IL-6 quantification. Measurement of IL-6 in supernatants of peritoneal macrophage cultures stimulated by LPS, treated with 100 μM dexamethasone or (A) hydroalcoholic extract, (B) hexane fraction, (C) dichlorometane fraction, (D) ethyl acetate fraction and (E) aqueous fraction, obtained from Euterpe oleracea (EO) seeds. Data represents the mean ± standard deviation of the experiment performed in triplicate. #p < 0.001 compared to the group without stimulation or treatment (white column); ∗∗p < 0.01, ∗∗∗p < 0.001 when compared with the LPS-stimulated and untreated group, after Brown–Forsythe analysis and Welch, followed by Dunnett's T3 multiple comparison tests.
