摘　　要：以大豆色拉油和精炼菜籽色拉油为实验油 ,采用活性氧法 (AOM)研究了儿茶素EGCG的长链脂肪酸酯EGCG单棕榈酸酯的抗氧化活性 ,并与合成抗氧化剂特丁基 - 4-羟基茴香醚 (BHA)、2 ,6 -二特丁基对甲酚 (BHT)、叔丁基对苯二酚 (TBHQ)的抗氧化活性进行了比较 ,结果表明脂溶性的EGCG单棕榈酸酯的抗氧活性与TBHQ相当 ,而比BHA、BHT有更强的活性 ,是食用植物油很好的抗氧化剂。The antioxidative activity of the lipid-soluble EGCG palmitate in salad oils was evaluated and compared with that of synthetic antioxidants such as TBHQ,BHA and BHT by AOM text.The results demonstrated that the antioxidative activity of the single-substitution EGCG palmitate was almost corresponding to that of TBHQ,and more effective than that of BHA and BHT.
