title: 1-(5-Hydroxy-7-methoxy-2,2-dimethyl-2H-chromen-6-yl)ethan-1-one.
abstract: The title chromene, C(14)H(16)O(4), was isolated from the stems of Polyalthia plagioneura Diels. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, the mol-ecules are linked by C-H⋯O inter-actions, generating [010] chains.
