Lupinine could not be detected in six-weeks-old Thermopsis caloriliniana and Lupinus angustifolius by pulse feeding of ^(14)CO₂ and using the G. L. C. -continuous combustion flow counting system, T.L.C. and some spectroscopic methods. Lupanine appears to be the first labeled alkaloid in T. caroliniana and L. angustifolius. Δ^5-Dehydrolupanine was not detected in L. angustifolius but in T. carloriniana. No evidence was obtained for the formation of lupinine, casting on its role in the formation of lupin alkaloids.
