Two newbioactivemetabolites 1a and 2a (dinemasones A, B) were isolated in pure form and one as the diacetate 3b of dinemasoneC (3a) from the ethyl acetate extract of Dinemasporium strigosum together with the known palmitic acid, ergosterol and the cis and trans isomers of 4-hydroxymellein. The structures were determined by spectroscopic analysis, notably 2D NMR techniques. Their absolute configurations
