Terpenoids from the mushroom-associated fungus Montagnula donacina

A chemical re-investigation of the culture broth of this fungus resulted in the isolation of four rare tetracyclic bergamotane-type sesquiterpenoids, namely donacinolides A and B, donacinoic acids A and B, and three cadinane-type ones, namely donacinols A–C and a meroterpenoid...
