3.1. Effect of C. lentillifera extract on DPP-IV and α-glucosidase enzyme inhibition DPP-IV inhibitors stimulated insulin secretion by regulating the release of incretin hormones, whereas α-glucosidase inhibitors decreased postprandial blood glucose by reducing the digestion of carbohydrates[14]. Inhibitory activities of C. lentillifera extract on DPP-IV and α-glucosidase enzymes are shown in Figure 1. C. lentillifera extract inhibited enzyme activity in a concentration-dependent manner, and 1 000 µg/mL of the extract resulted in 46.1% and 42.9% inhibition ofDPP-IV and α-glucosidase activity, respectively.
