ABSTRACT
The solubility of 1,6,6-trimethyl-6,7,8,9-tetrahydrophenanthro[1,2-b]furan-10,11-dione (tanshinone IIA) in ethanol, methanol, acetone, and ethyl acetate from (283.2 to 323.3) K was measured. The solubility of tanshinonone IIA in these solvents increases with increasing temperature. The solubility values were correlated with the Apelblat equation.
