摘要：

Phloridzin is a chalcone with potential application in functional food and medicine. In this study, the alpha-glucosidase inhibitory mechanism of phloridzin was investigated by inhibitory test, fluorescence spectroscopy and molecular docking method. The IC50 value of phloridzin was determined at 0.68 mmol/L. With the increase of phloridzin concentration, the static fluorescence quenching of alpha-glucosidase could be observed. The quenching constant (Kq), binding constant (K-A) and the number of binding site (n) of phloridzin to alpha-glucosidase were 6.1474x10(12), 1.3243X10(5) and 1.076, respectively. The molecular docking result suggested that phloridzin could play the inhibitory role by binding the Lys510 and G1u374 of alpha-glucosidase with hydrogen bonds.
