摘    要:乌龙茶是我国的特种茶类, 历史悠久, 具有独特的风味和丰富的营养价值及保健功效。抗氧化作用一直是乌龙茶保健功能研究的重要内容, 国内外在这方面也开展了大量研究,并取得了一定成果。近年来, 关于乌龙茶抗氧化能力的物质基础和抗氧化机制也日渐被揭示。乌龙茶茶叶中如茶多酚、茶多糖、茶色素、维生素等有机成分, 以及锌、锰、铜和硒等微量元素都具抗氧化作用, 对羟自由基、超氧阴离子自由基、DPPH自由基均具有一定的清除效果, 并且能有效抑制脂质过氧化, 提高机体抗氧化能力。本文综述了抗氧化检测方法在茶叶中的应用, 以及近年来关于乌龙茶抗氧化活性的研究进展, 并探讨了未来乌龙茶抗氧化研究发展方向以及应用前景。

关 键 词:乌龙茶    抗氧化活性    活性物质    检测方法

Abstract:Oolong tea is one of special type tea in our country with long history. It has a unique flavor, rich in nutritional value and health benefits. Antioxidant effect has been considered as an important part of health function studies on Oolong tea, considerable researches have also been carried out in this respect and achieved certain results at home and abroad. In recent years, the material basis and antioxidant mechanisms for the antioxidant capacity of Oolong tea have also been revealed increasingly. Tea polyphenols, tea polysaccharide, tea pigments, vitamins and other organic ingredients have antioxidant effects in Oolong tea, as well as Zn, Mn, Cu, Se and other trace elements etc. They also have some scavenging effect on ?OH, O2-, DPPH radical, and can effectively inhibit lipid peroxidation, improve the body's antioxidant capacity. This paper reviewed the application of the antioxidant detection methods about tea and the research progress on antioxidant activity of Oolong tea in recent years, and discussed the development direction of future research and prospects on Oolong tea.
Keywords:Oolong tea  antioxidant activities  active ingredients  detection method
