A rapid high-performance liquid chromatographic method for the separation of polyamines as their dansyl derivative has been developed. The chromatographic system used consisted of a reversed-phase column and a mobile phase of acetonitrile and water. The separation of 1,3-diaminopropane, putrescine, cadaverine, spermidine and spermine takes only 9 min. This method provides a good resolution between 1,3-diaminopropane and putrescine. It has been applied to quantify polyamines from seeds of wheat, petals of Phalaenopsis hybrids and various rat tissues.
