Interpretive Summary: Atraphaxis, which belongs to the Polygonaceae family, comprises about 18 species spread throughout Asia, northern Africa, and southern Europe. The aerial parts of Atraphaxis laetevirens were the subject of a natural compound investigation. Recently, anthraquinones and a naphthalene derivative have been isolated from A. laetevirens as antibacterial compounds, whereas their chemotaxonomic properties were not discussed. In addition, there are no other phytochemical studies on A. laetevirens and no distinguishing chemotaxonomic markers in the genus Atraphaxis. These results suggested that A. laetevirens might be chemotaxonomically associated with A. pyrifolia.

Technical Abstract: The genus Atraphaxis comprises about 18 species spread throughout Asia, northern Africa, and southern Europe. The aerial parts of Atraphaxis laetevirens were the subject of a natural compound investigation. Recently, anthraquinones and a naphthalene derivative have been isolated from A. laetevirens as antibacterial compounds, whereas their chemotaxonomic properties were not discussed. In addition, there are no other phytochemical studies on A. laetevirens and no distinguishing chemotaxonomic markers in the genus Atraphaxis. This is the first report on the presence of 8-O-acetyl-7-O-methylgossypetin in a natural source and its detailed NMR chemical shift data is reported here. 8-O-acetyl-7-O-methylgossypetin may be a more useful and distinguishing compound for chemotaxonomic studies of the genus Atraphaxis than other flavanoids.
