Common NameTangeritin
DescriptionTangeritin, also known as ponkanetin or tangeretin (6ci), belongs to the class of organic compounds known as 8-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, tangeritin is considered to be a flavonoid lipid molecule. A Tangeritin flavone with methoxy groups at positions 4', 5, 6 , 7 and 8. Tangeritin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Tangeritin is a bitter tasting compound. Outside of the human body, Tangeritin is found, on average, in the highest concentration within sweet oranges. Tangeritin has also been detected, but not quantified in, several different foods, such as sweet bay, fruits, grapefruits, parsley, and citrus. Tangeritin is found in Artemisia mesatlantica, Aspergillus niger, Ballota nigra, Citrus aurantium , Citrus deliciosa, Citrus depressa, Citrus grandis var.tomentosa , Citrus hassaku, Citrus jambhiri Lush., Fortunella japonica , Citrus maxima, Citrus sinensis, Citrus tangerina , Citrus unshiu, Clematis hexapetala, Ficus beecheyana, Ficus erecta, Fortunella margaria, Mandarina satsuma, Oxalis pes-caprae, Syzygium jambos and Xinhui citrus. Tangeritin was first documented in 2012 (PMID: 22476082). This could make tangeritin a potential biomarker for the consumption of these foods.
