Artemisia Campestris

The chemical composition of the essential oils of aerial parts of Artemisia campestris ssp. campestris, collected from ten different locations in Lithuania is detailed in this paper. The major component in all the oils was caryophyllene oxide (8.5-38.8%), whereas compounds with the caryophyllane skeleton ranged from 10.2 to 44.5%. Other representative constituents were germacrene D (≤15.0%), humulene epoxide II (≤8.1%), β-ylangene (≤7.7%), spathulenol (≤6.8%), β-elemene (≤6.8%), β-caryophyllene (≤6.2%), junenol (≤6.1%) and α- or β-pinene (≤5.5%). Eighty-seven compounds were identified, comprising 73.6-92.3% of the oils. The chemical composition was highly variable depending on the sample location. Toxicity of A. campestris oils was determined using the brine shrimp (Artemia sp.) assay. LC50 values ranging to 20 μg/mL were obtained for three of the oils after 24 hours of exposure. Data of this test revealed that A. campestris ssp. campestris essential oils with dominant caryophyllene oxide are notably toxic.

Germacrene D

Protium ovatum is a Brazilian endemic species widely distributed between the Cerrado and Amazon biomes. Here, we evaluate the chemical composition of the essential oils (EO) of different shoot organs from P. ovatum including stems, petioles, leaves, flowers, ripe and unripe fruits, and investigate their antifungal potential against Sclerotinea sclerotiorum. The EO were obtained by hydrodistillation in a Clevenger-type apparatus and analysed by GC-MS, followed by PCA analysis. The antifungal activity was performed by agar diffusion. Fruits had the highest essential oil contents among the shoot parts. The constituents were found varyingin the different organs: α-Pinene (0.80-18.3%), β-Pinene (0.58-5.17%), Myrcene (0.52-27.3%), Limonene (3.15-59.7%), Caryophyllene E (3.67-16.4%), Germacrene D (6.34-27.4%), and δ-Cadinene (2.29-7.63%). The essential oil from ripe fruit showed the strongest antifungal activity, with the highest Inhibition of Mycelial Growth (IMG) (50.11%) at the lowest concentration assayed (18.75μg.mL-1). This is the first report on the chemical composition of the essential oils from stems, petioles, flowers, and ripe fruits of P. ovatum and their antifungal activity against S. sclerotiorum, making it a potential source of antimicrobial agents

Germacrene D

The aerial parts of Hypericum richeri Vill. subsp. grisebachii (Boiss.) Nyman were collected from two different locations in Croatia and subjected to hydrodistillation. GC/FID and GC/MS analysis of the isolated essential oils revealed 64 compounds representing 94.7% and 98.2% of the total oils. Predominant constituents in both samples were: germacrene D (10.9%; 6.0%), bicyclogermacrene (4.7%; 3.5%), α-pinene (6.8%; 6.9%), β-pinene (8.1%; 5.1%), decanoic acid (4.5%; 6.8%), β-caryophyllene (3.3%; 7.5%), δ-cadinene (7.0%; 4.4%), spathulenol (6.0%; 9.5%) and tetracosane (3.1%; 5.8%). Comparison of both samples revealed similarity in the chemical composition with minor fluctuations of constituent percentages. The chemical profile of Croatian oils was in general similar to those reported for other geographic areas regarding major mono- and sesquiterpene constituents. However, spathulenol, 5-cadinene and bicyclogermacrene were more abundant in Croatian oils. The presence of decanoic acid (4.5%; 6.8%) in Croatian oils was the major difference between acids and fatty acids derivatives. Higher abundance of alkanes (particularly tetracosane and docosane) was also noticed.

Two Populations

The fresh aerial parts of essential oils and headspace volatiles of two populations of Athamanta turbith ssp. haynaldii were analyzed in detail by GC and GC/MS analyses. In headspace samples, 32 compounds were identified, representing 98.4% and 98.8% of the total volatiles and were dominated by hydrocarbon sesquiterpenes, representing over 60% of both. Germacrene D was the major component, followed by terpinolene and myristicin. The essential oils of A. turbith consisted mainly of phenylpropene compounds with myristicin being the major compound. Fifty two compounds were identified in the oil isolated from Perućac and 57 from Kremna, accounting for 99.0% and 99.6% of total detectable components, with myristicin (52.3% and 50.8%, respectively) being the major component. In both samples, myristicin, germacrene D and δ-cadinene make up over 78% of the total oil composition. Antioxidant activity was measured using four different assays: DPPH, ABTS, CUPRAC and TRP method. It was found that the essential oil showed low antioxidant capacities compared with standard antioxidant compounds.

