Catechin is a plant polyphenol with valuable antioxidant and health-promoting properties. Polymerization is one way to stabilize flavonoids and may cause changes in their specific properties. The aim of this study is to obtain a polymeric complex catechin compound with high thermal stability. As a result of polymerization, a condensed and cross-linked catechin structure was obtained, which guaranteed high thermal resistance and, moreover, the phosphorus groups added in the second step of polymerization ensured that the compound obtained had thermal stability higher than natural condensed tannins. The first step of self-polymerization of (+)-catechin may be an easy way to obtain proanthocyanidins with greater antioxidant activity. The second step of the polymerization obtained a polymeric complex catechin compound that showed better thermal stability than catechin. This compound can potentially be used as a new pro-ecological thermal stabilizer.
儿茶素是一种具有宝贵抗氧化和促进健康性质的植物多酚。聚合是稳定类黄酮的一种方法，可能会导致其特定性质发生变化。本研究的目的是获得具有高热稳定性的聚合型儿茶素复合物。通过聚合反应，得到了一种缩合交联的儿茶素结构，保证了高耐热性，而且在第二步聚合中添加的磷基团确保了所得到的化合物具有高于天然缩合单宁的热稳定性。(+)-儿茶素的自聚合第一步可能是获得具有更大抗氧化活性的原花青素的一种简单方法。第二步聚合得到的聚合型儿茶素复合物比儿茶素具有更好的热稳定性。这种化合物有可能被用作一种新型的生态友好型热稳定剂。
