坚果类食物清除R00的作用

采用一种测定样品清除氧自由基能力的方法，检测一些坚果类食物清除ＲＯＯ·的作用，结果表明葵花子具有较强的清除ＲＯＯ·的作用．花生、核桃等次之，栗子、莲子的作用最弱；另外，不同的坚果类食物清除ＲＯＯ的作用在水溶相与脂溶相分布也有所不同；相关分析表明坚果类食物脂溶相清除ＲＯＯ·的能力与其脂肪含量有显著相关关系，水溶相清除ＲＯＯ·的作用来源尚有待进一步研究。

Oxygen-radical absorbance capacity assay was used to measure the antioxidant capacity of nuts. The results showed that the sunflower seeds had the strongest action against ROO and followed by peanuts and walnuts. Lotus seeds and chestnuts were the weakest among all nuts tested. The antioxidant capacity was distributed differently between water and lipid soluble phases among different nuts. The antioxdant capacity from lipid soluble phase was correlated positively with the fat content of nuts. However the origin of antioxidant capacity from water soluble phase remained to bo further investi- gated.
