Background and Aim:The clove, known as Syzygium aromaticum, and the English name Clove, is a plant whose leaves are always green and permanent, and a tree with a size of 8 to 12 meters from the native Mirtaceae family of Malacca Island in eastern Indonesia.Methods:The aim of this study was to investigate the antimicrobial activity of hydroalcoholic extract of clove plant. First, the cloves were powdered and 96% hydroalcoholic extract of clove was prepared with ethanol. The antimicrobial effects of the extract on E. coli and S. aureus were evaluated using antibiogram method and MIC and MBC values of hydroalcoholic extract of clove were determined.Results:The diameter of the non-growth halo of hydroalcoholic extract of clove in the well method on E.coli and S. aureus bacteria was 21 mm and 40 mm, respectively. The results of MIC and MBC in E.coli and S.aureus bacteria were 0.625 mg / ml and 1.25 mg, respectively.Conclusion:These results, introduce the clove extract as an antimicrobial formulation and a suitable alternative to chemical compounds.
