Abstract

Abstract: Electrospray ionization mass spectrometry was applied to investigating the noncovalent interaction between ginsenosides and cytochrome c. Several noncovalent complexes with different stoichiometric relationships were observed from the mass spectra. The competition experiment was performed to validate the results. The dissociation constants of the complexes obtained by different systems are consistent with each other.

Key words: Electrospray ionization mass spectrometry, Ginsenoside, Cytochrome c, Noncovalent complex
