The crystal and molecular structures of hancokinol and hancolupenone from Cynanchum hancokianum have been determined by X-ray analysis. In the case of hancokinol, among four molecules related on a 4-fold rotation axis, hydrogen bondings between the hydroxyl groups of neighboring molecules are observed.
