Variation pattern in the composition of essential oil, hydrodistilled from the over‐matured ower heads of Echinacea purpurea (L.) Moench under subtropical climate was characterized by GC–MS and GC analysis. The plants ower from June till December and climatic factors such as temperature and humidity were found to affect both the content and the composition of the essential oil.
