In the present study, the solubility of limonin in eight organic solvents and a binary solvent system (ethyl acetate + 2-propanol) was determined by the high-performance liquid chromatography analysis method within the temperature range from 283.2 to 323.2 K. The results showed that the solubility of limonin increased with temperature in the eight pure solvents and the binary solvent mixtures. In the binary solvent system ethyl acetate + 2-propanol, the solubility decreased with the initial mole fraction of ethyl acetate. The experimental solubility of limonin was well correlated with temperature by the simplified thermodynamic equation, modified Apelblat equation, λh equation, and NRTL equation. Furthermore, the solubility of limonin in the binary solvent mixtures was correlated with both temperature and initial solvent composition of the binary solvent mixtures by the Jouyban−Acree model, van't Hoff−Jouyban−Acree model, modified Apelblat−Jouyban−Acree model, Ma model, Sun model, and NRTL model. Finally, the thermodynamic properties of the mixing process, including mixing Gibbs energy, mixing enthalpy, and mixing entropy, were also calculated.

“…In this work, the solubility data of genistin in different solvents were correlated by several models to quantitatively describe the solid–liquid equilibria. For a fixed solvent, a simplified thermodynamic model (eq S1, Supporting Information), , the modified Apelblat model (eq ), , and the λ h model (eq S2, Supporting Information) were used to correlate the solubility with temperature.…”

The solubilities of genistin in the binary solvent mixtures ethanol + water and acetone + water with various initial mole fractions were measured by high-performance liquid chromatography (HPLC) at different temperatures ranging from 278.2 to 313.2 K. An interesting phenomenon was observed, namely, a synergistic effect of the binary solvent mixtures on solubility. In this synergistic effect, the solubility of genistin reached a maximum and was higher than its solubility in the separate solvents when the initial mole fraction of ethanol or acetone was 0.5 throughout the whole range of temperatures studied. The solubility of genistin in the mixtures increased with temperature. A simplified thermodynamic model, the modified Apelblat model, and the λh model were used to correlate the solubility data of genistin with temperature. Among the three models, the modified Apelblat model showed the best correlation in describing the dependence of the solubility on temperature. Furthermore, to illustrate the effects of both the temperature and the initial mass fraction of ethanol or acetone on the changes in the solubility of genistin, nonrandom two-liquid (NRTL), Sun, and Ma models were also used to correlate the data. The results showed that the solubilities calculated by the Sun model showed better agreement with the experimental data than those calculated by the other two models.

“…Related to solubility, it has been found that, e.g., dissolving daidzein in acetonitrile as compared to water, reduces the energetic difference between various electronic states (Orozco-Gonzalez et al, 2013); in acetonitrile, daidzein is more likely to interchange among charged states and different geometries. Correspondingly, the solubility of daidzein is double in acetonitrile as compared to water over a broad temperature range (Fan et al, 2015). It is important to note from the latter work, that, due to the closely matching energy-levels of the electronic arrangements, any re-emitting of light disappears due to the ease and manifold possibilities of internal conversion of the absorbed energy.…”
