Evaluation Of Hypoglycaemic Effect And Phytochemical Constituents Of Methanol Extract Of Vernonia Amygdalina Del Fam. (asteraceae)

ABSTRACT Leaf of Vernonia amygdalina has been shown to have hypoglycemic activity. This may be as a result of the presence of secondary metabolites as its constituents. The major secondary metabolites present in the leaf are tannins, carbohydrates, reducing sugars, glycosides, steroids and proteins. This work was designed to identify these secondary metabolites responsible for this activity, test the lethality of the constituents and then determine the best solvent for extraction. A 1 kg crushed leaves of the plant Vernonia amygdalina was extracted with methanol using soxhlet apparatus. The d…
