摘要:

以从新疆天山八一林场采集的中国树花(Ramalina sinesis Jatta.)为材料,用乙酸乙酯为溶剂回流提取松萝酸,用高效液相色谱法测定松萝酸的含量并对松萝酸的还原力、羟自由基清除率进行测定。结果表明:中国树花中松萝酸的总含量为18.32%,松萝酸具有较强的还原力及清除羟自由基的能力。

关键词: 中国树花, 松萝酸, 高效液相色谱, 抗氧化

Abstract:

In this study, usnic acid in Ramalina sinesis Jatta growing in August First forest farm, Tianshan mountain area, Xinjiang autonomous region was extracted with ethyl acetate by reflux extraction for content determination by HPLC and antioxidant activity evaluation by reducing power and hydroxyl free radical scavenging assays. The content of usnic acid in Ramalina sinesis Jatta was 18.32%, and usnic acid derived from Ramalina sinesis Jatta had interesting reducing power and hydroxyl free radical scavenging capacity (with vitamin C as the control).

Key words: Ramalina sinensis Jatta, usnic acid, HPLC, antioxidant activity
