A New Lichen Depsidone from L Obaria Pulmonaria

The continuation of our phytochemical survey of Lobaria pulmonaria (L.) Hoffm. (Lobariaceae), has led to the isolation and identification of a new lichen depsidone (1) characterised by the normal analytical and spectroscopic techniques. Unlike previously isolated depsidone (2) from the same species, the compound 1 has not showed activity in the acetylcholinesterase inhibition test on Thin-layer chromatography plate.
