Abstract

Essential oils are frequently used for flavour and fragrance in the perfume, pharmaceutical, cosmetic and food industries. They are also suitable raw material for production of new synthetic agents. The antibacterial activity of the essential oils obtained by steam distillation of Rosmarinus officinalis L and Eucalyptus globules collected in south Morocco was studied by micro-atmospheric technique against Escherichia coli CIP54127 and E. coli isolated from urine and resistant to several antibiotics. Both essential oils were effective against the two strains bacteria in particularly against E. coli CIP54127. MIQ of both oils ranged from 60 to 70 ìl for both bacteria. In conclusion, results show that essential oils are effective and could be considered as a natural antimicrobial source that can be used on production of natural antimicrobial agents.
