✦ Synopsis

In this study, the proximal chemical analysis and contents of antinutritional factors (lectins, antitrypsin activity, cyanogenic glycosides, alkaloids, phytates and -galactosides) of ¸upinus exaltatus, ¸. re-exus, and ¸. mexicanus seeds were determined. The seeds of these lupins comprised 384.1, 388.0, 367.0 g/kg protein, which contained all the essential amino acids for human beings except glutamine and asparagine in their seed protein. Only ¸. exaltatus was free from lectins. Trypsin inhibitor concentrations ranged from 1.12 to 2.05 TIU/mg. Cyanogenic glycosides were present at low concentrations in the studied lupins. Total alkaloid content ranged from 14.0 to 44.0 g/kg and phytate content ranged from 11.1 to 1.856 g/kg. The main -galactosides found in seeds were ra$nose, stachyose, verbacose and ajucose. Stachyose was the predominant sugar in the studied species. Therefore, these wild lupins could be considered a good source of protein after a suitable reduction in the content of alkaloids.
