AbstractThe aim of this study is to investigate the chemical composition and antimicrobial activities of essential oil of Thymus lanceolatusDesf. (T. Lanceolatus) endemic thyme from Tiaret (province of Algeria). The chemical composition of hydrodistilled essential oil from flowering aerial parts has been analyzed by GC-FID and GC-MS techniques, the antimicrobial activity was realised by agar disc diffusion method and MIC was determined in solid medium by direct contact. Essential oil of T. lanceolataushas been yielded of 2.336 (w/w) based on dry weight, the analyses cited above, led to the identiûcation of 29 components, which accounted for 97.34 % of the total oil. Oxygenated monoterpenes was the main fraction (88.31 %) dominated by thymol (80.2 %) as major component of this oil followed by carvacrol (6.25 %). The oil was found effective against all tested strains especially fungus, except Pseudomonas aeruginosawere low activity observed. In addition Gram (+) bacteria found to be more sensitive to the essential oil than Gram (-) bacteria. This activity was ranging from12±2.65 mm to 60.00±0.00 mm, with the lowest MIC value of under 0.06 mg/ml to 12.53 mg/ml. This results provided the evidence that the studied plant might indeed be potential sources of natural antimicrobial agents. |
