ABSTRACT

The present study was designed to investigate the chemical constituents of Sudanese Zea mays seed oil and to evaluate its potential antimicrobial activity. 20 components were detected by GC-MS analysis. Major constituents are: methyl 10-trans-12-cis-octadecadienoate (48.13%) , hexadecanoic acid( 21.60%),9-octadecenoic acid(17.01%), methyl stearate(5.99%) and methyl 18-methylnonadecanoate(2.17%). The antimicrobial activity of the oil was evaluated via cup plate agar diffusion assay against six standard human pathogens(Gram positive: Staphylococcus aureus and Bacillus subtilis; Gram negative : Escherichia coli and Pseudomonasa aeruginosa and the fungi Candida albicans and Aspergillus niger) . Zea mays oil showed good activity against Staphylococcus aureus and the fungus Aspergillus niger.However , it was partially active against other test organisms except Bacillus subtilis.
