Study of the Antibacterial Activity of Elettaria Cardamomum Extracts on the Growth of Some Gingivitis Inducing Bacteria in Culture Media

The our work was carried out with an objective to appraisal the antibacterial action of cardamom extracted by four different solvents and prepared in a number of concentrations (50, 100 and 200 mg/mL) toward three different pathogenic bacteria responsible mainly for induce gingivitis infection and comparison their action with the action of antibiotics (Ciprofloxacin (5μg), Ampicillin (30μg) in culture media. The results of phytochemical profiles for different extracts of cardamom showed the presence of alkaloids, glycosides, tannins, and terpenes in all used extracts while flavonoids were present in all extracts except watery extract. Saponins were present only in the ethanolic extract, while phenols were found to be present only in ethanolic and chloroformic extracts. The antibacterial screening of the different extracts of cardamom and standard antibiotics showed various degrees of zones of inhibition in the culture media depending largely upon the type of plant extract, the concentration of extract in addition to the type of tested bacterial. Almost all the cardamom extracts were found to have significant activity (p <0.05) against all tested bacteria com the pared with a negative control. The highest antibacterial potential was observed for the ethanolic cardamom extract, whereas other cardamom extracts showed closed results in general. At the same time, the current study was recorded that inhibition zones diameter against tested bacteria raised significantly (p < 0.05) as the extract concentration raised. The MIC values of watery, ethanolic, chloroformic, and acetonic extracts of cardamom ranged from 0.624 to 1.248 mg/mL, 0.078 to 0.312mg/mL, 0.624 to 1.248 and 0.312 to 0.624 mg/mL against tested bacteria respectively. While the MBC values ranged from 1.248 to 10 mg/mL, 0.624 to 2.5 mg/mL, 2.5mg/mL to 5 mg/mL and 2.5mg/mL respectively.