First Time

The in vitro antimalarial, trypanocidal and leishmanicidal activities and the chemical composition of Ambrosia tenuifolia and A. scabra essential oils were investigated. The oils, obtained by hydrodistillation of the aerial parts, showed significant antimalarial activity against the chloroquine sensitive (F32) and the chloroquine resistant (W2) strains of Plasmodium falciparum with 50% inhibitory concentration (IC50) values ranged from 2.8 to 7 μg/mL. Against Trypanosoma cruzi epimastigotes, only A. tenuifolia exerted slight activity (IC50 = 59.7 μg/mL). None of the essential oils showed toxicity towards Leishmania mexicana. Cytotoxicity for murine T-lymphocytes was compared with the parasiticidal activity by using the selectivity index (SI) ratio. The chemical composition of A. tenuifolia and A. scabra essential oils was analyzed by GC-FID-MS. Thirty-eight and twenty-four compounds were identified in A. tenuifolia and A. scabra, respectively. The major constituents of A. tenuifolia oil were germacrene D (22.9%) and bicyclogermacrene (14.2%), while the oil of A. scabra contained limonene (22.0%), caryophyllene oxide (13.8%) and ( E)-caryophyllene (13.5%). This is the first time that the antiprotozoal activity of both oils and the chemical composition of A. scabra essential oil have been reported.

The chemical composition of the essential oils obtained from aerial parts of Nepeta alatavica Lipsky, N. nuda L., and N. olgae Regel (Lamiaceae), growing wild in Central Asia (Tajikistan and Uzbekistan), were analyzed by GLC and GLC-MS. The main constituents of the essential oil from N. nuda were 1,8-cineole (24.6%), 4a-α,7-β,7a-α-nepetalactone (21.0%), germacrene D (13.5%), and β-caryophyllene (12.7%), whereas those of N. alatavica were thymol (48.5%), verbenone (7.7%), and carvacrol (7.5%). In the essential oil of N. olgae the most abundant compounds were acetylcyclohexene (31.5%), 4-tridecyne (13.2%), 2-methyl cyclopentanone (6.8%) and 1,8-cineole (6.0%). The potential antioxidant activity of these essential oils was studied by using DPPH, ABTS and FRAP assays. The essential oil of N. alatavica showed the highest in vitro free radical scavenging activity, probably due to its high thymol and carvacrol content.

Hypericum Species

The chemical composition of the essential oils obtained by hydrodistillation from the aerial parts of the Tunisian Hypericum perforatum and H. ericoides ssp. roberti was elucidated by a combination of GC and GC-MS analyses. The main constituents of the oil of H. perforatum were α-pinene (11.8%), α-ylangene (10.4%), germacrene-D (9.5%), n-octane (6.5%) and α-selinene (5.9%). The oil of H. ericoides ssp. roberti exhibited a higher amount of aliphatic and branched hydrocarbons and the main constituents were n-octane (29.1%), α-pinene (10.9%), pulegone (7.7%) and acetophenone (7%). Both qualitative and quantitative differences were observed between the studied oils. This chemical variability seems likely to result from the genetic variability, since samples of both species were collected at the same location and processed under the same conditions.

AbstractThis study was aimed to determine the chemical composition of essential oils obtained from aerial parts of Thymus algeriensis Boiss. & Reut. and Marrubium vulgare L. collected in the Aures region of Algeria. Essential oils were extracted by steam distillation method and analyzed using GC-MS and GC-FID techniques. Thirty-five (35) and twenty-nine (29) components were identified respectively in T. algeriensis and M. vulgare essential oils to represent respectively 94.8% and 75.7% of the total oil composition. The main compounds of T. algeriensis oil were germacrene D (29.6%), β-caryophyllene (11.0%), E-β-farnesene (7.8%), bicyclogermacrene (4.4%) and δ-cadinene (4.0%), while, β-bisaboene (36.3%), β-caryophyllene (7.8%), phytol (6.2%), nonacosane (4.0%) and heptacosane (3.3%) were the main components of M. vulgare oil. The richness of these two oils in germacrene D and β-bisaboene respectively could suggest a new bioactivity.
