ALKALOIDS AND OTHER CONSTITUENTS FROM CROTON CHILENSIS

Croton chilensis Mull. Arg. is the only species from the large genus C roton of the family Euphorbiaceae growing in Chile. The isolation and identification of one aporphine and three morphinadienone alkaloids, o ne C-13 terpenoid and two C6-C2 aromatic compounds are reported. This is the first report on the occurrence of isosalutaridine (1), flavinan tine (2), O-methylfalvinantine (3), isocorydine (4), vomifoliol (5), t yrosol (6) and salidroside (7) in Croton chilensis. The structures wer e elucidated by their physical and spectroscopic data. The chemotaxono mic relevance of these secondary metabolites is discussed briefly.
