Helichrysum bracteatum (family Compositae) seed oil contains a complex array of unusual fatty acids in addition to the usual palmitic, stearic, oleic, and linoleic acids. Its unusual constituents include 9.5% crepenynic acid; 14.0% epoxy acids, mainly coronaric; 4.4% cis,trans ‐hydroxy conjugated dienoic acids; and 7.2% of a previously unknown hydroxyacetylenic acid for which the name helenynolic acid is proposed. A method for determining helenynolic acid in the presence of hydroxy‐conjugated dienes is described.
