Kchouk, Auteur Année de publication : 2011 Article en page(s) : pp. 471-476 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Citrus sinensis Rutaceae Juice volatiles Index. décimale : 646 Résumé : This paper reports on the composition of aroma compounds during blood orange maturity. Volatile compounds have been analyzed by gas chromatography. Terpenic fraction constitutes 94% of total aroma compounds of blood orange; limonene is the major monoterpenic hydrocarbon of this fraction, constituting 81% and 73% of total aroma.

The leaf oil of G. tapis was made up mainly of sesquiterpenoids where α-copaene (23.8%) and β-caryophyllene (14.4%) were the major components. The bark oil of G. tapis could be differentiated from its leaf oil due to its high content of linalool (13.0%), limonene (12.7%) and safrole (11.2%). Although the leaf oil and root oil of G. tapis were rich in sesquiterpenoids, different ones were found in this latter oil where the most abundant constituent was cyperene (16.2%). The leaf oil of G. tapisoides comprised almost entirely of monoterpenoids, of which 1,8-cineole (79.0%) was the most abundant component. The bark and the root oils of G. tapisoides were also rich in 1,8-cineole, but with considerable variation in levels of the minor constituents.

The oils obtained by hydrodistillation were analyzed for their constituents by means of GC-FID and GC/MS. Of the 36 compounds of A. nilotica, menthol (34.9%) and limonene (15.3%) were the two quantitatively significant constituents. α-Pinene (18.6%) was the only abundant compound among the 37 constituents of A. albida oil. The results differed considerably from previous data on the oil constituents of some previously studied Acacia species.

Large amounts of δ-3 carene, present in needles of A. nordmanniana and A. cilicica subsp. cilicica differentiated these species, since this compound is not found in the needles of other Anatolian firs and in those of European counterparts. The percentages of santene and germacrene-D as well as the ratio of percentage of β-pinene to percentage of myrcene can be used to distinguish carene-containing Turkish firs from each other. Remaining West Anatolian fir species (A. bornmülleriana, A. equi-trojani and A. cilicica subsp. isaurica) were found to have essential oils of the same qualitative composition. By cluster analysis using SPSS software, the Anatolian firs were divided practically into two groups, characterized by either existence or absence of δ-3 carene in needle extracts.

The composition of their essential oils was analyzed by capillary gas chromatography (GC) and mass spectrometry (MS). Eight chemotypes were defined, namely 1-octen-3-ol, (Z)-β-ocimene, geraniol, myrcene, 1,8-cineole, α-terpinyl acetate, germacrene B and geraniol/germacreneB. The composition of the hybrid oil can be characterized as intermediate comparing to its parental species, T. serpyllum L. and T. pulegioides L., according to the percentages of thymol, carvacrol, 1,8-cineole, germacrene B, geraniol and (Z)-β-ocimene. Three samples of the investigated T. × oblongifolius were moved from natural habitats into the experimental field collection and cloned annually in the ground under the same environmental conditions. Oil composition of these three samples was monitored in the fourth clonal offspring generation and compared with the oil composition of their parent plants from natural habitats. The results obtained by cloning showed that the composition of essential oil of the interspecific hybrid T. × oblongifolius is quite stable, most likely predetermined genetically.

The oil samples were analyzed for two consecutive years. (E)-Cinnamaldehyde, which was the principal component, was higher in the first year oil samples but lower in the second year samples. Similarly, (Z)-cinnamaldehyde was 5.8–7.1% in the first year oils and 1–1.1% of the second year oils. Linalool content varied (6.4–8.5% and 5.7–16.2%, respectively) in first and second year oil samples, while (E)-cinnamyl acetate was higher (10.0–22.7%) in oil samples of the second year collection. Using a 10% heptakis(2,3-di-O-methyl-6-O-tert-butyldimethylsilyl)-b-cyclodextrin as the chiral stationary phase, optically pure (3S)-(+)-linalool was found in both the oil samples leading to complete enantiomeric excess for (3S)-(+)-enantiomer.

Analyses of the compound were done using GC and GC/MS. Between 16–22 compounds were identified, accounting for 90.1–98.5% of the oil samples. The characterized oil samples show a high percentage of oxygen-containing monoterpenes in all the localities. 1,8-Cineole was found to be the main component in all the samples being present in the range of 44.4–85.4%. Others prominent compounds of the oils were α-pinene (6.2–27.8%), α-terpineol (tr-6.8%) and E-(β)-ocimene (tr-6.7%).
