Figure 4: The positions of the best conformation in the active site of alpha-glucosidase (Amber yellow) and the interaction of quercetin (Pink), 3-O-methylquercetin (Light blue), 3,4-dihydroxybenzoic acid (Green) and glucose as a native ligand (Red) from docking experiments. (a) An overlays positions of quercetin, 3-O-methylquercetin, 2,3-dihydroxy-benzoic acid and glucose in the active site of alpha-glucosidase. (b) H bonds (orange line) between quercetin and alpha-glucosidase. (c) H bond (orange line) between 3-O-methylquercetin and alpha-glucosidase. (d) H bonds (orange line) between 3,4-dihydroxybenzoic acid and alpha-glucosidase
