5,3′-Dihydroxy-7,4′-dimethoxyflavanone from Artemisia sphaerocephala Kraschen

Abstract

The title compound, C17H16O6, was isolated from the Chinese Tibetan medicinal plant Artemisia sphaerocephala Kraschen. The molecular conformation is consolidated by two intramolecular O—H...O hydrogen bonds. A further intermolecular O—H...O hydrogen bond leads to chains along [010] in the crystal structure.
