Tangzhiqing (TZQ), as a potential α-glycosidase inhibitor, possesses postprandial hypoglycaemic effects on maltose in humans. The aim of this study was to investigate the mechanisms by which TZQ attenuates postprandial glucose by interrupting the activity of maltase, including inhibitory kinetics and circular dichroism studies. In this study, we determined the inhibitory effect of TZQ on maltase by kinetic analysis to determine the IC value and enzyme velocity studies and line weaver-burk plot generation to determine inhibition type.
