Two new triterpene acids (1, 2), together with a complex mixture of lecithins (3), were isolated from the
fungus Gloeophyllum odoratum. Their structures were elucidated on the basis of extensive spectroscopic
analyses. The extract of Gloeophyllum odoratum considerably inhibited thrombin (72% at a concentration
of 120 g/mL); the less polar fraction of the methanolic extract from the mushroom exhibited interesting
activity (47% at a concentration of 120 g/mL) against thrombin. Compounds 1 and 2 were responsible for
this activity
