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 glucosinolates.Key words: Synthesis; mass spectrometric analysis; aromatic; indole; glucosinolates; structure; purity; fragmentation pathways
