The seed oil of Caltha palustris L. yields two unusual polyunsaturated components, all‐ cis ‐5,11,14‐eicosatrienoic acid (23%) and all‐ cis ‐5,11,14,17‐eicosatetraenoic acid (1%). The C 18 monoene fraction (26%) is a mixture of cis ‐5‐ and cis ‐9‐octadecenoic acids (2∶1). The C 20 monoene fraction (12%) is a mixture of cis ‐11‐ and cis ‐5‐isomers (3∶1).
