Abstract
Polyamines of the seeds, seedlings, and some other tissues of 15 leguminous plants were analyzed by high performance liquid chromatography and gas chromatography. A novel tertiary branched pentaamine, N5-aminobutylhomospermine, was detected in the seed of Vicia villosa and another novel quaternary branched pentaamine, N4-bis(aminopropyl)spermidine, in the seed of Crotalaria spectabilis. Norspermine and a novel linear pentaamine, caldopentamine, were found in the seed of Gleditschia japonica. Other unusual polyamines such as norspermidine, homospermidine, thermospermine, N4-methylthermospermine, homospermine, and N-(3-aminopropyl)aminopropanol occur widely within leguminous seeds. Nine groups of plant response were found with respect to increases of diaminopropane, putrescine, cadaverine, and agmatine in the leguminous seedlings after germination. Keywords: leguminae, seed, seedling, polyamine.
