    • Chemistry and biological activity of alkaloids from the genus Schizanthus 
      Christen, Philippe; Cretton, Sylvian; Humam, Munir; Bieri, Stefan; Muñoz Muñoz, Orlando; Joseph-Nathan, Pedro (Springer, 2020)
      The genusSchizanthus(Solanaceae) comprises 12 accepted species primarily endemic to Chile. It is characterized by the presence of numerous tropane alkaloids found as ester derivatives of isomeric acids like angelic, ...
    • In vitro shoot and root organogenesis, plant regeneration and production of tropane alkaloids in some species ... 
      Jordan, Miguel; Humam, Munir; Bieri, Stefan; Christen, Philippe; Poblete, Estrella; Muñoz Muñoz, Orlando (PERGAMON-ELSEVIER SCIENCE LTD, 2006-03)
      A rapid in vitro propagation system leading to formation of shoots from callus, roots, and plantlets was developed for Schizanthus hookeri Gill. (Solanaceae), an endemic Chilean plant. The genus Schizanthus is of particular ...
    • Isomeric Tropane Alkaloids from the Aerial Parts of Schizanthus tricolor 
      Cretton, Sylvian; Glauser, Gaetan; Humam, Munir; Jeannerat, Damien; Muñoz Muñoz, Orlando; Maes, Louis; Christen, Philippe; Hostettmann, Kurt (AMER CHEMICAL SOC, 2010-02-18)
      Investigation of the aerial parts of Schizanthus tricolor yielded seven isomeric tropane alkaloids: 3 alpha-(1-methylitaconyl)-6 beta-senecioyloxytropane 3a-(1-methylitaconyl)-6 beta-angeloyloxytropane (2), 3 alpha-(1-me ...
    • Schizanthines N, O, and P, Tropane Alkaloids from the Aerial Parts of Schizanthus tricolor 
      Humam, Munir; Kehrli, Thomas; Jeannerat, Damien; Muñoz Muñoz, Orlando; Hostettmann, Kurt; Christen, Philippe (AMER CHEMICAL SOC, 2011-01)
      Three tropane alkaloids, named schizanthines N, O, and P (1-3), have been isolated from the crude alkaloid extract of the endemic Chilean plant Schizanthus tricolor. On the basis of extensive NMR studies and MS fragmentation ...
    • Tropane alkaloids of the aerial parts of Schizanthus tricolor 
      Humam, Munir; Muñoz Muñoz, Orlando; Christen, Philippe; Hostettmann, Kurt (2007)
      The alkaloid profile of the aerial parts of Schizanthus tricolor Grau et Gronbach was investigated by GC-MS. Seventeen alkaloids were detected and are reported in this species for the first time. They were identified by ...
