Abstract:

Flowers of Arnica longifolia were investigated for the occurrence of sesquiterpene lactone glycosides. A mixture containing the two isomeric 11α,13-dihydro- and 11β,13-dihydro-4 H-tomentosin glucosides, previously isolated from A. amplexicaulis and A. mollis, together with the two isomeric 11α,13-dihydro- and 11β,13-dihydro-4H-carabrone glucosides were found in A. longifolia. All carbon and proton shifts of the glycosides could be assigned by their 2D-COSY and 2D-HETCOR spectra and spectroscopy of their respective aglycones, obtained via enzymatic hydrolysis.

Key words:

Arnica longifolia, Asteraceae - sesquiterpene lactones - sesquiterpene lactone glycosides - xanthanolides - xanthanolide glucosides - carabrone glucosides
