Abstract: The oil extract of G. scabra seeds was analyzed for its antibacterial, chemical and physical properties. Physical and chemical properties analyzed included moisture content (0.91%), acid value (13.65%), iodine value (132.27), peroxide value (18.58), saponification value (191.03), free fatty acids (6.86%) and density (0.87g/cm3). The oil was found to inhibit the growth of Staphylococcus aureus (SA), Escherichia coli (EC) and Salmonella typhi (ST) at an MIC of 50%. However, there was no effect on Shigella sonnei (SS). The fatty acid composition of the extracted oil was revealed using the Gas chromatography Mass spectrometry (GC-MS) method. A total of 18 components of the oil were identified. Oleic acid (27.07%), 10- undecenoic acid (19.99%), palmitic acid (10.56%) and stearic acid (6.22%) were detected as the dominant fatty acids in the G. scabra seed oil.
