Hypoglycaemic activity of ethyl acetate fraction of the leaf extract of Telfairia occidentalis.

The leaf of Telfairia occidentalis has been found to possess hypoglycemic or antihyperglycemic effect. The hypoglycemic principle of the leaf is yet to be isolated. The aim of this study is to evaluate the hypoglycemic activity of some fractions of ethanolic leaf extract of Telfairia occidentalis in rat as a step toward activity directed isolation of the hypoglycemic component.
