The present study was designed to investigate the chemical constituents of Vigna unguiculata (L) Walp. oil and to evaluate its potential antimicrobial activity.. Forty eight components were detected by GC-MS analysis. Major constituents are: 9,12-octadecadienoic acid(49.76%),9-octadecenoic acid(19.30%) and hexadecanoic acid(10.86%) .Some sterols were detected as minor components including : 3-?-9,19-cyclolanost-24-en-3-ol(1.11%) and fucosterol(1.08%).The antibacterial activity of the oil was evaluated by 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) . The oil showed activity against all test organisms. Significant activity was observed against the Gram positive bacteria: Staphylococcus aureus and Bacillus subtilis and the fungus Aspergillus niger .
