Abstract
The title compound, C16H12O5, was isolated from Morinda officinalis How. The anthraquinone ring system is almost planar, the dihedral angle between the two benzene rings being 1.12 (4)°. In the crystal structure, O—H⋯O and C—H⋯O hydrogen bonds link the moleculesin the crystallographic a-axis direction. Weak π–π stacking interactions [centroid–centroid distance between symmetry-related benzene rings of 3.699 (4) Å] are also present.
Highlights
The title compound, C16H12O5, was isolated from Morinda officinalis How
Anthraquinone derivatives extracted from the roots of Morinda officinalis How. have been used to support the entire body treating a wide range of symptoms, including poor digestion, high blood pressure and immune deficiencies in China since ancient times
One component found in Morinda officinalis How., 1,2dimethoxy-3-hydroxyanthraquinone, exhibits a variety of potent biological effects such as antiviral and antimicrobial activities (Ali et al, 2000), antioxidant activity (Jia et al, 2007) and cyototoxic activity (Wu et al, 2003)
