From Thalictrum faberi, thalifaberidine [1], a new aporphine-benzylisoquinoline alkaloid, together with four known alkaloids, thalifaramine [2], thalifaricine [3], thalifarazine [4], and thalifaronine [5], were isolated. Thalifaberidine [1] was identified as 6',8-desmethylthalifaberine, and its 1H- and 13C-nmr data were completely assigned through the use of one- and two-dimensional nmr techniques. Thalifaberidine [1], thalifaberine [6], and thalifasine [7] showed cytotoxic activity against several human cancer cell lines, as well as antimalarial activity.
