the composition of essential oil of leaves of the male and female shrubs of juniperus chinensis l. (growing in isfahan) was analyzed by gas choromatography(gc) and gc-mass spectrometery (ms). the main constituents of leaf oil of the male shrub were: bornyl acetate (26.1%), sabinene (18.3%), trans-sabinyl acetate (11.1%), myrcene (9.2%), limonene (6.1%), elemol (5.5%), α-cadinol (2.3%), δ-cadine...
Studies on the feeding deterrent activity of some natural, cyclic terpenes (myrcene, (+)-3-carene, (+)-limonene, (±)-camphene), synthetic alkenes (2-methyl-1-pentene, 2,4,4-trimethyl-1-pentene, 1-methylcyclohexene, 1-tetradecene) and their derivatives α-methylenelactones in choice and no-choice tests against Colorado potato beetle with potato, Solanum tuberosum L. leaf discs as consuming food w...
In this study, both qualitative and quantitative analyses of chemical composition of M. purpurea essential oil obtained in the Deryng and Clevenger-type apparatuses were compared. As a result, content of volatile compounds were: 785.67 mg/mL and 833.33 mg/mL in the oil obtained in the Deryng (D-EO) and Clevenger-type apparatuses (C-EO), respectively. The major components of both essential oils ...
Inhalable, noncombustible cannabis products are playing a central role in the expansion of the medical and recreational use of cannabis. In particular, the practice of "dabbing" with butane hash oil has emerged with great popularity in states that have legalized cannabis. Despite their growing popularity, the degradation product profiles of these new products have not been extensively investiga...
The essential oils of Piper cernuum and Piper regnellii leaves were analyzed by gas chromatography-mass spectrometry (GC-MS) and the results were compared to that obtained by means of a program designed to analyse (13)C-NMR data of complex mixtures. Bicyclogermacrene (21.88 %)/beta-caryophyllene (20.69 %) and myrcene (52.60 %)/linalool (15.89 %) were the major constituents in essential oil from...
Capillary GC and GC-MS analysis of the essential oil from the cones of JUNIPERUS COMMUNIS L. grown wild in Greece showed a high content of alpha-pinene (ca 27%), sabinene (13%), germacrene-D (10%), and myrcene (9%). The total oil (yield 2.95%) consisted of almost 105 constituents, 77 of which representing 93.1% were identified. As the main component of the oxygenated monoterpenes was found the ...
Coordination in honeybees is heavily dependent on their chemoreception system, which odorant-binding proteins are very important. A previous study based the antennal transcriptome of Apis cerana revealed that OBP15 was significantly up-regulated at 25-day-old. To further unravel and clarify its functional role, we first cloned characterized AcerOBP15 from antennae worker bees. Sequence phylogen...
