Abstract

The synthesis and mass spectrometric analysis of aromatic and indole glucosinolates were investigated in this study. It was found that besides the peaks at m/z 75, 80, 96, 97, 195, 259, 275, the mass spectra also contained peaks that served unambiguously to identify a particular glucosinolate based on the loss of SO3 from its unambiguousness to identify a specific ion [M-K]-, and other ions such as [R-C(=NOH)S]-and [R-C(S)OSO2]-generated from the fragmentation of the backbone skeleton of GLs.
