Exploring green solvent systems and enhanced solubility of xanthone in triglyceride-based tricaprin-tricaprylin mixtures with thermodynamic insights.

This study explores the use of green solvent systems by investigating the solubility and thermodynamic properties of xanthone (1) in triglyceride-based tricaprin (2) and tricaprylin (3) mixtures, aiming to replace traditional organic solvents. The solubility profile exhibited a concave trend, and the highest solubility was observed at a solute-free fraction (x) of 0.36.
