Swertisin dihydrate
The molecular structure of the 6-C-glucopyranosyl-7-O-methylapigenin dihydrate is discussed. The basal plane of the pyranosyl ring of the glucose moiety is found to be perpendicular to the benzopyran ring system. It is observed that the flavone skeletons are stacked along the a axis, forming layers parallel to (001). The glucose groups and water molecules of crystallization are connected via O-H···O hydrogen bonds.

C-glucosyl flavones from the seeds of ziziphus jujuba var. spinosa
A new C-glucosyl flavone, 6'-vanilloylspinosin (1), was isolated from the seeds of Ziziphus jujuba var. spinosa, together with three known C-glucosyl flavones, spinosin (2), 6'-feruloylspinosin (3), and isospinosin (4). The structure of 1 was elucidated by spectral methods (1D NMR, ESI-MS, HR-MS, 2D NMR).
