| 摘 要： | 以VC 为阳性对照，对杜仲素和高纯绿原酸清除羟自由基(·OH)、超氧阴离子自由基(O2·)及1,1- 二苯基-2- 苦苯肼自由基(DPPH 自由基)活性进行研究，并通过计算清除率比较清除各种自由基活性的效果。结果表明：杜仲素在不同自由基体系中抗氧化活性不同，清除自由基能力为O2·＞ DPPH 自由基>·OH，对3 种自由基的最大清除率依次为95.85%、75.31% 和31.10%。因此，杜仲素具有较强的抗氧化作用。

| Abstract: | To provide theoretical evidences for developing novel natural antioxidants, eucommin and high-purity chlorogenic acid were assessed for their antioxidant effects by hydroxyl, superoxide anion and DPPH free radical assays with vitamin C as a positive control. Curves of free radical scavenging ratio versus concentration were plotted for each of these three compounds. As a result, eucommin had different scavenging effects against different radicals and the best ability to scavenge superoxide anion radicals, followed by DPPH and hydroxyl radicals, with corresponding maximum scavenging ratios of 95.85%, 75.31% and 31.10%. Therefore, eucommin is a potential strong antioxidant. |
