Wheat phenolic compounds have benefits of maintaining health and reducing risks some chronic diseases cancers. breeders producers are becoming interested in producing specialty wheat with a higher amount bioactive phenolics, addition to the conventional targets yield, disease pest resistance, milling baking quality, etc. Generally, total content (TPC) is determined using Folin-Ciocalteu reagent...

The solubility of tris(pentane-2,4-dionato)chromium(III) (Cr(acac)(3)) in supercritical carbon dioxide (SC-CO(2)) containing organic modifiers (1,1,1,3,3,3-hexafluoro-2-propanol (HFP) and 3,5-bis(trifluoromethyl)phenol (BTMP)) of hydrogen-bond donors was investigated by UV/VIS spectrophotometry. A great solubility enhancement of Cr(acac)(3) in SC-CO(2) was accomplished by adding HFP and BTMP. T...

Protective capabilities were studied of carboxymethylated (1-->3)-beta-D-glucan from Saccharomyces cerevisiae cell wall against lipid peroxidation in phosphatidylcholine liposomes induced by OH radicals produced with Fenton's reagent (H2O2/Fe2+) and also by microwave radiation using absorption UV-VIS spectrophotometry. A significant decrease in the conjugated diene production, quantified as Kle...
