In the recent research, plant derived natural compound become the hot point of study for the safe and effective drug. Flavonoids are one of the important secondary plant metabolites. Flavan and flavanone are the major class of flavonoids, important biologically active natural compounds. So search of new natural flavans and flavanones, having radical scavenging activity is of major attention to the chemists now. The present resume describes 41 new examples of naturally occurring flavans and flavanones having antioxidant potential reported during the period of 2005 to 2017. These flavan and flavanones are found either as aglycones or as glycosides, comprising flavans, flavanones, flavanols, isoflavans and isoflavanones and miscellaneous flavanones (homoisoflavan and bi-flavanones). The main topics addressed are source, structure, antioxidant activity. The review cites 66 references.
