| Abstract: | Changes in the concentrations of vicine, convicine and L-DOPA in two cultivars ofVicia faba L. seeds in different stages of pod development were determined by high performance liquid chromatography (HPLC). The vicine and convincine conent was highest in fresh green cotyledons (moisture content about 80%) and gradually declined until a constant level was reached when seed dry matter percentage was around 40%. A similar pattern of variation in glucoside concentration was observed for the seed coat. The pods contained neither vicine nor convicine but they were particularly rich in L-DOPA. These compounds were not homogeneously distributed in the seeds. |
