In the present
time, drug resistance in microbes is a very serious problem. Essential oils and other extracts of
plants have evoked interest as sources of natural products. They have been
screened for their potential uses as alternative remedies for the treatment of
many ailments. In the present study,
the in vitro antibacterial activity of the essential oils from ten
aromatic plants Thymus fontanesii, Thymus
vulgari,Mentha pulegium, Eugenia
caryophyllata, Origanum vulgare, Laurus nobilis,
salvia, Geranium, Lavender and Cinnamomum
aromaticum was investigated. The oils compositions were characterized by
gas chromatography/mass spectrophotometrical analyses. The antibacterial
activity of these oils were tested against seven pathogenic bacteria: Pseudomonas aeruginosa ATCC 27853, Escherichia
coli ATCC 25922, Staphylococcus
aureus oxaR ATCC 43300, Staphylococcus aureus oxaS ATCC 25923, Staphylococcu aureus ATCC 33862, Bacillus cereus ATCC 11778, Bacillus
subtilis ATCC 6633; by using the agar incorporation method to determine the Minimum Inhibitory
Concentration (MIC) of each oil. The results have shown a greater antibacterial
effect of all essential oils
samples against Gram positive than the Gram negative bacteria. Pseudomonas
aeruginosa was the only bacterium not susceptible to Laurus nobilis, salvia, geranium, lavandre,and Mentha
pulegium oils. The highest and broadest activity was shown by Cinnamomum
aromaticum oil. These results suggest that these essential oils may be
alternative natural source medicine to prevent and treat many bacterial
diseases.
