NOGUERA MACHADO, Nirza et al. Antibacterial properties of Mangifera indica L. seeds extracts on methicillin-resistant Staphylococcus aureus. Arnaldoa [online]. 2021, vol.28, n.1, pp.109-114. ISSN 1815-8242.  http://dx.doi.org/10.22497/arnaldoa.281.28105.

The “mango” tree (Mangifera indica L.) have been use in traditional medicine for the treatment of different ailments. Is a known that diversity extracts of various parts plants have activity microorganism pathogenic. In this work were investigated the antimicrobial activity of mango seeds extract against Staphylococcus aureus methicillin-resistant strains (MRSA) 1025 and 1920. The seeds extractions prepared by maceration whit ethanol 90%. The phytochemical constituents of extracts were characterized for total phenol content (TPC) and total flavonoids (TF). Antibacterial activity of extracts were determined using disk diffusion, agar dilution methods. The results showed that the seeds extracts contents higher to TPC (85.60 ± 2.13 mg EAG/g of extract) and TF (49.32 ± 1.12 mg CE/g of extract). The result revealed that the extracts possess good antibacterial activity against S. aureus MRSA 1025 and 1920, the inhibition zones ranged from 6.0 mm to 19 mm, at different concentration extracts probed. The results probed that the mango seed extract contained many compounds such as phenolic that could be affect bacteria S. aureus MRSA, and these bioactive compounds to be isolated for the production of new antibiotics.

Keywords : S. aureus MRSA; “mango”; Mangifera indica; natural antimicrobial.
