✦ Synopsis

The electron impact-mass spectra as well as the complementary chemical ionization-mass spectra (with the reactant gas ammonia) of various structural types of sesquiterpene lactones isolated from Achillea species are discussed in respect to the important information either gained by fragmentation patterns or by the quasimolecular ions.
