The results revealed 17 constituents among which octadeca-9,12,15-trienol (31.1%), hexadenoic acid (30.0%), methyl linoleate (5.7%) and dodecanoic acid (4.6%) bore the largest percentages. The antimicrobial activity of M. obtusifolia oil was studied using the agar diffusion test on 13 strains of bacteria, and against fungus and yeast. The oil showed significant antimicrobial activity against Sthaphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 18739), Listeria monocytogenes (ATCC 9610), Candida albicans (ATCC 13803), Candida tropicalis (LM 37), Candida guilliermondii (LM V70) and Aspergillus flavus (LM 247).
