Whole-mol-ecule disordered (E)-2-(1-hy-droxy-3-phenylprop-2-en-1-yl-idene)-4,5-dimeth-oxycyclo-pent-4-ene-1,3-dione isolated from Lindera oxyphylla (Lauraceae).

In the mol-ecule of the title compound, C(16)H(14)O(5), all non-H atoms are approximately co-planar [maximum atomic deviation = 0.064 (5) Å]. The hy-droxy group is a hydrogen-bond donor to a carbonyl O atom. Weak intermolecular C-H⋯O hydrogen bonding is present in the crystal structure. The crystal structure is 'whole-mol-ecule disordered' about an axis that runs approximately along the length of the mol-ecule; the occupancy of the two disorder components was set as exactly 0.5. An intra-molecular O--H⋯O hydrogen bond exists in each component.
