A new ubiquinone homologue was isolated from Chaetomium funicola JS 525. Its chemical structure was found to be 2, 3-dimethoxy-5-methyl-6-IX, X-tetrahydrofarnesylfarnesylgeranylgeranyl-1, 4-benzoquinone based on the results of mass and 1H-NMR spectra containing a spin decoupling experiment. This fungus also contains dihydrogenated ubiquinone with ten isoprene units as a minor component, and this ubiquinone was presumed to be composed of two different homologues saturated at the 9th and 10th (terminal) units from a benzoquinone ring.
