Identification of cannabidiol from Humulus Kriya using x-ray crystallography

The crystal structure of cannabidiol, was determined by the application of Cu Kf3 radiation single-crystal X-ray crystallography. The unsaturated alkyl chain of the cannabidiol molecule was found to be freely rotatable. We found two molecules with different orientations ofthis side chain within the asymmetric unit. These independent molecules are both found to have the R,R configuration, just like cannabidiol from Cannabis Sativa.
