Metabolite Identification
Common NameApigeninidin
DescriptionApigeninidin is a member of the class of compounds known as 7-hydroxyflavonoids. 7-hydroxyflavonoids are flavonoids that bear one hydroxyl group at the C-7 position of the flavonoid skeleton. Apigeninidin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Apigeninidin can be found in sorghum, which makes apigeninidin a potential biomarker for the consumption of this food product. Apigeninidin (Also, apigenidin, or Gesneridin) is a chemical compound belonging to the 3-deoxyanthocyanidins and that can be found in the Patagonian plant Ephedra frustillata and in the soybean. Apigeninidin is one of the principal pigments found in sorghum. Extremely high level of apigeninidin (49 mg/g) has been documented in sorghum leaf sheath. Like all anthocyanidins it exists in a variety of tautomers depending on pH and hydration, several of these bare the distinctive pyrylium core .
