Aim: To compare the in vitro antibacterial activity of different types of hydroalcoholic extracts of the leaves of the Mangifera indica L. (mango) plant on the strain of Staphylococcus aureus ATCC 6538™. Materials and methods: This study was experimental in vitro and determined the antibacterial activity of four dilutions: Mangifera indica L. ethanol extract (MEE) and Mangifera indica L. hydroalcoholic extract (MHE) at 50% and 100% on cultures of S. aureus ATCC 6538™ comparing with the positive control (chlorhexidine 0.12%) and negative (alcohol 96°) in Mueller Hinton agar cultures using the Kirby-Bauer diffusion method for each study group and incubating the cultures at 37°C for 24 hours. Results: It was found that the 50% and 100% MEE had a smaller size of the inhibitory halo of 21.3 ± 0.5 and 24.1 ± 0.8 mm, respectively. In addition, with respect to the 50% and 100% MHE, it was found that they had a higher antibacterial activity of 24.6 ± 0.5 and 33.5 ± 1.2 mm, respectively. Conclusion: Mango leaf extracts are potent antibacterial, proving 100% MHE to be more effective, thus confirming the presence of active constituents in medicinal plants. Clinical significance: This research has a great clinical applicability due to the opening of research lines that prove the usefulness of these extracts in the therapeutic control of certain oral diseases.
