ABSTRACT
The article discusses a single-laboratory validation study for the determination of major phenolic compounds in Echinacea raw materials and finished products using high-performance liquid chromatography (HPLC) and ultraviolet detection. Specifically, the study was run to determine if cichoric acid, a major phenolic component of Echinacea pupurea (L.) Moench and E. angustifolia DC degrades during extraction and HPLC analysis. No significant degradation was noted over an extended testing period.
