Essential Oil from the Leaves of Ajuga iva: Chemical Composition and Antimicrobial Activity.

The leaf essential oil ofAjuga ivagrowing wild in Mascara region situated in the North West of Algeria, has been obtained by hydrodistillation and analyzed by GC and GC-MS. We proposed to determine the physicochemical, organoleptic and chemical identification of these components. Twenty two volatile compounds were identified which included: dienestrol (54.04%), eucalyptol (27%), o-xylene (7.98 %), 1-octadecanol (5.80%); 3-carene (4.46%), (E)-2,3,6- trimethoxypentafulvene-1-carbonitrile (4.34%), (-)-spathulenol (1.77%), nonanal (1.24%). The oil fromAjuga ivashowed activities againstEscherichia coli, Salmonella typhimurium, Staphylococcus aureus,Bacillus subtilis,andPseudomonas aeroginosa. [ABSTRACT FROM PUBLISHER]
