Luteolin is a flavone, a type of flavonoid, with a yellow crystalline appearance.[1]
Natural occurrences[edit]
Luteolin is most often found in leaves, but it is also seen in rinds, barks, clover blossom, and ragweed pollen.[1] It has also been isolated from the aromatic flowering plant, Salvia tomentosa in the mint family, Lamiaceae.[2]
Dietary sources include celery, broccoli, green pepper, parsley, thyme, dandelion, perilla, chamomile tea, carrots, olive oil, peppermint, rosemary, navel oranges, and oregano.[3][4] It can also be found in the seeds of the palm Aiphanes aculeata.[5]
