Abstract

The title compound {systematic name: 4-[(E)-2-(3,5-dihy­droxy­phen­yl)ethen­yl]benzene-1,3-diol dihydrate}, C14H12O4·2H2O, a derivative of resveratrol, was isolated from mulberry. The linking C=C double bond has a trans conformation and allows the formation of a conjugated system throughout the mol­ecule. The dihedral angle between the benzene rings is 9.39 (9)°. In the crystal, mol­ecules are connected into a three-dimensional architecture through O—H⋯O hydrogen bonds between hy­droxy groups of oxyresveratrol and solvent water mol­ecules.
