| 摘 要： | 茶多糖降血糖功效尤为突出，其防治糖尿病作用效果备受关注。茶多糖系茶叶中具有生物活性的复合多糖的简称，由糖类、蛋白质、果胶和灰分等物质组成。茶多糖的结构研究是近年来研究的热点，主要涉及茶多糖单糖组成、分子量、糖苷键类型、连接方式及其在溶液中的构象变化。相应的生物学活性以降血糖功效最为突出，究其作用机制与抗氧化作用和糖代谢酶调控相关。本文综述和分析了茶多糖的组成结构及其降血糖研究，以期为进一步研究提供参考依据。

| Abstract: | Tea polysaccharides have been reported in their excellent effects for decreasing blood sugar,especially in prevention for diabetes.The tea polysaccharide is defined for conjugated polysaccharides comprised of various monosaccharide,proteins,pectin and ashes.In recent years,studying for component profile of tea polysaccharides has become a favorite topic including monosaccharide composition,molecular weight,glucosidic bond,conjugated method and conformation changes.Among the bioactivities,the most prominent effect of tea polysaccharides is decreasing blood sugar that is correlation to its function in antioxidant and regulating metabolic enzymes for sugar. This paper reviewed literatures for tea polysaccharides in composition,structure and effect on decreasing blood sugar for further studies. |
