摘要
表没食子儿茶素没食子酸酯(Epigallocatechin gallate,EGCG)是绿茶中主要的多酚成分,因其特有的羟基结构具备很强的自由基清除能力、抗辐射和金属螯合作用,在不同领域对EGCG及衍生物有很多研究。本文综述了EGCG的抗辐射作用及对重金属离子的吸附或促排作用研究,探讨EGCG有望成为一种理想的辐射防护剂及重金属吸附剂,甚至促排剂。
Epigallocatechin gallate(EGCG)is a major polyphenol component in green tea.EGCG has high free radical scavenging activity,radiation protection efficiency,and metal-chelating capacity due to its unique structure with hydroxyl groups.EGCG and its derivatives have been reported in various fields.This paper reviews the effects of EGCG,including radiation protection,heavy metal ion adsorption,and promotion of heavy metal ion excretion.EGCG has the potential to be used as an ideal radiation protection agent,heavy metal adsorbent,and even excretion promoting agent.
