Evaluation of antidiabetic potential of hydroalcoholic extract of Annona squamosa (HAEAS) leaf in alloxan monohydrate induced diabetic Albino rats

ABSTRACT

Background: Diabetes is almost growing health concern worldwide and now emerging as an epidemic world over. Recently, full attention is being paid to the study of natural products as potential antidiabetics. Objective of the study was to evaluate the antidiabetic effect of hydroalcoholic leaf extract of Annona squamosa (HAEAS) plant in alloxan monohydrate induced diabetic albino rats.Methods: Almost a 30 Albino rats with 150- 200 grams weight were weighed and grouped into 5 equal groups taking 6 rats in every group. Group A served as normal control, Group B as diabetic control, received alloxan monnohydrate. Group C and D was received alloxan + HAEAS suspension at 350 and 700 mg/kg doses orally respectively, Group E was given alloxan + standard drug (Glibenclamide 5mg/kg) suspension for 28 successive days and the effect of HAEAS on blood sugar(BS) levels was measured at regular intervals. At the end portion of this investigational research study samples of blood were collected from all rats on 0day (initial), after 72 hrs and after 28th day (29thday) of given test drug HAEAS treatment for biochemical estimation of BS and the BS values were observed.Results: The present research study revealed that HAEAS leaves has antidiabetic effect against alloxan monohydrate induced diabetic rats on i.p. alloxan injection at 150mg/kg.b.w. and confirms that on i.p. alloxan injection causes a significant rise off BS in untreated albino rats when compared to control group. Diabetic rats treatment with HAEAS leaves for 28 days caused dose a dependent fall in BS values. Glibenclamide treated diabetic rats also showed a significant (P <0.00) fall in BS content after 28 days of treatment.Conclusions: This research study confirms that HAEAS leaves has shown significant antidiabetic effect at 350 and 700 mg/kg. b.w. doses in alloxan monohydrate induced diabetic rats.
