New quinolizidine alkaloids from Ulex jussiaei.
From an acidic extract of Ulex jussiaei four new quinolizidine alkaloids, jussiaeiines A (1), B (2), C (3), and D (4), were isolated and characterized by spectroscopic methods together with (-)-cytisine, (-)-N-methylcytisine, and (-)-anagyrine. The proposed biosynthetic origin of these new alkaloids is briefly discussed.
