In the title compound, C21H24O3, the conformation of the enone group is s–cis.The benzene rings are inclined at an angle of 7.9 (1)°.The alkoxy tail is planar, with a maximum deviation from the least-squares plane of 0.

009 (2) Å, and adopts gladioli espresso a trans conformation throughout.An intramolecular O—H.O interaction between the keto and hydroxy groups forms S(6) ring motifs.In the crystal, molecules are arranged in a head-to-tail manner down the a axis and are subsequently stacked along the b axis, forming molecular sheets parallel case of whispering angel to the ab plane.

The crystal structure is further stabilized by weak C—H.π interactions and short C.O [3.376 (2) Å] contacts.
