荞麦水提物体外抗氧化活性研究

Study of Antioxidant Activity in Vitro of the Water Extract from Buckwheat

为更好开发利用荞麦资源,研究其水浸提液的抗氧化活性。用试剂盒对荞麦水提液进行体外清除·OH、O2-·及DHHP自由基研究,结果表明,荞麦中含有较为丰富的酚类、黄酮等抗氧化成分,它们的总还原能力平均超过2 800 U/m L,对·OH、O2-·及DHHP自由基都有较强的清除作用,但存在明显的品种和产地差别。苦荞水提液清除·OH和O2-·的能力显著高于甜荞。

In order to exploiture of buckwheat resource , a study of antioxidant activity in vitro of water extracts from buckwheat was made. This text used Antioxidant Kit to measure the scavenging activities of water extracts from buckwheat to hydroxyl radical（·OH）, oxygen free radical（O2-·）and DHHP radical. The result expressed there were rich in phenolics and flavonoids. Reducing power of water extracts from buckwheat was more than 2 800 U/mL. The strong scavenging free radical activity was found in extracts. There were significant differences among varieties and habitat.
