Abstract
This study was conducted to test in vitro the effect of active materials that extracted by cold and boiled water, in addition to the extraction by different organic solvents , i.e. Ethyl Alcohol ; Hexan and Ethyl Acetate for the leaves of Thyme plant on inhibition growth of Staphylococcus aureus for its importance due to the causes of numerous diseases .Results showed from the preliminary chemical (filtration) test that, the extracts of thyme leaves contain, phenols and terpens, but without alkaloids, the active groups from alcoholic extracts were also seperated and its inhibition activities were tested against S. aureus. This study proved that, the aqueous extract and aqueous part of alcoholic extract produced an inhibition effect of 6.25 mm in diameter for both extracts, while, the bicarbonate part of alcoholic extract was the most effective in inhibition diameter, of 11.65 mm.The study also showed that, the minimum inhibition concentration of the bicarbonate part of alcoholic extract was 12.5 mg/ml growth of S .aureus. while, the minimum bactericidal concentration was 25 mg/ml .
