Summary

The alkaloids ofMerendera iolantae E. Czerniak have been studied for the first time. The total alkaloids consist of tropolone compounds and bases without a tropolone ring. From this plant we isolated the known alkaloids colchicine, colchamine, β-lumicolchicine, colchameine, and 2-demethylcolchiceine, and four new, nontropolone, bases — MI-1 (iolantamine), MI-2, MI-3, and MI-4. The presence of colchiceine, 3-demethylcolchamine, and two unknown bases with R f 0.49 and 0.53 was shown by chromatographic methods.

A developed formula has been put forward for iolantamine on the basis of its spectral characteristics.
