The phenolic compounds, flavonoids and tanins, were quantified with the reagents Folin-Ciocalteu, aluminium chloride, and vanillin. The chemical profile was performed by HPLC-DAD. The minimum inhibitory concentration was evaluated by the microdilution in a broth method. The antioxidant activity was measured by the capture of free radicals 2,2-diphenyl-1-picrylhydrazyl and 2,2<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:msup><mml:mrow\/><mml:mrow><mml:mo>\u2032<\/mml:mo><\/mml:mrow><\/mml:msup><\/mml:math>-azinobis(3-ethylbenzothiazoline-6-sulfonic acid). In addition, protection against oxidative hemolysis and generation of malondialdehyde were evaluated in human erythrocytes. The composition of the extracts included the caffeic acid, p-coumaric acid, and rosmarinic acid, besides the flavonoids quercetin and luteolin. The EEL showed bacteriostatic action of 1000\u2009<jats:italic>\u03bc<\/jats:italic>g\/mL for all evaluated <jats:italic>Salmonella<\/jats:italic> Typhimurium, <jats:italic>Salmonella<\/jats:italic> Enteritidis, <jats:italic>Pseudomonas aeruginosa<\/jats:italic>, and <jats:italic>Proteus mirabilis<\/jats:italic>, and the EHEB had a moderate antifungal action against <jats:italic>Candida krusei<\/jats:italic> and <jats:italic>Cryptococcus gattii<\/jats:italic> (250\u2009<jats:italic>\u03bc<\/jats:italic>g\/mL). IC<jats:sub>50<\/jats:sub> values of 8.19 (EEL) and 4.51\u2009<jats:italic>\u03bc<\/jats:italic>g\/mL (EEB) in the assay with DPPH and 6.25 (EEL) and 2.87\u2009<jats:italic>\u03bc<\/jats:italic>g\/mL (EEB) in the assay with ABTS were obtained. Up to the 3rd hour of oxidative hemolysis testing induced by AAPH, the EEB and EEL had a protective action, reducing the malondialdehyde. In conclusion, the data indicate that the <jats:italic>O. minarum<\/jats:italic> extracts can be evaluated as bioactive supplies for the development of new drugs for the prevention and treatment of diseases related to oxidative stress and microbial infections.<\/jats:p>","DOI":"10.1155\/2019\/5736919","type":"journal-article","created":{"date-parts":[[2019,4,28]],"date-time":"2019-04-28T19:31:35Z","timestamp":1556479895000},"page":"1-14","source":"Crossref","is-referenced-by-count":16,"title":["Chemical Composition, Antimicrobial Activity, and Antioxidant Activity of <i>Ocotea minarum<\/i> (Nees &amp; Mart.)
