ABSTRACT

Introduction: Beta vulgaris spp. is popularly known as beets, widely used in ethno pharmacological way to fight various infections of the gastrointestinal tract such as pain, chronic inflammation, and sores on the genitals, inflammation of the ovaries, cramps, kidney problems, heart problems and diabetes.
Objective: to evaluate the antibacterial and modulatory activity of methanol extracts of fruits and hexanic of B. vulgaris against strains of multiresistant bacterial and standards. In addition, to determining the major classes of secondary metabolites such as flavonoids and tannins.
Methods: Hexane and methanol extracts of B. vulgaris were analyzed to antibacterial activity by the broth microdilution test for determination of Minimum Inhibitory Concentration and modulation and aminoglycosides such as amikacin, gentamicin.
Results: the strains relevant of Escherichia coli and Staphylococcos aureus decreased Minimum Inhibitory Concentration of 64 mg/mL and 256 mg/mL thereof when combined antibiotic and extracts. Showing, so a enhancement effect of antibiotic activity, except for the hexane extract in combination with gentamicin against multidrug-resistant strains of Staphylococcus aureus.
Conclusion: in phytochemical were shown the presence of various secondary metabolites, which may explain the bactericidal action of this plant. Therefore, given the results, B. vulgaris spp. is a promising source in combat bacterial resistance.
