摘要
为评价滁菊水提液抗氧化活性,采用还原力、清除羟基自由基及DPPH能力、抑制卵黄脂质过氧化能力等方法,以Vc为对照进行研究。结果表明:滁菊水提液能有效的清除羟基自由基及DPPH,具有较强的还原能力,可以很好抑制卵黄脂质过氧化;在一定浓度范围内其抗氧化能力随浓度的增加而增强。因此,可以将滁菊水提液开发为抗氧化健康饮品。
To evaluated antioxidative activity of aqueous extract of Chuju Chrysanthemum morifolium,Compared with Vc,the antioxidantive activity of aqueous extract of Chuju Chrysanthemum morifolium.was studied by measuring its reducing power,scavenging effects on hydroxyl radical（·OH）and·DPPH radical,activity of decreasing the lipid peroxidation of yolk.The results showed that aqueous extract of Chuju Chrysanthemum morifolium not only had a strong scavenging capacity on ·OH and DPPH radical,but also has strong reducing power and significant inhibition effects on the lipid peroxidation of yolk.the antioxidantive activity of aqueous extract of Chuju Chrysanthemum morifolium was improved with the higher concentration.Thus,Chuju Chrysanthemum morifolium is promising to be a natural antioxidative health drink.
