5-{(2S,3R,4S,5S,6R)-3,4-Dihydroxy-6-hydroxymethyl-3-[(2S,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyltetrahydropyran-2-yloxy]tetrahydropyran-2-yloxy}-7-hydroxy-2-(4-hydroxyphenyl)chromen-4-one monohydrate
Abstract
In the title compound, C27H30O14·H2O, the hydroxyphenyl ring makes a dihedral angle of 20.05 (11)° with the chromenone ring system. The crystal structure is stabilized by intra- and intermolecular O—H...O hydrogen bonds. The absolute configuration was assigned on the basis of an analagous structure.
