Volatile oil of wild growing population of Achillea clypeolata Sibth. et Sm. ( Asteraceae ) was studied for yield, composition and antibacterial activity. Eighteen identied components constituted 89.8% of the oil. The major components in the oil were ( E )‐ γ ‐bisabolene (17.9%), 1,8‐cineol (16.0%), borneol (11.9%) and caryophyllene‐oxide (11.5%), together reaching 57.3% of the total oil content. In an antibacterial diffusion assay, the oil showed activity against all tested Gram‐negative bacteria ( Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa ) and Gram‐positive Staphylococcus aureus .
