The constituents of the essential oil of Stachys laxa Boiss. & Buhse growing wild in Iran were investigated by GC-MS for the first time. Thirty-three constituents were identified. Germacrene-D (40.1%), b -caryophylene (16.7%), b -phellandrene (5.5%), caryophyllene oxide (4.6%), linalool (3.2%) and ?-cadinol (2.6%) were found to be the major constituents of the oil.

the main objective of this study was to determine the effects of biofertilizers on quantity and quality of essential oil of basil essential oil content, geranial, caryophyllene, caryophyllene oxide and methyl chavicol in essential oil. the experiment was carried out as randomized complete blocks design with eight treatments and three replications at research field of agriculture company of ran ...

The first step in the conversion of the isoprenoid intermediate, farnesyl diphosphate (FDP), to sesquiterpene phytoalexins in cotton (Gossypium barbadense) plants is catalyzed by delta-cadinene (CDN) synthase. CDN is the precursor of desoxyhemigossypol and hemigossypol defense sesquiterpenes. In this paper we have studied the mechanism for the cyclization of FDP and the putative intermediate, n...

BACKGROUND Sensitive or hyperreactive skin is a common condition defined by prickling, burning, pain, and pruritus. Although this skin problem was initially described on the face, the scalp is often affected. A sensitive scalp can react with irritation to harsh surfactants or other additives which are often present in shampoos. For this reason, we developed a new rinse-off hypertolerant shampoo...

In this work we present an investigation of the effect of oxide thickness on annealed B diffusion profiles. Experiments were specifically designed to determine the effect of varying oxide thickness on the B diffusion profile after annealing. Boron was implanted through a 50 Å screen oxide. Implant oxide was etched to varying degrees on different samples resulting in screen oxide thickness from ...

Polyethylene oxide –b– polypropylene oxide -bpolyethylene oxide (EO106PO70EO106) block copolymer self-organizes into polymeric supramolecules, characterized by NMR as phase transition from the isotropic stack-up block structure to the ordered cubic polymeric supramolecular structure. Its dependence on both temperature and copolymer concentration is clearly shown by the changes in line shape and...
