摘要
研究了以碎茶为原料获得了在一次工艺中制取茶叶抗氧剂、咖啡碱、叶绿素的最佳工艺条件，并对茶多酚的纯度与抗氧性的关系，柠檬酸对茶多酚的抗氧增效作用进行了研究，指出茶多酚作为抗氧剂产品必须具有较高的纯度。
The optimal technique for extraction of antioxidant,catfeine,chlorophyll from tea leafs were researched.The relationship between tea polyphenol purity and antioxy-genic activity and the synergistic effect of citric acid on tea polyphenol’s antioxygenic activity were also researched.It was showed clearly that tea polyphenol must be in high purityif to be used as antioxidant.
