Fig. 3: Identification of S-Alk(en)ylcysteine sulfoxides (CSOs) using UPLC-QTOF-MS.

a A summary of metabolites identified for 16 Asparagales species. b Extracted-ion chromatograms of isoalliin and alliin from nine Allium species. Plant photos were taken by Bing Liu, Xiao-Wei Xin, Xiao-Xiao Wang, and Ling-Yun Chen. c Secondary ion fragments for alliin and isoalliin are depicted as shaded areas on the chromatograms. Red numbers indicate the characteristic secondary fragment ion of alliin.
