| Popis: | Background: Biological activities of medicinal plants make them attractive alternative complementary medicines. Therefore, this study aimed to assess the antioxidant and antifungal activities of the methanol extract of Myrianthus arboreus, Allanblackia gabonensis, Gladiolus quartinianus, Peperomia fernandopoiana and Vepris soyauxii. Methods: Total phenolic contents (TPC) and flavonoid contents (FC) were evaluated using standard methods. The antioxidant activity of the extracts was determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and ferric reducing power assays. Antifungal activity was evaluated by the broth micro-dilution method. Results: TPC of extracts ranging from 67.89 to 196.01 mgGAE/g TPC were very higher in P. fernandopoiana whole plant (PFW) extract (196.01±10.25 mgGAE/g) and MAL (165.71±10.68 mgGAE/g) whereas the A. gabonensis fruit extract (AGF) and M. arboreus bark extract (MAB) had the highest flavonoid content (66.54 ± 2.12 and 48.13 ± 1.65 mgEC/g of extract, respectively). Apart from M. arboreus leave extract (MAL), all extracts showed important DPPH radical scavenging activity (IC50 < 20 μg/mL). AGFl and PFW exhibited significant ferric reducing power compared to ascorbic acid and other extracts (P |
