Abstract Weak interactive forces play an important role to form unit crystals of chemical components. So, it is felt pertinent to look into this phenomenon in naturally occurring chemical entities. Since flavonoids are one of the main groups of natural products of biological importance, it is important to find the role of these forces in natural flavonoids. But X-ray crystallographic study is not common for natural flavonoids. Hence, detailed X-ray crystallographic analysis obtained from the different studies on some flavonoid molecules reported from 2005 to 2017 is being considered. An analysis of hydrogen bond, C-H…O, C-H… and  interactions observed in the reported structures indicate that such weak interactive forces play a dessisive role in assembling the molecules into an organized supramolecular structure. This review cites 58 references.
