Albumin is a simple protein present both in animal and plant physiological fluids and tissues. It plays many important roles including maintenance of appropriate osmotic pressure, binding and transport of various substances like hormones, drugs etc. in blood, and neutralisation of free radicals. Both acute and chronic disorders lead to hypoalbuminemia, oedema and many other disturbances. Albumin preparations obtained by separation of human plasma are used clinically for more than 50 years to reverse hypoalbuminemia and to allow for reversal of abnormalities in substance transport. These problems are discussed throught out this paper.

Electrophoretic analysis of seed albumins covered 201 accessions representing six subspecies of Vicia sativa L.: nigra, amphicarpa, incisa, sativa, macrocarpa and cordata. At least five individuals of each accession were examined separately. All the taxa under study showed variation with respect to albumin banding patterns, which was due to differences between accessions and individual variation within accessions. The number of albumin bands distinguished in particular taxa varied from 13 to 19. The statistical analysis of the electrophoretic data consisted in hierarchical grouping by the UPGMA method based on EUCLIDEAN distances. In the case of subsp. nigra and subsp. sativa, accessions originating from North Africa tended to form a group showing some distinctness from the remaining accessions. As to relationships among the studied taxa, subsp. nigra and subsp. cordata were shown to be the most closely related and their affinities to other members of the V. sativa aggregate were decreasing in the following order: subsp. macrocarpa, subsp. sativa, subsp. amphicarpa, subsp. incisa. The obtained results are discussed with reference to taxonomic relationships among the members of the V. sativa aggregate.
