Solubility of Quercetin in Water + Methanol and Water + Ethanol from (292.8 to 333.8) K

The solubilities of quercetin in water + methanol and water + ethanol mixtures were measured over the temperature range of (292.8 to 333.8) K. The concentrations of quercetin in different solvent mixtures were analyzed by the UV/vis spectrophotometric method. The experimental solubility data were correlated with the modified Apelblat equation. The calculated solubilities show good agreement with the experimental solubility data.
