The synthesis of cis ‐9,10‐epoxyoctadecanoic acid by tissue slices of wheat plants infected with Puccinia graminis tritici (Wheat stem rust) has been investigated further. Synthetic methyl cis ‐9,10‐epoxyoctadecanoate and the same ester isolated from incubation in an atmosphere containing 18 O 2 , or a medium containing H 2 18 O, were analyzed by mass spectrometry. These analyses revealed that molecular oxygen was incorporated into the oxirane ring of cis ‐9,10‐epoxyoctadecanoic acid.
