Background: The aim of this study is to evaluate the antioxidant activity of Guiera senegalensis and Alchornea cordifolia, two plants used in various traditional medicine recipes in Côte d'Ivoire. The methodology consisted of infusion extractions and maceration in a 70% hydroethanol solution. Total phenols were determined using the Folin-ciocalteu reagent, total flavonoids by aluminum trichloride (AlCl3) and tannins by vanilla sulfuric acid (1%). Anti-radical potential was revealed by spectrophotometer.

Results: Total phenols were more concentrated in the 70% A. cordifolia macerate (62.24 ± 0.32 mg EAG/g). Flavonoids were more concentrated in the 10% infusion for both plants (26.12 ± 0.03 mg EQ/g, while tannins were highest in the 5% A. cordifolia infusion (58.69 ± 0.05). Both plant extracts showed good DPPH radical inhibitory power.

Conclusion: Both plants have a high concentration of polyphenolic compounds and good DPPH radical inhibitory power.
