NON-COMMERCIALLY EXPLORED Campomanesia spp. NATIVE FRUITS AS POTENTIAL SOURCE OF ANTIMICROBIAL COMPOUNDS

Abstract

Campomanesia eugenioides, Campomanesia xanthocarpa (Berg) and Campomanesia xanthocarpa var. littoralis comprises non-commercially explored native fruits from Brazil. Considering the scarcity of studies on the native fruits characterization from Campomanesia spp., the aim of the present study was to determine the antibacterial effects of C. xanthocarpa (Berg), C. eugenioides and C. xanthocarpa var. littoralis agains 15 strains of food-borne pathogens. The antibacterial tests demonstrated a high antibacterial activity for some of the Gram-positive bacteria tested, i.e., Bacillus cereus, Bacillus subtilis, Listeria monocytogenes, and Staphylococcus aureus. It is noteworthy that C. xanthocarpa var. littoralis fruit extract was the better against a more substantial number of bacteria. Finally, it was possible to report that phenolic and flavonoids compounds present in C. eugenioides, C. xanthocarpa and C. xanthocarpa var. littoralis could be strongly associated with the antibacterial activity observed.
