Aurones are chemical compounds belonging to polyphenols. Aurones are plant flavonoids that provide yellow color to the flowers of some popular ornamental plants, such as snapdragon and cosmos.
In aurones, chalcone closes into a 5 instead of the 6 atoms ring (C ring) more typical of flavonoids.
Most of aurones are in Z configuration but there are also some in E configuration ([[(E)-3�-O-�-d-glucopyranosyl- 4,5,6,4�-tetrahydroxy-7,2�-dimethoxyaurone]]) found in Gomphrena agrestis.
