Abstract
Guettarda (Rubiaceae) is a genus known for its diverse range of bioactive compounds, with demonstrated anti-inflammatory and antioxidant properties. Guettarda uruguensis Cham. & Schltdl., commonly known as ‘jasmim uruguaio’ or ‘veludinho,’ is a native species of the Atlantic Forest that get interested in its potential therapeutic applications. In this study, we evaluated the phenolic content and antioxidant activity of the crude ethanol extract obtained from G. uruguensis leaves (EBGF) and fractions, as well as the antinociceptive, anti-inflammatory, and toxicity activity of the EBGF. Our findings revealed that the EBGF and its fractions contain polyphenolic compounds, including long-chain esters of p-coumaric acid and quercetin, which contribute to their potent antioxidant activity. The EBGF exhibited significant anti-inflammatory and antinociceptive effects, highlighting its potential as a natural product for treating pain and inflammation. Our study supports G. uruguensis as a promising source of bioactive compounds with pharmacological potential.
