title: Occurrence of a novel cis,cis,cis-octadeca-3,9,12-trienoic (Z,Z,Z-octadeca-3,9,12-trienoic) acid in Chrysanthemum (tanacetum) zawadskii herb. (Compositae) seed oil.
abstract: A new octadecatrienoic acid (6.9%), found as a component of Chrysanthemum zawadskii Herb. (Asteraceae) seed oil, was shown to be the hitherto unknown cis,cis,cis-octadeca-3,9,12-trienoic acid. The oil also contained 8.6% of crepenynic acid in addition to the other common FA. The structures of the new unusual FA and other FA were confirmed by chromatographic (TLC, GC), spectroscopic (IR, UV, and NMR), and MS methods by using different chemical derivatizations (preparation of methyl ester, pyrrolidide, picolinyl esters, and dimethyloxazoline derivatives).
