Abstract
From a comparison of phytosterol and triterpenoid patterns of severalSymphytum officinale cytotypes,S. asperum and their interspecific hybrids,S. ×uplandicum, which were obtained from thin layer chromatography and gaschromatography (also in combination with mass spectrometry), the hybrid character of the latter taxon is clearly shown. The specific value of the triterpenoid isobauerenol as a chemotaxonomical marker within this group is discussed in some detail.
