Abstract: Aim of the study: Byrsonima intermedia is commonly used for its antiseptic, antimicrobial, and anti-inflammatory properties in the treatment of diarrhea and dysentery in Brazilian folk medicine. The purpose of this study was to examine the anti-inflammatory activity of the aqueous extract and fractions of Byrsonima intermedia leaves. Materials and methods: rats with carrageenan-induced paw edema and fibrovascular tissue growth, which was induced by subcutaneous implantation of a cotton pellet, were used as acute and chronic animal models of inflammation to investigate the anti-inflammatory effects of the aqueous extract and the individual ethyl acetate (EtOAc) and aqueous fractions of Byrsonima intermedia and catechin. High-performance liquid chromatography (HPLC) was used to determine the fingerprint chromatogram of the aqueous extract and fractions of Byrsonima intermedia. Results: the crude aqueous extract at test doses of 30–300 mg/kg p.o. clearly demonstrated anti-inflammatory effects by reducing carrageenan-induced paw edema, as did the ethyl acetate (100 mg/kg) and aqueous fractions (30–100 mg/kg). In the chronic inflammation rat animal model with fibrovascular tissue growth, the aqueous extract of Byrsonima intermedia (BiAE) at doses of 30–300 mg/kg and the individual EtOAc and aqueous fractions at doses of 30–100 mg/kg and catechin significantly reduced the formation of granulomatous tissue. The presence of catechin and phenolic compounds in the extract and fractions of Byrsonima intermedia was confirmed using HPLC. Conclusion: BiAE and the individual EtOAc and aqueous fractions of Byrsonima intermedia exhibited chronic and acute anti-inflammatory efficacy in rats, which supports previous claims of its use in traditional medicine.
