The extract obtained by solid‐liquid extraction with pentane‐dichloromethane (2+1, v/v) from dry mugwort ( Artemisià vulgaris L.) herb was fractionated by means of gel permeation chromatography (GPC) and subsequent middle‐pressure liquid chromatography (MPLC). Capillary gas chromatography (HRGC) and combined HRGC techniques, i.e. HRGC‐mass spectrometry (HRGC‐MS) and HRGC‐Fourier transform infrared spectroscopy (HRGC‐FTIR) of the separated MPLC fractions revealed the occurrence of 54 additional volatiles not described as yet in A. vulgaris herb. Among them, chiral evaluation of y‐nonalactone carried out by on‐line coupled multidimensional gas chromatography‐mass spectrometry (MDGC‐MS) revealed a distribution of ( R): (S) = 34:66%.
