摘要: 自由基是人体过早衰老的主要原因之一,本文利用油菜蜂花粉提取液中的功能成分黄酮类化合物对羟基自由基的清除作用进行了研究,结果表明,油菜蜂花粉中的黄酮类化合物对羟基自由基有着较好的清除效率,在12.5~100μg/ml的范围内浓度与清除效率呈线性关系。

Abstract: Free radical is one of the main reason of ageing. Based on the Fenton mondle of producing hydroxy group free radical,the analyses of on the track by visible absorptiometry have been done .That flavonoids compounds eliminate hydroxy group freeradical has been studied,based on effective constituents extraction of the flowers of Elaeagnus angustifolia L. The result showthat the elimination efficiency is better and the concentration in12.5~100μg/ml is postive related to elimination efficiency.

Key words: pollen, flavonoids, hydroxy group free radical, elimination efficiency
