ABSTRACT

 The chemical constituents of the leaves of Alchornea cordifolia was studied. Phytochemical screening of the leaves extracts revealed the presence of Alkaloids (1.22%), flavonoids ‘L r dihydroxy-7-hydroxyl anthocynidines was isolated from the leave extracts of B. ferruginea. The mineral constituents were calcium (1.60%), magnesium (0.55%), potassium, (0.20%), sodium (0.40%), phosphorus (0.71%), iron (69.00%), manganese (18.00%) and zinc (135.75%). Bridelia ferruginea leaves were found to be rich in vitamins comprising riboflavin (0.16mh/100g), thiamin (6.08mg/l00g), niacin (1,26mg/l 00g,) ascorbic acid (34.32mg/100g). The proximate composition revealed the presence of proteins (2.50%), Ash (7.80%), carbohydrate (52.02%) and food energy (329.90g/cal). The antibacterial assay showed inhibition against proteins mirabilis, pseudomonas aeruginosa, Escherichia coli, klebsiella pneumonia, and staphylococcus aureus. These results authenticate the use of the plant for the treatment of infection and disease in Nigeria. anthocyanidine 7-0-p-D-diglucopyranoside was isolated from the leave extracts of A. cordifolia. The mineral constituents identified in the plants were calcium (1.80%), magnesium (0.67%), potassium, (0.58%), sodium (0.18%), phosphorus (0.43%), iron (140.50%), manganese (8.25%) and zinc (85.75%). Alchornea cordifolia leaves were found to be rich in vitamins comprising riboflavin (0.26 mg/lOOg), thiamin (6.18mg/100g), niacin (0.24mg/100g), ascorbic acid (28.16mg/l00g). The proximate composition revealed the presence of proteins (18.99%), ash (4.80%), carbohydrate (65.91%) and food energy (354.90g/cal). The antibacterial assay showed inhibition against proteins mirabilis, Pseudomonas aeruginosa, Escherichia coli, klebsiella Pneumonia, and Staphylococcus aureus. The chemical constituents of the leaves of Bridelia ferruginea was also studied. Phytochemical screening of the leaves extracts revealed the presence of Alkaloids (1.46%), flavonoids (1. 84%), tannins (0.50%), phenols (0.06%) and saponins (1.69%).
