Abstract
cis-Aconitic acid is a constituent from the leaves of Echinodorus grandiflorus, a medicinal plant traditionally used in Brazil to treat inflammatory conditions, including arthritic diseases. The present study aimed to investigate the anti-arthritic effect of cis-aconitic acid in murine models of antigen-induced arthritis and monosodium urate-induced gout. The possible underlying mechanisms of action was evaluated in THP-1 macrophages. Oral treatment with cis-aconitic acid (10, 30, and 90 mg/kg) reduced leukocyte accumulation in the joint cavity and C-X-C motif chemokine ligand 1 and IL-1β levels in periarticular tissue. cis-Aconitic acid treatment reduced joint inflammation in tissue sections of antigen-induced arthritis mice and these effects were associated with decreased mechanical hypernociception. Administration of cis-aconitic acid (30 mg/kg p. o.) also reduced leukocyte accumulation in the joint cavity after the injection of monosodium urate crystals. cis-Aconitic acid reduced in vitro the release of TNF-α and phosphorylation of IκBα in lipopolysaccharide-stimulated THP-1 macrophages, suggesting that inhibition of nuclear factor kappa B activation was an underlying mechanism of cis-aconitic acid-induced anti-inflammatory effects. In conclusion, cis-aconitic acid has significant anti-inflammatory effects in antigen-induced arthritis and monosodium urate-induced arthritis in mice, suggesting its potential for the treatment of inflammatory diseases of the joint in humans. Additionally, our findings suggest that this compound may contribute to the anti-inflammatory effect previously reported for E. grandiflorus extracts.

Abstract
The leaves of Echinodorus grandiflorus are traditionally used in Brazil to treat several inflammatory conditions, including arthritis. This study aimed to investigate the antiarthritis activity of the 70% ethanol extract of E. grandiflorus leaves and a standardized flavonoid-rich fraction in an antigen-induced arthritis model in mice. Previously immunized mice were treated per os with saline (control group), 70% ethanol extract (100-1000 mg/kg), or a flavonoid-rich fraction (0.7-7.2 mg/kg) 40 minutes before and 3 and 6 hours after the challenge with antigen into the knee joint. The administration of the 70% ethanol extract and flavonoid-rich fraction to mice significantly reduced neutrophil recruitment to the joint cavity and in periarticular tissue. The levels of chemokine (C-X-C motif) ligand 1, tumor necrosis factor-α, and interleukin-1β quantified by the enzyme-linked immunosorbent assay (ELISA) in the periarticular tissue were also diminished in mice treated with the 70% ethanol extract and flavonoid-rich fraction, as well as mechanical hypernociception. Histological analysis confirmed that both the 70% ethanol extract and flavonoid-rich fraction suppressed joint inflammation and inhibited cartilage and bone destruction when compared to the control group. Our results demonstrate, for the first time, that E. grandiflorus has anti-inflammatory activity in an experimental arthritis model and highlights the role of flavonoids in the observed response.
