摘要：

The title compound, C17H14O4, a homoisoflavanoid, was isolated from the twigs and stems of Caesalpinia digyna Rottler. The pyran ring adopts an envelope conformation. The symmetry-related molecules are linked via O-(HO)-O-... and C-(HO)-O-... intermolecular hydrogen bonds to form a molecular network.
