description In the title coumarin compound (systematic name: 6-butyryl-5-hy­droxy-8,8-dimethyl-4-phenyl-2H,8H-benzo[1,2-b;3,4-b′]dipyran-2-one), C(24)H(22)O(5), also known as mammea A/AC cyclo D, the chromene and pyran rings are almost coplanar with a maximum deviation from the mean plane of 0.295 (2) Å. The attached phenyl group is inclined at 53.49 (8)° with respect to the chromene ring. The mol­ecular structure is stabilized by an intra­molecular O—H⋯O hydrogen bond. In the crystal, mol­ecules are linked into sheets parallel to (101) by inter­molecular C—H⋯O hydrogen bonds. Adjacent sheets are sustained by inter­molecular C—H⋯π and π–π [centroid–centroid distance = 4.471 (2) Å] inter­actions.
