This review highlights the antimicrobial properties of plant species, showing economic and medicinal value through diverse bioactive compounds.
Amazonian plant species possess a vast potential for antimicrobial action and are the subject of research due to their rich biodiversity and varied bioactive compounds. Among these, Paullinia cupana , Bertholletia excelsa , and Dinizia excelsa stand out. These species are notable for their great ecological, commercial, and economic value in Brazil. This work aims to compile and review scientific studies that provide a comprehensive and updated overview of the antimicrobial potential of three Amazonian plant species. P. cupana is effective against 21 bacterial species, and 81% of guarana seed extracts showed bactericidal activity. B. excelsa is active against Escherichia coli , Klebsiella pneumoniae , Aspergillus sp., and Candida sp., whereas D. excelsa demonstrates activity against Streptococcus mutans . Continuing to investigate the antimicrobial potential of Amazonian species can lead to the development of new drugs effective against resistant pathogens, promoting the conservation and sustainable use of the forest and demonstrating the economic and medicinal value of native plants.
