Four new norditerpenes, taichunins A-D (1-4), were isolated from the fungus Aspergillus taichungensis (IBT 19404). Compound 1 has a new carbon framework. The absolute configurations were determined by the calculated ECD spectral method. Compound 1 was cytotoxic against HeLa cells with an IC50 value of 4.5 μM, whereas 2-4 were nontoxic at 50 μM.
