Four new bisbenzylisoquinoline alkaloids were obtained from Albertisia cf.A. papuana Becc. (Menispermaceae).These are (-)-2,2'-bisnorphaeanthine (5), (+)-pangkoramine (7), (+)-pangkorimine (9), and (+)-2'-norcocsuline (14).They are accompanied by the known (+)-daphnoline (2), which is the main alkaloid, and by seven known dimers with one, two, or three ether bridges
