Summary

The fragmentation of some C1-OH eudesmanolides has been studied with the aid of an isotopic label and high-resolution mass spectrometry. It has been shown that the most characteristic fragmentation is that with the cleavage of the C1-C10 and C4-C5 bonds. The sesquiterpene lactone arabsin has also been assigned to the C1-OH eudesmanolides and this has been confirmed by its conversion into anhydroarabsin — an α,β-unsaturated ketone.
