 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. \\

+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. \\
