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.

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.

Main Components

The essential oils of four Teucrium species were studied and 131 components, in all, were identified. All oils were rich in sesquiterpenes (50.0-61.9%). Caryophyllene and caryophyllene oxide were the main components of Teucrium arduini; germacrene D, δ-cadinene and γ-cadinene predominated in Teucrium maghrebinum. Carvacrol and caryophyllene predominated in Teucrium polium ssp. capitatum, while carvacrol, caryophyllene oxide and caryophyllene were the most abundant components in Teucrium montbretii ssp. heliotropiifolium. The germination of radish and garden cress was less sensitive to the four essential oils. The radicle elongation, above all, of radish was significantly inhibited by all oils, in particular by the essential oil of T. arduini, at the highest doses tested. Among the main components of the oils, monoterpenes resulted the more active compounds.

Baccharis is an Asteraceae genus of flowering plants, which has about 340 to 400 species, ranging from the Southern United States to the Southern extreme of Argentina and Chile through Central America and the Caribbean regions. The species Baccharis trinervis is a native shrub from Mexico, Central America and throughout South America. In Costa Rica, this species is commonly known as alcotán and the fresh leaves are used as a poultice on wounds and ulcers. The objective of the present research was to characterize the chemical composition of seven hydrodistilled essential oils of diverse morphological parts of B. trinervis. For this, samples were obtained from three locations in Costa Rica and standard laboratory analyses were followed. The essential oils were analyzed by capillary gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) using the retention indices on a 5 % phenyl/dimethylpolysiloxane fused silica column in addition to mass spectral fragmentation patterns, which allowed the identification of 268 compounds. The essential oils consisted mainly of terpenoids (92.3 to 97.8 %). The major constituents from the leaf oils were caryophyllene oxide (0.1-22.5 %), viridiflorol (8.8-21.0 %), germacrene D (0.5-19.1 %), germacrene B (0.2-16.0 %), β-caryophyllene (3.5-9.1 %), spathulenol (0.1-8.3 %), δ-3-carene (2.0-6.8 %), and α-pinene (2.5-5.9 %). The flower oil consisted mainly of globulol (0-24 %), β-caryophyllene (9.5-17.1 %), cis-muurola-4(14), 5-diene (traces-13.7 %), germacrene D (4.3-9.9 %), bicyclogermacrene (5.9-8.3 %), ar-curcumene (0-8.0 %), spathulenol (4.3-4.8 %), caryophyllene oxide (3.1-4.7 %), and viridiflorol (0.3-4.7 %). The major components of the branch oil were germacrene B (1.4-18.7 %), germacrene D (14.7-15.6 %), β-caryophyllene (10.1-12.4 %), viridiflorol (0-11.5 %), globulol (0.6-11.3 %), δ-3-carene (4.1-8.1 %), β-phellandrene (1.5-6.5 %), and bicyclogermacrene (3.6-4.9 %). The essential oil composition differed markedly from that of previously studied oils of plants growing in Brazil, which contain two characteristic stereoisomeric methyl dec-2-en-4,6-diynoate compounds not detected in this study. This is the first report about the chemical composition of the essential oils obtained from this species growing wild in Costa Rica.
