Applications of direct analysis in real time-mass spectrometry (DART-MS) in Allium chemistry. (Z)-Butanethial S-oxide and 1-butenyl thiosulfinates and their S-(E)-1-butenylcysteine S-oxide precursor from Allium siculum

Original language description

Lachrymatory (Z)-butanethial S-oxide along with several 1-butenyl thiosulfinates was detected by DART mass spectrometry upon cutting Allium siculum, a popular ornamental Allium species used in some cultures as a spice. (Z)-Butanethial S-oxide isolated from the plant was shown to be identical to a synthetic sample. Its likely precursor, (RS,RC,E)-S-(1-butenyl)cysteine S-oxide (homoisoalliin), was isolated from homogenates of A. siculum, and a closely related species Allium tripedale, and fully characterized. Through use of LC-MS, a series of related ?-glutamyl derivatives were tentatively identified in A. siculum and A. tripedale homogenates, including ?-glutamyl-(E)-S-(1-butenyl)cysteine and its S-oxide, ?-glutamyl-S-butylcysteine and its S-oxide, and?-glutamyl-S-methylcysteine and its S-oxide. Because compounds containing the 1-butenyl group have not been previously identified in genus Allium species, this work extends the range of known Allium sulfur compounds. The general appli
