The solubility of quercetin, isoquercitrin, rutin, chrysin, naringenin, and hesperetin was quantified in acetonitrile, acetone, tert-amyl alcohol. strongly affected by both the nature solvent flavonoid structure. highest obtained acetonitrile for (85 mmol·L-1) naringenin (77 acetone (80 quercetin. lowest value with rutin acetonirile (0.50 mmol·L-1). thermodynamic properties flavonoids were also measured (melting point, enthalpy fusion, solid heat capacity) predicted (liquid capacity, phase...
The conversion yield at equilibrium, the initial rate, and regioselectivity of enzymatic acetylation aglycone flavonoids (quercetin, naringenin, hesperetin, chrysin) were investigated compared to those obtained with a glycosylated one (isoquercitrin). effects wide range operating conditions quantified. Fourier transform infrared spectrometry (FT-IR), NMR, high performance liquid chromatography electrospray ionization mass (HPLC–ESI–MS) analyses showed that for flavonoids, in presence Candida...
Summary Polyphenols were extracted from the skin of jabuticaba fruits ( M yrciaria cauliflora ). Their total concentration and in vitro antioxidant activity analysed by DPPH ABTS methods. The corresponding results (dry basis) 1290 mg gallic acid equivalent GAE )∙(100 g) −1 , 98% radical inhibition 120 μ m TEAC ∙g method). All these values are at least as higher average reported literature for other fruits. A more specific analysis fractions phenolic compounds was also performed HPLC ‐ MS ....
A strategy to infer solubilities from the combination of experiment and all-atom simulations is presented. From a single experimental estimate, solubility substrate can be predicted in various environments related free energies solvation. In case quercetin, methodology was shown reproduce chloroform, water, acetonitrile, acetone, tert-amyl alcohol within 0.5 log unit. The reliability estimates markedly correlated accuracy measure both precision computed
