Alkaloids of callus tissues and redifferentiated plantlets in the papaveraceae

The callus tissues from 11 representative species of the Papaveraceae and the redifferentiated plantlets from four species were successfully derived and maintained. The alkaloids in the callus tissues and redifferentiated plantlets were examined in comparison with those of the original plants. All the callus tissues are similar in their alkaloid chemistry and contain benzophenanthridine, protopine and aporphine type alkaloids. By contrast, the plantlets have a more specific alkaloid pattern, being similar in content to the original plants.
