Resumo
Corydines, isocorydines, and analogous aporphine alkaloids were isolated from the leaves of Aristolochia lagesiana var intermedia, together with three bisaporphine salts (lagesianines B-D) Their structures were determined by chemical derivatizations and spectroscopic analyses Lagesianines B and C are the first examples of N-CH(2)-N' and C-2-O-C-1' linked dimeric aporphine alkaloids, respectively, while the monomeric units of lagesianine D. which has a carbon skeleton, are linked through C-7-C-5' via ail ethane-1,2-diol group (C-7-CHOHCHOH-C-5') (C) 2009 Elsevier Ltd.
