Securidaca inappendiculata stem extract confers robust antioxidant and antidiabetic effects against high fructose/streptozotocin induced type 2 diabetes in rats. Exploration of bioactive compounds using UHPLC-ESI-QTOF-MS.

Abstract

Diabetes mellitus is the most deadly and most prevalent metabolic disease of contemporary times. This study evaluated the antidiabetic, antioxidant, and pancreato-protective effects of Securidaca inappendiculata extract (SIE) in high-fructose/streptozotocin-induced type 2 diabetes. SIE (50, 100, and 200\u2009mg/kg) was administered to diabetic rats for 8\u2009weeks, thereafter glycaemic parameters, pancreatic β cell function, lipid profile, hepatorenal function, and antioxidant parameters were evaluated in diabetic rats treated SIE. The results indicated that treatment with SIE markedly lowered blood glucose, lipid parameters, hepatorenal function parameters, and lipid peroxidation at the end of the intervention. Additionally, serum insulin levels were significantly increased as supported by restoration of pancreatic β-cell cells in the H&E staining. Moreover, SIE also upregulated serum antioxidant enzyme activities in the treated diabetic rats. The results revealed that SIE possesses potent antihyperglycemic and antihyperlipidemic and antioxidant effects with the considerable restoration of pancreatic β-cells function.
