Antimicrobial Activity of Some Essential Oils and Major Constituents of Essential Oils (original) (raw)

2006, Acta Medica Academica

The screening of the antimicrobial activity of sage, rosemary, eucalyptus, melissa, lavender and thyme essential oils and active compounds 1.8-cineole, citral, linalyl acetate and thymol was conducted by a diffusion test against Gram-positive and Gram-negative bacteria. The most active essential oils, eucalyptus and rosemary oils were tested for the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). The activity was more pronounced against Gram-positive bacteria than against Gram-negative bacteria with MIC ranging from 0.097 mg/ml-0.390 mg/ml, and MBC ranging from 0.390 mg/ml-12.5 mg/ml.
