TLC and HPLC Analysis of Alkamides in Echinacea Drugs1,2.

R Bauer1, P Remiger.   

Abstract

HPLC and TLC methods are presented for the analysis of the alkamides in ECHINACEA PURPUREA, E. ANGUSTIFOLIA, and E. PALLIDA. The roots of E. PURPUREA and E. ANGUSTIFOLIA contain different structural types of alkamides, while the roots of E. PALLIDA were almost void of amides. In contrast, the aerial parts of the three ECHINACEA species yielded very similar alkamide patterns. The methods are suitable for the analytical characterization and standardization of the three species.
