| Abstract: | The title compound, 6‐C‐glucopyranosyl‐7‐O‐methylapigenin dihydrate, C22H22O10·2H2O, is a natural C‐glucosylflavone. The flavone skeleton is almost planar, the dihedral angle between the pyran moiety and the 4‐hydroxyphenyl ring being 9.8 (3)°. The basal plane of the pyranosyl ring of the glucose moiety is almost perpendicular to the benzopyran ring system. The flavone skeletons are stacked along the a axis, forming layers parallel to (001). Between these hydrophobic layers, the glucose groups and water molecules of crystallization are connected via O—H⋯O hydrogen bonds, forming hydrophilic layers. |
