ABSTRACT Composition and antimicrobial activity of root, leaf, stem, flower and fruit essential oils from cultivated Pastinaca sativa subsp. sativa, and its two wild-growing relatives P. sativa subsp. urens and P. hirsuta (Apiaceae) were investigated. Twenty-nine hydrodistilled essential oils of plants from different localities and/or years were analysed by GC-FID and GC/MS. Dominant in root oils was myristicin (P. sativa) or apiole (P. hirsuta), in leaf and stem oils myristicin (cultivated plants) or γ-palmitolactone (wild-growing plants) and in flower and fruit oils aliphatic esters. Multivariate statistics (PCA, nMDS, UPGMA clustering) generally revealed separation of oils of investigated Pastinaca taxa and demonstrated their chemosystematic significance. One oil per each organ of all three plants (fifteen in total) was tested using microdilution method for activity against Candida tropicalis, C. parapsilosis, C. krusei, C. glabrata, C. albicans, Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Escherichia coli, Salmonella Typhimurium and Enterobacter cloacae; MIC = 0.25–8 mg/mL, MBC(MFC) = 0.5–16 mg/mL.

ABSTRACT The genus Eucalyptus belonging to the Myrtaceae family, consists of tall, evergreen trees with leathery leaves. They are indigenous to Australia and contain about 900 species and subspecies. One important use is production of essential oils, which are valuable in both medicinal and pharmaceutical industries. There are about 62 species of Eucalyptus naturalized to Cyprus including E. camaldulensis and E. torquata. The essential oil constituents of leaves of these two species of Eucalyptus collected from Northern Cyprus were isolated by hydro-distillation and analyzed by GC and GC/MS, simultaneously. E. camaldulensis oil yield was higher (2.4%), and major compounds identified were α-phellandrene (10.3%) and β-phellandrene (30.6%), respectively. These compounds were followed by p-cymene (8.2%), bicyclogermacrene (6.1%) and spathulenol (9.3%). On the other hand, E. torquata oil yield was relatively lower (1.6%), with major compounds being α-pinene (18.6%), 1,8-cineole (18.8%), β-eudesmol (10.3%) and torquatone (29.2%).

ABSTRACT The genera Nigella and Garidella are two members of the Nigelleae tribe. Among all the taxa of the tribe, black cumin (Nigella sativa L.) is one of the most important plants concerning economic and medicinal uses. In this study, volatiles were analyzed in detail to elucidate the phytochemical profiles and to understand the taxonomic patterns of secondary metabolites for 19 taxa of Nigella and Garidella collected from Turkey and the neighboring countries. Volatiles were analyzed by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC/MS) using different polarity columns. Seventeen Nigella and two Garidella taxa were investigated, with 130 volatile oil components characterized. Structural similarities of the compounds were clustered by a machine learning algorithm using the molecular fingerprinting method. Our results depict that the phytochemicals produced by Nigelleae can be classified independently of their chemical families and significantly contribute to genera delimitation by their structural distances.

ABSTRACT The essential oils from Cantinoa carpinifolia (Benth.) and Lippia origanoides (Kunth.) were obtained by hydrodistillation. The constituents were determined by GC-MS and GC-FID. The antioxidant activities were evaluated by the ABTS, DPPH and hydroxyl radicals, phosphomolybdenum complex, reducing power, β-carotene/linoleic acid and the TBARS methods. Analysis of variance and the Scott–Knott test of the means at 5% were performed. The principal constituents in the essential oil from C.carpinifolia were α-thujone (32.15%) and β-thujone (22.22%), whereas carvacrol (41.51%), p-cymene (18.36%) and γ-terpinene (17.03%) were obtained from L.origanoides. The respective IC50 for the essential oils from C. carpinifolia and L.origanoides in the ABTS tests were >1000 and 110 µg mL−1; DPPH (110 and >1000 µg mL−1), hydroxyl (636 and 484 µg mL−1), β-carotene (>2000 and 215 µg mL−1) and TBARS (778 and 527µg mL−1). The L. origanoides essential oil was the most effective antioxidant.

ABSTRACT The objective of this study was to evaluate the chemical profile and acaricidal activity against the mite Suidasia pontifica of the essential oils from leaves of Piper marginatum Jacq and aerial parts (branches, leaves, and inflorescences) of Piper callosum Ruiz & Pav. From the aerial parts (branches, leaves and inflorescences) of P. callosum, three different essential oils were extracted with variations in the contents of their chemical constituents. The major compounds in the essential oil of P. marginatum were δ-3-carene and (E)-β-ocimene, while safrole was the predominant compound in the essential oils of P. callosum. Concentrations of 4 μL/L of the essential oil of P. marginatum and 2 μL/L of the essential oil of P. callosum killed all the mites tested after 72 h of exposure. The 50% lethal concentration ranged from 1.19 to 2.16 µl/L air for P. marginatum and from 1.22 to 3.44 µl/L air for P. callosum.

