ESTER ALKALOIDS OF GENISTA-CINEREA SUBSPECIES CINEREA

Two ester alkaloids, cineverine and a new compound, for which we sugge st the name cineroctine, were isolated from twigs of Genista cinerea s ubsp. cinerea. Their structures were determined by spectroscopic metho ds to be 13 alpha-(3', 4'-dimethoxybenzoyl)oxylupanine (cineverine) an d 13 alpha-(3-hydroxy-cis-oct-5-enoyl)oxylupanine (cineroctine), 13-O- axial derivatives of lupanine. The distribution of these ester alkaloi ds amongst the different species of the section Spartioides of the gen us Genista is recorded.
