The structures of orixidine and orixidinine, both demethylation products of orixine, were discussed and their 2(1H)-quinolone structures were established. It is assumed that orixidine and orixidinine should have structures (IV) and (XIII), respectively, while that of the isomeric transformation product of (XIV), iso-N-methylorixidinine, structure (XVI).
