Alcaloïdes des Loganiacées: sur l'isolement d'un nouvel alcaloïde à partir du Strychnos usambarensis

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.
