    Tandem mass spectrometry combined with Fourier transform ion cyclotron resonance (FTICR) has been the basis for rationalizing the fragmentation mechanisms of antifungal macrolides nystatin A1, amphotericin B and pimaricin. The positive ion mass spectra were not informative, however, the dissociation of deprotonated molecules led to structurally significant ring-opened fragments. Using this approach of tandem FTICR mass spectrometry (MS/MS) and electrospray ionization (ESI) coupled with high-performance liquid chromatography (HPLC), eleven macrolide natural analogues or degradation products were characterized in the nystatin mixture
