ABSTRACT Main chemical compositions of essential oil (EO) from Litsea cubeba fruit collected in Kon Tum Province of Vietnam were geranial (32.0%), neral (24.3%), citronellal (14.2%), and limonene (10.1%). Twenty-four compounds of the EO were identified and compared with those from EOs previously reported in India, China, and Malaysia. Minimal inhibitory and bactericidal concentrations (MIC and MBC) indicated that the EO induced high levels of growth inhibition and moderate bactericidal activity against seven test Helicobacter pylori strains, including six strains resistant to one to four antibiotics, azithromycin, erythromycin, levofloxacin, and metronidazole. The bacterial biofilm formation was significantly suppressed by the EO at 1/2 and 3/4×MIC. The EO also exerts inhibitory activity against H. pylori-urease and convert a spiral form of H. pylori into a coccoid form. Fruit EO inhibits bacterial growth via both contact and fumigant action.

ABSTRACT Artemisia kanashiroi, is an important aromatic medicinal plant that is endemic to China. In the study, the chemical components of essential oil (EO) of A. kanashiroi obtained from different regions in China were analyzed. The results indicated that oxygenated monoterpenes are the predominant components of all EOs, and the major components were 1,8-cineole, camphor, terpine-4-ol, α-terpineol and spathulenol. The chemical composition of EOs exhibited ecological diversity driven by geographical factors. Furthermore, we evaluated the in vitro biological activities of the EOs, including their antioxidant and antibacterial activities. All of the EOs exhibited moderate to potent, broad-spectrum antibacterial and antifungal activities targeting both Gram-positive and Gram-negative bacteria. However, none of the EOs showed significant activity against the tested fungal strains. The antioxidant activity of the EOs was evaluated based on their scavenging activity against 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radicals, and all of the EOs showed significant concentration-dependent DPPH free radical scavenging activity.

ABSTRACT This study aimed to describe the chemical composition of the essential oil (EO) of stems, leaves and flowers of A. maritima collected from Turkey, and verify its antimicrobial and antioxidant properties. The EO was analyzed by GC-FID and GC-MS. Fifty-nine compounds representing to 98.1% of the EO were identified. The antimicrobial activities were determined against seven bacteria and two yeast species by using disc diffusion and MIC techniques. According to the results, it was observed that there was no effect of the EO against Gram-positive bacteria. The EO showed a low effect (8–9 mm) against Gram-negative bacteria, but the EO had a high effect (20–22 mm) against the tested fungi. In addition, according to the MIC test results, the EO presented effects against C. krusei, C. parapsilosis at a concentration of 50 µl/ml. The antioxidant activity of the EO was determined as IC50 = 31.9 µl/mL.

ABSTRACT The post-harvest stage of crops aims to minimize losses occuring during storage and commercialization. Drying process are some of the most used methods to minimize those losses. This work aimed at studying the drying kinetics of cinnamon (Cinnamomum zeylanicum), subject to two different drying conditions, one of which in an experimental fixed-bed dryer relying on an ambient air and speed of 0.5 m s−1, and the other with a forced air circulation oven at different temperatures (313.5, 323.15, 333.15 and 343.15 °K). The time required to reach the moisture equilibrium contents was 1.42, 3.0, 6.41, 14.0 and 21 h for drying temperatures of 343.15, 333.15, 323.15, 313.5 and 307.95 ºK, respectively. The Arrhenius equation described the diffusivity’s dependence on temperature, defining the activation energy of 64.77 kJ mol−1. The essential oils of the samples were analyzed through gas chromatography, which identified 23 individual compounds being eugenol the most abundant.

ABSTRACT The leaf oil from Baccharis punctulata D.C. specimens from Argentina, analyzed by GC and GC/MS during a one-year phenological cycle, showed important changes. In spring and summer, during the stem and floral bud development, the percentages of amorpha-4,7(11)-diene, amorpha-4-en-7-ol, amorpha-4,7-diene-11-ol and amorpha-4,7(11)-dien-8-one increased, while the percentage of verboccidentafuran decreased (c.a. 50% to 10%). The percentage of the guaiane alismol, which was negligible in other months, also increased (19.1–24.8 %). Alismol structure was spectroscopically established. Interesting, when buds opened, alismol percentage fell, so pre- and full-flowering oil composition resulted very different. Germacra-1(10),5-dien-4α-ol (16.7–23.0 %), verboccidentafuran (16.1–18.4%) and elemane-type sesquiterpenes were main components at flowering. Germacra-1(10),5-dien-4α-ol may have the adequate configuration and conformation to be biosynthetically related to alismol. Finally, germacra-1(10),5-dien-4α-ol and elemene derivative percentages decreased. Verboccidentafuran (27.6–52.4%) was the main compound in winter. These cyclic changes appear to be associated with the phenological stages of the plant during the year.

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 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.
