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。

[Abstract]
The anti-oxidation study for Raspberry flavones had shown that Raspberry flavones could clear up OH-, H2O2 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.
