【Abstract】 Water-soluble polyhydroxylated fullerene derivatives(fullerenol) were synthesized,and their scavenging ability for OH-radical was studied by the combination of ESR spectroscopy and spin-trapping technique with phenyl-t-butyl-nitrone. It was found that fullerenols showed an excellent efficiency in eliminating OH free radicals generated by UV photolysis of H2O2.At an applied fullerenol concentration of 0.3mg/mL in the final solution,a radical scavenging efficiency of approximate 95%was achieved, revealing the potential use of these compounds as novel potent free radical scavengers in biological systems.更多还原
