The mass spectral fragmentation pattern of glutathionyl-S-caffeoylquinic acid in (A) positive and (B) negative ionization modes. The MassFragment™ software facilitated structural elucidation and compound identification, using the spectral patterns in both ionization modes. In ESI(–), the precursor ion is 658.15 [M-H], while the main fragment ions are 515.10 [M-H-C5H10N2O3], 385.05 [M-H-C10H16N3O6] and 191.02 [M-H-C19H22N3O9S]. In ESI(+) mode, the precursor ion is 660.17 [M + H]+, while the main fragment ions are 468.13 [M + H-quinic acid+] and 307.17 [M + H-C16H17O9]+. These fragments correspond to what has been described in [26]
