Chemical composition of essential oils from Bambusa vulgaris Leaf (Fresh and Dried) Schrad. Ex J.C. Wendl. [Poaceae] obtained in Nigeria

Essential oil is a hydrophobic concentrated liquid which contains volatile aroma compounds from plants. Bambusa vulgaris grows widely in the tropical and subtropical regions and has been reported to have different ethnomedicinal values such as antimalaria and antioxidant. It is also known to be an ornamental plant. The essential oil was extracted from both the fresh and dried leaves of Bambusa vulgaris by hydrodistillation method using a Clevenger apparatus. The chemical constituents of the essential oils were characterized using gas chromatography and gas chromatography-mass spectrometry. The essential oils obtained are colourless with an herbal odour giving a yield of 0.64 w/w for the fresh sample and 1.08 w/w for the dried sample. A total of thirty-nine (39) compounds were identified from the essential oils of both samples. The major constituents in the fresh leaves were 3-aminodibenzofuran (19.2%), ?-ocimene (11.1%), undecane (9.6%), tridecane (8.6%), [3,2-b] pyridin-6-octahydropyrano (7.1%), 2-mono laurin (6.9%) and vinyl decanoate (5.9%). Prominent compounds of the essential oil in the dried leaves were chlorophenoxymethylenimino sulfur pentafluoride (74.5%) and 2,2,6,6-tetramethyl-3,5-heptanedione (17.3%). Undecane, tridecane, hexadecane and octadecane were found both in the fresh and dried leaves. The chemical constituents of the essential oils from Nigeria Bambusa vulgaris were reported in this study for the first time to the best our knowledge and this could be useful in aromatherapy.

Here we report for the first time hydrodistillation of leaf essential oils from Phebalium squamulosum subsp. verrucosum, P. glandulosum subsp. eglandulosum, P. glandulosum subsp. nitidum and P. glandulosum subsp. angustifolium (Rutaceae: Boronieae). Essential oils were analysed using gas-chromatography/mass spectrometry (GC-MS) and nuclear magnetic resonance spectroscopy (NMR). With the exception of P. glandulosum subsp. angustifolium, all taxa yielded essential oils in relatively high amounts (1–3%, w/w) made up predominantly of 2,6-dimethyloct-7-en-4-one (dihydrotagetone). The essential oil from P. squamulosum subsp. verrucosum contains either (+)-dihydrotagetone ( ee 94–100%) or (-)-dihydrotagetone ( ee 17–18%). Taxonomically, these results support the proposal that P. squamulosum subsp. verrucosum may be specifically misplaced, phytochemically resembling the P. glandulosum complex. Similarly, P. glandulosum subsp. angustifolium phytochemically resembles P. distans or P. longifolium and also appears to be assigned incorrectly to the P. glandulosum group.

Leaf Oil

Greenwayodendron suaveolens (Engl.& Diels) is a tree that grows with a straight regular trunk, dark bark as well as a small crown with horizontal branches. Greenwayodendron suaveolens bark and roots are used for vermifuges, and as an aphrodisiac while the leaf is used as a pain-killer, and as a cure for dysenteries and fevers. The leaves of Greenwayodenron Suaveolens were collected at the biology farm of Olabisi Onabanjo University Ago-Iwoye Ogun State and extracted by hydro-distillation using Clevenger apparatus. The qualitative and quantitative analyses of the wet and dried leaf essential oil were performed using Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS). From the GC-MS analysis, a total of twenty-eight (28) compounds (98.01 %) were identified in the fresh sample, while the dried sample had fourteen (14) compounds representing 99.90 % of the constituents. The major components of Greenwayodendron Suaveolens essential oils were: terpenes 73.75 % and 67.91 %, oxygenated terpenes; 7.04 % and 9.24 % , hydrocarbons; 6.37 % and 24.89 % ,alcohols; 6.75 % and 2.81 % in the fresh and dried leaf oil samples while heterocyclic compounds 13.02 5 and esters 1.48 % were present only in the fresh leaf oil samples. The high percentage of terpenes in both oil samples could justify the traditional use of the plants in treating pains, headaches and inflammations. This study presents the results of the essential oil composition of the fresh and dried leaf samples of Greenwayodendron suavolens which will be useful in research.

The essential oils from two members of the Asteraceae ( Acanthospermum hispidum DC. aerial parts, and leaves of Tithonia diversifolia (Hemsley) A. Gray), growing wild in Osun State, Nigeria, have been characterised by combined gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analyses. Twenty-nine components have been fully identified and grouped into monoterpene hydrocarbons (22.2%), oxygenated monoterpenes (4.6%), sesquiterpenes hydrocarbons (58.2%) and oxygenated sesquiterpenes (10.8%) in A. hispidum. The main constituents of the oil were β-caryophyllene (28.0%), α-pinene (15.9%) and bicyclogermacrene (11.0%) among the hydrocarbon compounds, and bisabolol (8.9%) and carvacrol methyl ether (4.1%) among the oxygenated components. Tithonia diversifolia essential oil comprised seventeen components and was characterised by a predominant content of monoterpene hydrocarbons (87.9%), cis-β-ocimene (43.7%), α-pinene (28.6%) and limonene (12.0%) being the main compounds. Sesquiterpenes represented ca. 10% oil, as sum of hydrocarbons and oxygenated components. A new chemotype is established for T. diversifolia, while the Nigerian A. hispidum is being reported for the first time as a new source of essential oil with some distinction in composition from those of other sources.

