Priestley, C. M. published the artcileLethality of essential oil constituents towards the human louse, Pediculus humanus, and its eggs, Recommanded Product: 2-(2-Hydroxypropan-2-yl)-5-methylcyclohexanol, the main research area is insecticide ovicide essential oil Pediculus humanus.

Essential oils have been widely used in traditional medicine for the eradication of lice, including head lice, but due to the variability of their constitution the effects may not be reproducible. In an attempt to assess the contribution of their component monoterpenoids, a range of common individual compounds were tested in in vitro toxicity model against both human lice (Pediculus humanus, an accepted model of head lice lethality) and their eggs, at different concentrations No detailed study into the relative potencies of their constituent terpenoids has so far been published. Adult lice were observed for lack of response to stimuli over 3 h and the LT50 calculated, and the percentage of eggs failing to hatch was used to generate ovicidal activity data. A ranking was compiled for adult lice and partially for eggs, enabling structure-activity relationships to be assessed for lethality to both, and showed that, for activity in both life-cycle stages, different structural criteria were required. (+)-Terpinen-4-ol was the most effective compound against adult lice, followed by other mono-oxygenated monocyclic compounds, whereas nerolidol was particularly lethal to eggs, but ineffective against adult lice.

Singh, Harminder Pal published the artcileAssessment of in vitro antioxidant activity of essential oil of Eucalyptus citriodora (lemon-scented Eucalypt; Myrtaceae) and its major constituents, Synthetic Route of 42822-86-6, the main research area is essential oil Eucalyptus citriodora antioxidant.

We investigated the chem. composition and antioxidant activity of Eucalyptus citriodora (lemon-scented eucalyptus) leaf oil in terms of total antioxidant activity, ferric reducing antioxidant power (FRAP) assay, ferrous ion chelating activity, and scavenging of hydrogen peroxide (H2O2) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals and inhibition of lipid peroxidation GC-MS anal. of essential oil revealed the presence of 43 components constituting 99.2% of oil. The oil was monoterpenoid (94.35% of oil) with citronellal (60.66%), β-citronellol (12.58%) and isopulegol (8.19%) as the major monoterpenoids. Oil and its major monoterpenes exhibited moderate to strong antioxidant activity in terms of TAA, FRAP and Fe+2 chelating, DPPH and H2O2 scavenging, and lipid peroxidation inhibition. The study concludes that E. citriodora leaves contain monoterpenoid rich oil exhibiting antioxidant activity.

Cannon, Robert J. published the artcileIdentification, Synthesis, and Characterization of Novel Sulfur-Containing Volatile Compounds from the In-Depth Analysis of Lisbon Lemon Peels (Citrus limon L. Burm. f. cv. Lisbon), HPLC of Formula: 42822-86-6, the main research area is lemon peel flavor aroma volatile sulfur compound; GC-MS; GC-O; lemons; volatile sulfur compounds.

Lemons (Citrus limon) are a desirable citrus fruit grown and used globally in a wide range of applications. The main constituents of this sour-tasting fruit have been well quantitated and characterized. However, addnl. research is still necessary to better understand the trace volatile compounds that may contribute to the overall aroma of the fruit. In this study, Lisbon lemons (C. limon L. Burm. f. cv. Lisbon) were purchased from a grove in California, USA, and extracted by liquid-liquid extraction Fractionation and multidimensional gas chromatog.-mass spectrometry were utilized to sep., focus, and enhance unidentified compounds In addition, these methods were employed to more accurately assign flavor dilution factors by aroma extract dilution anal. Numerous compounds were identified for the first time in lemons, including a series of branched aliphatic aldehydes and several novel sulfur-containing structures. Rarely reported in citrus peels, sulfur compounds are known to contribute significantly to the aroma profile of the fruit and were found to be aroma-active in this particular study on lemons. The identification, synthesis, and organoleptic properties of these novel volatile sulfur compounds are discussed.

Kurnia, Irwan published the artcileSynthesis of p-menthane-3,8-diol from citronellal over lignin-derived carbon acid catalysts, Safety of 2-(2-Hydroxypropan-2-yl)-5-methylcyclohexanol, the main research area is menthanediol citronellal lignin carbon acid catalyst.

