Abstract
This study investigated the anti-inflammatory effect of hydrophilic and lipophilic extracts from juçara fruits (Euterpe edulis Martius) through measurement of nitric oxide (NOx) and cytokines (IL-12p70, TNF-α, INF-γ, MCP-1, IL-6, and IL-10). J774 macrophages were stimulated with lipopolysaccharides (1µg/mL) and treated with various concentrations (1-100µg/mL) of juçara fruits extracts from crude extracts, and hexane, dichloromethane, ethyl acetate, and butanol fractions. Potential relationships between the phenolic composition of the extracts determined by LC-ESI-MS/MS and their anti-inflammatory capacity were also evaluated. Hexane and dichloromethane fractions inhibited NOx and IL-12p70 while increased IL-10. Hexane fractions also decreased IL-6 and IFN-γ production. Hexane and dichloromethane fractions showed a higher number of phenolic compounds (32 and 34, respectively) than the other extracts tested and were also the only ones that presented benzoic acid and pinocembrin. These results suggest juçara fruits compounds as potential anti-inflammatory agents, especially those of a more apolar nature.
