Alkaloids of Thalictrum. XXI. Isolation and characterization of alkaloids from the roots of Thalictrum podocarpum. Wu, Wu-Nan; Beal, Jack L.; Leu, Ruey-Ping; Doskotch, Raymond W. (Coll. Pharm., Ohio State Univ., Columbus, Ohio, USA). Lloydia, 40(4), 384-94 (English) 1977. CODEN: LLOYA2. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11, 31 Thirteen alkaloids, isothalidezine (I) [64924-28-3], N-demethylthalidezine (II) [65230-06-0], hernandezine [6681-13-6], thalidezine [18251-36-0], thalistyline [62251-53-0], thalistyline methodiiodide [62251-50-7], N-demethylthalistyline [62251-51-8], berberine [2086-83-1], columbamine [3621-36-1], jatrorrhizine [3621-38-3], palmatine [3486-67-7], thalifendine [18207-71-1], magnoflorine [2141-09-5], and an artifact 8-trichloromethyldihydroberberine [50932-22-4] were isolated from T. podocarpum roots. In addn., oxyberberine [549-21-3] and thaliglucinone [35988-96-6] were obtained in very minor amts. I and II are new bisbenzylisoquinoline alkaloids. Hernandezine, thalistyline, thalidezine, thalistyline methodiiodide, and N-demethylthalistyline had activity against Mycobacterium smegmatis at 100 mg/mL or less. Five alkaloids possessed hypotensive activity.

ISSN: 0031-6903. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Berberine (I) [2086-83-1], magnoflorine [2141-09-5], jatrorrhizine [3621-38-3], palmatine [3486-67-7], coptisine [3486-66-6], and some unidentified alkaloids of Coptidis rhizome (Coptis joponica) were sepd. by high-speed chromatog. on starch gel using H2O-MeCN-AcOH-Et3N (:0.3:0.745) solvent system. I as well as palmatine and coptisine contents in wild and com. Coptis rhizome could also be detd. by the same procedure. The alkaloids of Phellodendron cortex were also detd.
