Abstract

Cichoric acid and caftaric acid are the main phenolic compounds in Echinacea purpurea tops The level of these phenolic compounds in E purpurea extracts is affected by different factors such as seasonal variations drying methods extraction methods and growing location of the plant HPLC analysis of caffeic acid derivatives in extracts of Echinacea purpurea Cultivar aerial parts produced by boiling water extraction and ethanolwater extraction methods showed various levels of the derivatives Our findings revealed that the Iranian cultivated E purpurea had a high level of cichoric acid 35–57 Caftaric acid was also the main phenolic compound in E purpurea tops 31–45 After 2 h of boiling water extraction the level of cichoric acid was 57 whereas the level of this acid in 6040 ethanolwater extraction did not exceed 39
