Each result represents the mean ± standard derivation (n = 3). Data analysis was performed by one-way ANOVA followed by Tukey’s post hoc test. IC₅₀: inhibitor concentration to inhibit 50% of the activity under the assayed conditions. DPPH: 2,2-diphenyl-1-picrylhydrazyl. RSE: Rytigynia senegalensis extract.
