洋葱 黄酮类化合物 抗氧化活性
2009/9/11
通过测定洋葱中黄酮类化合物对Fe2+的螯合能力,对DPPH自由基、亚硝酸盐的清除能力,对卵黄脂蛋白脂质过氧化及油脂过氧化的抑制作用,研究了其体外抗氧化活性。结果表明:洋葱中黄酮类化合物对Fe2+具有很强的螯合能力,对DPPH自由基、亚硝酸盐具有良好的清除能力,对卵黄脂蛋白脂质过氧化及油脂过氧化具有明显的抑制作用,即洋葱中黄酮类化合物具有良好的体外抗氧化活性。
酶法提高大豆糖蜜抗氧化活性及其机理(Enhanced Antioxidant Activity of Soybean Molasses Using Cellulase)
大豆糖蜜 抗氧化活性 生物酶解
2009/5/22
为提高大豆糖蜜的抗氧化活性,将大豆糖蜜溶液与纤维素酶溶解于pH值5.0的50mmol/L Tris-HCl 缓冲液中,于50℃保温30min。对比了酶解前后大豆糖蜜的清除DPPH自由基能力和还原力,并分析了异黄酮的组成差异。结果表明:达到50% DPPH自由基清除率,需未处理样品17.15g/L,而处理样品仅为9.19g/L。在相同的质量浓度下,处理后的大豆糖蜜还原力要高于未被处理的大豆糖蜜。纤维...
