aurone
Sign in to saveAn 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.

==Aurone derivatives== thumb|right|200px|Skeletal structure of an (Z)-aurone with numbering scheme used for nomenclature of derivatives Aurone forms the core for a family of derivatives which are known collectively as aurones. Aurones are plant flavonoids that provide yellow color to the flowers of some popular ornamental plants, such as snapdragon and cosmos. Aurones including 4'-chloro-2-hydroxyaurone (C15H11O3Cl) and 4'-chloroaurone (C15H9O2Cl) can also be found in the brown alga Spatoglossum variabile.
