Luteolin is a naturally occurring flavone flavonoid found in numerous plants including celery, parsley, thyme, and chamomile. It possesses a 15-carbon flavone backbone with four hydroxyl groups conferring strong antioxidant and anti-inflammatory activities. Research indicates potential benefits in modulating oxidative stress, inhibiting inflammatory cytokines, and exhibiting neuroprotective and anticancer properties through pathways such as NF-κB and Nrf2. It appears as a yellow crystalline solid and is studied for applications in functional foods and nutraceuticals due to its presence in common dietary sources.
