Abstract Cultures of a fungicolous isolate of Sporormiella minimoides afforded two new polyketide metabolites which we have named sporminarins A (1) and B (2). The planar structures of 1 and 2 were elucidated by analysis of NMR and MS data, and by chemical methods. 1 exhibited significant antifungal activity against Aspergillus flavus.
