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] References1. ^{{Cite journal | last1 = Nierenstein | first1 = M. | last2 = Potter | first2 = J. | title = The distribution of myrobalanitannin | journal = The Biochemical Journal | volume = 39 | issue = 5 | pages = 390–392 | year = 1945 | pmid = 16747927| pmc = 1258254 | doi=10.1042/bj0390390}} 2. ^Structures of alnusiin and bicornin, new hydrolyzable tannins having a monolactonized tergalloyl group.
