目的：核桃叶提取物均具有较强的抗氧化性,但它的有效成分含量随采摘的时间不同而出现动态变化,通过比较几个月份采摘核桃叶提取物的抗氧化性,分析采摘时间与抗氧化性的关系。方法：不同月份采收的核桃叶提取物按相同剂量加入到食用植物油中,通过用可见光分光光度法测定吸光度值,与标样吸光值比较定量,来测得食用植物油的过氧化值,不同月份提取物之间相互比较,并同加入的等量BHT/BHA、空白两组进行比较,保存期间每隔一段时间观察一次。结果：9月份丙酮提取物的抗氧化作用最好,好过相同浓度BHT。结论：核桃叶抗氧化性随采摘时间呈动态变化,于9月份采摘的核桃叶抗氧化性最好。

Objective:The extract of walnut leaves show strong antioxidant activities, but the quantities of active components are different according to different growth stages. The time of picking walnuts leaf depends on comparison of oxidation resistance of walnuts leaf extract picked from different months. Methods: The same doses of walnut leaf extract harvested in different months were added into edible vegetable oil. Extracts from different months were compared with each other. All of these extracts were divided into three groups, with equal BHT, BHA and blank in them. And then they were observed after some time. Results: Among them, the antioxidant activities of acetone extract in September. had the highest antioxidant activity, and better than BHT, Conclusion: The antioxidation effects of Walnut leaves are different in different periods, and the best one is in September.
