Luteolin

491-70-3C15H10O6286.239 g/mol

A tetrahydroxyflavone in which the four hydroxy groups are located at positions 3', 4', 5 and 7. It is thought to play an important role in the human body as an antioxidant, a free radical scavenger, an anti-inflammatory agent and an immune system modulator as well as being active against several cancers. — ChEBI
