(E)-1-(2-Hy-droxy-6-meth-oxy-phen-yl)-3-(2,4,6-tri-meth-oxy-phen-yl)prop-2-en-1-one.

In the title mol-ecule, 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 hy-droxy group is involved in an intra-molecular O-H⋯O hydrogen bond. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into chains along [010].
