cis / trans Rose oxides, linalol, citronellol and carvone are widespread natural fragrance compounds and well known among the genuine constituents of rose oils. Using enantioselective multidimensional gas chromatography (enantio‐MDGC) and the column combination Carbowax 20 M/heptakis(2,3‐di‐ O ‐acetyl‐6‐ O ‐ tert ‐butyldimethylsilyl)‐β‐cyclodextrin in OV 1701‐vi the direct and simultaneous stereoanalysis of these chiral fragrance compounds is achieved. The method is applied to the chirality evaluation of cis / trans rose oxides, linalol and citronellol from authentic Bulgarian and Turkish rose oils as well as commercially available rose oils. The enantiomeric ratios of genuine constituents from rose oils are discussed as indicators of naturalness.
