Tea polysaccharide (TPS),which is considered to be another important active ingredient after Tea Polyphenols Relay, consists of monosaccharides which have a variety of biological activity and the complex structure. It has hypoglycemic, lipid-lowering, anti-thrombosis, anti-oxidation, anti-aging, anti-atherosclerotic, anti-cancer and improve immune function. Modern medical research shows that aging, inflammation, cardiovascular disease, cancer are closely related to the increasing of reactive oxygen species. A large number of natural products in the antioxidant components can clear free radicals, impede the lipid peroxidation by which it was induced, play a preventive role in the occurrence of these diseases. So we review the related literature of TPS in the anti-aging of antioxidants, and aim to provide more reference for the future TPS medicinal research.%茶叶中的茶多糖(TPS),被认为是茶叶中继茶多酚之后又一重要活性成分.TPS由具有多种生物活性、结构复杂的单糖构成,具有降糖、降脂、抗血栓、抗氧化、抗衰老、抗动脉粥样硬化、抗癌及改善机体免疫功能等作用.现代医学研究证明,衰老、炎症、心血管病、癌症的发生与活性氧自由基的增多密切相关,而大量天然产物中的抗氧化成分能够清除自由基,阻断由它们引发的脂质过氧化,起到预防上述疾病发生的作用.本文就TPS在抗氧化延缓衰老方面的相关文献进行综述,旨在为未来TPS的药用研究提供更多参考.
