Abstract
A dry, whole plant of Vernonia ambigua Kotschy and Peyr was collected from Suleja, Niger State, Nigeria and qualitatively screened for the presence of secondary metabolites using standard methods. Some proximate compositions were also determined. The result showed the presence of alkaloid, tannin, saponin, flavonoid and carbohydrate while terpene, sterol, anthraquinone, phlobatannin, resin, cardiac glycoside, balsam, phenols and volatile oil were not detected. The result of proximate analysis which includes ash value, acid-insoluble ash value, water and alcohol extractive values are reported. Crude extracts of the plant were screened for activity against selected microorganisms. The result is also reported. This work is aimed at providing some scientific data for this plant since there is limited scientific report on it in literature.
