摘　　要：茶多糖是一类相对分子质量较大的,具有一定活性的水溶性复合杂多糖。根据对茶多糖的紫外、红外及气相色谱的分析,茶多糖由糖类、果胶及蛋白质等物质组成。为了更清晰地了解茶多糖的研究现状并对茶多糖进一步开发和研究,主要对近年来茶多糖的提取方法、分离纯化和分子组成等方面进行了综述,并对研究中存在的问题进行了分析,对其开发前景进行了展望。Tea polysaceharide is a kind of larger molecular weight and an active water-soluble compound polysaccharide. According to the anal- ysis of Ultraviolet （UV） ,hdrared（IR） and Gas Chromatography （GC）, tea polysaecharide is composed of sugar, pectin and proteins and other substances. In order to more clearly understand the situation of tea polysaccharide and the further development and research, the extraction, sep- aration and purification and molecular composition and other aspects of tea polysaecharide were reviewed, and the problems existing in the re- search were analyzed, the development prospect was forecasted.
