Fig. 3From: Metabolite identification of salvianolic acid A in rat using post collision-induced dissociation energy-resolved mass spectrometryFEER-MS3 spectra for monomethylated SAA metabolites compared with FEER-MS2 spectra for hydrolysis product anions. (A) Overlaid FEER-MS3 spectrum of m/z 211.06 for M25, along with FEER-MS2 spectra for D14 and D15 anions; (B) Overlaid FEER-MS3 spectra of m/z 327.09 for M23 and M26, along with FEER-MS2 spectra for F28 and F29 anionsBack to article page
