A set of O-substituted quercetin derivatives was prepared with the aim to optimize bioavailability and redox properties of quercetin, a known agent with multiple health beneficial effects. Electron-acceptor/-donor properties of the agents were evaluated theoretically by quantum chemical calculations and by experimental methods in cell-free model systems (2,2-diphenyl-1-picrylhydrazyl (DPPH) test,...
The n-butanol fraction (BF) of bark of Pecan tree, Carya illinoinensis (Wangenh) K. Koch (Juglandaceae) afforded two new flavonol methyl ether: caryatin-3′ sulfate (6) and caryatin-3′ methyl ether-7-O-β-d-glucoside (7) while five known phenolics (1–5) were isolated from its ethyl acetate fraction (EAF). The structures of isolated compounds were established based on 1D and 2D NMR spectroscopy. The...
