“…Finally, the lH equation which proposed rstly by Buchowski et al 33 is also used as an optional model for correlation of the solubility of naringin with temperature. The Buchowski lH equation is included only two adjustable parameters; l and H, and is expressed as:…”

This study describes the thermodynamics of dissolution of flavonoid naringin in different aqueous solutions of dimethyl sulfoxide (DMSO) containing 0-100% (w/w) under atmospheric pressure and over a temperature range of 298.15 to 325.15 K. The temperature dependence of solubility of naringin was analyzed using the modified Apelblat equation model, ideal model, and the lH equation model. In a mean harmonic temperature, the dissolution thermodynamic parameters of naringin containing DG sol , DH sol and DS sol were also calculated. Furthermore, the effects of solvent composition on the solubility of this flavonoid were analyzed in terms of Hildebrand's solubility parameter (d H ) and Kamlet, Abboud and Taft (KAT) solvatochromic parameters (a, b, and p*). Finally, the preferential solvation parameters of the flavonoid naringin by DMSO (dx DMSO,S ) were determined from experimental solubility data using the inverse Kirkwood-Buff integrals (IKBIs). It was found that water preferentially solvates naringin in waterrich mixtures while DMSO forms local solvation shells in compositions from 50% (w/w) or x DMSO ¼ 0.19 up to pure co-solvent. Moreover, the structure of solvation shells of naringin in the under study mixtures was obtained by molecular dynamics (MD) simulations. The computational results showed that in the compositions x DMSO > 0.20, the probability of presence of the DMSO molecules in vicinity of naringin is more than water molecules. These findings are compatible with the available IKBI data.

“…Buchowski and Khiat [13] suggested the CNIBS/R-K model could be one of the theoretical models for calculating the solute solubility in binary solvents. This model is represented by Mole fraction solubilities of Lansoprazole (A) in (isopropyl alcohol (B) + acetone (C)) at temperatures in the range (283.15-308.15 K) at atmospheric pressure.…”
