Chemical Information
FooDB NameFlavones
DescriptionFlavone, also known as 2-phenylchromone, belongs to the class of organic compounds known as flavones. These are flavonoids with a structure based on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one). Thus, flavone is considered to be a flavonoid. Flavone is a bitter tasting compound. Flavone has been detected, but not quantified in, several different foods, such as dills (Anethum graveolens), feijoas (Feijoa sellowiana), pomegranates (Punica granatum), and rosemaries (Rosmarinus officinalis). This could make flavone a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Flavone.
