In the title compound, C27H36O5, both the cyclohexenone rings adopt envelope conformations.
In the title compound, C27H36O5, the dihedral angles between the planes of the benzene ring and the cyclohexenone rings are 60.87 (10) and 65.04 (10)°, while the dihedral angle between the mean planes of the two cyclohexenone rings is 39.33 (10)°. Each cyclohexenone ring has a carbon atom bonded to two methyl groups, which acts as the flap atom, resulting in an envelope conformation. The opposite orientation of the hydroxy and carbonyl oxygen atoms allows for the formation of two intramolecular O—H⋯O hydrogen bonds and C—H⋯π (ring) interactions also help to establish the molecular conformation.
