In the course of our chemical screening program for new secondary metabolites, we isolated new compounds JBIR-37 (1) and -38 (2) from a culture broth of the marine sponge-derived fungus, Acremonium sp. SpF080624G1f01. The structures of 1 and 2 were determined to be di- and mono-O-β-D-glucopyranosyloxy-4-(1,1-dimethyl-2-propenyl)benzene on the basis of extensive NMR and MS spectroscopic data, respectively.
