The sonoextraction (SE) of aescin saponins and phenolic compounds from the inedible seed kernels Aesculus hippocastanum was optimized using a central composite rotatable design coupled with response surface methodology, where joint effects ultrasonic power, sonication time, ethanol proportion were investigated. Flavonol glycosides (≥90 % fraction), flavan-3-ols, acids, identified by HPLC-DAD-ES...

background: the genus lomatopodium fisch. & c.a.mey., belongs to apiaceae family and contains one herbaceous species growing wildly in iran. there are only a few papers about the chemical constituents of these plants. here, we focused on the isolation and identification of the main flavonoid glycosides and sterols from the aerial parts of l. staurophyllum, which has not been previously reported...

Hyperoside, also known as quercetin-3-O-?-D-galactopyranoside, belongs to the class of flavonol glycosides. Its aglycon is quercetin, and sugar base galactopyranoside. It made quercetin. The O atom at 3rd position element connected group by a ?-glycosidic bond. Hyperoside, which widely present in planted objects, such fruits whole plants Hypericaceae, Rosac...

Recent experimental data point to an interaction of dietary flavonol monoglucosides with the intestinal Na-dependent glucose transporter 1 (SGLT1). To investigate this interaction in more detail, we performed experiments with SGLT1-containing brush-border-membrane vesicles (BBMV) from pig jejunum. The flavonol quercetin-3-O-glucoside (Q3G) concentration-dependently inhibited Na-dependent uptake...
