Luteolin is a flavone, a type of flavonoid, with a yellow crystalline appearance. Luteolin can function as either an antioxidant or a pro-oxidant and plants rich in luteolin have been used in Chinese traditional medicine.
Luteolin is the principal yellow dye compound that is obtained from the plant Reseda luteola, which has been used as a source of the dye since at least the first millennium B.C. Luteolin was first isolated in pure form, and named, in 1829 by the French chemist Michel Eugène Chevreul. The luteolin empirical formula was determined by the Austrian chemists Heinrich Hlasiwetz and Leopold Pfaundler in 1864. In 1896, the English chemist Arthur George Perkin proposed the correct structure for luteolin. Perkin's proposed structure for luteolin was confirmed in 1900 when the Polish-Swiss chemist Stanislaw Kostanecki (1860–1910) and his students A. Różycki and J. Tambor synthesized luteolin.

1.Luteolin is an active inhibitor of different hyaluronidases, which modify hyaluronic acid. Hyaluronic acid, a heteropolysaccharide, is one the polymers that accounts for the toughness and flexibility of cartilage and tendon.
2. Luteolin exhibits spasmolytic effects: Luteolin significantly antagonized acetylcholine- and histamine-induced contraction of smooth muscle in the guinea pig model of modified air overflow and showed strong anti-histamine properties.
3. Luteolin displays anti-leishmanial activity.
4. Luteolin displays strong antinociceptive (against pain originating from peripheral nerves) action in mice. This is in accordance with the fact that Luteolin is an active principle of Brazilian plant Wedelia paludosa, traditionally used against the variety of disorders, including painful conditions.
