N2 - Tandem mass spectrometry with a four-sector type mass spectrometer was used to elucidate the structures of minor components of the peptidyl antibiotic P168s (leucinostatins). As N-terminal fragments, ions by B-type cleavage were dominant, while V-type cleavages were observed along with X, Y, and Z types as C-terminal ions. The V-type ions were predominant in the cleavages of the amino terminals of leucyl and hydroxyleucyl residues. The structures of several minor components could be deduced from the tandem mass spectra.
