Each result represents the mean ± standard derivation (n = 3). Data analysis was performed by one-way ANOVA followed by Tukey’s post hoc test. BHA: butylhydroxyanisole. IC₅₀: inhibitor concentration to inhibit 50% of the activity under the assayed conditions. ABTS: 2,2-azino-bis-3-ethyl benzothiazoline-6-sulphonic acid. RSE: Rytigynia senegalensis extract.
