    To determine the effect Kigelia africana fruit extract has on blood glucose levels of diabetes mice and its phytochemical profile Mice were induced with diabetes using Alloxan monohydrate 90mg/kg. Blood glucose was checked before induction and 72 hours after induction to confirm diabetes. Treatment involved using oral administration of Kigelia fruit extract 1000mg/kg, Kigelia fruit extract 500mg/kg, Glibenclamide 0.25 mg/kg, Kigelia fruit extract 500mg/kg and Glibenclamide 0.25mg/kg and Normal Saline.The results showed a greater reduction in blood glucose of mice after treatment with Kigelia extract 1000mg/kg compared to Kigelia 500mg/kg [(5.3 +/- 0.5mmol/l) vs (6.3+/- 0.6mmol/l), (p= 0.005)]. Further, Glibenclamide 0.25mg/kg showed less reduction in blood glucose than Kigelia 1000mg/kg [(7.4+/-0.9mmol/l) vs (5.3 +/- 0.5), (p= 0.00)]. The mean blood glucose levels were lower in mice that received Kigelia extract than those that received both Kigelia extract and Glibenclamide [(5.3 +/- 0.5mmol/l) vs (7.8 +/- 0.6 mmol/l), (p=0.00)]. The fruit extract tested positive for Tannins, Saponins, Flavanoids, Alkaloids, Glycosides and Steroids. Findings of this study indicate that Kigelia africana fruit extract causes reduction in blood glucose of diabetes induced mice and gives better results when used alone than in concomitant use with Glibenclamide. The study also indicates that the fruit extract has alkaloids, saponins, steroids, glycosides, tannins and flavonoids.
