Flavonoids are among the most important bioactive compounds responsible for the medical properties of honey and propolis. Water is the solvent most commonly used to extract flavonoids from honey and propolis. Hydrogen-bonding interactions are of great importance in the extraction process. In this work, hydrogen-bonding interactions between a representative flavonoid, luteolin, and water were investigated...
Ethanol and water are the solvents most commonly used to extract flavonoids from propolis. Do hydrogen-bonding interactions exist between flavonoids and ethanol/water? In this work, this question was addressed by using density functional theory (DFT) to provide information on the hydrogen-bonding interactions between flavonoids and ethanol/water. Chrysin and Galangin were chosen as the representative...
