The production of noble Eucalyptus oil from Eucalyptus leaves brings a mass of extracting wastewater pollutive to water environment. In order to better utilize and recover the productive wastewater from the Eucalyptus oil, we used pyrolysis- GC/MS to analyze the possible top value-added components of benzene/ethanol extractives of leaves of two Eucalyptus cultivars, i.e. E. dunnii and E. grandis. Relative content of each component was determined by area normalization. 22 compounds representing 92.12% of the benzene/ethanol extractive of E. dunn...
