Marshallia cacspitosa Nutt. seed oil (family Compositae) contains 44% cis ‐11‐eicosenoic acid, and is the first oil from the Compositae found to contain a high proportion of C 20 ‐monoenoic acid. Seed oils of Alyssum maritimum (L.) Lam. and of Selenia grandis Martin (family Cruciferae) contain 42 and 58% of the same acid, respectively. The C 20 acids from all three oils were obtained in nearly pure form by fractional distillation of the mixed methyl esters by means of a spinning band column. Permanganate‐periodate oxidation of the purified methyl esters yielded predominantly nonanoic and undecanedioic acids.
