Abstract
A search for flavonoid components in the seeds of four species of lupin, Lupinus albus, Lupinus angustifolius, Lupinus luteus and Lupinus mutabilis, revealed the presence in all of them of a single dominant compound, believed to be an apigenin di-C-glycoside. At levels varying from 0.16 mg (L. albus) to 0.37 mg (L. luteus) per 100 g of seed, this component seems unlikely to interfere significantly with protein utilisation or to confer anti-nutritional properties on lupinseed.
