L. hintonii C. P. Smith grows in the Central Highland forests of Mexico at altitudes between 2800 m to 3200 m above see level. Members of the genus Lupinus produce quinolizidine alkaloids as main chemical defensive compounds against herbivores. Surprisingly alkaloid profiles are rather constant
Quinolizidine alkaloids (QAs) are toxic secondary metabolites of Lupinus plants. This study reports the simultaneous quantification of five alkaloids from Lupinus angustifolius L. and its processed foods by ultraperformance liquid chromatography with electrospray ionization mass
The bitter and sweet forms of a plant species differing with alkaloid contents may provide a model system for investigation of alkaloid biosynthesis at a molecular level. The pattern and concentration of quinolizidine alkaloids were determined by capillary GC-MS in bitter and sweet plants of Lupinus
The intake of lupin-based foods could imply the exposure of consumers to quinolizidine alkaloids. The objectives of this study were to assess the genetic variation among and within 11 geographic regions of Lupinus albus ecotypes, verify the quinolizidine alkaloids amount of alkaloid-poor L. albus
In recent years there has been growing interest in replacing (genetically modified) soya by lupin. Lupin seeds, flours and lupin containing food have been analyzed in order to assess the relevance of a potential health hazard given by mycotoxins and/or naturally occurring alkaloids. Since not all
Lupin seeds are important for animal and human nutrition. However, they may contain toxic quinolizidine alkaloids (QA). Analytical methods for a reliable alkaloid determination are therefore of importance. Here the presented study reports on the first CE method for the analysis of QA in Lupinus
