چکیده
The mol-ecule of the title compound, C(16)H(12)O(4), is almost planar; the two meth-oxy groups are slightly out of the plane of the anthraquinone ring system, with C-C-O-C torsion angles of -6.25 (19) and -10.22 (19)°. In the crystal structure, the mol-ecules adopt a herringbone arrangement and form face-to-face slipped anti-parallel π-π stacking inter-actions along the b axis, with an inter-planar distance of 3.278 (2) Å.

The title compound, C18H24O2, was isolated from the leaves extract of Ficus carica L. The cyclo-hexane ring displays a chair conformation whereas the cyclo-hexa-1,4-diene ring adopts a flattened boat conformation with methyl C atoms at the prow and stern. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into supra-molecular chains propagated along the b-axis direction.
متن کاملControl of 1,4-Anthraquinone Crystal Growth
Quinones are widely found in nature, used in chemistry and medicine, and are just beginning to gain importance in materials engineering. In order to harvest their potential as an ordered or highly crystalline solid, their crystal formation processes need to be well investigated and controlled. We chose 1,4-anthraquinone, a commercially available type of quinone, as a model compound to study its...

Various intricate propellane derivatives and oxa-bowls have been synthesized via a ring-rearrangement metathesis (RRM) as a key step starting from readily accessible starting materials such as p-benzoquinone, 1,4-naphthoquinone and 1,4-anthraquinone.
متن کاملAnthrasesamone F from the seeds of black Sesamum indicum.
A new anthraquinone derivative, named anthrasesamone F, was isolated from the seeds of Sesamum indicum. Its structure was determined to be (Z)-6,7-dihydroxy-2-(6-hydroxy-4-methyl-3-pentenyl)anthraquinone on the basis of spectroscopic evidence.
متن کاملAntibacterial activity of Tabebuia impetiginosa Martius ex DC (Taheebo) against Helicobacter pylori.
The growth-inhibiting activity of Tabebuia impetiginosa Martius ex DC dried inner bark-derived constituents against Helicobacter pylori ATCC 43504 was examined using paper disc diffusion and minimum inhibitory concentration (MIC) bioassays. The activity of the isolated compounds was compared to that of the commercially available anti-Helicobacter pylori agents, amoxicillin, metronidazole, and t...
