With the use of GC-MS, the resolution and identification of alkaloids occurring in the seeds of six species of wild Mexican lupins has been achieved. From among 46 detected compounds it was possible to identify unambiguously 24 of them. Most of identified alkaloids are from the lupanine group. The percentage content of particular alkaloids in comparison with the total alkaloid pool (ranged from 2.0 to 3.5%) in the species tested has also been determined. Alcoholic extract from Lupinus exaltatus seeds (ALP) with low RFOs and sucrose content, introduced in different doses (80, 320 and 1600 mg d.w./pot.) to soil has increased paprika fruit yield (for doses 320 and 1600 mg/pot) and its vegetative mass (for all applied doses). The experiments were carried out in greenhouse in controlled conditions within a period of March-December 2001. © 2003 Elsevier B.V. All rights reserved.
