We understood that alkylamides were important for the efficacy of Echinacea and began to investigate methods to quantify the alkylamides along with other important compounds such as cichoric acid. At the time there was no published test methodology for alkylamides and the process of developing the highperformance liquid chromatography (HPLC) methodology took MediHerb a number of years. Once armed with the HPLC methodology for identifying quality in terms of alkylamide content, MediHerb worked with Echinacea growers to determine appropriate growing conditions and handling parameters to ensure optimum retention of the alkylamides.
We have established protocols to ensure optimum retention and stability of alkylamides during all phases of the production process; from receipt of the raw material to completion of the finished product. Alkylamides are very delicate compounds and are easily damaged or lost during processing, hence developing these protocols took many years to conclude.
