覆盆子黄酮抗氧化活性研究

Study on the Antioxidant Activity of Raspberry Flavones

经分离提取后,对覆盆子黄酮提取物的体外抗氧化活性进行了研究,结果表明,覆盆子黄酮提取物对OH、H2O2、DPPH均有不同程度的清除作用,清除率强弱顺序为:纯化后的覆盆子黄酮>覆盆子黄酮二次萃取物>覆盆子黄酮粗提物;覆盆子黄酮提取物对花生油的自动氧化也有明显的抑制作用,0.2%覆盆子黄酮提取物在油脂中的添加量好于0.02%的BHT。

The anti-oxidation study for Raspberry flavones had shown that Raspberry flavones could clear up OH, H202 and DPPH in vitro. The strength of order of clearance as follow： the flavones after purifying 〉 the flavones after second extraction 〉 the flavones after crude extract. The flavones after purifying could obviously hold back oxidation of peanut oil. The anti-oxidation effect of 0.2% flavones in peanut was better than 0.02% BHT.
