Moss Species

Two peat moss species, frequent both in the mainland Portugal and in the Azores archipelago, were evaluated for essential oil composition and establishment under in vitro culture. Sphagnum auriculatum and Sphagnum subnitens essential oils were isolated by hydrodistillation and analysed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS). The essential oil of S. auriculatum was dominated by an as yet unidentified sesquiterpene, whereas zierene was the main component of S. subnitens essential oil. The in vitro cultures were successfully established for future studies of their chemical profile. The components present in essential oils obtained from S. auriculatum and S. subnitens together with morphological traits could be used to support the taxonomy of this plant group.

The principal aim of this study was to analyze the chemical composition and qualitative and quantitative variability of essential oils obtained from seven naturally grown populations of thePinus peuceGrisebach, Pinaceae in Kosovo. Plant materials were collected from three populations in the Sharri National Park and from four other populations in the Bjeshkët e Nemuna National Park, in Kosovo. Essential oils were obtained by steam distillation and analyzed by GC-FID (Gas Chromatography-Flame Ionization Detection) and GC-MS (Gas Chromatography-Mass Spectrometry). The results showed that the yield of essential oils (v/wdry weight) varied depending on the origin of population and the plant organs and ranged from 0.7 to 3.3%. In total, 51 compounds were identified. The main compounds wereα-pinene (needles: 21.6–34.9%; twigs: 11.0–24%),β-phellandrene (needles: 4.1–27.7; twigs: 29.0–49.8%), andβ-pinene (needles: 10.0–16.1; twigs: 6.9–20.7%). HCA (Hierarchical Cluster Analysis) and PCA (Principal Component Analyses) were used to assess geographical variations in essential oil composition. Statistical analysis showed that the analyzed populations are grouped in three main clusters which seem to reflect microclimatic conditions on the chemical composition of the essential oils.

Essential oils obtained by hydrodistillation of leaves of two Nigerian species were analyzed for their constituents by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The leaf oil of Ficus benjamina L. (Moraceae), collected during the day, contained high contents of α-pinene (13.9%), abietadiene (9.7%), cis-α-bisabolene (8.2%) and germacrene-D-4-ol (8.4%), while the night sample was dominated by germacrene-D-4-ol (31.5%), 1,10-di- epi-cubenol (8.8%) and hexahydrofarnesylacetone (8.3%). This could be a possible indication of differences in emissions of volatiles by F. benjamina during the day and night. The main compounds of Irvingia barteri Hook. f. (Irvingiaceae) were β-caryophyllene (17.0%), (E)-α-ionone (10.0%), geranial (7.6%), (E)-β-ionone (6.6%) and β-gurjunene (5.1%).

The goal of this study was to investigate the essential oil compositions of different parts (stem, leaf, flower and mixture) of Lavandula x intermedia in Bismil-Diyarbakır,Turkey. The chemical composition of essential oils obtained by hydrodistillation from fresh Lavandin samples were analyzed using gas chromatography-mass spectrometry (GC/MS). The results indicate the major components of the studied parts of lavandin was; linalool (24.97-2.52-43.86-39.43 %), linalyl acetate (3.,4-0.29-9.37-15.76 %), eucalyptol (33.81-43.81-18.47-12.08 %), camphor (13.12-15.91-8.72-9.21 %), endo-borneol (2.03-5.18-0.68-1.24 %) and alpha-terpineol (2.84-2.47-1.28-3.86 %) in essential oils of stem, leaf, flower and mixture parts of fresh lavandin respectively. It was understood that linalool and linalyl acetate level were the highest in flower and mix parts while eucalyptol, camphor and endo-borneol levels were the highest in stem and leaf parts of the plant.

The essential oil composition from the aerial parts of three Anacardiaceae growing in Bahía Blanca, Argentina was studied by gas chromatography and gas chromatography-mass spectrometry. The essential oils of S. longifolia and S. fasciculata have been studied for the first time. The major constituents were α-pinene (46.5%), β-pinene (15.1%) and α-phellandrene (10.1%) for S. longifolia and limonene (10.9%), β-phellandrene (6.16%) and α-phellandrene (5.6%) for S. fasciculata. The major components of the essential oil of S. areira were limonene (28.6%), α-phellandrene (10.1%), sabinene (9.2%) and camphene (9.2%) differing from the literature data. The essential oils from S. areira and S. longifolia exhibited a high biotoxicity in a brine shrimp assay with Artemia persimilis.

The composition of essential oils obtained from leaves ofAcorus calamusgrowing wild in 19 different locations was analysed by gas chromatography and gas chromatography–mass spectrometry. In total, 84 constituents have been identified, representing at least 86% of the total essential oil. The essential oils were dominated by the presence of phenolic compounds: (Z)-asarone (15.7–25.5%) and (Z)-methyl isoeugenol (2.0–4.9%). Other identified major components were (E)-caryophyllene, α-humulene, germacrene, linalool, camphor and isoborneol. All oils were found to have a similar composition. However, a hierarchical cluster analysis of the quantitative data revealed significant differences between some accessions. Minimal inhibitory concentrations (MIC) of four selected leaf essential oils were determined by a screening test with the broth dilution method. Of the 17 species of fungi, bacteria and yeasts tested,Mycobacteriumssp. andBacillus subtiliswere most susceptible to essential oils. Oils displayed low anti-fungal activity and their inhibitory activity was lower than the standard antibiotics. Oils differed in their activities against the various microorganisms tested.

AbstractCryptocarya species are mainly distributed in Africa, Asia, Australia and South America, widely used in traditional medicines for the treatment of skin infections and diarrhea. The present investigation reports on the extraction by hydrodistillation and the chemical composition of three Cryptocarya species (Cryptocarya impressa, Cryptocarya infectoria, and Cryptocarya rugulosa) essential oils from Malaysia. The chemical composition of these essential oils was fully characterized by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). A total of 51 components were identified in C. impressa, C. infectoria, and C. rugulosa essential oils representing 91.6, 91.4, and 83.0% of the total oil, respectively. The high percentages of α-cadinol (40.7%) and 1,10-di-epi-cubenol (13.4%) were found in C. impressa oil. β-Caryophyllene (25.4%) and bicyclogermacrene (15.2%) were predominate in C. infectoria oil. While in C. rugulosa oil, bicyclogermacrene (15.6%), δ-cadinene (13.8%), and α-copaene (12.3%) were predominate. To the best of our knowledge, there is no report on the essential oil composition of these three species.

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.
