosane (C₂₂H₄₆), while the major polynuclear aromatic hydrocarbon found in the oil samples is chrysene. Sample X has the highest percentage of n-Eicosane (65.72%), sample Y has 35.56% n-Eicosane while sample Z has the lowest n-Eicosane (0.23%). Sample Z has the highest percentage of n-Docosane (91.38%), sample Y has 60.11% n-Docosane with sample X being the lowest (22.65%). The percentage of chrysene in sample Y is highest (100%), sample X has 97.47% while sample Z has the lowest percentage of chrysene (44.75%).
