Potent Antibacterial Activity of Eugenia umbelliflora.

Abstract

The current work describes the antibacterial activity of the crude extract (CE) and some fractions (dichloromethane and ethyl acetate) of fruits and leaves from Eugenia umbelliflora. Berg. (Myrtaceae) against eight pathogenic bacteria. The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) were determined using the agar dilution method. The results showed that almost all the material tested exhibited excellent activity, comparable to the activity of some typical antibiotics, particularly against the Gram-positive bacteria. In summary, the results obtained with this plant extract may be considered very promising, indicating the potential for obtaining new antiinfectious agents against Gram-positive microorganisms.
