Fig. 18. Some proposed glucosinolates (GSLs) in need of more evidence. (A) Two GSLs suggested from MS to be isomers of [3], but without general NMR evidence or published MS/MS evidence for the position of the acetyl groups at the rhamnose residue, as opposed to the glucose residue or another isomer. (B) 2-Hydroxy-8-(methylsulfinyl)octyl GSL suggested from MS/MS evidence but without NMR evidence.
