trans ‐10‐ trans ‐12‐Octadecadienoic acid was found to be a component of the glyceride oil of the seeds of Chilopsis linearis (Cav.) Sweet. It was isolated by fractional crystallization of the acids at low temperatures. Identification was made by absorption spectra, by the adduct with maleci anhydride, and by identification of degralative products. The conjugated triene of the oil was also isolated and identified as trans ‐9‐ trans ‐11‐ cis ‐13octadecatrienoic acid. in two samples of seed, the diene acid constituted about 9% of the oil and the triene acid 18% and 25%.
