Abstract

Arnica montana and Arnica chamissonis ssp. foliosa flowers are often adultered by blending them with those from Heterotheca inuloides. TLC, HPLC, and TSP LC/MS have been proposed to detect this kind of falsification. A new method based on micellar electrokinetic chromatography (MEKC) has been developed. This procedure permits us to characterize rapidly each drug and to detect easily falsifications from H. inuloides in Arnica drugs.
