Abstract: Saba senegalensis is a plant commonly used in traditional medicine in Korhogo (Cote d’Ivoire) for treating diabetes and renal failure. This study is based on phytochemical screening and evaluation of the antioxidant activity of aqueous, hydroethanolic, and ethanolic extracts of S. senegalensis leaves and stem bark. Phytochemical screening of secondary metabolites using thin-layer chromatography (TLC) revealed the presence of flavonoids, tannins, phenolic acids, saponins, sterols, and terpenes in the plant’s leaf and stem extracts. Coumarins were found only in the leaves, while alkaloids were absent from both organs studied. Antioxidant activity was highlighted in both organs by qualitative and quantitative methods with respect to the DPPH free radical. Quantitative spectrophotometric analysis showed that both leaves and stems possess antioxidant activity. The antioxidant activity of leaves was better than that of stems. Thus, the plant’s leaves and stems could be used as antioxidants capable of preventing and/or treating diseases linked to oxidative stress.
