This work examined the content and distribution of the pyrimidine glucosides vicine and convicine, and the nonproteic amino acid l-DOPA in cotyledons and embryo axes along the germination and seedling growth of Vicia faba L. vars. Alameda and Brocal. The behaviour of these compounds was similar in both varieties. Vicine and convicine, implicated in favism disease, slowly declined in cotyledons. In embryo axis, vicine levels were sharply reduced and convicine amount was slightly increased as assay progressed. Total pyrimidine glucosides remained unchanged in the whole plant during the study. l-DOPA only appeared in the embryo axis of V. faba seeds and the highest content was observed in Brocal variety at 6 DAI (days after imbibition). The information provided in this study could be valuable for a possible role of embryo axis, rich in l-DOPA, for the treatment of Parkinson's disease and also as a choice ingredient for functional foods or as nutraceutical. © 2008 Springer-Verlag.
