Our work focuses on the study of the antibacterial activity of essential oil and aromatic
water of plant Cotula cinerea and aromatic water of the Chamomilla recutita L.
Essential oils of aerial parts of Chamomilla recutita and Cotula cinerea were extracted
by steam distillation and test its activity on the four bacterial strains (Staphylococcus aureus,
Escherichia coli, Pseudomonas aeruginosa, Enterobacter cloacae).
The results show that the essential oil has an average Cotula cinerea antimicrobial
activity of inhibition diameters between 6 and 15mm against that obtened by of aromatic
water, the same plant has a weak antimicrobial activity with inhibition zones diameter of
ranging from 5 to 13mm in comparison with the antimicrobial activity of the aromatic water
Chamomilla recutita L., the last one has a significant activity against the same bacterial
strains witch varies between 12 to 15mm.
