Figure 6: A full mass spectrum of AA-I from m/z 100 to m/z 1000, (a) electrospray ionization + mode showing considerable intensity of (M + NH4) + ions at m/z 359, (b) electrospray ionization mode showing (M-H)-ions at m/z 340, (c) daughter ion spectra of the ammonia additive precursor ions of AA-I at m/z 359. Distinctive fragments of ions of AA-I were observed at m/z 298
