organic compounds
The title compound, C17H16O5, was isolated from the plant Lindera poliantha. The cyclopentenedione and phenyl rings are connected by the central C3O fragment, which makes dihedral angles with these rings of 7.10 (6) and 16.24 (10)°, respectively.
organic compounds
The title compound, 2C14H13NO4·3H2O, was isolated from the plant Acronychia pendunculata. The asymmetric unit consists of two quinoline molecules and three water molecules of crystallization. Intra- and intermolecular hydrogen bonds are highly effective in forming infinite chains parallel to the b axis, thereby stabilizing the crystal structure.
