Phytochemical screening and medicinal attributes of crude extracts of soyabean (glycin max) and black-eyed bean (phaseolus vulgaris) leaves

Soyabean (Glycin max) and black-eyed bean (Phaseolus vulgaris) belongs to the family of leguminosae and are grown in West Africa especially Nigeria for its edible seeds and leaves. Phytochemical screening of the leaves obtained by the cold maceration method using 95% ethanol, petroleum ether (60-80°C), and water extracts of leaves revealed the presence of alkaloids, flavonoids, glycosides and tannins. The growth of Salmonella typhi; Klebsiella pneumoniaae; Escherichia coli, Aspergillus funugatus, Mucor mucedo and Rhizopus stolonifer from the extracts and the growth was inhibited. Ethanol and aqueous extracts of Glycin max showed appreciable inhibitions to the growth of Mucor muced and minimum inhibitory concentration was 20% for all extracts
