Antidiabetic activity of Annona squamosa Linn. in alloxan ‑ induced diabetic rats

Ranveer Singh Tomar, Siddharaj Singh Sisodia


Background: Diabetes mellitus is characterised by rise in blood sugar levels resulting from insulin dysfunction or insulin insufficiency.
Aim: The aim of the present investigation is to evaluate antidiabetic activity of hydroalcoholic extract of Annona squamosa Linn (A. squamosa Linn) in alloxan‑induced diabetic rat model. Materials and Methods: Diabetes is induced by a single‑dose intraperitoneal injection (i.p.) of alloxan (120 mg/kg) to albino rats. Results and Discussion: Treatment with A. squamosa Linn. extract at a dose of 350 mg/kg and 700 mg/kg and glibenclamide at a dose of 5mg/kg for 28 days, after induction of diabetes by alloxan, caused significant
reduction in blood serum glucose and serum lipid profiles like total cholesterol and triglycerides but significant increase in body weight and serum high density lipoproteins (HDL) level in diabetic rats compared to untreated group. Histological study of the pancreas of diabetic rat treated with A. squamosa extract also showed partial regeneration of beta cells. The antidiabetic activity of this extract is found comparable to glibenclamide. Thus, leaves of A. squamosa Linn. can be used as potential antidiabetic drug.
Key words: Annona squamosa, antidiabetic, glibenclamide
