Abstract
Changes in the concentrations of vicine, convicine and L-DOPA in two c ultivars of Vicia faba L. seeds in different stages of pod development were determined by high performance liquid chromatography (HPLC). The vicine and convicine content was highest in fresh green cotyledons (m oisture content about 80%) and gradually declined until a constant lev el was reached when seed dry matter percentage was around 40%. A simil ar pattern of variation in glucoside concentration was observed for th e seed coat. The pods contained neither vicine nor convicine but they were particularly rich in L-DOPA. These compounds were not homogeneous ly distributed in the seeds.
