Seeds of oat (Avena sativa L.) were recently shown to contain significant quantities of a new hydroxy acid, (15R)-hydroxy-(9Z)-(12Z)-octadecadienoic acid (trivial name, avenoleic acid). In the present work, avenoleate was found to be mainly (63%) localized in the glycolipid fraction of oat seed lipids. Fractionation of the glycolipids by thin-layer chromatography and reversed-phase high-performance liquid chromatography revealed the presence of a main molecular species which accounted for 20… CONTINUE READING
