Abstract: Using electrospray ionization(ESI) and tandem mass spectrometry techniques, the protonic positions in protonated molecular ions of some narcotic drugs were studied. The data of ESI/MSnexperiments of morphine and deuterium-loaded morphine were first discussed. The protonic position was considered to locate on oxygen atom of cyclic ether in morphine molecular. Compared with the same and different ions among morphine, codeine, acetylcodeine and dihydrocodeine, the protonic positions in protonated molecular ions of these compounds were further determined. The fragmentation mechanism of morphine in ESI/MSnexperiments was also repored in the paper, and there were similar dehydrolysis mechanism in gas phase or in liquid phase for morphine.

Key words: Electrospray ionization, Tandem mass spectrometry, Narcotic drugs
