## Abstract The fragmentation pathways of deprotonated cyclic dipeptides have been studied by electrospray ionization multiβstage mass spectrometry (ESIβMS^__n__^) in negative mode. The results showed that the fragmentation pathways of deprotonated cyclic dipeptides depended significantly on the di

The magnesium, nickel, copper, zinc and vanadium metalloporphyrins from octaethylporphyrin, etioporphyrin I and tetraphenylporphyrin were characterized using electrospray ionization mass spectrometry (ESI-MS). The ion abundance of each of the porphyrins present in binary mixtures was monitored as a
Ginsenosides R(b1), R(b2), R(c), R(d), R(e), R(f), R(g1), R(g2) and F(11) were studied systematically by electrospray ionization mass spectrometry in positive- and negative-ion modes with a mobile-phase additive, ammonium acetate. In general, ion sensitivities for the ginsenosides were greater in th
