Anti-Sickle Cell Anemia and Bacterial Inhibitory Effects of Uvariodendron molundense (Diels) R.E.Fr. (Annonaceae) from Ubangi River Basin, DR Congo

Abstract

The present study was carried out with the aim of evaluating the chemical composition and bioactivity of Uvariodendron molundense against Sickle cell disease and associated pathogenic bacteria agents. The antisickling and antibacterial activities were assessed using Emmel and micro-dilution methods respectively. The results revealed that the leaves and stem bark of U. molundense contains various secondary metabolites such as total phenols, flavonoids, anthocyanins, tannins, quinones, saponins, alkaloids, steroids, terpenoids and leuco-anthocyanins. The n-hexane (non-polar solvent) extract displayed poor yield (0.66) than the extracts obtained in the polar solvents which have a high yield (Methanol: 1.68, Ethanol: 1.46 and Ethyl acetate: 1.40). These results indicate that the abundant secondary metabolites/compounds in this plant species are those which pass easily through the polar solvents (methanol, ethanol and ethyl acetate).
