Titre : Characterization of volatile compounds in selected citrus fruits from Asia—part II: : Peel oil Type de document : texte imprimé Auteurs : Jorry Dharmawan, Auteur ; Stefan Kasapis, Auteur ; Philip Curran, Auteur Année de publication : 2008 Article en page(s) : pp. 21-24 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Citrus nobilis var. microcarpa Citrus sinensis Citrus reticulate Rutaceae Essential oil composition Limonene Myrcene γ-terpinene Résumé : The volatile compounds of the hand-pressed peel oil from the selected citrus fruits from Asia, namely Indonesian Pontianak oranges (Citrus nobilis Lour. var. microcarpa Hassk.), Indian Mosambi (Citrus sinensis Osbeck) and Philippine Dalandans (Citrus reticulata Blanco), were characterized by GC-FID and GC/MS. A total of 32 compounds were found in Pontianak orange, 29 in Mosambi and 37 compounds in Dalandan peel oils. Limonene dominated the composition of each of the oils and most of the compounds were present in the concentrations less than 0.1%. The absence of some important contributor compounds to mandarin family in Pontianak orange show that it is a mandarin that has unique characteristic flavor. The characteristic compound of sweet orange oil, δ-3-carene, was found in Mosambi peel oil. The presence of γ-terpinene in Dalandan was exceptionally high (4.3%) compared with other cultivars. Isopiperitenone was the tentatively-identified volatile compound not frequently reported in other citrus fruits found in Dalandan peel oil. It could be the important contributor to the characteristic aroma of Dalandan despite its trace amount.

Limonene (25.8% and 24.6%), (E)-β-ocimene (20.3% and 21.7%) and β-pinene (12.0% and 14.2%) were the major compounds in the unripe and semi-ripe stages, respectively, while γ-muurolene (25.8%), β-caryophyllene (18.4%) and α-humulene (15.4%) became the major compounds in ripe fruits. The concentration of monoterpenes was high in the unripe and semi-ripe stages and decreased afterwards, while sesquiterpenes were intensively synthesized only in the last part of the ripening process.

The oils of C. articulatus var. articulatus and C. articulatus var. nodosus showed mustakone (9.8–14.5% and 6.6–14.5%, respectively) and caryophyllene oxide (4.6–10.8% and 5.4–13.7%, respectively) as major components. The oils of C. prolixus were characterized by a higher amount of caryophyllene oxide (6.9–26.9%), α-cyperone (13.5–20.6%), and 14-hydroxy-9-epi-β-caryophyllene (9.6–16.7%). α-cyperone (22.8%) and cyperotundone (12.1%) were the main compounds from the oil of C. rotundus. The oils of the two varieties of C. articulatus differed from those of the two other species studied here by the presence of mustakone. α-Pinene and β-pinene were higher in the oils of C. articulatus than in those of C. prolixus and C. rotundus. Concerning the two varieties of C. articulatus cultivated in Pará for commercialization in perfumery, we agree that the minor quantitative variations observed in the chemical composition probably do not modify the scent of their oils to any great extent.

The Ghanaian oils showed a significant variability in their chemical composition and five chemotypes were identified. The oil from Aframso Bridge was yellow with a refractive index (RI) of 1.4853, density (DE) of 0.894 and was dominated by linalool (29%) and germacrene D (28%) with fresh, and slightly medicinal and spicy aroma. Ghanaian samples from Seikwa, Buem Nsuta and Golokwati were characterized by high levels of sesquiterpenes (45–70%). The aroma was medicinal/herbaceous and the color was typically yellow, except the oil from Seikwa which was dark orange-yellow, RI ranging from 1.4920 to 1.5043 and DE 0.893 to 0.93 D. The oils from Nyankpala, Sari, Amantin, Atebubu and Kobre contained high levels of aromatic monoterpenes (p-cymene 14–19%, thymol 30–40%, and thymyl acetate 14–17%). The oils were characterized as spicy and the color ranged from dark yellow (Nyankpala, Sari and Kobre) to yellow (Atebubu and Amantin) (RI 1.4969 to 1.5020, DE 0.9207 to 0.9344). The oil from Ho showed lower levels of aromatic monoterpenes and higher levels of farnesol, the oil was yellow and aroma woody/camphoraceous (1.492 RI, 0.893 D). In contrast, oils from Nsawkaw and Kofiase-Kubesiase were composed of high amounts of 1,8-cineole (43–47%), sabinene (12–15%, respectively), and were light yellow (RI 1.4695 to 1.4712, DE 0.8995 to 0.9002). A cluster analysis was performed for comparison and characterization of L. multiflora oils from Ghana other 33 oils from 10 African countries. The oils from Ghana with these five chemotypes appeared to be the most diverse oils in Sub-Saharan Africa.

