ABSTRACT
The solubilities of trans-resveratrol in different compositions of ethanol + water mixtures and acetone + water mixtures were measured at different temperatures. The solubilities of trans-resveratrol in ethanol + water mixtures increase with increasing mole fraction of ethanol, whereas the solubility curve (the solubilities vs the mole fraction of acetone on solute-free basis) of an acetone + water mixed system presents a maximum. The solubilities of trans-resveratrol in both mixture systems increase with increasing temperature. The experimental solubility data were correlated by a three-parameter empirical equation and UNIQUAC model, respectively.
