This study was designed to designed to evaluate the antidiabetic potential of aqueous leaf extracts of Acacia nilotica in alloxan induced diabetic mice. As the results show, the aqueous leaf extracts of A. nilotica showed antidiabetic activity. The intraperitoneal route of herbal extract administration was found to be more effective than the oral route. Further, qualitative and quantitative phytochemical screening of aqueous leaf extracts of A. nilotica indicated the presence of phenols, alkaloids, flavonoids, tannins and saponins. However, cardiac glycosides and phylobatanins were not detected.
