Polarographic study of N-oxides of anabasine and N-methylanabasine

1. Polarographic reduction waves of anabasine and N-methylanabasine N-oxides were investigated and the nature of their dependence on solution pH and depolarizer concentration was studied. 2. It was established that there is a difference in the nature of the polarographic reduction of N-oxide groups at pyridine and N-methylpiperidine nitrogen, which makes it possible to use polarography to determine the position of an N→ O group in molecules with two tertiary nitrogen atoms differing in character.
