The title compound, C10H15NO7, consists of one methylenedioxy ring and two fused tetrahydrofuran rings. The three fused rings exhibit cis arrangements at the ring junctions. One O atom of a tetrahydrofuran ring and the H atoms bound to the neighboring C atoms are disordered over two orientations with site-occupancy factors of 0.69 (1) and 0.31 (1). intramolecular O—H⋯O and C—H⋯O interactions stabilize the molecular conformation. In the crystal structure, intermolecular O—H⋯O and C—H⋯O interactions link the molecules into a three-dimensional network.
