چکیده
In the title chalcone derivative, C(18)H(18)O(5), the dihedral angle between the hy-droxy-substituted benzene ring and the trimeth-oxy-substituted benzene ring is 16.3 (1)°. The three meth-oxy groups are essentially coplanar with the benzene ring to which they are attached, with an r.m.s. deviation of 0.0208 Å. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, weak C-H⋯O inter-actions link mol-ecules into helical chains along the b axis. These chains are connected into sheets parallel to the bc plane by further weak C-H⋯O inter-actions.