P-Menthane-3,8-diol (PMD) is receiving growing attention as a natural mosquito repellent with lower toxicity compared to the widely-used N,N-di-Et m-toluamide (DEET). In this study, sustainable carbon acid catalysts derived from alk. lignin (AL) were prepared for synthesizing PMD from a popular chem. (±)-citronellal in an environmentally friendly solvent of water. The catalytic performances of the AL-derived carbon acid catalysts prepared at different pyrolysis temperatures were better than those of other catalysts such as carbon black and H-USY. In particular, when the AL pyrolyzed at 500°C was used as the carbon acid catalyst, the conversion of (±)-citronellal was as high as 97% with a high PMD yield of 86%, indicating that waste alk. lignin from pulp and paper industries can be used as a source of acid catalysts. It is found that the formation of PMD is preferred over catalysts with weaker acid sites, whereas isopulegol was more easily formed over stronger acid sites. Moreover, the reaction route of the citronellal cyclization-hydration reaction was more dominant via the carbocation-hydration pathway rather than the isopulegol hydration route on the weaker carbon acid catalyst.

von Poser, Gilsane L. published the artcileEssential Oil Composition and Allelopathic Effect of the Brazilian Lamiaceae Hesperozygis ringens (Benth.) Epling and Hesperozygis rhododon Epling, Computed Properties of 42822-86-6, the main research area is Hesperozygis oil composition; terpene Hesperozygis oil.

Samples of Hesperozygis ringens (Benth.) Epling and Hesperozygis rhododon Epling essential oils were analyzed by a combination of anal. techniques: capillary gas chromatog., liquid/solid chromatog., GC/MS coupling, and NMR spectroscopy. Twenty-four components have been identified representing altogether more than 95% of the oil content. The oil of H. ringens is constituted mainly by pulegone (79.2%) accompanied by several oxygenated derivatives (pulegone oxides, 1.2%; 8-hydroxy-p-menth-3-one, 1.3%; and 8-hydroxy-p-menth-4-en-3-one, 3.7%); that of H. rhododon contains menthone and pulegone as main compounds in almost comparable amounts (43.4% and 29.6%, resp.). Tests carried out on lettuce seeds using alc. extracts of the two species showed significant antigerminating properties mainly for H. ringens. The same activity was observed with its essential oil.

Gbenou, Joachin D. published the artcilePhytochemical composition of Cymbopogon citratus and Eucalyptus citriodora essential oils and their anti-inflammatory and analgesic properties on Wistar rats, Safety of 2-(2-Hydroxypropan-2-yl)-5-methylcyclohexanol, the main research area is Cymbopogon Eucalyptus essential oil antiinflammatory analgesic.

Cymbopogon citratus and Eucalyptus citriodora are widely used herbs/plants as a source of ethnomedicines in tropical regions of the world. In this work, the authors studied the anti-inflammatory and gastroprotective effects of C. citratus and E. citriodora essential oils on formol-induced edema, and acetic acid induced abdominal cramps in Wistar rats. To fully understand the chem. induced anti-inflammatory properties of these plants, the authors first analyzed the chem. composition of the essential oils. A total of 16 chem. constituents accounting for 93.69 % of the oil, were identified in C. citratus among which, Geranial (27.04 %), neral (19.93 %) and myrcene (27.04 %) were the major constituents. For E. citriodora, 19 compounds representing 97.2 % of the extracted oil were identified. The dominant compound of E. citriodora essential oil was citronellal (83.50 %). In vivo anal. and histol. assay showed that the 2 essential oils displayed significant dose dependent edema inhibition effect over time. They displayed strong analgesic and antipyretic properties similar to that induced by 50 mg/kg of acetylsalicylate of lysine. However, the E. citriodora essential oil was more effective than that of C. citratus. The authors identified significant numbers of aldehyde mols. in both essential oils mediating antioxidant activity that may contribute to the anti-inflammatory effects observed on the rats. Altogether, this work demonstrates the anti-inflammatory property of C. citratus and E. citriodora suggesting their potential role as adjuvant therapeutic alternatives in dealing with inflammatory-related diseases.
