Effect of Sprouting on Antioxidant and Inhibitory Potential of Two Varieties of Bengal Gram (Cicer arietinum L.) Against Key Enzymes Linked to Type-2 Diabetes

Abstract

Type 2 diabetes is a chronic metabolic disease, and the current treatment for type 2 diabetes targets oxidative stress and postprandial hyperglycemia via the inhibition of α-glucosidase and α-amylase, key enzymes linked to type 2 diabetes. In the present study, two varieties of sprouted and non-sprouted Bengal gram (white coated and brown coated) extracts were assayed for total phenolic content, DPPH radical scavenging activity, total antioxidative capability and the inhibition of α-glucosidase and α-amylase activity. Sprouting increased the total phenolic content in both the varieties of Bengal gram and exhibited significant DPPH radical scavenging activity and antioxidant capability compared with that of non-sprouted Bengal gram. Sprouting also increased the inhibitory potential of Bengal gram against α-glucosidase and α-amylase compared with the non-sprouted variety. The overall results suggest that increased antioxidant and inhibitory potential of sprouted Bengal gram against α-glucosidase and α-amylase makes them desirable for dietary management/prevention of diabetes. This finding also provides essential information for the development of sprouted Bengal gram-derived antidiabetic products.
