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-HO hydrogen bond. In the crystal, weak C-HO hydrogen bonds link the molecules into chains along .
