- W2379409856 abstract "The in vitro radical scavenging and antioxidant capacity of selenium nanoparticle(nanoSe0)-amino acid sols,such as nanoSe0-Glu,nanoSe0-Gly and nanoSe0-Ala were evaluated by using different in vitro analytical methods.The experimental results demonstrated that the hydroxyl radical(OH-·) scavenging capacity of nanoSe0-amino acid sols increased with the concentration increasing.NanoSe0-amino acid sols also had an effective superoxide anion free radical(O-2·) scavenging capacity which were positively related with the con-centration of nanoSe0-amino acid sols and nanoSe0.The IC50 values of nanoSe0-amino acid sols were(57.5±7.5) μmol/L(nanoSe0-Glu),(6.78±0.23) μmol/L(nanoSe0-Gly),(32.3±6.9) μmol/L(nanoSe0-Ala),respectively.NanoSe0-amino acid sols scavenged 1,1-2diphenyl-2-pierylhydrazyl free radical(DPPH·) effectively.The IC50 values of nanoSe0-amino acid sols were(15.5±0.27) μmol/L(nanoSe0-Glu),(15.3±0.89) μmol/L(nanoSe0-Gly),(15.2±0.60)μmol/L(nanoSe0-Ala),respectively.In addition,the results of the oxygen radical absorbance capacity(ORAC) showed that the area under curve(AUC) of the nanoSe0-amino acid sol was linearly related to its concentration and the antioxidant capacity of nanoSe0-Ala sol was higher than those of nanoSe0-Gly sol and nanoSe0-Glu sol.As a conclusion,nanoSe0-amino acid sols could scavenge O2-·,OH-·,DPPH· efficiently,it could be used as natural antioxidant component and food preservative agents or nutraceuticals." @default.
