Abstract

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.

摘要

从刺金雀花的酸性提取物中分离出四种新的喹诺里西啶生物碱，即刺金雀花碱A（1）、B（2）、C（3）和D（4），并通过光谱方法对其进行了表征，同时还鉴定出了（-）-金雀花碱、（-）-N-甲基金雀花碱和（-）-臭豆碱。本文简要讨论了这些新生物碱的推测生物合成起源。
