Cytoprotective and anti–inflammatory effects of kernel extract from Adenanthera pavonina on lipopolysaccharide–stimulated rat peritoneal macrophages

ObjectiveTo investigate mechanism of anti–inflammatory activity of Adenanthera pavonina (A. pavonina) extracts.MethodsRat peritoneal macrophages were treated with different concentrations of lipopolysaccharide and H2O2 in the presence and absence of kernel extract from A. pavonina. Nitric oxide, Superoxide anion generation, cell viability and nuclear fragmentation were investigated.ResultsThe pre–treatment of kernel extract from A. pavonina suppressed nitric oxide, superoxide anion, cell death, nuclear fragmentation in lipopolysaccharide and H2O2 stimulated or induced macrophages, respectively.ConclusionsThese results suggest that A. pavonina extract suppresses the intra cellular peroxide production.
