Abstract: The genus  Cinnamomum has been  collected  and  investigated  from  Hubei Province since  1982,  13 samples of essential oils  were  extracted  by steam distillation  from fresh leaves of the various species of Cinnamomum  and examined  qualitatively  and  quantita- tively by the method of capillary GC/MS/DS on Finnigan-4510  type.  108 compounds have been identified, of which 30 major constituents are selected as numerical chemotaxonomical characters, together with 17 morphological ones. The I3 samples were taken as operational taxonomic units (OTU’s).  Results obtained through R cluster analysis indicate the phenetic distance and regular correlation among the characters, especially between morphological and chemical ones.  Results obtained through Q cluster analysis show the relationships among the OTU’s. The Phylogenetic system of Cinnamomum in Hubei Province is also discussed in the present paper, based on the chemical constituents and the relationship mentioned above.Decontaminated thianthrene disproportion.
