| 摘 要： | 本文研究了凤凰单枞乌龙茶、绿茶（龙井和碧螺春）以及红茶（滇红和英德红茶）水浸出物的抗氧化特性。结果表明凤凰单枞乌龙茶具有较多的水浸出物，并富含茶多酚、氨基酸、可溶性糖；同时表现出较高的DPPH、超氧阴离了和羟自由基清除能力和抑制油脂过氧化特性，与绿茶水浸出物的抗氧化能力相似，显著高于红茶。这与凤凰单枞乌龙茶的水浸出物中存在较高含量的茶多酚、茶黄素和茶红素，特别是与其中的儿茶素类密切相关。 |

| Abstract: | The antioxidant properties of water extracts of oolong tea (Camellia sinensis, commercial name: Fenghuangdancong),green tea (Longjing and Biluochun) and black tea (Dianhong and Yingdehongcha) were investigated. The oolong tea have high wateryield, concentration of amino acid and soluble sugar. Similar to green tea, oolong tea extracts had a strong antioxidant property(higher radical scavenging activity and lower peroxide value), which was attributed to a high concentration of polyphenols,particularly in catechins and theaflavin. Furthermore, the antioxidant activity of oolong tea was related to catechin concentrations,but not to total polyphenols. |
| Keywords: | oolong tea (commercial name: Fenghuangdancong) antioxidant property catechin |
