摘要
以70%乙醇为溶剂提取黄瓜黄酮类化合物,并对其黄酮含量进行测定;采用水杨酸比色法测定黄瓜中黄酮类化合物对羟基自由基的清除效果。结果表明:黄瓜中含有黄酮类化合物;且黄瓜中黄酮类化合物对羟基自由基有明显的清除效果,清除率达63.95%。
In this paper,the hydroxyl radical e1iminating activities of flavonoid extracted from Cucumis sativus Linn.,by 70 % alcohol was studied.The salicylic acid method were used to determine the effect of removing free radicals of·OH by flavonoids in the Cucumis sativus Linn..The results show that the flavonoids can significantly remove free raclicals of·OH.The eliminaing ratio of free raclicals o（f·OH）is 63.95 %.
