摘要：本文主要以中低档绿茶为原料简单工研究了茶叶中的有效成分茶多酚、咖啡碱、茶多糖的复合提取技术以及超声波对绿茶中所含茶多酚等物质浸出的特性影响。建立了从同一茶叶原料中同时获得茶多酚、咖啡碱、茶多糖3种产品的工艺流程，从而充分利用茶叶资源，避免了单一成分分离而导致其他成分浪费的现象，具有重要的科研价值和经济价值。并通过仪器分别测定了他们各自在茶叶中所占的百分含量。研究表明它们具有抗氧化，抗癌，增强机体免疫力等功效，其百分含量分别占茶叶干质量的18%~36%，2%~5%，和0.5%~2%。
关键词： 茶，茶多酚，咖啡碱，茶多糖。

Abstract: This article Zhongdi Dang green tea as raw material to work on a simple tea in the tea polyphenols active ingredients, caffeine, tea polysaccharide from the compound of ultrasound technology, and green tea contained in the tea polyphenols and other properties of the material leaching. The establishment of the raw materials from the same tea in the tea polyphenols were at the same time, caffeine, tea polysaccharide three kinds of products the process, make full use of tea resources and avoid the result of a single component from other components of the waste is of important scientific research value and Economic value. And equipment were determined through their respective share of tea in the content. Research shows that they are anti-oxidation, anti-cancer, enhance immunity, such as effectiveness, the percentage of its stem quality tea accounted for 18% to 36%, 2% to 5% and 0.5% to 2%.
Key words: tea, tea polyphenols, caffeine, tea polysaccharide.
