Three undescribed bisabolane sesquiterpenoids, zopfiellins A–C (1‒3), and one new α-pyrone derivative, zofiellone (4), have been isolated from cultures of the endophytic fungus Zopfiella sp. Compound 2 is a rare trinor-bisabolane sesquiterpenoid and 3 has an unusual aromatic core. Compounds 3 and 4 possess mild cytotoxicities against three human cancer cell lines with a range of IC₅₀ values from 12.3–27.3 μM.
