近年来，对自由基和抗氧化剂的研究成为热点之一[1]。寻找、筛选具有阻断氧自由基形成或抑制细胞膜过氧化活性的药物越来越受到人们的关注，其中对黄酮类（Flavonoids）化合物的研究也是天然抗氧剂研究中的热门领域。此类天然多酚抗氧化剂具有优良的抗氧化性和清除自由基的能力
In recent years, the study of free radicals and antioxidants has become one of the hot spots [1]. The search and screening of drugs that block the formation of oxygen free radicals or inhibit the activity of cell membrane peroxidation have attracted more and more attention. Among them, the research on flavonoids is also a hot area in the field of natural antioxidants. Such natural polyphenol antioxidants have excellent oxidation resistance and the ability to scavenge free radicals
