CATEGORY

Luteolin—chemically designated as 3′,4′,5,7-tetrahydroxyflavone—is a natural flavonoid compound widely distributed throughout the natural world. This substance was first isolated and extracted in 1828 by the French chemists Pelletier and Caventou from *Reseda luteola*, a plant belonging to the Resedaceae family, from which it derives its name. Luteolin is extremely widespread within the plant kingdom; it is commonly found in the leaves, flowers, and fruits of plants such as honeysuckle, chrysanthemum, perilla, celery, and chili peppers, serving as a key active ingredient in numerous traditional Chinese medicinal herbs and everyday vegetables.

Function

Luteolin and its formulations are utilized as adjunctive therapies for a wide range of medical conditions. In the context of the respiratory system, they are frequently employed to suppress coughing, facilitate expectoration, and alleviate asthma symptoms.

Regarding the digestive system, they serve anti-inflammatory and hepatoprotective functions; in dermatology, they are used to treat allergic dermatitis and various inflammatory skin diseases. Furthermore, luteolin stands as one of the primary active ingredients in numerous complex Traditional Chinese Medicine formulations—such as *Duyiwei* Capsules and *Maishu* Capsules.

In the food industry, luteolin is utilized as a natural colorant and antioxidant, incorporated into beverages and health supplements to enhance their functional properties.

Within the cosmetics sector, leveraging its antioxidant and anti-inflammatory attributes, luteolin is incorporated into skincare products designed for anti-aging, skin brightening, and soothing repair, thereby aiding in the protection of the skin against damage induced by ultraviolet radiation.
