Flavone is an organic compound with the formula C

4OC
3H(Ph)O. A white solid, flavone is a derivative of chromone with a phenyl (Ph) substituent adjacent to the ether group. The compound is of little direct practical importance, but susbstituted derivatives, the flavones and flavonoids are a large class of nutritionally important natural products.[1] Flavone can be prepared in the laboratory by cyclization of 2-hydroxacetophenone.[2] Isomeric with flavone is isoflavone, where the phenyl group is adjacent to the ketone.
