The essential oil of T.ammi, and extracts of T.ammi fruits with organic solvents, displayed remarkable anti-bacterial effects against Bacillus subtilis, Pseudomonas aeruginosa, Salmonella typhimurium, Enterobactor aerogens and Staphylococcus aureus. The hydrodistilled ground fruits give a pale yellow colored oil (2.3% w/w), which found to contain 30 different compounds. The major components were thymol (49.6%) and cymene (16.3%). Minor components were eugenol (3.0%), β-pinene (2.5%), oleic acid (2.3%), verbenol (1.8%), terpineol (1.3%), myrcene (1.0%), camphene (1.0%), D-limonene (1.0%), ocimene (0.7%), linalool (0.6%), carveol (0.5%), apiole (0.4%), α-thujene (0.2%), and α-selinene (0.1%).