ABSTRACT This work aimed to obtain and investigate the properties and composition of extracts from flowers of Acacia mearnsii; this tree is widely cultivated because the bark is used as a raw material for various industry segments, but the flowers are not yet explored. The essential oil was evaluated by GC/FID, GC/MS, and GC/O. The antioxidant activity (DPPH and phosphomolybdenum methods) and chemical composition were investigated for a water-soluble extract, a by-product of the extraction process. 85.8% of the compounds present in the essential oil were identified, 8-heptadecene being the major compound. The main scents detected by the olfactory analysis were roast nutty, coffee, sweet, and floral. The water-soluble extract showed antioxidant activity that may be related to phenolic compounds. Results obtained from the LC-qTOF/MS analysis have shown that 25 likely flavonoids, such as naringenin, myricetin, quercetin, and rutin are present in the extract.

ABSTRACT Zinnia grandiflora (Asteraceae) is used to alleviate several painful disorders. The effects of an essential oil prepared by hydrodistillation from Z. grandiflora (EOZ) and its major compound on neuropathic pain, allodynia, and inflammation in mice were assessed. Headspace-solid phase microextraction analysis of an aqueous extract was also carried out. GC-MS analyses of all volatiles revealed that germacrene D (13.24%) and desmethylisoencecalin (DME) (13.24%) were the most abundant compounds. EOZ was effective in reducing inflammation and allodynia in mice. EOZ (300 mg/paw) reverted tactile allodynia more effectively than gabapentin (100 μg/paw). DME (0.1‒10 µg/paw) responses in the carrageenan model were concentration-dependent; the maximum effect was observed at 10 µg/paw, like that of diclofenac (30 μg/paw). In the spinal nerve ligation model, DME (0.1‒10 μg/paw) exerted a concentration-dependent anti-allodynic action; its effect was better than that of gabapentin. A method to quantify zinagrandinolide E in the crude drug was developed and validated.

ABSTRACT In this work, the essential oils (EOs) from leaves and flowers of Rhododendron spinuliferum and Rhododendron spiciferum were extracted by hydrodistillation, chemical compositions of EOs were analyzed by GC-MS and GC-FID. For R. spinuliferum and R. spiciferum, α- and β-pinene were common major compounds. It provided an opportunity to test the potential synergistic effect of α- and β-pinene among EOs. Firstly, four EOs and two major compounds (α- and β-pinene) exhibited fumigant, contact and repellent activities to three stored-product insects. To the red flour beetle, leaves of both species exhibited stronger contact toxicity than flowers did. This trend was diverse to the booklouse. Furthermore, binary mixture bioassays of α- and β-pinene were performed following natural proportions. Results of multiple linear regression showed that α-pinene, trans-β-farnesene and bornyl acetate were responsible for the contact toxicity to the red flour beetle and booklouse with diverse contribution.

ABSTRACT The aims of this study were to evaluate the anti-inflammatory activity and the possible anti-inflammatory mechanisms of Anastatica hierochuntica essential oil (EOAH). The essential oils were obtained by hydrodistillation of the aerial parts of the plant, and analyzed using gas chromatography and mass spectrometry (GC/MS). Their anti-inflammatory activity was evaluated using classical model of inflammation (carrageenan-induced paw edema and peritonitis). Nitric oxide radical-scavenging activity and lipid peroxidation were determined to assess the antioxidant activity of the essential oil. The EOAH mainly comprised Cuminaldehyde (33.8%), trans-β-Caryophyllene (32.5%), and Linalool (8.2%). EOAH significantly reduced edema, peritonitis, myeloperoxidase activity, and NOx-peritoneal lavage concentration induced by carrageenan. In addition, nitric oxide radical generated from sodium nitroprusside was significantly inhibited by the essential oil. Furthermore, EOAH was able to prevent Fe+2- or Fe+2 plus H2O2-induced lipid peroxidation. In conclusion, the EOAH exerts anti-inflammatory activity that could be related to its antioxidant capacity.

ABSTRACT The chemical composition and antioxidant activity of the essential oil from the leaves of Ambrosia arborescens Miller grown in the Peruvian Andes were studied. One hundred and thirteen compounds were identified, which represents 94.7% of the total composition of the essential oil. Sesquiterpene hydrocarbons and oxygenated monoterpenes were the most represented classes of volatiles with 43.8% and 22.4%, respectively. The main constituents of the essential oil were β-acoradiene (15.3%) and chrysanthenone (11.3%). Antioxidant activities were examined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP) and determination of lipid peroxidation in brain rat homogenates (LPO) assays. The essential oil had a free radical scavenging effect, and it displayed ferric reducing capacity and antioxidant activity by inhibition of LPO.
