Abstract: 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.
