Apigenin (4′,5,7-trihydroxyflavone), found in many plants, is a flavone compound that is the aglycone of several naturally occurring glycosides. It is a yellow crystalline solid that has been used to dye wool.

Apigenin is abundant in parsley, celery, celeriac, and chamomile flowers. It occurs in many fruits and vegetables, with the highest concentrations in dried and fresh parsley.
