OCCURRENCE IN HIGHER PLANTS OF 1-(3-AMINOPROPYL)-PYRROLINIUM AND PYRROLINE: PRODUCTS OF POLYAMINE OXIDATION

Article abstract of DOI:10.1016/0031-9422(86)88024-4

The presence of 1-(3-aminopropyl)pyrrolinium (App) has been established in the leaves of oats, maize, barley and wheat seedlings.In oat leaves, concentrations of 1,3-diaminopropane (Dap), putrescine (Put) and App were greatest in the youngest plants.Changes in Dap and App could not be correlated with changes in polyamine oxidase activity.Concentrations of the amines were smaller in maize than in oats, and smallest in barley and wheat.Pyrroline, an oxidation product of Put in pea seedlings and of spermidine in oat and maize seedlings, has been demonstrated in extracts of these plants, and also in spinach leaves and in radish shoots, following distillation, derivatization with 2-aminobenzaldehyde, oxidation of the adduct and GC-MS.Piperideine was also identified in pea seedlings.Key Word Index- Gramineae; Leguminosae; 1-(3-aminopropyl)-2-pyrrolinium; 1-pyrroline; 1-piperideine; 2-aminobenzaldehyde adduct; 2,3-trimethylene-4-quinazolone; spermine; diaminopropane; amine oxidases.
