摘　　要：目的对杜仲不同部位主要有效成分的含量进行动态研究,确定杜仲最佳采收期。方法采用高效液相色谱法,以杜仲主要有效成分绿原酸、松脂醇二葡萄糖苷含量为评价指标,研究杜仲皮、叶、枝采收期。结果不同采收期杜仲不同部位各成分有明显差异。结论杜仲皮于5月份、6月份采收最佳;杜仲叶于4月份采摘最佳;杜仲枝的松脂醇二葡萄糖苷含量很低,从绿原酸含量方面考虑,8月份采收最佳。Objective To research the dynamic change of the content of main effective ingredients in different part of Eucommiae ulmoides in order to determine the optimal collection period. Methods HPLC was used. The contents of the main effective ingredients chlorogenic acid and pinoresinol diglucoside in Eucommiae ulmoides were as evaluating indicators. The collection period of bark, leaves and branches of Eucommiae ulmoides was studied. Results The contents of various ingredients in different parts of Eueommiae ulmoides were obviously different. Conclusion It is the optimal collection time to get the bark of Eucommiae ulmoides in May or June. For the leaves, it is April. The content of pinoresinol diglucoside in the branches of Eucommiae ulmoides is very low.Considering the content of chlorogenic acid, August is the best.
