The leaves and stems of Thermopsis montana Nutt. (T. fabacea Hook.) contain five alkaloids, four of which are also contained in the flowers and fruits. Three other alkaloids are also present in trace amounts in all parts of the plant. The five alkaloids isolated and characterised are cytisine and iV-methylcytisine (previously isolated ), hydroxylupanine, anagyrine, and thermopsine apparently iV-methylcytisine is not present in the flowers and fruits. Two of the minor alkaloids were tentatively identified as lupanine and 17-oxosparteine. 

The cytisine content of Thermopsis lanceolata and T. dolichocarpa has been studied by an ion-exchange method. Thermopsis chinensis Benth. =T. fabacea DC.) has previously also been shown to contain cytisine. Recently a total of five alkaloids has been isolated from the roots cytisine is present, together with iV-methylcytisine, anagyrine, lupanine, and N-formylcytisine. This last constituent has also been tentatively identified in the aerial parts of Euchresta japonica Benth. ... 

Quinohzidine alkaloids, hypothetically derived from quinolizidine (10-18), are a special group of bicyclic, tricyclic and tetracyclic secondary metabolites of some legumes, especially legumes of the genera Lupinus, Baptisia, Thermopsis, Genista, Cytisus, Chamae-cytisus. Laburnum and Sophora (Fabaceae), which occur as a complex mixture of several compounds. Quinolizidine alkaloids are...
