The alkaloid anagyrine found in some Lupinus species has been shown to cause the teratogenic condition known as "crooked calf disease." A collection of western American lupines held by the Western Regional Plant Introduction Station was grown at Pullman, Washington, to determine the extent and levels of anagyrine in these accessions. The plants were field grown on Tucannon soil, a fine-silty, mixed, mesic pachic Haploxerolls. Anagyrine determinations were made by gas/liquid chromatography. Accessions that were positive for anagyrine in June 1977 were resampled and verified in 1978. Anagyrine and total alkaloids were higher in April and markedly diminished by July. Seeds were higher in total alkaloids and anagyrine, when present, than was mature vegetation.
