Z-Lobeline

Z-Lobeline, C22H2,OoN, separates from alcohol, ether or benzene in glistening needles, m.p. 130-1°, — 42-85° (EtOH), readily soluble in... 

Fragmentation of the molecular ion at m z 322 of norlobelanine led to product ions at m z 202 and 82. These fragment ions and their characteristic neutral losses 120 Da (322 —> 202) and 2x120 Da (322 82) indicated that two phenyl-2-ketoethyl side chains were present in the molecule. The daughter ion at m z 82 was 14 Da less than the daughter ion at m z 96 for lobeline, indicating that norlobelanine is a //-demethyl derivative of lobelia alkaloids.
