Chiral compounds of essential oils. Part XVI. Enantioselective multidimensional gas chromatography in authenticity control of balm oil (Melissa officinalis L.)

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, octan-3-ol, oct-1-en-3-ol, linalol, citronellal, citronellol and citronellic acid methyl ester were stereoanalysed. The method is applied to chirality evaluation of these compounds from balm oils. The enantiomeric distributions are discussed in order to assess the authenticity of this essential oil
