Evaluation of Anti-Diabetic Activity of Zinc Oxide Nanoparticles of Gymnema sylvestre Extract on Wistar Rats

Abstract

Diabetes mellitus is described as a metabolic disorder, which was characterised by high blood glucose levels, which were resulted due to insufficient insulin secretion. There were major complications related to diabetes mellitus. To evaluate the antidiabetic effect of Gymnema sylvestre Zinc Oxide Nanoparticles. Streptozotocin (STZ) of 50mg/kg is used for the induction of diabetes into Wistar rats. The animals were divided into 6 groups. Group-I represented as Control; Group-II represented as diabetic control (STZ ); Group-III represented as 5 mg/kg body weight of glibenclamide + diabetes; Group-IV represented as Gymnema sylvestre extract + diabetes; Group-V represented as 100 µg Gymnema sylvestre Zinc Oxide nanoparticles + diabetes; group-6- Gymnema sylvestre Zinc Oxide Nanoparticles 200 µg + diabetes. The GsZnONPs were inspected to morphological properties using UV spectrophotometer and FTIR. The GsZnONPs shown characterization peak at 300nm. The study has shown that GsZnONPs treated group has shown reduced glucose concentration. The histo-pathological alterations were also studied in all experimental groups. The pathology results of GsZnONPs (200 µg) group has shown the regeneration of islets cells of pancreas. The research study has proved that Gymnema sylvestre ZnO NPs exerts antidiabetic properties.
