Total phenolics, flavonoids, antioxidant activity, crude fibre and digestibility in non-traditional wheat flakes and muesli

Phytochemical Analysis, Quantitative Estimations of Total Phenols and Free Radical Scavenging Activity of Bupleurum subovatum from Jerusalem

“…35 1 mg/ml aqueous solutions for both methanolic extracts were prepared in the analysis. The reaction mixture was prepared by mixing 0.5 ml of plant extract solution, 2.5 ml of 10% Folin-Ciocalteu's reagent dissolved in water and 2.5 ml of 7.5% of NaHCO 3 aqueous solution.…”

Preparation and Characterization of Rutin-loaded Nanophytosomes

“…7,8 Flavonoids are a class of phenolic compounds that exhibit powerful antioxidant effects in biological systems (including free radical scavenging) however, their efficiency considerably depends on chemical features. 9,10 Flavonoids are classified, according to chemical structure, into flavonols, flavones, flavanones, isoflavones, catechins, anthocyanidins and chalcones. Flavonoid are hardly absorbed from the small intestine because of the sugar moieties which increases their hydrophilicity.…”

Caracteristicas fitoquímicas y capacidad antioxidante in vitro de Aloe vera, Plukenetia volubilis, Caiophora carduifolia, Cecropia membranácea

“…De todos los metabolitos secundarios, los compuestos fenólicos muestran una correlación lineal entre la concentración y la capacidad antioxidante expresada en equivalentes de trolox y ácido ascórbico (25) ; en especial los flavonoides (26) y asimismo los fitoesteroles como el β-sitosterol poseen también dicho efecto leve o moderado in vitro, reduciendo el estrés oxidativo causado por la administración de 1,2-dimetilhidracina durante la inducción de carcinogénesis en colon de ratas (27) .…”
