Lichens are widely distributed symbiotic organisms producing unique chemical compounds with interesting biological properties. The secondary metabolites of lichens, which are tailored to live in the most extreme conditions, are highly attractive for the pharmaceutical and cosmetic industries. The need for continuing research in the identification of new metabolites, the studies of their potential and mechanisms of action as well as their large scale production requires effective and greener extraction processes. This review presents a survey of the conventional and advanced extraction technologies reported for obtaining lichen bioactives. Due to the complex lichen morphology, the influence of different strategies causing the cell degradation for aiding in the extraction of solutes are discussed.
