Objective To study dynamic change of the main chemical components from the fruit of Comus officinalis. Methods The main chemical components were determined derived from different growth year and different growth stages in order to approach the accumulation trend of the fruit of Comus officinalis. Results The chemical components were different with great fluctuation for different tree ages. So every 20～30 year as one cycle of growth, it was supreme that the growth period in 20～30 year, 50～70 year or over 100 year. Conclusion The main chemical components was higher at bearing peak period for 20～30 year, 50～70 year or over 100 year growth of Comus officinalis. The optimum harvest time was the stage which the color of fruit of turned red after frost's descent.%目的 研究山茱萸干燥果肉中主要化学成分的动态变化.方法 通过对不同树龄和不同时期的山茱萸进行取样,并测定干燥果肉中主要化学成分的含量,研究干燥果肉中主要化学成分的积累规律.结果 不同树龄阶段其主要化学成分的含量不同,含量高低交替出现,每20～30年为一个周期,以20～30年,50～70年,100年以上的最高;不同时期山茱萸主要化学成分的波动较大,并且与鲜果的外观色泽有明显的相关性,以鲜果及果肉完全着色(即色泽不再变化)时采收(也即霜降以后采收)含量最高.结论 树龄为20～30年,50～70年,100年以上的,处于结果盛期,干燥果肉中主要化学成分含量较高.山茱萸在霜降以后,即山茱萸果皮、果肉变为红色时采收最佳.
