Tanacetum argenteum (Lam.) Willd. subsp. flabellifolium (Boiss. & Heldr.) Grierson of Asteraceae is an endemic species in Turkey. Hydrodistillation of aerial parts using a Clevenger apparatus yielded an essential oil, which was subsequently analyzed by gas chromatography-mass spectroscopy (GC-MS). alpha-Pinene (29%), (E)-sesquilavandulol (16%), and camphor (14%) were found as main constituents....

A sensing method based on resonance localized surface plasmon spectroscopy was developed for low molecular weight substrate and inhibitor molecules binding to heme proteins. Cytochrome P450 proteins have Soret and Q absorption bands in the visible wavelength region. The coupling between the molecular resonance of P450 and the localized surface plasmon resonance (LSPR) of functionalized silver n...

In this study, the residues of camphor wood were used to produce activated carbon by pyrolysis. The prepared carbon was treated by potassium dihydrogen phosphate and then used as a solid phase adsorbent for the removal of p-nitroaniline (PNA) from aqueous solutions. A commercial camphor activated carbon (CC) adsorbent was selected for comparison purposes. Liquid phase adsorption experiments wer...

this study was conducted to evaluate the effect of camphor levels on performance, organ weight, testosterone and thyroid hormones, intestinal selective bacteria, and meat peroxidation of japanese quail. two-hundred 1-d chicks were allocated in 20 cages with five treatments and four replicates (10 chicks per each cage) using complete randomized block design. treatments were including: 0, 62.5, 1...

PURPOSE In Iranian traditional medicine there is a belief that camphor is a suppressor of sexual activity. Based on this idea and since there are few studies on this issue, we evaluated the effect of camphor on histopathological changes of reproductive system in young male mice of balb/c racial type. MATERIALS AND METHODS Thirty-six premature male balb/c mice, were divided into 3 paired group...

A new detection mechanism has been developed for low molecular weight substrate binding to heme proteins based on resonance localized surface plasmon spectroscopy. Cytochrome P450 has strong electronic transitions in the visible wavelength region. Upon binding of a substrate molecule (e.g., camphor), the absorption band of cytochrome P450 shifts to shorter wavelength. The event of camphor bindi...

Platinum(II) catalyzes the isomerization of camphor sulfonamide diynes in a cascade reaction involving annulation of a five-membered ring to the camphor skeleton, ring-enlargement by C-C bond cleavage, reduction of sulfur(VI) to sulfur(IV), and oxidation of a hydroxy group to a ketone. The reactions of the diynes with other transition metal compounds were also studied. Copper, gold and rhenium ...

1. The metabolism of (+/-)-norcamphor, (+)-camphor, (-)-camphor, (+)-epicamphor, (+/-)-camphorquinone, (+/-)-camphane-2,5-dione and camphane was investigated in rabbits. All the compounds except camphane-2,5-dione increased the content of glucuronide in the urine. 2. (+/-)-Norcamphor was reduced to endo-norborneol; (+)-camphor, contrary to expectation, was reduced to (+)-borneol, as well as bei...

13CO NMR chemical shifts and 12CO infrared stretching frequencies have been measured for cytochrome P-450cam-CO in the presence of D-camphor and of various camphor analogues. A linear correlation between both parameters delta (13C) and v(CO) was found indicating that the steric and electrostatic interactions acting on the CO ligand are influenced by the substrate. It has been proved that P-450 ...
