Quaternary Alkaloids from Thalictrum minus subsp. elatum (JACQ.) STOY. et STEFANOV

Abstract

Quaternary alkaloids berberine (chloride, 0.18%) and, after transformation into the iodides, magnoflorine (iodide, 1.06%), jatrorrhizine (iodide, 0.066%), thalphenine (iodide, 0.040%) and thalifendine (iodide, 0.021%) were isolated, after separation of the tertiary bases (0.38%) from the root of Thalictrum minus subsp. elatum (JACQ.) STOJ. et STEFANOV of Czechoslovak origin (1.8% alkaloid content). The aerial parts (0.013% alkaloids) in their quaternary fraction contain only negligible amounts of magnoflorine, berberine, and coptisine (which is the first time coptisine was found in the Thalictrum genus).
