Titre : Essential oil of eaglewood tree : A product of pathogenesis Type de document : texte imprimé Auteurs : Phatik Tamuli, Auteur ; Paran Boruah, Auteur ; Subhan C. Nath, Auteur Année de publication : 2006 Article en page(s) : pp. 601-604 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Aquilaria agallocha Chaetomium globosum Fusarium oxysporum Thymelaeaceae Essential oil composition Hexadecanoic acid Résumé : The essential oil of eaglewood tree (Aquilaria agallocha Roxb.) has been considered to be a pathological product. An investigation was carried out to study the difference in composition of oils obtained from healthy, naturally infected and artificially inoculated eaglewood using GC and GC/MS analyses. This investigation showed a marked difference in the oil compositions among the treatments with regards to their quality. Valerianol (3.0%) and tetradec-anioc acid (7.1%) contents were recorded higher in the oils of naturally infected plants than in that of healthy ones (0.1% and 6.9%, respectively). Pentadecenoic acid was totally absent in the oils of healthy, whereas it was found in a greater amount (6.8%) in the oil of naturally infected plants. In contrast, dodecanoic acid (3.1%), pentadecanoic acid (6.2%), hexadecanoic acid (31.5%) and octadecanoic acid (4.1%) were found in a higher amount in the oils of healthy plants, while the oils obtained from naturally infected plants contained lower amounts of these components (2.5%, 4.8%, 20.0% and 1.0%, respectively). The oils obtained from the inoculated plants showed almost similar distribution of the components with healthy plants.

The leaf oil of D. struckoilicum contained α-pinene (37.5%) as its principal component in an oil that contained similar amounts of mono- and sesquiterpenes. The major sesquiterpenes identified in the oil were β-caryophyllene (2.4%), α-humulene (2.2%) and α- and β-eudesmol (8.2% and 8.1%, respectively). Decaspermum humile produced a leaf oil that contained either approximately equal amounts of mono- and sesquiterpenes or had a majority of the latter components. The principal monoterpenes were a-thujene (0.1–13%) and α-pinene (0.2–21%). Other prominent monoterpenes identified were limonene (0.2–8%), myrcene (0.3–10%), β-phellandrene (0.1–5%), linalool (0.3–9%) and terpinen-4-ol (0.3–6%). 1,8-Cineole was usually absent from the oils. The main sesquiterpenes identified in the oils were β-caryophyllene (0.7–5%), aromadendrene (1–6%), viridiflorene (1–7%), δ-cadinene (0.4–14%), bicyclogermacrene (0.2–10%), globulol (1–9%) and in some collections 7-epi-α-selinene (trace-9%).

Results showed that no statistically significant differences were detected among essential oil yields. However, chromatographic analysis of the oils by GC and GC/MS reported that, from a total of 101 volatile components identified, statistically significant differences among concentrations of several volatile components existed. At the qualitative level, oils from La Paca cultivation area (690 m above sea level) showed a volatile profile rich in low molecular weight components and phenolic compounds when compared to those obtained from Torre Blanca cultivation area (30 m above sea level).

(feather dalea, featherplume) was collected from the Jornada Experimental Range in south central New Mexico. Current year's growth was collected from 10 plants, all found within an approximate 50 m radius of the GPS coordinates N32°40.645′ and W106°33.601′ during July 2001. Composite samples of the plants were steam distilled in triplicate, and the composite oil was analyzed using both GC-FID and GC/MS. The volatile composition of plants collected from the same site was also examined using solid-phase microextraction (SPME) with a 100 μm polydimethylsiloxane fiber. Mass spectra and retention indices were used to identify 58 previously described compounds. The retention index and EI mass spectra are provided for one unknown. The most abundant constituents of the oil were α-pinene (31.7%), camphene (8.4%) and limonene (8.1%). In contrast, α-pinene (33.6%), β-pinene (13.2%) and camphene (11.1%) were the most abundant constituents of the SPME samples. This difference in composition may be due to either sampling technique or harvesting time.

