Abstract

© 2017, Springer-Verlag Berlin Heidelberg. A new depside was identified in the methanolic extract from the lichen Everniopsis trulla based on the metabolomics UHPLC–DAD–MS analysis and HESI–MS–MS fragmentation patterns along with thirty-two known compounds for the first time. The compounds were structurally characterized by UV and high resolution quadrupole orbitrap mass spectra and by comparison with literature. According to the characteristic fragmentation patterns, the presence of two simple aromatic compounds, six lipid derivatives, eight depsidones, thirteen depsides, a chromone, two diphenylethers, and a dibenzofuran were identified. To our knowledge, this is the first study of the lichen E. trulla by liquid chromatography hyphenated with tandem mass spectrometry.
