The interest of polyphenolics as therapeutic agents against diseases involving radical damage is growing. The phenolic contents of the hulls and flour from the seeds of Fagopyrum esculentum (French variety 'La Harpe') (total phenols, flavonoids, total flavanols, oligomeric proanthocyanidins) are compared with the antioxidative effects of the extracts against reactive oxygen species: hydrogen peroxide, hypochlorous acid, superoxide anion. The higher efficiency of the flour extract can be related to its higher flavanolic content rather than to flavonoids which are predominant in the hull extract.
多酚类物质作为抗自由基损伤相关疾病治疗剂的关注度日益提高。对苦荞麦（法国品种‘拉哈普’）种子的外壳和面粉中的酚类成分（总酚、黄酮类化合物、总黄烷醇、低聚原花青素）进行了比较，并研究了提取物对活性氧（过氧化氢、次氯酸、超氧阴离子）的抗氧化作用。面粉提取物较高的效率可能与其较高的黄烷醇含量有关，而非与外壳提取物中占主导的黄酮类化合物有关。
