description The title compound, C(26)H(24)O(5), was isolated from calophyllum inophyllum seeds. In the mol­ecule, the phenyl and 2-methyl­but-2-enoyl groups are almost orthogonal to the chromene fragment [C—C—C—C torsion angles = 81.4 (3) and −90.1 (2)°, respectively]. In the crystal packing, centrosymmetrically related mol­ecules are linked by C—H⋯O contacts into dimers, which are connected via further C—H⋯O inter­actions into a double chain along [010].
