Conversion of 1, 8-cineole (1) by a strain of Aspergillus niger was investigated in connection with the biomass utilization of Eucalyptus plants. Two novel alcohols, 3-exo-(5) and 3-endo-hydroxycineole (6) were isolated from the culture broth and identified by interpretations of their spectral data. Furthermore, hydrogenolysis of 6 afforded p-methane-3, 8-e"-diol (8) which has been isolated as a plant growth inhibitor from Eucalyptus citriodora.
