title: Alkaloids of Thalictrum. XV. Isolation and identification of the hypotensive alkaloids of the root of Thalictrum lucidum.
abstract: Sixteen alkaloids, namely homoaromoline, obaberine, O-methyl-thalicberine, oxyberberine, thalidasine, thaliglucinone, thalrugosine, obamegine, oxyacanthine, berberine, columbamine, jatrorrhizine, magnoflorine, palmatine, thalifendine and base A chloride, plus the artifact, 8-trichloromethyldihydroberberine, were isolated from the alkaloid fraction of the roots of Thalictrum lucidum L. Of these, obamegine, thalrugosine, O-methylthalicberine, thaliglucinone, obaberine and homoaromoline were found to possess hypotensive activity in normotensive dogs. Thalidasine, homoaromoline, thalrugosine, thaliglucinone, obamegine, jatrorrhizine, and columbamine were found to possess antimicrobial activity against Mycobacterium smegmatis at a concentration of 100 mug/ml or less.
