Chiral compounds of essential oils. Part XIII. Simultaneous chirality evaluation of geranium oil constituents

Abstract The chiral monoterpenoids cis/trans rose oxides, mennthone, isomenthone, linalol, α‐terpineol and citronellol are stereoanalysed simultaneously, using enantioselective multidimensional gas chromatography (enantio‐MDGC) and the column combination polyethylene glycol/heptakis(2,3‐di‐ O ‐acetyl‐6‐ O ‐ tert ‐butyldimethylsilyl)‐β‐cyclodextrin in OV 1701‐vi. The method is applied to the chirality evaluation of these monoterpenoids from geranium oils of different origin. The enantiomeric ratios are discussed in view of the origin assessment of geranium oils.
