The cypress jewel beetle, Ovalisia festiva L. (Coleoptera: Buprestidae, Chrysochroinae), and the bark Phloeosinus aubei Perris Curculionidae, Scolytinae), are invasive wood-boring pests of scale-leafed conifers (Cupressaceae), threatening tree nurseries urban green areas. In order to reveal which volatile compounds their common host, American arborvitae, Thuja occidentalis cultivar ‘Smaragd’, t...

In this article we investigate the effect of multivalency in chiral recognition. To this end, we measured the host-guest interaction of a β-cyclodextrin dimer with divalent chiral guests. We report the synthesis of carbohydrate-based water soluble chiral guests functionalized with two borneol, menthol, or isopinocampheol units in either (+) or (-) configuration. We determined the interaction of...

BACKGROUND Aedes aegypti L. is the major vector of dengue fever and dengue hemorrhagic fever. In an effort to find effective tools for control programs to reduce mosquito populations, the authors assessed the acute toxicities of 14 monoterpenoids, trans-anithole and the essential oil of rosemary against different larval stages of Ae. aegypti. The potential for piperonyl butoxide (PBO) to act as...

Common sage (Salvia officinalis L.; Lamiaceae) is one of the most important herb known for its essential oil richness and extensive use in folk medicine. In the current study, we determined the effects of three drying methods on the chemical composition of the essential oil of Saliva officinalis L. The aerial parts of Saliva officinalis were collected from Iran at the full-flowering stage and d...

The rationale of this investigation was to examine the antinociceptive properties of the essential oil obtained from Rosmarinus officinalis aerial parts, using a rat model of arthritic pain. The essential oil (100, 300 and 600 mg/kg, I. P.) produced a dose-dependent antinociceptive effect, manifested as a significant reduction in the dysfunction in the pain-induced functional impairment model i...

Endemic yarrow (Achillea eriophora DC.) has been widely used in folk medicine for centuries. The impact of climatic and edaphic conditions was investigated on essential oil (EO) yield and compositions of different yarrow ecotypes, native to Kerman province in southeast of Iran. The aerial part of plants was collected from 13 naturalhabitats. Gas chromatography-mass spectrometry (GC-MS) analysis...

A review on a medicinal plant belong to family Labiatae has been made in the Kingdom of Saudi Arabia. Among reported flora Arabia, highest species. total 23 species with high value. detail 12 had done know their phytochemical constituents, uses and pharmacological properties. In this we also explore chemical constituents present each unique list 3D structures. (E)-2-Hexenal, 1,8-Cineole, Bicycl...
