研究了肉桂叶甲醇提取物（CLE）的自由基清除能力和抗氧化活性，并与抗氧化化合物如曲洛酮、丁基羟基茴香醚、没食子酸和抗坏血酸进行了比较。CLE具有清除自由基的活性，特别是对DPPH自由基和ABTS自由基阳离子。它们还表现出还原能力和金属离子螯合活性，沿着羟基自由基清除活性。用亚油酸乳化体系测定CLE的过氧化抑制活性，结果表明CLE具有很好的抗氧化活性。(c)2005爱思唯尔有限公司保留所有权利。
The free radical scavenging capacity and antioxidant activities of the methanolic extract of Cinnamomum verum leaf (CLE) were studied and compared to antioxidant compounds like trolox, butylated hydroxyl anisole, gallic acid and ascorbic acid. The CLE exhibited free radical scavenging activity, especially against DPPH radical and ABTS radical cation. They also exhibited reducing power and metal ion chelating activity, along with hydroxyl radical scavenging activity. The peroxidation inhibiting activity of CLE recorded using the linoleic acid emulsion system, showed very good antioxidant activity. (c) 2005 Elsevier Ltd. All rights reserved.
