The seed of modern cultivars of Lupinus angustifolius normally contain less than 0.03% alkaloids. The acute oral LD, to rats of a pro rata mixture of the alkaloids of L. angustifolius seed was found to be 2279 mg/kg. For lupanine the LDS0 by oral administration was 1464 mg/kg and by intraperitoneal
Seed extracts obtained from Lupinus albus and Lupinus angustifolius by treatment with 48% ethanol contained ca. 10% alkaloids (on a dry weight basis) and were non-toxic. Their acute toxicity ( L D ~~) in the mouse is > 4000 mgkg-' body wt. After fractionation, the extract from L. angustifolius seed
