Amides are important natural products which occur in a few plant families. Piplartine and piperine, major amides in <i>Piper tuberculatum</i> and <i>P. nigrum</i>, respectively, have shown a typical N-CO cleavage when analyzed by EI-MS or HRESI-MS. In this study several synthetic analogs of piplartine and piperine were subjected to both types of mass spectrometric analysis in order to identify structural features influencing fragmentation. Most of the amides showed an intense signal of the proto ...[more]
