title: Phenolic compounds from the cultured mycobionts of Graphis proserpens.
abstract: Spore-derived mycobionts of the lichen Graphis proserpens were cultivated on a malt-yeast extract medium supplemented with 10% sucrose and their metabolites were investigated. Isocoumarin derivatives 1-3 and 7-oxo-5,7-dihydrooxepino[4,3,2-de]isochromene derivatives, proserins A-C (4-6), were isolated along with three known isocoumarin derivatives and three benzoic acid derivatives. Their structures were determined by spectroscopic methods.
