目的:研究引种紫锥菊中有效成分的动态积累规律。方法:分别采用HPLC和比色法测定紫锥菊生长过程中不同部位菊苣酸和总多酚含量。结果:一年生紫锥菊中总多酚含量变化不大，不同时期不同部位的菊苣酸含量存在差异，各部位菊苣酸含量在盛花期达最大值。结论:紫锥菊采收期取决于菊苣酸含量。研究结果可为山东引种紫锥菊提供理论依据。

This study was aimed to analyze the dynamic accumulation of active ingredients of Echinacea purpurea. Contents of cichoric acid and total polyphenols in different parts through the whole growth process were determined by HPLC and colorimetry. The results showed that the content of total polyphenol changed little in annual plant. There were differences in content of cichoric acid of different parts in different periods. And the content reached the maximum at flowering stage. It was concluded that the harvest stage depended on the content of cichoric acid. The results provided theoretical basis for induced plant in Shandong province.
