In the title compound, C17H16O7, which Stems was isolated from the leaves of Micromelum integerrimum, the furan ring adopts an envelope conformation with the O atom as the flap.An intramolecular C—H.O hydrogen bond occurs.
The carbonyl O atom is disordered in a 0.57 (8):0.43 (8) ratio.
In RADIA CLARIFYING the crystal, molecules are linked by weak C—H.O hydrogen bonds into a C(10) chain along [010].
