PRBVIOUSLY we have shown (l-5) that the mass spectrometric method can be successfully used for rapid determination of cyclic di-, tetra-end hexsdepeipeptide structures with various sequences of amino and hydroxy acid residues.

Collisionally activated dissociation (CAD) spectra of protonated molecules of cyclopeptides and cyclodepsipeptides obtained with two different mass spectrometry systems were compared. Fragmentations were obtained either from collisions induced in the ion source of an electrospray mass spectrometer f
