A survey of alkaloids from Cytisophyllum sessilifolium has shown the presence of several quinolizidine and dipiperidine alkaloids. The investigation afforded a new alkaloid, 7-hydroxylupanine. The structure of this alkaloid was assigned spectroscopically, α-Isosparteine, sparteine, β-isosparteine, ammodendrine, lusitanine, isolupanine, 5,6-dehydrolupanine, lupanine, a tentative dihydroxylupanine, cis-adenocarpine and trans-adenocarpine have been found. The co-occurrence of quinolizidine alkaloids and adenocarpine appears to be a good chemotaxonomic character of the genus Cytisophyllum. © 1991.
