A novel compound (1) and 3 known compounds (2-4) were isolated from the fruiting bodies of Hypholoma fasciculare. The structure of 1 was determined by the interpretation of spectroscopic data. Compounds 2-4 were identified by comparing the spectra data of known compounds. In the bioassay examining growth inhibitory activity against phytopathogenic bacteria Clavibacter michiganensis, Burkholderia glumae, and Peptobacterium carotovorum, compounds 1, 2, and 4 showed inhibition effects on C. michiganensis only.
Keywords: Hypholoma fasciculare; isolation; mushroom; phytopathogenic bacterial activity; structural determination.
