Abstract: | A number of exometabolites have been isolated from the deuteromycetePyricularia oryzae Cav., of which harman and O-demethyldiaporthin have been isolated from this species for the first time. The latter is the
first example of a hexaketide from fungi of the genusPyricularia, for which only penta- and heptaketides have previously been described.
