摘要: 分别用DPPH•分光光度法及TBARS法研究了BHT、TBHQ、TP与VE的抗氧化活性。结果显示它们对DPPH•皆有清除作用,清除活性为TBHQ>TP>VE>BHT;对亚油酸的脂质过氧化也都有抑制作用,抑制活性为BHT>VE>TBHQ>TP。不同测试体系中它们表现出的抗氧化活性不同,值得注意。

Abstract: A study of the antioxidant activities of four antioxidants was carried out by DPPH•method and TBARS method. The results showed the tested antioxidants all could screen the DPPH•and inhibit the lipid pro-oxidation of linoleic acid effectively. The orders of their antioxidant activities were TBHQ>TP>VE>BHT and BHT>VE>TBHQ>TP by DPPH•method and TBARS method respectively. It was worth notice that the different antioxidant activities were associated with the different assays.
