Abstract:
Objective To investigate the inhibition of Eriobotryae Folium from twenty different districts towards phosphodiesterase 4(PDF4) in vitro.Methods The Eriobotryae Folium were extracted with 95％ ethanol reflux and the inhibition rates against PDE4D2 were carried out by liquid scintillation counting method.Results All the samples exhibited inhibitory activities towards PDE4 at 5 mg/L.Among them,nine samples were of the inhibition rate less than 80％,eleven samples were of more than 80％ inhibition and eight samples were of more than 90％ inhibition.Conclusion The Eriobotryae Folium shows significantly different inhibitory activities towards PED4.
