Eucalyptus smithii, wood, bark.Abstract
The material used in the present work came from 15 Eucalyptus smithii R. T. Baker trees grown in the experimental field of Embrapa Forests, in Colombo county, that were planted in 1988. The anatomical characterization of the wood and bark was accomplished using material prepared by Wood Anatomy and Identification Laboratory of IPT, and Wood Anatomy Laboratory of Federal University of Parana State. The essential oil extraction and analysis was made using ABNT procedures in the Phytochemistry Laboratory of Federal University of Parana State. The wood and bark of the Eucalyptus smithii had a homogeneous anatomical structure. In bark were found secretory cavities, but in wood they were not present, only quino veins and being the oil presence insignificant. The essential oil from bark had physical-chemistry characteristics in disagreement with international specifications for the eucalypt essential oils, rich in 1,8-cineole; therefore it is not economically viable to explore this component.
