Abstract:


Background: Treatment of diabetes mellitus (DM) using plant based drugs is advancing and getting much attention in recent years. Cassia auriculata L. is widely used in Indian folk medicine for the treatment of DM. Site-specific targeted plant drug delivery by metallic nanoparticles carriers is a new emerging procedure under research due to its enhanced bioavailability and reduced toxicity. This study was therefore aimed at biosynthesizing a new silver nanoparticle of Cassia auriculata L. flower extract and study its anti-diabetic efficiency in rats.

Methods: The silver nanoparticles were biosynthesized using AgNO3 solution and characterized by spectroscopy, SEM and EDAX analyses. The acute toxicity of this nano-preparation (up to 2000 mg/kg b. wt) was analyzed in rats and the anti-diabetic efficiency (for 50 mg/kg.b.wt and 200 mg/kg.b.wt) was studied in Streptozotocin induced diabetic rats. The diabetic parameters such as; blood glucose, serum protein, liver glycogen, serum lipid profile, serum levels of creatinine, urea, ALT, AST and ALP were analyzed. The histology of the liver, kidney and pancreas was evaluated after staining with Haematoxylin and Eosin.

Results: The increased blood glucose in Streptozotocin induced diabetic rats was found to be significantly reduced (p<0.01) in the treated group of rats. The characteristic damage and disorganization in the cells of Streptozotocin induced DM was found to be recovered in the treated group of rats. The alterations in the lipid profile, hyperglycaemia, reduced serum protein and liver glycogen, enhanced liver function and kidney function markers observed in the rats of DM control group were normalized in the treated group of rats.

Conclusion: The results of this study, proving an efficient anti-diabetic activity of the biosynthesized silver nanoparticles of Cassia auriculata L. flower extract, implies that this nano-preparation may be exploited as an alternative biopharmaceutical agent for treating DM.
