Values are reported as mean ± S.D. of three parallel experiments. Aq: Tambourissa peltata Baker aqueous extract; TP-EA: T. peltata ethylacetate extract; TP-MEOH: T. peltata methanolic extract; TE: Trolox equivalent; EDTAE: EDTA equivalent. Different letters (a–d) indicate significant differences between the tested extracts (p < 0.05).
