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.

Seed Specific Expression

Seed-specific expression in Arabidopsis thaliana of oleate hydroxylase enzymes from castor bean and Lesquerella fendleri resulted in the accumulation of hydroxy fatty acids in the seed oil. By using various Arabidopsis mutant lines it was shown that the endoplasmic reticulum (ER) n–-3 desaturase (FAD3) and the FAE1 condensing enzyme are involved in the synthesis of polyunsaturated and very-long-chain hydroxy fatty acids, respectively. In Arabidopsis plants with an active ER Δ12-oleate desaturase the presence of hydroxy fatty acids corresponded to an increase in the levels of 18:1 and a decrease in 18:2 levels. Expression in yeast indicates that the castor hydroxylase also has a low level of desaturase activity.
