摘　　要：目的:考察不同时间采集的胡桃楸叶和果实中胡桃醌含量的动态变化规律,为胡桃楸资源的合理开发利用提供理论基础。方法:采用高效液相色谱法测定胡桃楸叶和果实中胡桃醌的含量。结果:胡桃楸果实中胡桃醌的平均含量较高(1.93 mg.g-1),而叶中胡桃醌的平均含量较低(0.30 mg.g-1)。胡桃楸叶中胡桃醌的含量随着叶的生长而不断增高,随着叶的枯萎转而下降。胡桃楸果实中胡桃醌的含量在果实未成熟时最高,果实近成熟后其中胡桃醌的含量急剧下降。结论:胡桃楸未成熟的果实中胡桃醌的含量最高。Objective： For reasonable development and utilization of the resource of Juglans mandshurica,the dynamic variation of juglone content in the leaves and fruits collected in different months was investigated.Method： Juglone content in the leaves and fruits of Juglans mandshurica was determined by HPLC.Result： Juglone content in the fruits（1.93 mg·g-1） was more than that in the leaves（0.30 mg·g-1）.Juglone content in the leaves increased with the growth of leaves,and decreased with the withered of leaves.Comparing with the immature fruits,juglone content in the ripe fruits decreased obviously.Conclusion： Juglone content in the immature fruits was the highest.
