The seed oil ofCaltha 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 C18 monoene fraction (26%) is a mixture ofcis-5- andcis-9-octadecenoic acids (2∶1). The C20 monoene fraction (12%) is a mixture ofcis-11- andcis-5-isomers (3∶1).
