One new natural product, cadinane-type sesquiterpenoid, (±)-(2S*,3S*)-dihydroxy-α-corocalene (1), has been isolated from the endophytic fungus Curvularia intermedia, derived from the plant Oryza sativa. The structure was determined using spectroscopic methods, mainly 1D and 2D NMR, and comparison of the spectroscopic data with those reported for structurally related compounds.
