ABSTRACT
The solubilities of ursolic acid and oleanolic acid in four solvents (methanol, ethanol, 2-propanol, and ethyl acetate) are measured over the temperature range of (283.2 to 329.7) K. The experimental solubility data are correlated by the modified Apelblat equation. The root-mean-square deviation (rmsd) between the experimental value and the calculated value is not more than 1.1267*10-4, so the calculated solubility shows good agreement with the experimental data.
