Background: Diabetes mellitus is a chronic metabolic condition marked by persistently elevated blood sugar levels. Key digestive enzymes viz. α-amylase and α-glucosidase, hydrolyze consumed carbohydrates into glucose which raises the postprandial blood glucose level in a diabetic patient. So, the development of α-amylase and α-glucosidase inhibitor...

... µg/mL, which is very close to the IC 50 value of standard antidiabetic drug acarbose (539.32 µg/mL) at the same concentration. In contrast, the red dragon fruit peel extract showed lower α-amylase inhibitory activity (52.59 ± 2.78%) in comparison with the red dragon fruit pulp extract with an IC 50 value of 996.05 µg/mL at the same concentration (Fig. 1, Table ...

... activity of bamboo shoots is presented in Fig. (2). Bamboo shoot extracts performed the highest α-amylase inhibition activity (54.04 ± 2.75%), with a calculated IC 50 value of 849.55 µg/mL at the concentration of 1000 µg/mL. This value is well comparable to the level of inhibition performed by acarbose (70.59 ± 2.64%) at the same concentration (Fig. 2, Table ...

... of 1000 µg/mL. On the other hand, turnip shoot extract showed the least amount of α-amylase inhibitory activity (42.48 ± 2.10%) at the same concentration. The computed IC 50 value for turnip shoot and leaf was 1130.75 µg/mL and 1039.76 µg/mL, respectively. Both turnips leaves and shoots showed modest inhibitory ability compared to acarbose (Fig. 3, Table ...
