Currently, there is a growing interest in identifying alternative sources of fatty acids due to the present increasing demand for oil-rich botanicals in industrial applications. The main objective of this work was to identify the fatty acid compositions of ether extracts of dried leaves of Bryophyllum pinnatum Lam., Ficus exasperata Vahl., Gossypium herbaceum Linn. and Hilleria latifolia (Lam.) H. Walt. The fatty acids were analyzed by gas chromatography with flame ionization detector. Among the evaluated ether extracts, the higher contents of saturated fatty acids were found in H. latifolia (27.96%) with the principal presence of stearic acid compared to the content of the saturated fatty acids in B. pinnatum (0.53%), F. exasperata (0.04%) and G. herbaceum (0.47%). Equally, the result showed that H. latifolia contained the highest percentage of unsaturated fatty acids with the predominant presence of oleic acid with the amount of 41.04%. Linoleic acid was also found to have the highest value in H. latifolia with the amount of 20.41%. Stearic acid, oleic acid, and linoleic acid were found in all the samples. The extract of H. latifolia contained a healthy mixture of different types of fatty acids thus suggesting it as a probable source of suitable fatty acids.
