Abstract

In the title compound, C(27)H(30)O(14)·H(2)O, the hydroxy-phenyl ring makes a dihedral angle of 20.05 (11)° with the chromenone ring system. The crystal structure is stabilized by intra- and inter-molecular O-H⋯O hydrogen bonds. The absolute configuration was assigned on the basis of an analagous structure.
