From the genus Lupinus more than 400 species ate known, but only four have been domesticated and are of agronomic and commercial interest Lupinus albus (white lupin), Lupinus angustifolius (narrow leaf or blue lupin), Lupinus luteus (yellow lupin), and Lupinus mutabilis (Andean lupin).

Quinolizidine alkaloids occur in seeds (beans) of certain species of lupines Lupinus spp., Fabaceae), including domesticated varieties. In Europe, Africa and America, lupines have been used as valuable pulses for human nutrition and feeding livestock from ancient times. Native species growing in south-western Europe are white lupine (L. albus), blue (narrow leaf) lupine (I. angustifolius) and yellow lupine (L. luteus). Yellow lupine is currently grown in Western Australia, particularly for feed, and for human nutrition in many countries of Asia. Beans of pearl (Andean) lupine (I. mutabilis), called tarhui or tarwi, are eaten as pulses by South American Indians of the Andes region and also used as an oil crop (mainly in Chile).
