    沙田柚果皮精油、中果皮和果核提取物的抗氧化活性研究

    Study on Antioxidant Activity of Essential Oil from Flavelo and Extracts of Mesocarp and Seed of Shatian Shaddock

      摘要
    • 摘要: 用硫氰酸铁法测定了油田柚外果皮精油、中果皮和果核提取物在亚油酸体系中的抗氧化活性，发现沙田柚中果皮的乙醚提取物和果核的乙酸乙酯提取物对亚油酸的过氧化抑制率高达99．17％和92．55％，它们的抗氧化活性前者高于丁基羟基茴香醚（BHA）而后者与BHA相当；果皮精油对亚油酸的过氧化抑制率为55．24％；研究证明中果皮乙醚提取物和果核乙酸乙酯提取物的抗氧化活性与所含的酚类物质有关。

       

      Abstract: The antioxidant activity of essential oil from flavelo and extracts from mesocarp and seed of Shatian shaddock in linoleic acid system was investigated by ferric thiocyanate method. The results showed that the inhibition of linoleic acid peroxidation of diethyl ether extract from mesocarp (DEEM) and ethyl acetate extract from seed (EAES) was w = 99.17 % and 92.55% respectively. The antioxidant activity of DEEM was higher than that of BHA and EAES was as high as BHA. The inhibition of linoleic acid peroxidation of essential oil was w =55.24%. The study results proved that antioxidant activity of DEEM and EAES was correlated with total phenolic compounds contained in them.
