Characterization of Wood and Bark Extractives from Three Eucalyptus Species

    Research output: Contribution to conferencePaper


    Growing of eucalypti has already proven to be highly successful in countries with subtropical or Mediterranean climate like California and some countries of southern Europe like Portugal, Spain, and Italy. The eucalyptus plantations in Sicily have a potential of supplying western Europe with materials from short rotation forestry for lumber products, pulp and paper, biobased products, andspecialty chemicals from the extractives. Molecular beam mass spectrometry (MBMS) was used to characterize extractives from woods and barks of short rotation Eucalyptus globulus, Encalyptus occidentalis and Eucalyptus camaldulensis grown in Sicily. The yields of extractives were species dependent, but the chemical composition of the extractives from each morphological region was independent ofeucalyptus species. The amount of extractives in the barks were larger than those in the corresponding woods. The extractives from the bark ranged from 18.6% in E. globulus to 30.8% in E. occidentalis, whereas those in the wood ranged from 5.6% in E. occidentalis to 8.4% in E. camaldulensis. Ellagitanins were the predominant product identified by MBMS analysis of the benzene/ethanol extracts.
