Titre : Chemotypes in melaleuca quinquenervia (Cav.) S.T. blake (Niaouli) from benin using multivariate statistical analysis of their essential oils Type de document : texte imprimé Auteurs : J. D. Gbenou, Auteur ; M. Moudachirou, Auteur ; Jean-Claude Chalchat, Auteur Année de publication : 2007 Article en page(s) : pp. 101-104 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Melaleuca quinquenervia Myrtaceae Essential oil composition Multivariate statistical analysis Chemotypes 1,8-cineole Viridiflorol Seasonal influence Résumé : Forty compounds have been characterized by GC and GC/MS and relative retention times in 300 samples of Niaouli (Melaleuca quinquenervia) oils collected on 75 different trees during four seasons. Twenty-one compounds were submitted to multivariate statistical analyses using Principal Component Analysis (PCA). Factorial Discriminant Analysis (FDA) revealed the presence of three chemotypes. Chemotype I is already known (1,8-cineole; 50%), chemo-type II had an equal content in 1,8-cineole (33%) and viridiflorol (32%). The third (chemotype III) was characterized by a high content in viridiflorol (50%). The 1,8-cineole chemotype represented 58% of three populations. Seasonal differentiation does not occur, showing that Niaouli oil composition is stable all year.

Ginger oil was isolated by hydrodistillation from fresh ginger. Fresh ginger was dried and the oil was isolated by hydrodistillation from dry ginger (sun-dried and drier-dried). The oils were analyzed by GC and GC/MS. It was found that geranial (24.2%) and zingerone (14.2%) were the major compounds in the original aroma of fresh ginger and their contents decreased during processing. It was observed that the hydrocarbon content of the oil increased and the oxygenated compounds decreased as ginger was processed into dry ginger and ginger oil.

A survey of Juniperus oils revealed that these compounds were found in: three serrate leaf junipers (J. angosturana, two varieties of J. coahuilensis, and J. pinchotii). Coahuilensol was also found in the oils of two smooth leaf junipers of the western hemisphere (J. virginiana var. virginiana and J. v. var. silicicola); three multiple seeded, smooth leaf junipers of the eastern hemisphere (J. semiglobosa, J. semiglobosa var. talassica, and J. thurifera). The phenolic compounds were not found in section Juniperus, section Caryocedrus or in the one seeded, smooth leaf junipers of the eastern hemisphere. Coahuilensol has been previously reported as 2-(2-propenyl)-phenol (tentative). The leaf oils of J. angosturana J. coahuilensis, J. coahuilensis var. coahuilensis, J. monosperma and J. pinchotii were re-examined based on fresh oil collections and the compositions are reported. NMR data and mass spectra of the three 3-methyl phenols are presented to aid in future identification.

A survey of Juniperus oils revealed that these compounds were found in: three serrate leaf junipers (J. angosturana, two varieties of J. coahuilensis, and J. pinchotii). Coahuilensol was also found in the oils of two smooth leaf junipers of the western hemisphere (J. virginiana var. virginiana and J. v. var. silicicola); three multiple seeded, smooth leaf junipers of the eastern hemisphere (J. semiglobosa, J. semiglobosa var. talassica, and J. thurifera). The phenolic compounds were not found in section Juniperus, section Caryocedrus or in the one seeded, smooth leaf junipers of the eastern hemisphere. Coahuilensol has been previously reported as 2-(2-propenyl)-phenol (tentative). The leaf oils of J. angosturana J. coahuilensis, J. coahuilensis var. coahuilensis, J. monosperma and J. pinchotii were re-examined based on fresh oil collections and the compositions are reported. NMR data and mass spectra of the three 3-methyl phenols are presented to aid in future identification. ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2007.9699247

Current methods of heartwood oil assessment of standing trees remain largely untested and unreliable. Core sampling of 22 S. album trees at fixed heights followed by solvent extraction of core samples and subsequent analysis was correlated to distilled yields of wood from the same trees. Oil contents of 10-year-old sandalwood trees generally decreased exponentially up the height of the tree, with considerable variation amongst the population. From these trends, core sampling was used to estimate oil yields but large discrepancies existed, and only relative differences could be described. Gas chromatography yielded the most informative results for each core, particularly that the oil composition varied little at 30 cm or at 100 cm, however, there was a slightly higher proportion of sesquiterpene hydrocarbons in samples taken from 100 cm than those from 30 cm. The proportion of sesquiterpene alcohols was generally higher in 30 cm wood cores than in 100 cm samples.

The oils and hydrosols were assayed against four fungi, Aspergillus nidulans, Trichophyton mentagrophytes, Leptosphaeria maculans and Sclerotinia sclerotiorum, using a disc diffusion method. No evidence of antifungal activity was observed with any of the hydrosols. In contrast, all oils displayed some antifungal activity. Lavandula angustifolia and the three examples of Lavandula x intermedia oil demonstrated the greatest effect against A. nidulans and T. mentagrophytes while L. stoechas was particularly effective against the two agricultural fungi, L. maculans and S. sclerotiorum. No significant difference was observed between the antifungal activity of L. angustifolia oils derived from European and Australian grown plants. These results suggest that the oils from various Lavandula species may be useful in the treatment of fungal infections.

Forty-two percent of the cells present in lymphocyte cultures stimulated by the oil were CD8(+) T cells and showed higher IFN-γ levels than non-stimulated cultures (p < 0.05). According to these results, the oil was considered to be a Th1 deviation inducer, inhibiting the immediate-type allergic reaction.

Titre : Chemical composition and antimicrobial activity of the flower oil of russowia sogdiana (Bunge) B. fedtsch. (Asteraceae) from China Type de document : texte imprimé Auteurs : Manliang Tan, Auteur ; Ligang Zhou, Auteur ; Meng Qin, Auteur Année de publication : 2007 Article en page(s) : pp. 197-200 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Russowia sogdiana Asteraceae Essential oil composition limonene Antimicrobial activity Résumé : An essential oil, which was obtained by water distillation from Russowia sogdiana (Bunge) B. Fedtsch. flowers, was analyzed by GC and GC/MS. The main constituents were identified as limonene (15.9%), trans-α-bergamotene (5.6%), salvial-4(14)-en-1-one (3.8%), carvone (3.6%), p-cymene (3.6%), trans -carveol (3.2%). Thirty-two components were separated and identified which accounted for over 62.1% of the total essential oil. The antimicrobial activity of R. sogdiana oil was studied using broth dilution test on seven bacterial strains, using mycelial growth test on three fungal strains. The oil exhibited a broad spectrum antibacterial activity against Gram-positive (Bacillussubtilis, Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli, Erwinia carotovora ssp. carotovora, Pseudomonas lachrymans, Xanthomonas vesicatoria, Agrobacterium tumefaciens) with minimum inhibitory concentration (MIC) values ranging from 0.2 mg/mL to 0.8 mg/mL. The oil also showed an important antifungal activity against fruit pathogenic fungi Glomerella cingulata, Botryodiplodia theobromea and Venturia pirina. Maximum antifungal activity was observed against G. cingulata mycelial growth which percentage inhibition was 51.8% at concentration of 100 μg/mL.
