Luteic acid is a natural phenol found in numerous fruits. It is a monolactonized tergalloyl group. Maximilian Nierenstein showed in 1945 that luteic acid was a molecule present in the myrobalanitannin, a tannin found in the fruit of Terminalia chebula and is an intermediary compound in the synthesis of ellagic acid.[1] It can form from hexahydroxydiphenic acid. It is also present in the structure of the tannins alnusiin and bicornin.[2]
