Abstract

The aims of this study wereto test the antibacterial activity and chemical composition of various crude extracts of garlic bulbs (Allium sativum).The extract was obtained usingorganic solvent ethanol to extractgarlic bulbs.The extract was prepared and evaluated for antimicrobial activity against sixe bacterial strains by determining minimum inhibitory concentration (MIC). The results revealed that theethanolic extract is potent in inhibiting bacterial growth of both gram-positive and gram negativebacteria. The chemical composition of Allium sativumwas analyzed by gas chromatography/mass spectroscopy (GC/MS).Results of the present study sign the interesting assurance of designing a potentially active antibacterial agent fromAllium sativum.
