The alkaloid composition of the bulb casing of Merendera robusta Bge. (Liliaceae) was investigated. The tropolone alkaloid colchicine was identified. A new homoaporphine base for which the structure methylmerenderine hydroxide was established by spectral and chemical methods was isolated.

The alkaloid complex of the leaves, stems, seeds, and seed pods ofMerendera raddeana Rgl. (familyLiliaceae) has been investigated. A number of known tropolone alkaloids and their photochemical isomers have been isolated together with the homoaporphine bases merenderine, kreysiginine, and O-methyl-kreysiginine and their N-oxides, which have not been described in the literature. One of them (merenderine
