 Title    A Survey of Alkaloids in Spartium junceum L. (Genisteae-Fabaceae)  
 Abstract    The alkaloid pattern of Spartium junceum has been investigated. Cytisine, N-methylcytisine, anagyrine, rhombifoline and epi-baptifoline occur as major compounds in most of the samples studied. Considerable quantitative differences were found between various parts of the plant. The alkaloid content changed strongly dependent on the seasons. Only a limited variation can be ascribed to geographical origin.

 Title    Alkaloids of Adenocarpus hispanicus (Lam.) DC Varieties  
 Abstract    A lkaloid extracts from different organs o f Adenocarpus hispanicus ssp. hispanicus and A de­ nocarpus hispanicus ssp. gredensis were analyzed by capillary GC. Twenty-four com pounds could be identified by the high sensitive method o f GLC-M S: the pyrrolizidine alkaloids de-corticasine, N -acetylnorloline and N-butyrylnorloline, the bipiperidyl alkaloid amm oden-drine, the phenylethylamine tyramine and 19 quinolizidine alkaloids. In contrast to Adenocar­ pus com plicatus, Adenocarpus foliolosus and Adenocarpus viscosus the alkaloid pattern o f A de­ nocarpus hispanicus is characterized by the occurrence o f quinolizidine alkaloids with sparteine predominating in the leaves and numerous dehydroderivatives o f sparteine. Remarkable is the total absence o f adenocarpine which was described as a main com pound o f the three former species. Our results strongly support the opinion that the genus Adenocarpus should be divided into two phytochem ical groups.
