S. Yao and W. Qing

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-HO hydrogen bonds. A further intermolecular O-HO hydrogen bond leads to chains along [010] in the crystal structure.
