“…These compounds include angustifoline and multiflorine, both present at an average level of 0.1% of the total alkaloids. The relative proportions of these two alkaloids is lower in comparison with those earlier reported for L. albus (angustifoline 3.8% and multiflorine 6.8% of the total alkaloids) [28]. The others alkaloids present in the 10 bitter ecotypes include α-isolupanine, nutalline, oxylupanine and 11, 12-dehydrolupanine, representing on average 0.4, 6.8, 4, 1.4% of total alkaloids, respectively.…”

“…The result is in agreement with the findings by Gross et al [17] which indicate lupanine to be the main alkaloid in L. mutabilis, accounting for more than 80% of total alkaloids. On the other hand, Rybiński et al [28] found that lupanine in L. albus represents 71.3% of the total alkaloids, this value being lower compared to the level in L. mutabilis. The concentration of lupanine in this study was higher than the content reported for seeds of L. mutabilis from Ecuador [29].…”

The evaluation of the level of alkaloids in edible Lupinus species is crucial from a food safety point of view. Debittering of lupin seeds has a long history; however, the control of the level of alkaloids after processing the seeds is typically only evaluated by changes in the bitter taste. The aim of this study was to evaluate the profile and residual levels of quinolizidine alkaloids (QA) in (Lupinus mutabilis Sweet) after aqueous debittering process. Samples from 10 ecotypes from different areas of Peru were analyzed before and after the process. Based on results obtained by gas chromatography and mass spectrometry, from eight alkaloids identified before the debittering process, only small amounts of lupanine (avg. 0.0012 g/100 g DM) and sparteine (avg. 0.0014 g/100 g DM) remained in the seeds after the debittering process, and no other alkaloids were identified. The aqueous debittering process reduced the content of alkaloids to levels far below the maximal level allowed by international regulations (≤ 0.2 g/kg DM).

“…However, the presence of secondary metabolites, which act as anti-nutritional compounds, in white lupin seeds limits its use. Lupinus albus wild varieties and landraces can accumulate up to 11% of their dry weight in the form of alkaloids, most of them belonging to the family of quinolizidine alkaloids (QA) (Rybiński et al, 2018). QA are notoriously bitter and toxic to both humans and farm animals, displaying both teratogenic and anti-cholinergic effects (Wink and Schimmer, 1999;Lourenço et al, 2002).…”

Alkaloids are part of a structurally diverse group of over 21,000 cyclic nitrogen-containing secondary metabolites that are found in over 20% of plant species. Lupinus albus are naturally containing quinolizidine alkaloid (QA) legumes, with wild accessions containing up to 11% of QA in seeds. Notwithstanding their clear advantages as a natural protecting system, lupin-breeding programs have selected against QA content without proper understanding of quinolizidine alkaloid biosynthetic pathway. This review summarizes the current status in this field, with focus on the utilization of natural mutations such as the one contained in pauper locus, and more recently the development of molecular markers, which along with the advent of sequencing technology, have facilitated the identification of candidate genes located in the pauper region. New insights for future research are provided, including the utilization of differentially expressed genes located on the pauper locus, as candidates for genome editing. Identification of the main genes involved in the biosynthesis of QA will enable precision breeding of low-alkaloid, high nutrition white lupin. This is important as plant based high quality protein for food and feed is an essential for sustainable agricultural productivity.
