An aurone is a heterocyclic chemical compound, which is a type of flavonoid. There are two isomers of the molecule, with (E)- and (Z)-configurations. The molecule contains a benzofuran element associated with a benzylidene linked in position 2. In aurone, a chalcone-like group is closed into a 5-membered ring instead of the 6-membered ring more typical of flavonoids.
