Naturally occurring nucleosides and nucleobases form inclusion complexes with b-cyclodextrin. These host-guest complexes could be detected by fast atom bombardment mass spectrometry. The collision-induced dissociation spectra of the protonated complexes showed mainly ions related to the guest molecu

Complexation of aluminum ions {AI(III) in glycerol} with a-amino acids has been studied by FAB mass spectrometry. Twelve a-amino acids and cysteine methyl ester interact with different Al(II1)-containing ions and form several cluster ions such as [M+117]', [117={Al(LII)+glycerol-2H}]; [M+231]+, [231
2-Acetyl-1-pyrroline (1), 2-propionyl-1-pyrroline (2) and 5-acetyl-2,3-dihydro-1,4-thiazine (3), roast smelling odorants in food, form stable inclusion compounds with b-cyclodextrin. Fast atom bombardment (FAB) mass spectra of such complexes in thioglycerol showed abundant [ G + Hs + Mx + H ] ' ions
