The new nematicidal compound, fly-dehydrocurvularin (1), together with three known compounds, alphabeta-dehydrocurvularin (2), 8-beta-hydroxy-7-oxocurvularin (3) and 7-oxocurvularin (4), were isolated from the culture filtrate and mycelial mats of Aspergillus sp. The structures of 1-4 were established by spectroscopic methods including 2D NMR. The biological activities of 1-4 were examined by bioassays with root-lesion nematodes, and lettuce and rice seedlings.
