A chromatogram from the GC-MS/MS analysis of AECK-DD in fresh shallot. 13C2-AECK-DD was added to the shallot-containing 100 mM phosphate buffer, pH 7.4, at a final content of 1 nmol per 1 g shallot. SRM of m/z 328 to m/z 268 for AECK-DD (upper panel) and of m/z 330 to m/z 270 for 13C2-AECK-DD (lower panel) was performed. The AECK-DD content is estimated to be about 7 pmol/g shallot.
