RESUMO

Traditionally, the leaves of Annona muricata L., Annonaceae, are used to treat headaches, fever, toothache, cough and asthma. The decoction of the leaves has parasiticide, antirheumatic and antineuralgic effects when used internally, while the cooked leaves, applied topically, fight rheumatism and abscesses. The aim of this study was to investigate acute and chronic anti-inflammatory potential of an ethanolic leaf extract of A. muricata (AML) in animal models. The ethanolic extract of A. muricata leaf extract was prepared and administered orally to experimental animals used. The anti-inflammatory activity was determined by xylene-induced ear edema in mice and Complete Freund's adjuvant (CFA)-induced arthritis in rats. The results demonstrated that AML is effective for both acute and chronic inflammation. It also significantly attenuated both TNF-α and IL-1β levels in CFA-induced arthritis model. Thus, these results have suggested that AML possesses both anti-inflammatory and anti-arthritic activities. The findings also suggest that AML presents notable anti-arthritic activity that may be mediated by suppressing pro-inflammatory cytokines.
