Luteolin is a flavone, a type of flavonoid, with a yellow crystalline appearance.

Luteolin is the main yellow dye from the Reseda luteola plant, used for dyeing since at least the first millennium B.C. Luteolin was first isolated in pure form, and was named in 1829 by the French chemist, Michel Eugène Chevreul.

Luteolin is a phytochemical present in leaves, bark, flower blossoms, pollens, various vegetables, and herbs.
