Abstract Sesamum indicum is cultivated worldwide for its edible seed oil. Sesamum indicum which grows up to 100 cm in height is native to Africa and India. Sesamum indicum is used traditionally against habitual constipation, insufficient lactation, intestinal worms and white hair. The oil of this plant is claimed to be useful for liver, kidney and spleen. In this study, Sesamum indicum oil marketed in Khartoum (Sudan) was analyzed by GC-MS. The analysis revealed thirteen constituents dominated by: 9- heptadecenoic acid methyl ester (Z)-(33.70%), 9- octadecenoic acid (Z)-, methyl ester (33.05%), hexadecanoic acid, methyl ester (15.52%) and methyl stearate (12.75%).The oil was evaluated for its antioxidant activity. In the DPPH assay the oil showed weak antioxidant activity.
