Volatile Constituents in Dried Roots of Isatis tinctoria L. (Brassicaceae)

Abstract The root volatile constituents of Isatis tinctoria L. (Brassicaceae) have been studied by GC-FID, and solid-phase microextraction and gas chromatography/mass spectrometry (SPME-GC/MS). Thirty components were fully characterized by mass spectra, linear retention indices, and injection of standards; the average composition (ppm) as single components and classes of substances is reported. The root volatiles in I. tinctoria were characterized by a high amount of 3-butenyl isothiocyanate, which accounted for about 82% of the total volatile fraction.
