this study was done to evaluate quality properties of pistacia atlantica var mutica (bene) nuts under deferent storage conditions and packaging. at the zero time, sfa and total tocopherol (tt) and total phenolic (tp) compounds were 6.8 and 725.28 and 40.1 mg per kg oil, respectively. some quality properties (peroxide value (pv), conjugated diene value (cdv) and carbonyle value (cv)) showed that...

Arenes have been widely used as 7r-accepting ligand in organometallic chemistry. Particularly, arene complexes of the tricarbonylchromium frag­ ment have found applications as catalyst in the synthesis of organic compounds including several biochemical interest [1] and therefore been studied extensively [2]. Complexes of conjugated diene of the tetracarbonylchromium fragment are also well chara...

Activated neutrophils releasing proteolytic enzymes and oxygen free radicals have been implicated in extending myocardial injury after myocardial infarction. Neutrophil elastase was used as a marker of neutrophil activation and the non-peroxide diene conjugate of linoleic acid was used as an indicator of free radical activity in 32 patients after acute myocardial infarction; 17 were treated by ...

The study focused on the possibilities of evaluation red pepper (Capsicum Annuum L.) seeds being a food industry waste. moisture content (%), total crude oil and ash content, color, weight 1000 seeds, thickness diameter were characterized. oils extracted from using green techniques: cold-pressing, ethanol solvent, ultrasound-assisted solvent extraction.Different techniques compared production y...

Transmetallation: A highly regio- and diastereoselective carbocyclization involving a palladium-catalyzed 1,2-addition of two carbon atoms across a conjugated diene has been developed (see scheme). The reaction is performed with dienynes and an oxygen tether containing a terminal or internal triple bond.

BACKGROUND AND AIM Due to its high antioxidant and mono- and polyunsaturated fatty acid content virgin argan oil (VAO) could play a beneficial role in cardiovascular prevention. We were therefore interested in determining whether the consumption of VAO could improve plasma paraoxonase (PON1) activities and antioxidant status in healthy men. METHODS AND RESULTS Sixty young men were included in...

A new diene-conjugated chromophore WJ1 was synthesized with high yield of 36% through an H-bonding induced Vilsmeier reaction. By simple guest-host doping, a large electro-optic efficiency of 337 pm V(-1) at 1310 nm and excellent temporal stability at 75 °C have been achieved in poled films of WJ1/APC with a high loading density of 40 wt%.

The total synthesis of the architecturally complex Daphniphyllum alkaloid (-)-calyciphylline N has been achieved. Highlights of the synthesis include a Et2AlCl-promoted, highly stereoselective, susbtrate-controlled intramolecular Diels-Alder reaction, a transannular enolate alkylation, an effective Stille carbonylation/Nazarov cyclization sequence, and a high-risk diastereoselective hydrogenati...

An addition/elimination sequence of selenium halides to pseudo-geminally bis(acetylene) substituted [2.2]paracyclophanes leads to new bridges with an endo-exo-diene substructure. The reactions have been found to be sensitive to the substitution of the ethynyl group. The formation of dienes with a zig-zag configuration is related to that observed for non-conjugated cyclic diynes of medium ring s...
