. Little impact on HSA protein conformation was observed during their combination and the hydrogen bond and van der Waals force were the main forces for(

R
)-(-)-mellein and HSA. Molecular docking result explored that(

)-(-)-mellein molecule was located in the hydrophobic cavity of protein subdomain ⅢA(site Ⅱ ) and there were four broad hydrogen bonds in the complex molecule which corresponded to amino acid residues Arg-485,Leu-481,Arg-348 and Arg-348. These results of antioxidation activity and effect on HSA protein conformation could provide the experiment and the theory basis for the evaluation of the medicinal prospects of(
