To date only a few are known; these include Jerusalemine and Salimine. Jerusalemine may be formed through decarbonylation xlix of the tropolone ring of 2-Demethyldemecolcine by a peroxidase system present in the plant, with accompanying oxidation. Salimine, on the other hand, may arise from Colchicine by enzymatic peroxidation of ring C followed by hydroxylation and methylation.
