The seed oil of Tragopogonporrifolius L. was found to contain about 4% of conjugated diene hydroxy fatty acids, identified as 9-hydroxy-10,12- and 13-hydroxy-9,11-octadecadienoic acids. On dehydration, the products were 8,10,12- and 9,11,13-octadecatrienoic acids. The diene acids were cis,trans or trans,cis and the triene acids were judged to be all-trans.The conjugated triene acid of Calendulaofficinalis L. seed oil was isolated and identified as trans,8:trans, 10:cis,12-octadecatrienoic acid by spectral analysis, by the structure of the maleic anhydride adduct, and by identification of degradation products. All-trans-8,10,12-octadecatrienoic acid was found to react with maleic anhydride at both the 8,11 and 10,13 positions.
