摘要：

Spore-derived mycobionts of the lichen Pyrenula sp. were cultivated on a malt-yeast extract medium supplemented with 10% sucrose and their metabolites were investigated. A new naphthopyrone derivative, pyrenulin, as well as toralactone were isolated. Their structures were determined by spectroscopic methods. This is the first instance of the isolation of naphthalene derivatives from lichen mycobionts.
