米糠中γ-谷维醇抗脂质氧化作用

The Antioxidant Effects of γ-Oryzanol in Rice Bran on Liposome Oxidation

利用脂质体体外氧化试验 ,对γ -谷维醇及其水解物的抗氧化性进行了研究。通过实验 ,测定了γ -谷维醇的最低有效抗氧化浓度。对其水解产物的抗氧化研究表明 ,其组成结构中 ,阿魏酸是起抗氧化作用的主要基团 。

The antioxidant effects of γ-oryzanol in rice bran was investigated by liposome oxidation test in vitro. And its effective concentration of antioxidation was determined. In addtion, the antioxidant activity of its hydrolysate was studied. The results indicated that the ferulic acid was the main antioxidant part in the molecule of γ-oryzanol.
