Polyamine alkaloids occurrence

Some of the plant species contain many different alkaloids, e.g., Lunaria biennis Moench. (Cruciferaceae). The investigation of this field of plant metabolites seems to have been done randomly and not systematically. Furthermore, the occurrence of di- and polyamine derivatives in many cultivated plants is apparent (123). Their structural differences from the more complicated alkaloids are not very large. It appears very probable that many more plants and animals contain di- and polyamine alkaloids than are known today. 

As for the components of Glycyrrhiza species, the essential oil (11, 38-40), and the occurrence of alkaloids (41-45), polysaccharides (46-62), a polyamine (63), triterpenes (64-67), fatty acids (6S) and amino acids (69) as well as triterpenoid saponins and flavonoids have...
