title: 5,3'-Dihydr-oxy-7,4'-dimethoxy-flavanone from Artemisia sphaerocephala Kraschen.
abstract: The title compound, C(17)H(16)O(6), was isolated from the Chinese Tibetan medicinal plant Artemisia sphaerocephala Kraschen. The mol-ecular conformation is consolidated by two intra-molecular O-H⋯O hydrogen bonds. A further inter-molecular O-H⋯O hydrogen bond leads to chains along [010] in the crystal structure.
