“…13 C-Labeled limonene, 1-methyl-4-(1-methyl-(2-13 C)-ethenyl)-cyclohexene, was synthesized by means of the Witting-reaction. 15) The labeling reagent, 4.9 mmol 13 CH 3 P(C 6 H 5 ) 3 I, was added at 209 C over 5 min to a solution of 4.9 mmol NaH in 5 ml of DMSO, which had been prepared while stirring at below 709 C, and the mixture stirred for 20 min. After adding 5.0 mmol of acetyl-1-methylcyclohexene at 209 C over 5 min, the reaction mixture was stirred for 2.5 hr at room temperature.…”

The isotope ratio of monoterpene hydrocarbons in citrus essential oils of different origins was measured by ordinary high-resolution gas chromatography-mass spectrometry (HRGC-MS). The isotope ratio (Ir) was determined by the ratio of the isotope peak intensity (m/z 137) to the molecular mass peak intensity (m/z 136) of the monoterpene hydrocarbons. The accuracy of Ir was examined by measuring monoterpene hydrocarbon standards and 13C-labeled compounds. The isotope fingerprints based on the values of monoterpene hydrocarbons from lemon, lime and yuzu essential oils were determined. These citrus essential oils were also discriminated by a principal component analysis of their Ir data. The characteristic vectors showed that alpha-terpinene, beta-pinene and beta-phellandrene were important components for distinguishing between the citrus species. It is suggested that this technique will be applicable to evaluate the quality, genuineness and origin of citrus fruits and their products.

“…Study of the enantiomeric compositions of terpenoids is useful for identifying adulterated foods and beverages, controlling and monitoring processing conditions, and for determining the effects of storage on such products. Mosandl and co-workers [69] applied enantio-MDGC coupled with isotope ratio mass spectrometry (IRMS) to determine the chiral composition of (+/À)-r-menth-1-en-9-ol in Anethum graveolens L. plant, highlighting enhanced peak purity for the ease of direct enantiomer measurement. A fast enantio-MDGC configured with micro-bore columns in both dimensions was demonstrated by Mondello and co-workers [70] by isolating 18 enantiomeric pairs within 10 min.…”

Modern gas chromatography, with the development of advanced analytical techniques, has become a fundamental tool for the separation and characterization of plant extracts. These last issues are absolutely important if considering the widespread use of plant derivatives not only in pharmaceutical/food industry but also, for a large part, in traditional and alternative medicine, which require a high level of quality and safety. Hence, the development of new, powerful hyphenated GC techniques were reviewed in this article, including Gas Chromatography-Mass Spectrometry (GC-MS), Solid Phase Microextraction-Gas Chromatography (SPME-GC), Gas Chromatography-Fourier-transformed Infrared Spectroscopy (GC-FTIR), Multidimensional Gas Chromatography (MDGC) and Comprehensive Gas Chromatography (GCxGC). Several applications of each technique were reported and illustrated.
