Studies on Argentine Plants. XVIII. Multiflorine, the Alkaloid from Lupinus multiflorus Lam

Abstract

From the seeds of Lupinus multiflorus Lam., a plant growing in north-eastern Argentina, an alkaloid C₁₅H₂₂ON₂ has been isolated and named multiflorine. It is identical with the base LV-1 isolated in Australia from the seeds of Lupinus digitatus Forsk. by Crow and Riggs (1955). Most of its reactions and properties are explained by accepting a 2-dehydro-4-oxosparteine structure for the alkaloid.
