GC-MS, GC-O and enantio-GC investigation of the essential oil of Tarchonanthus camphoratus L.

The volatile fraction of Tarchonanthus camphoratus L. has been studied by means of gas chromatography-mass spectrometry (GC-MS) and GC-FID, leading to the determination of 90 components whose major were alpha-pinene (14.7 g/100 g), eucalyptol (14.8 g/100 g) and fenchyl alcohol (12.2 g/100 g). Gas chromatography-olfactometry (GC-O) has been applied to the evaluation of the olfactive notes and their intensity. Also, the enantiomeric distribution of some relevant constituents has been assessed by enantio-GC through the use of a chiral cyclodextrin-based stationary phase.
