An unusual series of monoenoic fatty acids constitutes about 85% of the total acids in seed oil from Thunbergia alata . The major component in the oil, cis ‐6‐hexadecenoic acid (82%), is accompanied by the homologous 4‐tetradecenoic (ca. 0.2%) and 8‐octadecenoic (1.8%) acids. Another homologous series is represented by 5‐tetradecenoic (ca. 0.2%), 7‐hexadecenoic (1.8%) and the familiar 9‐octadecenoic (4.4%) acids. Traces (<0.1%) of three other acids, 6‐tetradecenoic and 10‐ and 11‐octadecenoic, are also present along with palmitic (5.8%), stearic (0.6%) and linoleic (2.2%) acids. Some of the monoenoic acids have not previously been known to occur in seed oils.
