The title compound, [Sb(C(5)H(10)NS(2))(3)], was synthesized from Sb(2)O(3), diethyl-amine, carbon dis-ulfide, hydro-chloric acid and sodium hydroxide. The structure has been published previously but H atoms were not included in the model [Raston & White (1976 ▶). Chem. Soc. Dalton Trans. p. 791]. The current determination has significantly higher precision than the original work. The complex h...
In the title tetrasubstituted guanidine, C(18)H(21)N(3)O, the guanidine and carbonyl groups are not coplanar, as reflected by the torsion angles involving the N=C atoms [17.6 (3), -141.68 (17) and 42.2 (3)°]. This is probably due to the absence of an intra-molecular N-H⋯O hydrogen bond, forming a six-membered ring, and is commonly observed in this class of compounds. In the crystal structure, c...
meat products, especially fish meat, are very susceptible to lipid oxidation and microbial spoilage. in this study, first, gas chromatography mass spectrometry (gc-ms) analysis of zataria multiflora essential oil (zeo) components was done and then two concentrations of zeo, (1% and 2%) and two concentrations of grape seed extract (gse), (0.5% and 1%) were used in carboxymethyl cellulose coating...
Plants are excellent sources of secondary metabolites that have been used for the treatment human diseases. The plant Momordica cymbalaria contains different types phytochemicals like phenols, steroids, flavonoids, alkaloids and tannins. present investigation was carried out to determine bioactive compounds in parts by Gas chromatography- Mass spectroscopy (GC-MS) technique. Chromatograms vivo ...
this study was carried out to evaluate how various amounts of nanozeolite decrease the effects of aflatoxins (af) on color and oxidative stability of the broiler thigh meat. three hundred and thirty six one-day-old ross 308 male broiler chickens were divided into six groups including a control group, which received diet without af and nanozeolite, and five treatment groups that received diet wi...
