✦ Synopsis

Angustifoline (Cx4HesONe) is an alkaloid that has been isolated from three plants: Lupinus anmstifolius, a L _. polmhFllus and &. albua. It is a monoacidic bass containing a laetamic carbonyl and a double bond. Both functions are indicated in the infrared spectrum and their presence,oonfirmed by catalytic hydrogenation which in neutral aolution gives dihydroangustifoline, Cx,HerONe, and in acid solution produces dihydrodesoxyangustifoline, C14HeeNe, a diacidic base.'
