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. 
Chemotaxonomy of Portuguese Ulex: quinolizidine alkaloids as taxonomical markers.
TLDR
Six species of Portuguese Ulex L. in a total of nineteen populations were studied by GC-EIMS as to their content in quinolizidine alkaloids, which allowed the definition of five chemotypes and the recognition of hybrids. Expand

TLDR
The present survey covers the literature from mid-1999 to the end of 2013; and in addition to aspects of the isolation, characterization, and biological activity of the alkaloids, much emphasis is placed on their total synthesis. Expand

Efecto de extractos de Ulex europaeus L. en la producción de biomasa de plántulas de ají (Capsicum annuum L.), en condiciones de laboratorio
TLDR
In high doses of Hm extract, an increase in GM was observed compared to control; but in DM, it was not; therefore, feasibility of using U. europaeus extracts to increase GM and DM production in C. annuum can be ensured. Expand
Effect of Ulex europaeus L. extracts on polyphenol concentration in Capsicum annuum L. and Lactuca sativa L.
TLDR
Under laboratory conditions the polyphenol content rose with increasing extract doses in both species, but this tendency was not observed in the greenhouse, which opens up the possibility of cultivating species with higher antioxidant contents using natural products. Expand
