ABSTRACT
The solubilities of apigenin in ethanol + water mixtures at T = (273.2 to 323.2) K were measured by using high-performance liquid chromatography (HPLC). The solubilities of apigenin increase with increasing temperatures and go through a maximum at a specific solvent composition. The experimental data of solubilities were correlated by a three-parameter empirical equation.
