Abstract
Three phytotoxic compounds were isolated from the culture broth of Chaetomium sp. through silica gel column chromatography and HPLC (RP-18). Their chemical structures were elucidated as chaetoglobosin F, chaetoglobosin C and chaetoglobosin E on the basis of instrumental analyses such as $^1H-NMR,\;^{13}C-NMR$, and HMQC. They inhibited the root growth of barnyard grass with the $IC_{50}$ values of 66, 65, and $67{\mu}g/ml$, respectively.
