Tea () is a beverage beneficial to health and is also a source for extracting bioactive components such as theanine, tea polyphenols (TPP) and tea polysaccharides (TPS). TPS is a group of heteropolysaccharides bound with proteins. There is evidence showing that TPS not only improves immunity but also has various bioactivities, such as antioxidant, antitumor, antihyperglycemia, and anti-inflammation. However, inconsistent results concerning chemical composition and bioactivity of TPS have been published in recent years. The advances in chemical composition and bioactivities of TPS are reviewed in the present paper. The inconsistent and controversial results regarding composition and bioactivities of TPS are also discussed.
茶是一种有益健康的饮品，也是提取诸如茶氨酸、茶多酚（TPP）和茶多糖（TPS）等生物活性成分的来源。TPS是一组与蛋白质结合的杂多糖。有证据表明，TPS不仅能提高免疫力，还具有多种生物活性，如抗氧化、抗肿瘤、降血糖和抗炎作用。然而，近年来关于TPS的化学成分和生物活性的研究结果并不一致。本文综述了TPS化学成分和生物活性的研究进展。同时也讨论了关于TPS组成和生物活性的不一致和有争议的结果。
