The Alkaloids of Lupinus varius L. I. Isolation of the Alkaloids

Abstract

The seeds of Lupinus varius L. (Leguminosae), used in parts of Western Australia as sheep fodder, contain an alkaloid LV-1, C₁₅H₂₂ON₂ (0.20 per cent.), (+)-epilupinine (0.13 per cent.), (+)-epilupinine-N-oxide (0.94 per cent.), and traces of an alkaloid LV-2. The N-oxide represents the first reported natural occurrence of such a compound in the lupinine group.
