Apigeninidin (Also, apigenidin,[1] or Gesneridin) is a chemical compound belonging to the 3-deoxyanthocyanidins and that can be found in the Patagonian plant Ephedra frustillata[2] and in the soybean.[3] Apigeninidin is one of the principal pigments found in sorghum.[4] Extremely high level of apigeninidin (49 mg/g) has been documented in sorghum leaf sheath.[5] Like all anthocyanidins it exists in a variety of tautomers depending on pH and hydration, several of these bare the distinctive pyrylium core.[6]
