 The seeds of wallflower contain glucocheiroline,​ which yields cheirolin (1-isothiocyanato-3-(methylsulfonyl)-propane,​ also the name of the essential oil of the seeds) on enzymatic cleavage. Cheirolin is obtained from defatted seeds by extraction with dry ethanol. \\ The seeds of wallflower contain glucocheiroline,​ which yields cheirolin (1-isothiocyanato-3-(methylsulfonyl)-propane,​ also the name of the essential oil of the seeds) on enzymatic cleavage.

 +Application of the vacuum headspace method to the picked flowers lead to higher amounts of mustard oil compounds in the concentrate. Compounds like 4-methylthio butyronitrile (1-5%) and 3-methylthio propylisothiocyanate (2-30%) originate from enzymatic processes which are started by destruction of plant tissue. Another main constituent of the vacuum headspace concentrate was anthranilic aldehyde. \\