The oil was devoid of acorenone-B and differs from the oils produced from other regions with respect to the sesquiterpenoid content. The chemical composition also revealed that the major categories are long chain esters (41.6%) and oxygenated monoterpens (10.9%). High concentration of isoamyl hexanoate and absence of acorenone-B, intermediol, neointermedeol in the oil makes the grass as a distinct chemo-variant of the species reported so far.

Minimal inhibitory concentration (MIC) and minimal lethal concentration (MLC) were used to evaluate the antifungal activity against yeasts (C. albicans, C. tropicalis, C. parapsilosis, C. guillermondii, C. krusei, Crytococcus neoformans), Aspergillus (A. niger, A. fumigatus, A. flavus) and dermatophyte strains (Microsporum canis, M. gypseum, Trichophyton rubrum, T. mentagrophytes, Epidermophyton floccosum). The oils exhibited significant antifungal activity against dermatophyte strains with MIC between 0.16–0.64μL/mL.

Titre : Effect of mono- and bicyclic monoterpenoids upon dictyostelium minutum and dictyostelium macrocephalum Type de document : texte imprimé Auteurs : Jiyoung Hwang, Auteur ; Hiromitsu Hagiwara, Auteur Année de publication : 2008 Article en page(s) : pp. 91-95 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Dictyostelium minutum Dictyostelium macrocephalum Cellular slime molds (4S)-(+)-carvone (1S)-(-)-verbenone (1R)-(-)-fenchone (1R,5R)-(+)-β-pinene Inhibition Enhancement Résumé : We have studied the effect of four monoterpenes on the growth of two cellular slime molds, Dictyostelium minutum Raper and D. macrocephalum Hagiwara, Yeh et Chien. (4S)-(+)-carvone was the monocyclic monoterpene we tested, while (1S)-(-)-verbenone, (1R)-(-)-fenchone, and (1R,5R)-(+)-β-pinene were the bicyclic monoterpenes we employed.
One μL of four different concentrations (0.006M, 0.06M, 0.6M and 6M) of each monoterpene were applied to both species, through the use of the Disk Volatilization Technique. (4S)-(+)-carvone possessed a superior inhibitory activity against both D. minutum and D. macrocephalum, at 0.6M concentration (p≤0.001), while growth rate enhancement occurred after application of (4S)-(+)-carvone at concentrations of 0.006M and 0.06M on D. minutum and D. macrocephalum (p<0.05).
The inhibitory effects of the monoterpenes on the growth of D. macrocephalum increased proportionally to the applied compound concentrations in most cases. When the bicyclic monoterpenes (1R)-(-)-fenchone and (1S)-(-)-verbenone were administered to D. macrocephalum, however, it was greatly inhibited even at low concentrations (p<0.05 and p<0.001). The bicyclic monoterpene (1R,5R)-(+)-β-pinene inhibited the growth rate of D. minutum and D. macrocephalum at most concentrations, but at 0.006M concentration (1R,5R)-(+)-β-pinene caused slight enhancement.
Microscopic examination of changes in the shapes of the fruiting bodies matched the effects observed on the growth rates. These results suggest that the inhibitory or enhancing effects of the selected monoterpenes on both D. minutum and D. macrocephalum depend on the number of cyclic skeletons as well as the concentration of the individual compounds.ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2008.9699431 [article] Effect of mono- and bicyclic monoterpenoids upon dictyostelium minutum and dictyostelium macrocephalum [texte imprimé] / Jiyoung Hwang, Auteur ; Hiromitsu Hagiwara, Auteur . - 2008 . - pp. 91-95.
