NUTRITIONAL, MINERAL CONTENT, PHYTOCHEMICAL, ANTIOXIDANT EVALUATION, AND ANTIMICROBIAL SCREENING OF Pterocarpus Osun LEAF EXTRACT.

Abstract

Pterocarpus osun is an evergreen plant, found in many tropical areas of the globe. The plant parts have been adopted for traditional therapy of many diseases, like sickle cell disorder. This study is to determine the phytochemical, antimicrobial, and nutritional constituents of the leaf extract. The leaf was investigated for its nutritional, mineral properties, antioxidant activity, and biological properties. The powdered leaf was extracted with dichloromethane, ethyl acetate, and methanol successively. Phytochemical analysis of the extracts shows that they contain alkaloids, flavonoids, and terpenoids in dichloromethane extract. Tannins, alkaloids, flavonoids, and terpenoids were present in ethyl acetate and methanol extract. The extracts were tested against staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Salmonella sp, and microorganisms. The mineral composition showed that it contained Ca: Mg: Fe: Mn: K: Na: and Cu: The radical scavenging activities revealed at 0.125mg/ml, the % inhibitory concentration of ethyl acetate extract showed the highest 74.97% as compared with 75.93% vitamin C standard. The investigation revealed the presence of alkaloids, flavonoids, and tannins in all. It revealed the highest quantity of calcium in the leaf extract, the presence of minerals in the leaf can ensure adequate removal of antinutritional.
