Abstract Seed oil of Xeranthemum annuum (family Compositae) contains a number of unusual fatty acids in addition to palmitic, stearic, oleic, linoleic and linolenic. These acids include cis ‐5, cis ‐9, cis ‐12‐octadecatrienoic, 5%; cis ‐9‐ l ,10‐ l ‐epoxyoctadecanoic, 3%; cis ‐9‐ l ,10‐ l ‐epoxy‐ cis ‐12‐octadecenoic (coronaric), 8%; and cis ‐12‐ d ,13‐ d ‐epoxy‐ cis ‐9‐octadecenoic (vernolic), 2%; as well as a mixture of two hydroxy acids, 11%. The absolute configurations of the two 9,10‐epoxy acids are established for the first time.
