本研究用ABTS（2,2-联氮-二(3-乙基-苯并噻唑-6-磺酸)二铵盐）自由基清除实验和铜离子还原法测定玫瑰香蒸馏酒的总抗氧化能力，实验结果以Trolox（可溶性维生素E）等价表示。结果表明，添加了玫瑰花发酵的蒸馏酒样的总酚含量、自由基清除作用、铜离子还原作用均比未添加玫瑰花的对照组酒样明显提高。并且随着玫瑰花使用量的增加，酒样总酚含量、对自由基的清除作用和对铜离子的还原作用也相应增加。总酚含量与总抗氧化能力呈同时上升趋势，说明玫瑰香蒸馏酒的总抗氧化能力与多酚类物质含量有较密切关系。

In this study, we investigated the antioxidant capacity of rose petal liquor through the methods of ABTS (2,2'-Azinobis-(3-ethylbenz-thiazoline-6-sulphonate))free radical scavenging and CUPRAC (copper reducing antioxidant capacity). The experimental results were indicated by Trolox (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid) equivalent antioxidant capacity. The results showed that, total phenolic content of rose petal liquor, the scavenging effects on free radicals, and copper ion reduction were higher than those of non-rose petal liquor. As the use level of rose petal increased, total phenolic content, scavenging effects on free radical, and copper ion reduction were also increased accordingly. And total phenolic content was proportional to total antioxidant capacity, which suggested that there was a close relationship be-tween total antioxidant capacity and polyphenol content of rose petal liquor.
