Dereplication of depsides from the lichen Pseudevernia furfuracea by centrifugal partition chromatography combined to 13C nuclear magnetic resonance pattern recognition.

•The major depsides of a lichen extract were directly identified within mixtures.•The initial extract was rapidly fractionated by CPC in the pH-zone refining mode.•Hierarchical clustering of 13C NMR signals resulted in the identification of depside molecular skeletons.•13C chemical shift clusters were assigned to structures using a 13C NMR database.•Six depsides were unambiguously identified by this approach.
