摘要
This study describes the analysis of five quinolizidine alkaloids (QA), i.e. 13-OH-lupanine, lupanine, lupinine, angustifoline and sparteine in 30 samples of lupine flours, lupine seeds and derived products collected 2019-2021 on the German retail market. QA occur as secondary metabolites in plants of lupine species. Certain QA are of toxicological relevance. The analytical determination performed by LC-MS/MS revealed some samples with high QA concentrations (up to 21,000 mg/kg), particularly in bitter lupine seeds. As those concentrations would result in substantial exceedances of the maximum tolerable intake values proposed by health authorities, they must be considered as a health concern.
