摘要

合成了含有氨基、硫和氧基的新型蒽醌类环抗氧化剂，并采用铈还原抗氧化能力(CERAC)法测定了其抗氧化能力。采用1H, 13C NMR, FTIR-spectroscopy和ESI (Electrospray Ionization)质谱法对具有CERAC抗氧化能力的蒽醌衍生物进行了表征。本研究首次用CERAC方法分析了蒽醌类化合物的抗氧化能力，结果表明CERAC-Trolox等效抗氧化能力(TEAC)值高于Trolox。需要指出的是，所有合成的蒽醌衍生物由于其含硫和含氮的特性，在生物学特性方面都有潜在的应用潜力，因此它们将对文献做出重要贡献。

Synthesis and Determination of Cerium(IV)-Reducing Antioxidant Capacity (CERAC) Assay of Some New Anthraquinones

Novel anthraquinone-based cyclic antioxidants containing amino, thio and oxo groups were synthesized and their antioxidant capacity was determined by using the cerium(IV)-reducing antioxidant capacity (CERAC) assay. 1H, 13C NMR, FTIR-spectroscopy and ESI (Electrospray Ionization) mass spectrometry were used for the characterization of anthraquinone derivatives exhibiting CERAC antioxidant capacity. This study is of great importance, because the antioxidant capacity of anthraquinone compounds was analyzed for the first time by the CERAC method and CERAC-Trolox equivalent antioxidant capacity (TEAC) values were higher than that for Trolox. It should also be noted that, since all synthesized anthraquinone derivatives have the potential to find applications in terms of their biological properties due to their sulfur and nitrogen content, they will make an important contribution to the literature.
