摘要：

Taurine-conjugated bile acids are an important group of biological metabolites. When investigated by negative-ion fast-atom bombardment collison-induced dissociation mass spectroscopy they show charge-remote fragmentations of the [M-H]- pseudomolecular ion. These fragmentations provide information on the positions of ring substituents remote from the charge site. In the present work we have compared the negative-ion fast-atom bombardment collision-induced dissociation spectra of six different conjugated bile acids.
