摘要
通过改良邻苯三酚自氧化法(简称325nm法)测定芝麻酚清除自由基能力。试验表明:在等质量浓度条件下,芝麻酚对超氧阴离子自由基(O2-·)的清除效率高于BHT及VE,当芝麻酚的质量浓度为0.8g/L时,对O2-·自由基的清除率达到80.68%,高于BHT的77.12%及VE的55.65%。因此,芝麻酚具有较强的清除O2-·自由基的能力。
The activity of sesamol scavenging superoxide anion radical (O2^-·) was determined by the modified method of pyrogallol auto-oxidation. The results indicated that the effect of sesamol on scavenging O2^-· radical was better than that of BHT and VE. It was 80.68 % at concentration of 0.8 g/L comparing with 77.12 % of BHT and 55.65 % of VE.
