| Abstract: | The mass spectra of diptocarpaine, diptocarpamine, diptocarpiline, and diptocarpidine, isolated fromDipthychocarpus strictus, have been studied. These compounds have proved to be derivatives of alkylureas, the substituents in them being mainly methylthio-n-hexyl and methylsulfinyl-n-hexyl radicals and the products of their chemical transformation. It has been established that mass-spectrometric fragmentation of these compounds takes place with the formation of heterocyclic ions.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.