Abstract The objective of current study was to determine the chemical constituents and fumigant toxicity of essential oil isolated by hydro-distillation from dry fruit of bitter fennel (Foeniculum vulgare Miller). The chemical composition of the essential oil was assessed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Constituents of the oil were determined as α-pinene (1.6%) and limonene (3.3%), fenchone (27.3%), estragol (3.9%), and (E)-anethole (61.1%). The fumigant toxicity of the essential oil was tested on larvae of the stored product insect Trogoderma granarium Everts. The mortality of larvae was tested at different concentrations ranging from 31.2 to 531.2 μl/l air and at different exposure times (24 and 48 h). Probit analysis showed that LC50 and LC90 following a 48 h-exposure period for essential oil were 38.4 and 84.6 μl/l, respectively. These results showed that the essential oil from F. vulgare may be applicable to the management of populations of stored-product insects.

The aim of this study was to determine the chemical variability of wormwood extracts as affected by the growing region. Antioxidant and antimicrobial activities were also investigated. The essential oil composition variability ofA. absinthiumL. aerial parts collected from four different Tunisian regions was assessed by gas chromatography (GC/FID) and by gas chromatography mass spectrometry (GC/MS). In addition, total polyphenols, flavonoids, and condensed tannins as well as antioxidant, antibacterial, and antifungal activities of methanolic extract and essential oils were undertaken. Chromatographic analysis of wormwood essential oils showed the predominance of monoterpene hydrocarbons represented mainly by chamazulene. RP-HPLC analysis of wormwood methanolic extract revealed the predominance of phenolic acids. Antiradical activity was region-dependant and the methanolic extract of Bou Salem region has the strongest activity (CI50=9.38±0.82 µg/mL). Concerning the reducing power, the methanolic extract of Bou Salem, Jérissa, and Boukornine regions was more active than the positive control. Obtained results of antimicrobial activities showed that wormwood essential oil is endowed with important antibacterial activity which was strongly related to the organoleptic quality of oil which appeared strongly region-dependant.A. absinthiumL. EOs investigated are quite interesting from a pharmaceutical standpoint because of their biological activities.

First Time

Chemical compositions of plants are affected by the initial nutrient contents in the soil and climatic conditions; thus, we analyzed for the first time the effects of soil and leaf nutrients on the compositions of the essential oils (EOs) of Siparuna muricata in four different localities in Ecuador. EOs were obtained by hydrodistillation and analyzed by gas chromatography/mass spectrometry (GC/MS) and a gas chromatography/flame ionization detector (GC/FID). Enantiomeric distribution by GC/MS was determined, modifying the enantiomeric separation of β-pinene, limonene, δ-elemene, β-bourbonene, cis-cadina-1 (6), 4-diene and atractylone. A total of 44 compounds were identified. The most representative for L1 were guaiol, atractylone and 4-diene; for L2, cis-cadina-1(6),4-diene and myrcene; for L3, atractylone, myrcene and germacrene B; and finally, L4 germacrene B, myrcene and cis-cadina-1(6),4-diene. Correlations between soil- leaf chemical elements such as Al, Ca, Fe, Mg, Mn, N and Si in the different localities were significant with chemical composition of the essential oil of Siparuna muricata; however, correlations between soil and leaf K, P, and Na were not significant. Cluster and NMDS analysis showed high dissimilarity values of secondary metabolites between four localities related with changes in soil- leaf nutrients. Thus, the SIMPER routine revealed that not all secondary metabolites contribute equally to establishing the differences in the four localities, and the largest contributions are due to differences in guaiol, cis-cadina-1(6),4-diene, atractylone and germacrene. Our investigation showed for the first time the influences of altitude and soil- leaf chemical elements in the chemical composition of the EOs of S. muricata.

Protium aracouchini (Aubl.) Marchand [sin Icica aracouchini Aubl.], which occurs in the Adolpho Ducke Forest Reserve, in the Brazilian Amazon, was evaluated for the presence of galls, for resin exudation and the composition of the essential oils from the aerial parts and the resin. The experiment to stimulate the exudation of resin from the trunk was conducted using a 2-chloroethylphosphonic acid solution. The resin produced after 40 days and the aerial parts had their essential oils extracted in a Clevenger apparatus and the volatile chemical constituents were analyzed using GC/MS. The non-oxygenated sesquiterpenes α-copaene (21.15%) and α-gurjunene (13.69%), in addition to the oxygenated sesquiterpene spathulenol (10.32%), were detected as the majority constituents of the essential oil of the leaves, and a concentration similar to that of α-gurjunene was found in the branches (13.28%). The resin essential oil showed a high concentration of hydrocarbon monoterpenes (76.49%) with a predominance of α-pinene (17.57%) and limonene (46.11%). Four gall morphotypes were found associated with this species. The present study reports for the first time information on the volatile constituents and the resinous potential of P. aracouchini, and registers the morphotypes of the galls that help in the taxonomy of the species.
