Flavones are a type of plant secondary metabolite belonging to the flavonoid group. They are widely distributed in the plant kingdom and can be found in various parts of plants such as leaves, flowers, fruits, and seeds. Flavones play essential roles in plants, including pigmentation, UV protection, defense against pathogens, and attraction of pollinators.
Common dietary sources of flavones include fruits, vegetables, herbs, and beverages such as tea. Some specific plants known for containing flavones include:
Citrus fruits: Oranges, lemons, and grapefruits contain flavones such as hesperidin and naringin.
Parsley: Rich in apigenin, a well-known flavone.
Chamomile: Contains apigenin and other flavones.
Celery: Contains luteolin, another common flavone.
Peppers: Particularly bell peppers, which contain various flavones.
These are just a few examples, but flavones can be found in a wide variety of plant species, each with its own unique composition and concentration of flavones.
