Antioxidant activity of succinic-oligochitosan rare earth com-plexes
摘要
Abstract
Succinic-oligochitosanrare earth (La (Ⅲ), Nd (Ⅲ),and Eu (Ⅲ))complexes were synthesized and char-acterized. Their antioxidant activities were evaluated by scavenging of superoxide radicals, and hydroxyl radicals and determination of reducing power. The results indicated that all the samples showed obvious antioxidant activity, the order of their scavenging effect on superoxide radicals and reducing power was complex>succinic-oligochitosan> oligochitosan; the order of their scavenging effect on hydroxyl radicals was succinic-oligochitosan>complex> oligochitosan at lower concentration. However, the scavenging effect of succinic-oligochitosan and oligochitosan was weakened sharply, and the scavenging effect of complex was stable at lower concentration. The results may be related to the content and properties of rare earth ion, molecular charge density and the different scavenging mecha-nisms against free radicals.关键词
