Apigenin is a natural flavone flavonoid abundant in parsley, chamomile tea, celery, and various fruits and vegetables. It features a 2-phenylchromen-4-one backbone with hydroxyl groups at the 4', 5, and 7 positions that confer antioxidant and anti-inflammatory bioactivity. Apigenin modulates GABA-A receptors, inhibits CYP enzymes, and influences pathways regulating cell proliferation and apoptosis. Dietary intake is associated with potential neuroprotective and chemopreventive effects. The compound is poorly soluble in cold water but shows improved solubility in organic solvents and hot ethanol. It is stable under normal food processing conditions and contributes to the color and health-promoting properties of plant-based foods.
