This article reviews papers published over the period 1995–1998 dealing with the application of cyclodextrin derivatives (CDs) as chiral selector for direct enantiomer GC separation of volatile optically active components in the essential oil, extract, flavour and aroma fields. For each application, the racemate analysed, the CD employed as chiral selector and the matrix investigated are reported. The applications are grouped by analytical technique employed: capillary gas chromatography and capillary gas chromatography–mass spectrometry (GC and GC–MS); two-dimensional gas chromatography (GC×GC); capillary gas chromatography–isotope ratio-mass spectrometry (GC–IRMS); liquid chromatography–capillary gas chromatography (LC–GC).
