“…Two complementary but distinct strategies can be adopted: (1) the best known strategy is based on a second dimension in separation (conventional heart-cut two-dimensional GC, [29,30] or comprehensive GC [31,32] ); and (2) the other strategy uses MS as a second dimension in detection. [33,34] Advantages and limits of both approaches are well known, although recently mass spectrometry as a second dimension in detection has gained further interest because of the role it can play in speeding up ES-GC analysis. Fast ES-GC analysis can successfully be achieved using: (1) short conventional or narrow-bore columns; (2) MS as detector to locate the enantiomers in the chromatograms and linear retention indices to identify them; [35] and (3) temperature rates up to 10°C/min.…”

The term 'volatile fraction' is a framework including a range of approaches and/or techniques, which produce samples that, while they may have different compositions, are representative of the volatiles characterizing a vegetable matrix, e.g. headspace, essential oils, flavours, fragrances, aromas and extracts prepared through specific techniques. Its study requires analytical methods and technologies able not only to evaluate its composition exhaustively but also to monitor variations of its profile and to detect trace components characterizing the plant being investigated. The strategies of analysis have changed significantly over the last 15-20 years because of the introduction of new approaches, in particular: (i) solventless sample preparation techniques; (ii) fast gas chromatography and related techniques; (iii) new analytical techniques, such as comprehensive gas chromatography (GC); (iv) new operative strategies based on approaches developed for other fields and applied to plant analysis; and (v) data elaboration strategies producing a higher level of information. This article is a short overview on (1) the advancement of analytical techniques and how they can influence strategies and approaches to study the plant volatile fraction, and (2) enantiomer GC and GC-mass spectometry separation using cyclodextrins as chiral selectors.

“…The elution order of each enantiomeric pair was assigned by comparison of retention time with those of authentic standards and confirmed with previous reports. 13,16,27 Linear retention indexes were obtained by co-injection of authentic standards with a homologous series of n-alkanes in GC-MS using a different temperature ramp (70 °C, 5 min isothermal; 3 °C min -1 up to 200 °C hold time 5 min) with the other chromatographic conditions having the same value as described before.…”

Some Eucalyptus species produce oils with biological activities and the effect of their interspecific hybridization on the enantiomeric composition of terpenes has not been reported. The enantiomeric excesses of monoterpenes in the essential oil of Eucalyptus grandis × E. tereticornis and its parental taxa were determined by gas chromatography-mass spectrometry (GC-MS), and to resolve coelutions problems by preparative high performance liquid chromatography (HPLC) and GC-MS with two columns in series. The essential oil composition of the hybrid presented qualitative and quantitative differences with the composition of its parental taxa. Great differences were found for the enantiomeric ratio in monoterpene alcohols among the three essential oils. Our results suggest that the enantiomeric analysis can be a reliable method for the study of how the interspecific hybridization can module the enantiomeric chemical profile in Eucalyptus essential oils. These results suggest the use of interspecific hybridization to improve or expand the source of bioactive compounds.
