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