Tussilagine and isotussilagine: two pyrrolizidine alkaloids in the genus arnica1.
In flowerheads of ARNICA MONTANA, A. CHAMISSONIS ssp. FOLIOSA, A. AMPLEXICAULIS, and A. SACHALINENSIS, traces of the non-toxic pyrrolizidine alkaloids tussilagine and isotussilagine were detected. Their identity was unambiguously confirmed by direct comparison (TLC, GC, GC/MS) with the authentic samples.
