Chiral compounds of essential oils. Part XVII. simultaneous stereoanalysis of cymbopogon oil constituents

Using enantioselective multidimensional gas chromatography (enantio-MDGC) and the column combination polyethylene glycol/heptakis (2,3-di-O-acetyl-6-O-ter-butyldimethylsilyl)-β-cyclodextrin in OV 1701-vi, the chiral monoterpenoids cis/trans-rose oxides, linalol, citronellal, citronellol and terpinen-4-ol were stereoanalysed simultaneously. The method is applied to chirality evaluation of these compounds in Cymbopogon (Citronella) oils. The enantiomeric distributions are discussed as indicators to the authenticity of these essential oile
