Etude de guelques proprietes du systeme de desaturation des acides gras a chaine longue chez certains crustaces aguatigues.Heinen, Ernst  ; Dandrifosse, Guy in Archives Internationales de Physiologie et de Biochimie (1973), 81(1), 1-8 Detailed reference viewed: 26 (1 ULg)Observations of O(1D) and N(2D) emission in the polar auroraGérard, Jean-Claude ; in Physics and chemistry of upper atmospheres (1973) Detailed reference viewed: 6 (1 ULg) Alcaloïdes des Loganiacées: sur l'isolement de l'harmane à partir du Strychnos usambarensisAngenot, Luc ; ; in Plantes Médicinales et Phytothérapie (1973), 7(1), 33-36 Harman has been isolated for the first time from a species of the Family of Loganiaceae. MS data are provided as well as the list of plants where this product has een previously detected.

[more ▼] 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 ▲] Detailed reference viewed: 13 (2 ULg) Guide d'excursion.

[more ▼] 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.
