title: The components of the venom of a spider Scodra griseipes. 2. Structural information on biogenic amines using tandem mass spectrometry.
abstract: Biogenic amines, which are components of tarantula Scodra griseipes venom, are studied using tandem mass spectrometry. Their heptafluoropropionic (PFP) derivatives are ionized under electron impact and isobutane-chemical ionization. Daughter- and parent-ion mass spectra under collisionally activated dissociation conditions provide a more detailed study of such derivatives. Discrimination of di(PFP)amines and tri and tetra(PFP)amines is possible because of the presence of diagnostic ions induced by collision.
