Abstract: In the title mol­ecule, C19H20O6, the conformation about the C=C bond of the central enone group is E. The dihedral angle formed by the benzene rings is 11.6 (2)°. The hy­droxy group is involved in an intra­molecular O-H...O hydrogen bond. In the crystal, weak C-H...O hydrogen bonds link the mol­ecules into chains along [010].
