Antidiabetic activity of methanolic bark extract of Albizia odoratissima Benth. in alloxan induced diabetic albino mice

Objective: To evaluate the antidiabetic potential of methanolic extract of Albizia odoratissima Benth. bark in alloxan induced diabetic mice. Methods: Group-I (normal control) mice received only basal diet without any treatment. In Group-II (Diabetic control) mice, diabetes was induced by alloxan (150 mg/kg i.p.) and received only Tween 80, 5% v/v in normal saline. Group-II and Group-IV mice received metformin (10 mg/kg) and gliclazide (10 mg/kg) as standard drugs. Group-V and VI mice received methanolic bark extract of Albizia odoratissima at doses of 250 and 500 mg/kg body weight p.o., respectively. Results: The results of the study indicates that Albizia odoratissima bark extract significantly (P < 0.01) reduced the blood sugar level. The bark extract also significantly reduced the levels of serum cholesterol, triglycerides, serum glutamic-oxaloacetic transaminase, serum glutamic-pyruvic transaminase, alkaline phosphatase and decreases level of total proteins in alloxan induced diabetic mice. Conclusions: Methanolic extract of Albizia odoratissima has protective effects on the protection of vital tissues (pancreas, kidney, liver, heart and spleen), thereby reducing the causation of diabetes in experimental animals.
