Tariric acid is an acetylenic fatty acid that can be found in the tallow-wood tree, Ximenia americana.^[1]

Léon-Albert Arnaud (1853–1915) was the first scientist to describe the chemical make-up of tariric acid, an extraction from the glucoside of the "tariri plant" found in Guatemala.^[2]

Occurrence

Tariric acid has been found in several oils and fats of plant origin. It was first isolated in 1892 from the seed oil of a species of Picramnia.^[3] It appears in Picramnia camboita from Brazil,^[4] Picramnia carpinterae from Guatemala,^[5] and Picramnia lindeniana from Mexico.^[6]

Tariric acid is biosynthesised from petroselinic acid; both fatty acids have been found together in Picramnia and Alvaradoa species.^[7][8] The occurrence of tariric acid as the major fatty acid is typical for the Picramniaceae.^[9]

Production and chemical behavior

Tariric acid can be synthesised from commercially available petroselinic acid.^[10]

In chemical analysis, tariric acid can be separated from other fatty acids by gas chromatography of methyl esters; additionally, a separation of unsaturated fatty acids is possible by argentation thin-layer chromatography.^[11]
