The mass spectrometric behavior of three depsidones isolated from Lichen was studied by electrospray tandem mass spectrometry, showing that these compounds in ESI-MSn could produce many daughter ions. Their fragmentation pathways reflected their structural character.

Key words: depsidone, ESI-MS, MSn, fragmentation pathway
