To the best of our knowledge, the biological potential of many lichens has been unexplored, for this concept we aimed to estimate the antioxidant activity and the cytotoxicity of five different lichens collected from Japanese forests as well as tentative identification of the chemical profile of each species using liquid chromatograph coupled to high resolution mass spectrometer (LC-HRMS). This study shed the light of using such lichens as safe and effective preservatives in canned food industry.
