A new depsidone of Lobaria pulmonaria with acetylcholinesterase inhibition activity

The phytochemical investigation conducted on a foliose lichen, Lobaria pulmonaria (L.) Hoffm. (Lobariaceae), led to the isolation of a new depsidone in the form of its diacetate derivative which showed a moderate acetylcholinesterase inhibition activity (1 mu g) in vitro. This is the first record of identified depsidone structure in searching for these inhibitors.
