Les lichens, organismes symbiotiques associant un champignon et un partenaire photosynthétique (algue verte et/ou cyanobactérie), sont caractérisés par la biosynthèse de métabolites secondaires uniques dotés de bioactivités variées. Pour valoriser au mieux cette ressource privilégiée, des méthodes innovantes de spectrométrie de masse ont été développées dans le but de minimiser la préparation de l’échantillon et la durée des analyses. Deux techniques de spectrométrie de masse ont été évaluées en ce sens : le DART-MS et le LDI-MS. L’apport de chacune de ces deux méthodes a pu être établi sur un large panel de lichens, représentant une part importante de l’espace chimique couvert par ces organismes. Il a été démontré que des profils chimiques...
