Tha authors have isolated a new anhydronium base from Strychnos usambarensis. Its structure was elucidated thanks to the spectral data (UV,IR, MS and comparison with a synthetic product). Indeed the synthesis of the product was realized before the isolation from a plant ! Anhydronium bases are rare in Nature. [less ▲]

Six bis-indole alkaloids have been isolated from the rootbark of Strychnos usambarensis.Four alkaloids ( usambarensine and derivatives) are unsymmetrical bis-indole products, biogenetically derived from two tryptaminic and one monoterpene units as some alkaloids of Apocynaceae (Ochrosia) and Rubiaceae ( Uncaria), two families very close to Loganiaceae from a chemotaxonomy point of view. Two other alkaloids (C-dihydrotoxiferine and C_Curarine) are symmetrical bis-indole quaternary products. These potent compounds were previously isolated from calabash-curare and some American Strychnos. Furthermore, we have isolated loganic acid and discussed the part that it could take in the biogenesis of various alkaloids. [less ▲]
