Merendera jolantae

The base (149) has been oxidized by electrochemical methods to the dibenzo-quinolizinium salt (150) the methoperchlorate, under similar conditions, is oxidized to a 2 2 dimer. A bisphenethylisoquinoline, jolantinine (151), has been isolated from Merendera jolantae its structure has been assigned on the basis of spectroscopic evidence. [Pg.121]

Reviews of this group are available in one of these, coverage is limited to alkaloids elaborated by the Wurmbaeoideae plants. Several new reports concerning exhaustive isolation studies of Colchicum species as well as of Kreysigia multijlora, Merendera fitifolia, and M. jolantae plants have appeared. For the most part, known colchicine alkaloids have been found although structures of several new ones have not been defined. A study of composition of alkaloids in Colchicum luteum at various stages of development has been described. [Pg.457]

Alkaloid from Colchicum autumnale, C. kesselringii, C. luteum, Merendera robusta and M. Jolantae (Liliaceae). Used as 0.02M CHCI3 soln. as an extractive indicator in the EDTA titration of Cu(/7) (pH 4.5). Needles (EtOAc). Sol. CHCI3. Mp 175-177°. [oef -256° (c,... [Pg.254]
