摘要

氧化应激可诱发多种疾病的发生。植物次生代谢物可能通过中和自由基和刺激内源性抗氧化机制发挥抗氧化剂的作用。多酚是具有抗氧化活性的重要次生代谢产物之一。它们可以通过不同的机制发挥作用,这取决于它们的结构。多酚类物质广泛存在于中草药中,常用的有野越橘(Aroniae fructus)和越橘(Myrtilli fructus),均含有丰富的花青素和单宁,具有较高的抗氧化活性。姜黄根茎(Curcumae rhizome)中的主要化合物是姜黄素,具有抗氧化和抗炎活性。此外,茶叶(Camelliae sinensis folium)和咖啡豆(coffae semen)在日常生活中高度存在,它们显著地促进了每日抗氧化剂的摄入,并为机体免受氧化应激的影响提供了必要的保护。

Antioxidant activity of plant secondary metabolites
Oxidative stress can induce the development of many different disorders. Plant secondary metabolites may act as antioxidants by neutralisation of free radicals and by stimulation of endogenous antioxidant mechanisms. One of the important secondary plant metabolites with antioxidant activity are polyphenols. They can exert activity through different mechanisms depending on their structure. Polyphenols are widely present in herbal drugs, and some of the commonly used ones are aronia berry (Aroniae fructus) and bilberry fruit (Myrtilli fructus), both rich in anthocyanins and tannins and with high antioxidant activity. The main compounds in turmeric rhizome (Curcumae rhizome) are curcuminoides that manifest antioxidant and anti-inflammatory activity. Furthermore, tea leaf (Camelliae sinensis folium) and coffee bean (Coffeae semen), highly present in everyday life, significantly contribute to the daily intake of antioxidants and provide necessary protection of the organism from the consequences of oxidative stress.
