From Thalictrum faberi ten new aporphine-benzylisoquinoline dimers were isolated and the complete structures assigned by spectral methods. Of them, thalifaberine (1), thalifabine (2), thalifarapine (3), thalifabatine (4), thalifasine (5) and dehydrothalifaberine (6) ' constitute a new type of aporphine-benzylisoquinoline dimers. Huangshanine (7), faberonine (8), faberidine (9) and dehydrohuangshanine (10) are fetidine-type alkaloids. © 1984.
