Fatty acids composition and unsaponifiable matter constituents of bean, cowpea, lentils and lupin crude oils were studied. The results showed that oil content in bean, cowpea, lentils and lupin seeds was 2.11%, 3.45%, 2.72% and 7.72% respectively. Higher percentage of saturated fatty acids was present in lentils oil than in other samples. Palmitic acid was the major saturated fatty acid more in all samples. Oleic acid represents the major unsaturated fatty acid in lupin oil (54.33%) however, linoleic acid represents the major unsaturated fatty acid in bean, cowpea and lentils oils (36.75%, 50.82% and 39.93% respectively). Arachidonic acid was only present in lupin oil (3.83%). The unsaponifiable matter percentages in bean, cowpea, lentils and lupin seed oils were 8.32%, 7.84%, 7.6% and 3.30% respectively. The major hydrocarbon compound in cowpea seed oil was C30, while in lentils and lupin seed oils it was C22. B-sitosterol was the predominant compound in the investigated oils except for lupin seed oil where the predominant one was fucosterol.
