Flavone (2-phenyl-4H-chromen-4-one) is the foundational compound of the flavone subclass of flavonoids, occurring naturally in various plant sources including passion flower, chamomile, and celery. It can be extracted from natural sources or synthesized through cyclization reactions.
Flavone and its derivatives exhibit a wide range of biological activities including antioxidant, anti-inflammatory, antimicrobial, and anticancer properties. The flavone backbone serves as the structural basis for numerous pharmacologically active flavonoids. Commercially, flavone is used as a supplement ingredient, pharmaceutical intermediate, and analytical standard in flavonoid research.
