Oil quality characteristics of Cultivars sinnensis and Citrullus lanatus seed oils were investigated using standard techniques. The physico-chemical analysis revealed the colour to be (yellow, reddish brown), specific gravity (0.92 ± 0.01, 0.94 ± 0.02), pH (3.88, 5.21), acid values (82.00 ± 2, 93.18 ± 1 mg KOH/ g), iodine values (108.00 ± 3, 103.61 ± 2 mg iodine/ g), peroxide values (22.84 ± 1, 30.00± 1.5meq/ kg) and saponification values (192.00 ± 1, 208.50 ± 3 mg KOH/g) respectively. These properties indicate that the oils will be very useful industrially for the manufacture of products such as paints, liquid soaps and shampoos. The four most abundant fatty acids were; C18:26 > C18:19 > C16:0 > C18 : 0 in the two oils. Unsaturated fatty acids predominated in the sample with adequate amounts of essential fatty acids.
