A Comparative Study between the Effect of Aqueous and Alcoholic Extracts of Cloves on Inhibiting the Growth of Some Gram-Positive and Gram-Negative Bacteria

Abstract

The clove plant has an influence on utmost microorganisms, that include bacteria whether positive or negative for the Gram stain, as cloves are considered an antibacterial. On this basis, water and alcohol at a concentration of 96% were used as solvents to obtain the aqueous and alcoholic extract at a concentration of 5% and 10%, respectively. In the recent study, 80 samples of Gram-positive and negative bacteria were taken, and 20 samples were used as control. 20 samples of gram-positive bacteria were treated with aqueous extract of the clove plant at a concentration of 5% and 10%. Samples of the same type of bacteria were treated with alcoholic extract at a concentration of 5% and 10%, and 40 samples of negative bacteria were treated with gram stain with aqueous extract of cloves at a concentration of 5% and 10%. Samples of the same type bacteria and treated with alcoholic clove extract at concentrations of 5% and 10%. The study showed the ability of the aqueous extract of cloves at a concentration of 5% and 10% to inhibit the growth of  gram positive bacteria, as well as the ability of the alcoholic extract to inhibit the growth of the aforementioned bacteria. The results were consistent with the ability of the aqueous and alcoholic extracts at a concentration of 5% and 10% to inhibit the growth of Gram-negative bacteria. The ability to inactivate the aqueous and alcoholic extract was observed at a concentration of 10% more than 5% for both Gram-positive and Gram-negative bacteria. The present study reflected the clove plant to have an actual influence against microbes, also with supplementary laboratory studies of the clove plant, it may be one of the antibiotics that will be used in the future to extravagance microbial infections.
