Green synthesis of gold nanoparticles from Fritillaria cirrhosa and its anti-diabetic activity on Streptozotocin induced rats

To evaluate the anti-diabetic effect of Fritillaria cirrhosa gold nanoparticles on Streptozotocin (STZ) stimulated diabetic preclinical models. The albino rats of either sex were equally distributed to five different groups. Group-I represented as Control; Group-II represented as diabetic control (STZ alone); Group-III represented as 10 mg/kg body weight of Fritillaria cirrhosa gold nanoparticles + diabetes; Group-IV represented as 20 mg/kg body weight of Fritillaria cirrhosa gold nanoparticles + diabetes; Group-V represented as 0.1 mg/kg body weight of glibenclamide + diabetes. The animals were killed after the experimental period. The blood and organs samples were gathered and stored for the additional investigations. The gold nanoparticles were inspected via the UV spectrophotometer, HR-TEM, XRD and FT-IR techniques. The bodyweight, kidney and liver weight were tabulated. The food and water consumption were monitored in all the experimental rats. The serum markers, hepatic markers and renal markers were quantified in both normal and investigational rats. The lipid peroxidation and antioxidant status were quantified in the control and experimental rats. The histopathological alterations were also studied in all the experimental animals. The standard drug glibenclamide was used to compare the synthesized AuNPs. The study revealed that the AuNPs treatment restores the serum, hepatic and renal marker in the STZ-challenged diabetic rats. The AuNPs treatment modulates the antioxidants level and decreased the lipid peroxidation by its antioxidant properties. The pathology results revealed that the AuNPs treatment induces the regeneration of islets cells of pancreas in the experimental rats. The research study proved that the Fritillaria cirrhosa AuNPs exerts anti-diabetic properties.
