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 also occurs in the herb Marrubium vulgare (White horehound), where it is conjectured to have an anti-fungal role. It was found to stimulate lipid accumulation by adipocytes in vitro.[7]

Tariric acid is biosynthesised from petroselinic acid; both fatty acids have been found together in Picramnia and Alvaradoa species.[8][9] The occurrence of tariric acid as the major fatty acid is typical for the Picramniaceae.[10]

Production and chemical behavior

Tariric acid can be synthesised from commercially available petroselinic acid.[11]

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.[12]