Current year's growth was collected from 10 plants, all found within an approximate 50 m radius of the GPS coordinates N32°40.645′ and W106°33.601′ during July 2001. Composite samples of the plants were steam distilled in triplicate, and the composite oil was analyzed using both GC-FID and GC/MS. The volatile composition of plants collected from the same site was also examined using solid-phase microextraction (SPME) with a 100 μm polydimethylsiloxane fiber. Mass spectra and retention indices were used to identify 58 previously described compounds. The retention index and EI mass spectra are provided for one unknown. The most abundant constituents of the oil were α-pinene (31.7%), camphene (8.4%) and limonene (8.1%). In contrast, α-pinene (33.6%), β-pinene (13.2%) and camphene (11.1%) were the most abundant constituents of the SPME samples. This difference in composition may be due to either sampling technique or harvesting time. ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2005.9699022#.Ub8LHdh-Tp-

The main constituents of the inflorescence oils were β-pinene (13.1–19.3%), (E)-nerolidol (7.0–16.1%), piperitone (10.8%, deep pink inflorescences), β-eudesmol (8.4%, white), β-caryophyllene (6.7%, pink) and these of leaf oils—β-eudesmol (12.8%, white flowering plant), borneol (10.7%, pink), piperitone (10.0%, deep pink), caryophyllene oxide (6.4–10.4%), selin-11-en-4a-ol (6.5–7.5%) and spathulenol (6.1%, pink). The amounts of β-pinene decreased and (E)-nerolidol increased in the inflorescence oils with intensity of yarrow fl owers color. The inflorescences with different colored flowers produced markedly higher amounts of sabinene, β-pinene, 1,8-cineole, γ-terpinene, β-caryophyllene, α-humulene and (E)-nerolidol than leaves. The above correlation was identified for mono- and sesquiterpene hydrocarbons. An opposite correlation was determined for spathulenol, caryophyllene oxide, β-eudesmol, selin-11-en-4α-ol and oxygenated sesquiterpenes.

Two chemical groups were characterized in the oils, one which was rich in thymol (46.3–78.1%), and another containing β-caryophyllene (17.3–59.4%) as the major component. In the first group the compounds p-cymene (5.1–7.2%) and β-caryophyllene (4.1–9.2%) have been associated to thymol in six of the analyzed oil samples. On the other hand, the second group showed variable association with (E)-nerolidol (0.7–23.6%), trans-α-bergamotene (0.2–19.3%), α-alaskene (3.4–16.0%), α-pinene (1.2–7.8%), α-hu-mulene (2.6–6.0%), caryophyllene oxide (1.9–6.0%) and linalool (0.9–5.0%), in the other eight oil samples, justifying the field observation concerning the plant scent variability at the same collection site and the chemical composition differentiation observed to L. glandulosa.

Astartea leptophylla contained α-pinene (52.1%), linalool (4.1%), myrtenol (0.7%) and (+)-myrtenal (9.8%). Major components in the Astartea sp. nov. oil were α-pinene (18.1%), linalool (11.3%), myrtenol (6.3%), and (+)-myrtenal (26.2%). GC of the ethanol extracts of the leaves showed a similar monoterpenoid profile to the oils. A higher extract concentration of cyclodecadienes was further evidence for the rearrangement of germacrene D and bicyclogermacrene to cadinene, aromadendrene, elemene and other cyclosesquiterpene derivatives. The hydrosols from both species were also analyzed.

In total, 33 compounds were identified. The oil was characterized by its high content of sesquiterpenes with cyperene (30.9%) being major. The antibacterial activity of oil from tubers of Cyperus rotundus, showed more important activity against Gram-positive bacteria specially Staphylococcus aureus than Gram-negative bacteria. The antimutagenic activity was tested by the “SOS Chromotest” and the “Ames” test. C. rotundus oil acted as an antimutagen against Afl atoxin B1 in both Salmonella strains (TA100 and TA98) and Escherichia coli strain (PQ37) and against nifuroxazide in Escherichia coli strain (PQ37), where its mutagenicity is not expressed. The highest rates of AFB1 mutagenesis inhibition tested by Ames assay, ranged from about 82.56% for TA100 strain to 85.47% for TA98 strain at the same dose of 50 μg AFB1 per plate. Whereas, the mutagenic effect of respectively nifuroxazide and AFB1 (50 μg/assay) were reduced by aproximately 58.19% and 81.67% when tested by the SOS chromotest assay.
