Thermopsis montana

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.
