Study of the antibacterial activity of the stem bark and leaf extracts of Parkia biglobosa (Jacq.) Benth. on Satphylococcus aureus
AbstractThe antibacterial activity of the stem bark and the leaves of Parkia biglobosa have been tested on four strains of Staphylococcus aureus isolated from patients in the National Hospital Yalgado Ouedraogo – Ouagadougou, Burkina Faso. The tests revealed the efficacy of the hydroalcoholic and the aqueous extracts. They also revealed that the hydroalcoholic extracts were more active than the aqueous extract prescribed by the traditional healers and that the hydroalcoholic extract of the leaves were as active as the bark. The effects of the extracts have been compared to that of the gentamicin, a positive control. The phytochemical screening showed that the extracts of the stem bark were rich in sterols, a triterpenes, tannins, saponosides, anthocyanidins, coumarins, flavonoids and reducing coumpounds. The leaves extracts were rich in tannins, coumarins, anthocyanins, flavones and reducing compounds.
