簡單介紹了茶葉中茶多酚和咖啡因的藥理活性以及茶葉有效成分的組成和幾種主要兒茶素類化合物的結(jié)構(gòu)，分析探討了提取分離廢棄茶葉的原因和意義，并綜述了近年來國內(nèi)外有關(guān)茶葉中茶多酚提取分離技術(shù)的研究進展，包括溶劑提取法、離子沉淀法、超聲波提取法、超臨界流體萃取法、微波輔助萃取法、柱色譜法、大孔吸附樹脂法和高速逆流色譜法，通過不同的實驗過程對不同技術(shù)手段的應(yīng)用及特點進行概述，并對這一研究領(lǐng)域的發(fā)展前景和發(fā)展方向做出展望。

This paper introduces pharmacological activities of tea polyphenols and caffeine in tea leaves, effective ingredients of tea composition, and structures of several main catechines compounds, and discusses the cause and significance for extraction and separation of the waste tea. The research progress of relevant extraction and separation techniques of tea polyphenols was reviewed, including solvent extraction, ion precipitation, ultrasonic extraction, supercritical fluid extraction, microwave-assisted extraction, column chromatography, macroporous adsorption resin, and high speed counter current chromatography. The application and features of different techniques were summarized through diverse experiment process, so as to look to the development prospect and development direction of this research in the field.
