The present research was carried out to evaluate the phytochemical constituents of the methanol extracts of Dialium indum leaf, the percentage yield was calculated for the methanol extract comparatively to the chloroform extracts, it was revealed that methanol as an extracting solvent gave a higher yield of Dialium indum extract than chloroform. A total of fifteen and fourteen Phytochemical was determined qualitatively and quantitatively respectively. From the results of the phytochemical screening it were observed that saponins had a higher concentration of 9.240%, the concentration of alkaloids (1.120%), steroids (0.146%), terpenoids (2.345%), flavonoids (0.323%), phenolics (0.142%), tannins (0.581%), cardiac glycosides (1.009%) and cyanogenic glycosides (0.370%) were all determined. The presence of these phytochemicals might be the reason Dialium indum leaf is used as a therapeutic remedy for the treatment of diseases caused by Bacillus typhi, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa, Proteus vulgaris, Salmonella typhi, Staph albus, Staphylococcus aureus, Streptococcus muteus, Aspergillus flavus, Aspergillus niger and Candida albican. The results indicated that the leaf contained Protein (6.887%), Carbohydrate (9.593%), and Oil (47.760%).The results also showed the scientific bases for the use of Dialium indum in herbal medicine and as a source of nutrients for animals. Finally, the study recommends the isolation and purification of these metabolites so as to harness the maximum therapeutic and nutritive potentials.
