The genus Hovea belongs to the tribe Genisteae of the plant family Leguminosae and it is endemic to Australia. It contains twelve species, six of which are found in south-western Australia. Previous chemical work on this genus appears to have been restricted to the isolation of (-)-sparteine (1) from the leaves of two Queensland species—H. longifolia R. Br. and H. acutifolia A. Cunn. H. elliptica (Sm.) DC. is a tall shrub, known locally as "blue bush", which grows in the karri forests of Western Australia. A methanolic extract of the leaves and terminal branches of this species has now yielded (+)-sparteine (I), (-)-lupanine (2), (-)-anagyrine (3), and (-)-cytisine (5), and the major alkaloid present in the seeds has been identified as (-)-cytisine (5). In 1955, Robinson suggested that the biogenesis of C₁₅ lupin alkaloids involves stepwise oxidative degradation of sparteine (1). This suggestion has been extended by Leete who has proposed the sequence (1) → (2) → (3) → (4) → (5). The present investigation appears to provide one of the few records of the isolation of (1), (2), (3), and (5) from the same plant. Although rhombifoline (4) could not be detected in the crude bases it seems that H. elliptica might prove to be a useful species for further biogenetic studies on these lupin alkaloids.
