Pinobanksin is an antioxidant bioflavonoid (specifically a dihydroflavonol, a category of flavonol) that inhibits peroxidation of low density lipoprotein and it has electron donor properties reducing alpha-tocopherol radicals. It is present in sunflower honey.[1]
Pinobanksin is biosynthesized from pinocembrin.
