Obtusilic acid is a linear fatty acid composed of 10 carbon atoms, with one double bond[1] in the position 4=5 in cis-configuration. This is an omega-6 acid of little nutritional interest with abbreviated notation 10:1 (n-6).[2][3]
The acid was initially isolated in the seed oil of Lindera obtusiloba, from which it takes its common name, in 1937 by the Japanese scientist Toyama and confirmed in the same year by Saburo Komori and Sei-ichi Ueno.[4][5]
Natural occurrence
Lindera obtusiloba oil, Tohaku in Korean, which contains about 4% obtusilic acid, was an oil that Koreans applied to their hair.[6] Obtusilic acid has been isolated from only a few other plants of the family Lauraceae: Lindera praecox (≈5%), Litsea auriculata (≈4%), Lindera citriodora (≈3%).
