| 摘 要： | 对肉桂精油(CEO)的抗氧化和清除游离基活性的比较是基于总体抗氧化能力、清除超氧阴离子自由基能力、清除羟基自由基能力、抗亚油酸脂质过氧化能力、清除DPPH自由基5个方面,并与其他的合成抗氧化剂如BHT、PG做比较。实验结果表明,在一定浓度范围内,CEO的羟自由基清除能力强于BHT和PG;清除超氧阴离子自由基的能力强于PG;清除DPPH自由基能力、抗氧化活性比BHT和PG弱;CEO抑制亚油酸的过氧化能力比BHT和PG略弱。实验表明了CEO在某些方面具有良好的抗氧化效果。

| Abstract: | The antioxidant activities and free radical scavenging of cinnamon(Cinnamomum cassia Presl) essential oil(CEO) were evaluated based on total antioxidant ability, superoxide anion and hydroxyl radical scavenging activities, inhibition of lipid peroxidation in linoleic acid, and scavenging DPPH radical. The various antioxidant activities were compared with synthetic antioxidants such as butylated hydroxytoluene(BHT) and propyl gallate(PG). The results revealed that the hydroxyl radical scavenging were higher ... |
