Figure 1: Inhibitory effect by ethanol extract of flower (EF) on rat intestinal sucrase, maltase and pNPG hydrolysis (a). Lineweaver-Burk plot of substrate dependent enzyme kinetics on inhibition of rat intestinal sucrase (b), maltase (c) and pNPG hydrolysis (d) activity by EF. α-glucosidase was incubated with different concentrations of sucrose (5-80 M), maltose (1-8 mM) and p-Nitrophenyl-α-D-glucopyranoside (pNPG, 0.25-4 mM) in the absence (control) or presence of EF at IC20, IC40 and IC60 inhibiting concentrations (μg/ml).
