Chemotaxonomic markers in Digitalideae (Plantaginaceae)

Members of the genera Digitalis, Isoplexis, Erinus and Lafuentea were studied for iridoids, caffeoyl phenylethanoid glycosides and main carbohydrates. Among the isolated compounds were the new tyrosol mannoside (sceptroside) and the new iridoid glucoside erinoside. The chemosystematic significance of the isolated compounds was discussed.
