Measuring and validation for isothermal solubility data of solid 2-(3,4-Dimethoxyphenyl)-5,6,7,8-tetramethoxychromen-4-one (nobiletin) in supercritical carbon dioxide

•Solubility of nobiletin in supercritical carbon dioxide was obtained.•Measured at T=(313, 323, and 333)K and at (17.97 to 31.40)MPa.•Correlated with empirical equation expressed in terms of SC-CO2 density.•Binary interaction parameters were fitted from experimental data using PR-EOS with Wong–Sandler mixing rule.•Thermodynamic consistency of phase equilibria data was evaluated using the G–D equation.
