Two ester alkaloids, cineverine and a new compound, for which we suggest the name cineroctine, were isolated from twigs of Genista cinerea subsp. cinerea. Their structures were determined by spectroscopic methods to be 13 alpha-(3', 4'-dimethoxybenzoyl)oxylupanine (cineverine) and 13 alpha-(3-hydroxy-cis-oct-5-enoyl)oxylupanine (cineroctine), 13-O-axial derivatives of lupanine. The distribution of these ester alkaloids amongst the different species of the section Spartioides of the genus Genista is recorded.
